Onerous Drives: ATA versus SATA

The efficiency of laptop programs has been steadily rising as sooner processors, reminiscence, and video playing cards are constantly being developed. The one key part that’s typically uncared for when taking a look at bettering the efficiency of a pc system is the arduous drive. Onerous drive producers have been continuously evolving the fundamental arduous drive utilized in trendy laptop programs for the final 25 years, and the previous couple of years have seen some thrilling developments from sooner spindle speeds, bigger caches, higher reliability, and elevated knowledge transmission speeds.

The drive kind used most in shopper grade computer systems is the hearty ATA kind drive (generally referred to as an IDE drive). The ATA commonplace dates again to 1986 and relies on a 16-bit parallel interface has undergone many evolutions since its introduction to extend the velocity and measurement of the drives that it might help. The newest commonplace is ATA-7 (first launched in 2001 by the T13 Technical Committee (the group chargeable for the ATA commonplace)) which helps knowledge switch charges as much as 133MB/sec. That is anticipated to be the final replace for the parallel ATA commonplace.

As way back as 2000 it was seen that the parallel ATA commonplace was maxing out its limitations as to what it may deal with. With knowledge charges hitting the 133MB/sec mark on a parallel cable, you might be inviting all types of issues due to sign timing, EMI (electromagnetic interference) and different knowledge integrity points; thus trade leaders received collectively and got here up with a brand new commonplace referred to as Serial ATA (SATA). SATA has solely been round just a few years, however is destined to change into “the usual” attributable to a number of advantages to be addressed on this Tech Tip.

The 2 applied sciences that we’ll be taking a look at are:

ATA (Superior Know-how Attachment) – a 16-bit parallel interface used for controlling laptop drives. Launched in 1986, it has undergone many evolutions within the final 18+ years, with the most recent model being referred to as ATA-7. Wherever an merchandise is known as being an ATA machine, it’s generally a Parallel ATA machine. ATA gadgets are additionally generally referred to as IDE, EIDE, Extremely-ATA, Extremely-DMA, ATAPI, PATA, and so forth. (every of those acronyms truly do discuss with very particular objects, however are generally interchanged)

SATA (Serial Superior Know-how Attachment) – a 1-bit serial evolution of the Parallel ATA bodily storage interface.

Primary Options & Connections

SATA drives are straightforward to differentiate from their ATA cousins by the totally different knowledge and energy connections discovered on the again of the drives. A side-by-side comparability of the 2 interfaces could be seen on this PDF from Maxtor, and the next covers lots of the variations…

Commonplace ATA drives, corresponding to this 200GB Western Digital mannequin, have considerably cumbersome, two inch huge ribbon cable with 40-pin knowledge connections and obtain the 5V essential to energy them from the acquainted 4-pin connection. The essential knowledge cables for these drives have appeared the identical for years. A change was made with the introduction of the ATA-5 commonplace to raised enhance the sign high quality by making an 80 wire cable used on the 40-pin connector (these are generally referred to as 40-pin/80-wire cables). To enhance airflow throughout the laptop system some producers resorted to actually folding over the ribbon cable and taping it into that place. One other latest bodily change additionally got here with the arrival of rounded cables. The efficiency of the rounded cables is the same as that of the flat ribbon, however many favor the improved system air move afforded, ease of wire administration, and cooler look that include them.

SATA drives, corresponding to this 120GB Western Digital mannequin, have a half inch huge, 7 “blade and beam” knowledge connection, which ends up in a a lot thinner and simpler to handle knowledge cable. These cables take the comfort of the ATA rounded cables to the subsequent degree by being even narrower, extra versatile and able to being longer with out concern of information loss. SATA cables have a most size of 1 meter (39.37 inches), which is far better than the beneficial 18 inch cable for ATA drives. The lowered footprint of SATA knowledge connections frees up area on motherboards, doubtlessly permitting for extra handy layouts and room for extra onboard options!

A 15-pin energy connection delivers the 250mV of obligatory energy to SATA drives. 15-pins for a SATA machine appears like it will require a a lot bigger energy cable than a 4-pin ATA machine, however in actuality the 2 energy connectors are nearly the identical peak. In the interim, many SATA drives are additionally coming with a legacy 4-pin energy connector for comfort.

Many trendy motherboards, corresponding to this Chaintech motherboard, include SATA drive connections onboard (many additionally together with the ATA connectors as properly for legacy drive compatibility), and new energy provides, corresponding to this Extremely X-Join, usually function just a few of the required 15-pin energy connections, making it straightforward to make use of these drives on new programs. Older programs can simply be upgraded to help SATA drives by use of adapters, corresponding to this PCI slot SATA controller and this 4-pin to 15-pin SATA energy adapter.

