TRIM is a way for SSDs to mark data blocks as being not in use. December 3, '14 Comments  Posted in Win7|Win8 Sponsored By There has been a LOT of confusion around Windows, SSDs (hard drives), and whether or not they are getting automatically defragmented But due to SSD's nature, how do you keep your SSD in top-notch to keep up that high level of performance?

Writing to empty blocks on an SSD is faster that writing to blocks in use as those need to be erased before writing to them again. Application performance is also tested on a variety of drives. I can't remember if I tested noop. Although I suppose burst is several seconds long, so it does reflect on the drives' skill in reading data before it's needed. (Something SSDs don't really have to do, so no check over here
So while I think Win7 looks purty, I think I'll just sit this one out, thanks. It seems my anecdotal evidence has cancelled yours out. And here are a list of good ones that definitely worth your attention. 5 free tools to analyze your SSD CrystalDiskInfo is a hard drive utility that checks your hard drive's read/write speed, There’s no bug here, sorry. - Me in the Past I dug deeper and talked to developers on the Windows storage team and this post is written in conjunction with them
It feels quicker, due to this fact, and as such, the entire computing experience on Windows 7 is much more enjoyable. MS was never good at communication. All volumes are processed by the same ScheduledDefrag task triggered by Automatic Maintenance (AM), and only under this condition SSD defrag may occur naturally.

But the original post was much appreciated, despite the fact that it wound up that noisy little guy. Full stop. However, the problem never felt completely resolved, and in the minds of most users, the damage was done. navigate here And Windows 10 treats SSD drives even better.

It's easy, just takes time. Here, I totally felt the opposite. Ok, they just ensure the SSD defrag period is less than 28 days.But there's no word on the fragmentation level (you haven't discussed or disclosed it), so now it sounds like his comment is here Not some unnecessary housekeeping task that seem Microsoft developer or marketing chum decided to impose on me.
It can be useful for performing the regular "health test" for your drive and predicting its degradation, so you will be able to prevent data loss and backup your files before I've heard good things about CFS.An ideal SSD scheduler would need to perform read/write grouping, but only within the SSD blocks (with a read block and a write block being different If you disable defragmentation completely, you are taking a risk that your filesystem metadata could reach maximum fragmentation and get you potentially in trouble. With Windows 7 and an SSD, should I turn the disk defragmenter service back ON (I disabled it when I first installed the drive 3 yrs ago)?
