Ata Versus Sata? Which one works the best?
Hard Drives: ATA compared to SATA
The efficiency of pcs has been consistently increasing as quicker processor chips, memory, and video cards are consistently being developed. The one key component that is often ignored when looking at improving the efficiency of a pc is the difficult generate. Hard generate producers have been constantly changing the standard difficult generate used in contemporary pcs for the last 25 decades, and the last few decades have seen some interesting developments from quicker spindle prices of rate, bigger caches, better stability, and increased information transmitting prices of rate.
The generate kind used most in consumer quality computers is the satisfying ATA kind generate (commonly known as an IDE drive). The ATA conventional returns again to 1986 and is based on a 16-bit similar interface has gone through many evolutions since its release to boost the rate and size of the pushes that it can assist. The newest conventional is ATA-7 (first presented in 2001 by the T13 Technological Panel (the group responsible for the ATA standard)) which facilitates bandwidth prices up to 133MB/sec. This is anticipated to be the last update for the similar ATA conventional.
As long ago as 2000 it was seen that the similar ATA conventional was maxing out its restrictions as to what it could handle. With information prices reaching the 133MB/sec mark on a similar cable, you are welcoming all sorts of problems because of indication moment, EMI (electromagnetic interference) and other information stability issues; thus industry management got together and came up with a new conventional known as Sequential ATA (SATA). SATA has only been around a few decades but is intended to become “the standard” due to several advantages to being resolved in this Technological Tip.
The two technological innovation that we will be looking at are:
ATA (Advanced Technological innovation Attachment) – a 16-bit similar interface used for managing pc pushes. Introduced in 1986, it has gone through many evolutions in the last 18+ decades, with the newest edition being known as ATA-7. Wherever an item is referred to as being an ATA system, it is generally a Parallel ATA system. ATA devices are also generally known as IDE, EIDE, Ultra-ATA, Ultra-DMA, ATAPI, PATA, etc. (each of these shortened forms actually does refer to very specific items, but are usually interchanged)
SATA (Serial Innovative Technological innovation Attachment) – 1-bit serial progress of the Parallel ATA actual storage interface.
Basic Functions & Connections
SATA pushes are super simple to differentiate from their ATA relatives by the different information and energy relationships discovered on the returning of the pushes. A side-by-side comparison of the two connections can be seen in this PDF from Maxtor, and the following includes much difference…
Standard ATA pushes, such as this 200GB European Electronic design, have somewhat heavy, 2 ” extensive ribbons cable with 40-pin information relationships and receive the 5V necessary to energy them from the familiar 4-pin relationship. The primary information cables for these pushes have looked the same for decades. A modify was made with the improvement the ATA-5 conventional to better boost the indication quality by looking into creating an 80 cable wire used on the 40-pin plug (these are usually known as 40-pin/80-wire cables). To improve air circulation within the pc some producers turned to basically foldable over the ribbons cable and tape it into that position. Another recent actual modify also came with the coming of curved cables. The efficiency of the curved cables is equal to that of the flat ribbons, but many prefer the improved program air flow provided, ease of cable management, and chilly appearance that come with them.
SATA pushes, such as this 120GB European Electronic design, have a half inches wide extensive, 7 “blade and beam” information relationship, which results in a much slimmer and easier to manage information cable. These cables take the comfort of the ATA curved cables to the next level by being even smaller, more versatile and capable of being longer without fear of information loss. SATA cables have an optimum length of 1 gauge (39.37 inches), which is much higher than the recommended 18 inches wide cable for ATA pushes. The reduced impact of SATA information relationships releases space on motherboards, potentially enabling for more practical templates and room for more onboard features!
A 15-pin energy relationship provides the 250mV of the necessary energy to SATA pushes. 15-pins for a SATA system seems like it would require a much bigger energy cable than a 4-pin ATA system, but in reality, the two energy connections are just about the same size. For the moment, many SATA pushes are also coming with a heritage 4-pin energy plug for comfort.
Many contemporary motherboards, such as this Chaintech motherboard, come with SATA generate relationships on board (many also such as the ATA connections as well for heritage generate compatibility), and new energy supplies, such as this Super X-Connect, generally function a few of the necessary 15-pin energy relationships, creating it user friendly these pushes on new techniques. Older techniques can simply be improved to returning up SATA pushes by use of plugs, such as this PCI port SATA operator and this 4-pin to 15-pin SATA energy adaptor.
Optical pushes are also becoming easier obtainable with SATA relationships. Drives such as the Plextor PX-712SA take advantage of the new interface, although the efficiency will not be any higher than a similar visual generate with an ATA relationship.
In addition to being more practical to install and illustrating less energy, SATA pushes have efficiency advantages that really set them apart from ATA pushes.
The most interesting efficiency function of SATA is the highest possible data transfer usage possible. As we have mentioned, the progress of ATA pushes has seen the bandwidth rate reach its highest possible at 133 MB/second, where the present SATA conventional provides information exchanges of up to 150 MB/second. The efficiency improves of SATA over ATA can currently be anticipated to be up to 5% (according to Seagate), but developments in SATA technology will surely develop that.
The upcoming of SATA holds excellent achievements for those wanting even more rate, as pushes with 300 MB/second exchange prices (SATA II) will be obtainable in 2005, and by 2008 prices of a rate of up to 600 MB/second to expect. Those prices of rate are amazing and are difficult to imagine at this point.
Another efficiency advantage discovered on SATA pushes is their built-in hot-swap abilities. SATA pushes can be brought on and off-line without ending down the pc, providing a serious advantage to those who can’t afford recovery time, or who want to move pushes in and out of operation quickly. The higher number of cables in the energy relationship is partly described by this, as six of the fifteen cables focus on enabling the hot-swap function.
Comparing ATA pushes to SATA pushes can be challenging given all of the factors, but in general, it is the case that SATA pushes will still cost just a bit more than a similar ATA generate. The gap is ending rapidly though, and as SATA pushes gain in popularity and accessibility a unique move in prices to expect. Considering the advantages of SATA over ATA, the potential difference of a few dollars can simply be validated when considering an update. Computer Nerds currently has a limited selection of SATA pushes, but several technical sites, such as The Technological Area and The Technological Living room, offer real-time cost books to see how similar pushes compare.
The present SATA conventional provides significant advantages over ATA in terms of comfort, energy consumption and, most significantly, efficiency. What is important ATA has going for it right now is history, as it has reigned supreme for such a long time that it will not likely vanish in the near future. The way forward for SATA will be even more interesting as rate improves will help difficult generate development keep speed with other key program elements.