Optical drives are additionally changing into extra available with SATA connections. Drives such because the Plextor PX-712SA reap the benefits of the brand new interface, though the efficiency won’t be any better than a comparable optical drive with an ATA connection.


Along with being extra handy to put in and drawing much less energy, SATA drives have efficiency advantages that actually set them other than ATA drives.

Probably the most attention-grabbing efficiency function of SATA is the utmost bandwidth doable. As we now have famous, the evolution of ATA drives has seen the info switch charge attain its most at 133 MB/second, the place the present SATA commonplace supplies knowledge transfers of as much as 150 MB/second. The general efficiency improve of SATA over ATA can at the moment be anticipated to be as much as 5% (in line with Seagate), however enhancements in SATA expertise will certainly enhance on that.

The way forward for SATA holds nice issues for these wanting much more velocity, as drives with 300 MB/second switch charges (SATA II) can be available in 2005, and by 2008 speeds of as much as 600 MB/second could be anticipated. These speeds are unimaginable, and are arduous to think about at this level.

One other efficiency profit discovered on SATA drives is their built-in hot-swap capabilities. SATA drives could be introduced on and offline with out shutting down the pc system, offering a critical profit to those that cannot afford downtime, or who need to transfer drives out and in of operation shortly. The upper variety of wires within the energy connection is partially defined by this, as six of the fifteen wires are devoted to permitting the hot-swap function.


Evaluating ATA drives to SATA drives could be tough given the entire variables, however usually it’s the case that SATA drives will nonetheless price only a bit greater than a comparable ATA drive. The hole is closing quickly although, and as SATA drives achieve in reputation and availability a definite shift in costs could be anticipated. Contemplating the advantages of SATA over ATA, the potential distinction of some {dollars} can simply be justified when contemplating an improve. Laptop Geeks at the moment has a restricted number of SATA drives, however a number of technical websites, corresponding to The Tech Zone and The Tech Lounge, provide actual time value guides to see how comparable drives stack up.

Remaining Phrases

The present SATA commonplace supplies important advantages over ATA when it comes to comfort, energy consumption and, most significantly, efficiency. The primary factor ATA has going for it proper now’s historical past, because it has been the usual for thus lengthy that it’s going to not going disappear any time quickly. The way forward for SATA can be much more attention-grabbing as velocity will increase will assist arduous drive improvement maintain tempo with different key system elements.

The Genesis of Laptop Artwork-FORTRAN (Backus) a Laptop Artwork Medium Creates a Mosaic Mona Lisa

The place did pc artwork, pc graphics and pc animation start?

Written communication turned sharable and pervasive as soon as stone etchings have been changed with the mobility of paper and ink. Equally as soon as pc languages superior from machine or meeting code to 3rd technology pc languages, solely then did pc output advance from easy alphanumerical (possibly mosaic) printouts to graphics and pictures with easy curves and realism.

Laptop graphical output acquired its humble begin when alphanumeric characters hammered on TTY and line printers to characterize X-Y graphs and even mosaic photos. It was crude, however allowed for a simpler evaluation of mathematical and scientific options. Laptop programming languages like FORTRAN and BASIC made it simpler to develop and program printers, plotters and CRT screens to show and print graphics and in the end photos.

The FORTRAN programming language – a private and historic brief assessment.

FORTRAN programming as an Artwork Medium?

So it was attainable to create an alphanumeric printout image of the well-known Mona Lisa utilizing FORTRAN print statements. This picture of the Mona Lisa was finished by printing and over-printing commonplace alphanumeric characters making a mosaic artwork piece to kind a picture of that well-known Leonardo da Vinci portray. Step again from this pc printout and also you considered a easy duplicate of Leonardo da Vinci’s Mona Lisa.

Engaging in this rudimentary pc artwork could be hours and days of tedious work involving the next steps:

1) You would wish to take a replica of the unique picture and a grid (mapping to the 133 character width of a normal pc printout web page) on a bit of transparency.

2) Place the grid transparency on high of the picture after which fill within the grid cells over the picture with alphanumeric characters that may depict a mosaic of the unique picture.

3) Spotlight these grid cells that shall be overprinted (daring sort) to create shade and texture matching the unique picture.

4) Now you’re taking every line of the grid and code it utilizing FORTRAN print statements.

5) Like a brush to canvas the pc printout picture of Mona Lisa will take kind after many days of coding.

For a accomplished model of this course of and a ensuing pc mosaic of the Mona Lisa try the Pisaca Net Albums photos at: http://picasaweb.google.com/carl.chesal/MonaLisaComputerArtFortran

The search has begun for entry to an 80 column punch card reader.

The FORTRAN code for the Mona Lisa Mosaic is on unique 90-column punch playing cards. Having access to an 80-column card reader may facilitate shifting the Mona Lisa FORTRAN code from its analog state to a digital model. Utilizing a web based editor, I may as soon as once more deploy the ability of FORTRAN to print copies of ‘pc mosaic’ Mona Lisa. Then ‘Mosaic Mona’ could be out there for the world to get pleasure from.

