I had an old netbook with an SSD. A lot of folk noticed that the performance of the disk got slower over time. Surprisingly, defragging the drive actually improved the performance -- but IIRC it was a side effect of the process, not directly anything to do with fragmentation.
I don't quite remember what the issue was, but there was a good anandtech article about it: http://www.anandtech.com/show/2738/8 http://www.anandtech.com/show/2738/8
Fairly certain modern SSDs are not affected, in any case.
- acqq 15y agoArticle says: (Windows 7) "the OS knows it’s a SSD and turns off features like defrag" So you claim to see improvement from something turned off by the OS? How?
- starwed 15y agoErr, this was several years ago, and I was relaying what other folk with the same device (ASUS 901) reported, not my personal experience. (And not only was this was before the release of Windows 7, it actually came with some version of Xandros installed...)
- ScythedBlade 15y agoAhh, do you know why? TRIM support isn't being used. When you're defragmenting, all you're doing is forcing the drive to write a lot, which itself essentially is a crazy way to fix it without TRIM command, but it works. On the other hand, you're doing a lot more write cycles than what TRIM or garbage collection would normally do.
