Optimize Windows Vista SATA Driver For Best I/O Performance

If you’re affordable to get a high end Home Premium computer or laptop for Windows Vista, always choose to install the OS on a SATA 3.0 hard disk drive for optimum I/O performance.

If possible, totally eliminate IDE hard disk drives as your data file storage too. Windows Vista multimedia performance will be much promising when yours high definition movies, pictures, mp3, etc, are storing on SATA 3.0 hard disk drive.

What is that SATA 3.0 hard disk drive

SATA 3.0 utilize second-generation SATA interface technology for hard disk and optical drive. SATA 3.0 is also known as SATA II or SATA/300.
What is the benefit of using SATA 3.0 hard disk drive

While ATA/133 EIDE hard disk drive transfer data at 133MB per second, SATA 3.0 hard disk drive can achieve double data throughput (data transfer rate) up to 300MB per seconds!

So, is that make sense to use SATA 3.0 by looking at its data transfer rate, the speed of Intel Core 2 Duo and DDR3 SDRAM that come with a high end Home Premium computer system?

Windows Vista comes with built-in support for SATA hard disk, but the SATA driver is not optimized for disk I/O performance!

By default, Windows Vista built-in SATA driver disable the advanced hard disk write caching option that’s used to improve hard disk I/O performance. The reason of this is because a power outrage or hardware failure might corrupting data stored on SATA drive that enabled for Vista advanced write caching.

If you’re using a full-charge battery for laptop or UPS power backup for Desktop and practising periodic backup, you should take a chance to turn on this Vista advanced hard disk write caching!

How to turn on Windows Vista advanced write caching?

1) Type device or devmgmt.msc on the Vista-improved Search dialog box (Start Menu -> Search) to open up Device Manager,

2) Expand the Disk Drives section of the device tree on left panel,

3) Right-click on targeted hard drive to select Properties,

4) Click the Policies tab to get a dialog box similar to this:

5) Click on Optimize For Performance, turn on options of Enable Write Caching On The Disk and Enable Advanced Performance, and click on OK to apply the chances made so far.

Remember the price to pay for enabling Windows Vista advanced write caching! Don’t blame me (but Microsoft) for possible data corruption in the case of power outrage or hardware failure :-)