My infatuation with FORTRAN programming may need stemmed from the truth that each FORTRAN and I have been coincidentally created in 1954. Thanks John Backus for FORTRAN.

Residing With Your Grandparents - Bridging the Era Hole at House

Grandparents elevating grandchildren home greater than 4.9 million youngsters? For my part there’s not that a lot distinction in elevating children at this time so far as the fundamental wants that have to be meet. Now if you wish to discuss a era aside we’ll discuss computer systems and way of life. For many grandparents computer systems would possibly as nicely be from one other planet. I personally beginning utilizing a pc after I was in my mid thirties and I believe the going age at this time is about 2. How neat is that however for grandparents they should discover methods to bridge the gaps to allow them to elevate their grandchildren. We’ll make a listing beneath.

Grandparents Can Do

  • To begin with why not go to the supply: Ask the grandkids to show you tips on how to use a pc
  • Take a pc class at your senior heart
  • Be open to conversations even in case you don’t know or perceive the subjects: Pay attention
  • Discover a native group for grandparents elevating grandchildren to share your tales
  • Ask if their faculty or church has a program for fogeys and be concerned
  • Hold an open thoughts to new concepts
  • Attempt new issues your grandchildren recommend
  • Be affected person

Grandchildren Can Do

I can keep in mind issues that my papaw use to inform me (I walked 5 miles within the snow to get to highschool) and I now perceive they he was telling the reality. I’ve advised my very own children how we had out of doors bogs till I used to be within the sixth grade they usually simply giggle and say (no one ever use to go to an outhouse to make use of the lavatory) oh mother. I don’t know why that story is so humorous, you’d suppose I advised a joke.

What’s Intelligence? The Three Most important Theories of Intelligence – Two Good, One Unhealthy

What's Intelligence? The Three Most important Theories of Intelligence - Two Good, One Unhealthy
What's Intelligence? The Three Most important Theories of Intelligence - Two Good, One Unhealthy

When folks speak about an individual’s ‘intelligence’ it isn’t typically clear what underlying means or skills this time period refers to. This text is meant to make clear in layman’s phrases what psychologists and mind scientists can imply by intelligence. Principally, there are two good theories–and scientists are divided on which is one of the best theory–and one unhealthy one which all scientists I do know of reject. An excellent idea is one that’s supported by the proof; a foul idea is one that’s not.

Official IQ exams such because the WAIS-IV declare to measure particular person variations in an underlying ‘ stage of cognitive means given by a single number–your IQ or intelligence quotient. However is it true that there’s a single underlying psychological means that we differ in and that explains what makes us totally different in our cognitive skills? If somebody is sweet at maths, are in addition they more likely to be good at language comprehension, reasoning, pondering analogically, studying languages and common data, as a result of their underlying ‘intelligence stage’, as this idea implies?

Or are there ‘a number of intelligences’ underlying out abilities–perhaps dozens and even a whole lot of them–each unbiased from one another, and measured by several types of take a look at. You probably have a capability in arithmetic, is that this means fully unrelated to your means in studying languages or play common data video games like trivial pursuit? If that is so, is the concept of getting a single IQ rating fairly meaningless? Or alternatively, are there a small variety of underlying cognitive skills (maybe two or three) that we differ in, that are comparatively unbiased from every other–and which collectively clarify most the variations in our cognitive skills?

1. The speculation of common intelligence (g)–a good idea

A protracted standing an influential idea for our cognitive skills states that underlying all our cognitive skills (math, language comprehension, common data) is a single factor–called common intelligence (also referred to as unitary intelligence, common cognitive means, or just ‘g’ ) that people differ on and which explains these variations.

Spearman (1923) proposed that underlying all cognitive skills a ‘common means’ issue (g) that each one the skills draw on. People differ in g in line with a bell curve distribution on this idea. g could be considered when it comes to data processing energy. Some folks –those with increased g–can course of extra data, extra effectively than others. Utilizing a pc analogy, they’ve extra RAM. The extra RAM a pc has, the extra advanced and information-intensive the applications that may be run on it. You probably have an IQ of 160 like Quentin Tarantino has, you’ve gotten numerous RAM, giant ‘bandwidth’ for processing data. You probably have an IQ of 78 like Muhammad Ali as a younger man (whose IQ was measured by the military), then you’ve gotten much less RAM. Muhammad Ali had many skills, however in line with the unitary intelligence idea, intelligence wasn’t one in all them.

