I feel that everyone has an OS that is functional for them, some need windows, others prefer Linux, and still more are more proficient in Mac OS... but at the same time it upsets me when corporations "forget" that Windows is NOT the only OS in the world.

Here's why: Defragers move the drive contents around to put files in large contiguous blocks. In doing so, they update the location of the content and the entries in look-up tables (i.e. FAT tables) so the O/S can find the content. However, the old content location is not actually erased, it's just not pointed to by the FAT table. To the drive, the old data is not free space. Now, in the world-of-tomorrow, Defrag utilities will know they are working on an SSD and will use some of the new SATA-8 commands to tell the drive what is free space.

So, in identically configured systems we have not noted any significant difference in background writes. Frankly, today we spend more of our time beating up these drives--trying to break them--than we do looking at background operations. While we've captured a lot of that information, it's oh-so-boring ... Our main interest has been to understand wear implications. Application launch and operation is a lot more interesting and is where SSDs really shine. Hello again, GullLars!

I was actually surprised by your findings. However i have a question: Even if vista alligns the writes better, wich operating system does the most background writes? And how much background write is done in real life desktop enviroments? It would be great to see some estimate numbers of MB/s (or KB/s), write block sizes, IOPS, and how much of this is sequential vs random. Jason Tan, the information you are posting there is partially incorrect, and can be wrong for many SSDs that manage this correctly. This storage blog already has an article on this, reffering to it as garbage collection. This can also be seen as a sub segment of wear-leveling. For more info on this speciffic matter you can google Intels whitepapers for their new drives, as this is one of their main focus points. Great article here.

SSD defragmentation, it seems that while SSDs are immune to deterioration in read speed from file fragmentation, they are quite susceptible to poor write performance from free space (not file) fragmentation. There is some more information available at the Diskeeper Blog which describes their approach towards SSD optimization http://www.diskeeperblog.com/archives/2008/12/hyperfast_is_al.html#comments (Diskeeper are the guys who rule the Windows defrag market) According to them, file defragmentation is not required, as used to be with HDDs, but free space consolidation greatly helps to improve file write performance and drive life. Interesting, no? Reg.
