Windows 7 improvements for SSDs detailed

Posted on Thursday, May 07 2009 @ 00:00:28 CEST by

A new blog post appeared on the Engineering Windows 7 blog, it details several of the optimizations Microsoft has made in Windows 7 to improve support of solid state disks. There's support for the Trim command and several changes to the default behavior of the drive. You can check it out over here, below is a brief snip:
Windows 7 will disable disk defragmentation on SSD system drives. Because SSDs perform extremely well on random read operations, defragmenting files isn’t helpful enough to warrant the added disk writing defragmentation produces. The FAQ section below has some additional details.

Be default, Windows 7 will disable Superfetch, ReadyBoost, as well as boot and application launch prefetching on SSDs with good random read, random write and flush performance. These technologies were all designed to improve performance on traditional HDDs, where random read performance could easily be a major bottleneck. See the FAQ section for more details.

Since SSDs tend to perform at their best when the operating system’s partitions are created with the SSD’s alignment needs in mind, all of the partition-creating tools in Windows 7 place newly created partitions with the appropriate alignment.