The proof for this idea is identical proof that permits us to reject the speculation of a number of intelligences. All standardized exams of cognitive means (and there are dozens of them, measuring a variety of various skills) are positively correlated–not completely, however to a big diploma. Which means if somebody scores increased than common on a type of exams, they’re more likely to rating increased than common on all the opposite tests–even ones that seem completely unrelated. Scoring increased in an arithmetic take a look at means you’ll in all probability additionally rating increased in a vocabulary take a look at. This stays true, even if you take different components like instructional background, or household socioeconomic standing under consideration. That is compelling proof that there’s a single underlying stage of cognitive means that’s utilized to every of the exams and that efficiency on one take a look at isn’t unbiased from efficiency on one other because the a number of intelligence idea claims.

Spearman (1904)–the psychologist who first proposed the g theory–argued that the variance (the individual to individual variation) of efficiency between people on ANY cognitive job could be attributed to only two underlying components: g (common intelligence) and s –the talent distinctive to that specific job. An individual may make investments comparatively extra time into creating a selected talent reminiscent of arithmetic, and this may elevate their rating on an arithmetic take a look at relative to a different take a look at reminiscent of vocabulary that they did not practice or follow on, however their common intelligence g will nonetheless account for many of their efficiency on the arithmetic take a look at. G continues to be a very powerful think about explaining ranges of efficiency, regardless of the take a look at.

2. The speculation of a number of intelligences-a unhealthy idea Spearman’s ‘g’ idea is the other of the speculation of a number of intelligences. The speculation of a number of intelligence is an interesting one as a result of it offers some room for everybody to have their very own distinctive strengths in ‘intelligence’. However as we’ve got seen it seems that our cognitive strengths and weaknesses are greatest defined by how a lot effort and time is we’ve got invested into specific expertise or kinds of data. If I take up a technical commerce and turn out to be good at it, and discover that I’m combating studying fiction, this does not essentially imply that I’ve a particular ‘intelligence’ for technical pondering and haven’t any means for studying or language. The very fact I battle with fiction is best defined by the truth that I’ve invested my intelligence into build up this specific sort of experience and thus see extra of a return on that funding in technical modes of cognition. If I had spent as a lot time studying fiction as I’ve making use of myself to technical issues, chances are high I would be good at that.

3. The speculation of fluid intelligence (gF) and crystallized intelligence (gC)–another good idea

This idea builds on the overall intelligence idea, and was initially proposed by the psychologist Raymond Cattell again in 1943. It holds that g is meaningful–that we every have a special common intelligence level– however contributing to g are two several types of intelligence: fluid intelligence (gF) and crystallized intelligence (gC ). Fluid g is the power to purpose and drawback clear up with novel duties or in unfamiliar contexts (measured reasoning duties), whereas crystallized g is outlined as acquired data and is measured utilizing exams of common data, arithmetic, and vocabulary. This twin approach of understanding intelligence permits for data that you’ve got constructed up particularly areas to compensate for limitations in general reasoning and drawback fixing ability– our ‘uncooked intelligence’. You could succeed as a result of data a couple of job or area (crystallized g), or as a result of sheer psychological ‘horsepower’ (fluid g).

The place the concept of ‘a number of intelligences’ is sensible: as crystallized intelligence that we spend money on

Our crystallized intelligence permits for ‘a number of intelligences’. You may have a excessive stage of crystallized intelligence in graphic design, for instance, whereas having solely a median stage of fluid intelligence. However you’ll solely be capable of use your crystallized intelligence for graphic design in conditions through which you’re acquainted and have constructed up experience. Except you’ve gotten a excessive stage of fluid intelligence if you find yourself confronted with an unfamiliar drawback in graphic design–something ‘out of context’, requiring some troublesome figuring out-then you’re more likely to have difficulties. On the flip facet, when you’ve got a excessive stage of fluid intelligence, it can take you much less time to select up graphic design (or no matter) expertise as you study your primary talent set. Your studying might be extra environment friendly, and you can see it simpler. Basically, the extra fluid intelligence you’ve gotten the extra it is possible for you to to ‘make investments’ it into crystallized intelligence expertise and knowledge–the extra ‘a number of intelligences’ it is possible for you to to develop in the event you so want. Within the context of labor, the extra gF you’ve gotten the extra shortly and effectively you could be educated. One examine confirmed that it took folks within the 110 to 130 IQ vary about 1 to 2 years to meet up with the super-charged efficiency of these with IQs of 130+ who had solely Three months’ expertise on the job.


Taking a look at all of the proof, each the overall intelligence (g) idea, and the fluid intelligence (gF) and crystallized intelligence (gC) are effectively supported and helpful in explaining how we differ in our cognitive skills. For my part, the fluid and crystallized idea is the extra insightful and helpful. It helps me perceive intelligence-and how we are able to enhance it-better. For example, analysis reveals that you are able to do a selected sort of ‘working reminiscence’ mind coaching to extend your fluid intelligence stage substantially–but this coaching doesn’t instantly have an effect on your crystallized intelligence.
