There have been many significant upgrades to computer hardware technology but one that is often overlook is the increased speed you can now get buy purchasing a Sata 3 or Sata 6Gb/s hard drive. It took some time after the full 3.0 standard release May 27, 2009, but HDD are now very affordable and most new motherboards come with Sata 3 compatibility.
Sata 2.0 vs. Sata 3.0
We all know that the increased standard means higher speeds, but just how much? The maximum achievable speed for Sata 2.0 was 300 MB/s, only capable with a solid state drive. For Sata 3.0 we already have seen speeds in excess of 500MB/s with Intel’s 510 series. For HDD the speeds is noticeable during burst periods but HDD do not, in general, exceed the 300MB/s Sata 2.0 protocol. Still, ThinkComputers.org as well as many other product testers have proven that Sata 3.0 HDD are indeed faster.
Hard Drives are Still Crucial for Storage
Seagate recently stated that solid state drives won’t replace hard disk drives for quite a while because the supply of NAND Flash memory is simply too small for all the micro devices that use it. Because the price of SSD will remain high with the low supply expect to be using conventional hard disk drives for quite a while.
