SEAGATE BARRACUDA 7200.9 SATA DRIVER DOWNLOAD - As with any Seagate hard drive, this drive is made with quality in mind. Good product This hard.
Drive Models First off before we dive into this review, we want to take a look at the Seagate strategy behind the new 7200.9 series. Seagate with the new line of drives intends to replace its current desktop line with one model from the ground up. With the 7200.8, there were only certain models available; sizes below 120GB would have required you to go back to the 7200.7 generations, not this time around though. The 7200.9 series has models with the following specifications, 40, 80, 120, 160, 200, 250, 300, 400 and 500GB models respectively. This is truly the first drive to support all the HDD requirements from base system all the way to high end storage capacity of the lechers like me out there. What makes this line up unique are the different specifications that accompany each drive. For example, there are drives with 2MB cache, 8MB cache and 16MB caches depending on what version and sizes are chosen.
The 40GB drives are the base model but mostly we won't see these on the retail market, OEM and system integrators will use these. This drive runs at 7200RPM with a single 40GB platter and a single read/write head. This dive uses the lowest amount of cache being 2MB and is available in PATA or SATA configuration. The 80, 120 and 160GB models use the same setup only you can get them in either a 2MB cache or 8MB cache model with SATA or PATA connectors.
The 200 and 250GB models are set with an 8MB cache only with the 300, 400 and 500MB models using the full 16MB cache for the ultimate performance. Compatibility and Specifications The Seagate 7200.9 is the first to market desktop hard disk drives that are SATA 2.5 spec compliant. This has become quite confusing, in fact we even was wondering what was the deal between SATA-II and the new SATA 2.5 specifications. In an attempt to try and remove some of the confusion, we are going to try and best explain the SATA-II and SATA 2.5 specs. Myths and Facts First and foremost, SATA-II is not actually a standard, but was the name of the first group of companies that came up with the additional requirements in order to become compliant with the latest high speed hard drive technologies.

Though this hasn't actually stopped quite a few hard disks to come out claiming SATA-II support, although technically in order to get SATA-II compliant you only need to support two of the additional SATA extensions created by the now SATA International Organisation or known as SATA-IO. The new extensions are 3gbps transfer rate, Staggered Spin up, Speed Spectrum Clocking, Hot Plug, e.SATA, Hot Swap Native Command Queuing and click connect. SATA 2.5 is actually a specification created by the SATA-IO. In order to obtain SATA 2.5 quality you must support ALL of the SATA-II extensions in the one drive, which we are pleased to say that the new Seagate Barracuda 7200.9 series does as well as automatic step down. Another myth is that SATA 3G will dramatically increase the HDD speed, this is somewhat wrong.
