Any modern OS is SSD aware and disables defrag by default. Just wanted some opinion of such a setup, and get some good insight as to what to expect.Ĭlick to expand.No, it won't. So far the drive seems fine, like I said it passed smart tools, I supposedly have full drive life left. Yes I have read the DMLuks FAQ, and know of the why they don't like the trim function used. The HP drive has like a 5 year warranty, but realistically I probably will never use it, with how cheap drives are now. As it was so cheap, and wanted a little extra space even though I have a 2TB spinner attached as well. I am a little weary of this drive, it has a jmicron controller, and I recently purchased a new HP M700 MLC 240 gb drive as main drive. I know that I did not trim the device much if at all.Īfter the drive was wiped, and a new distro was installed, I ran smart tools, and drive says the wear level was 100% meaning the drive was like new, and picked up no errors at all. I remember doing some tests, and copied the same files to a USB, and played them on a different computer, and no stuttering happened. that never happened before, it was a sign that soon after, like maybe 3 months I had the corruption problem. I could not recover the drive, had to wipe it clean.Įven before that time I noticed some weird problems, like I had some music files on the drive that when played would have a stutter to them. I had a complete drive data corruption and even the partition table was corrupted. It was setup to use whole drive no extra provision set for what was mentioned above. I am curious if anyone can provide some input how an older sata ssd works under DMLuks, cryptsetup which does not have trim support set by default.įor example, I have a cheap ADATA SP600 MLC 120 gb drive running under Fedora using Luks as the crypt container. So, should I go ahead and use the whole drive? And finally, I've also read that all SSD's come from the factory with about 7% reserved space for wear leveling, and that remains reserved no matter what the end user does. Plus, I keep reading that SSD's now are good for at least 10 years under normal use (I'm using it as my Win10 boot drive), even without heroic measures to extend their lives. That makes it sound like I'll get the benefits of wear leveling without specifically setting up an over-provisioning region, and of course I'd like to have the extra 50 GB if it doesn't shorten the life of the drive. It doesn't matter if it's unpartitioned space or if is is simply unused within the partition." "A key point is that, for most SSDs, and probably all of them from the big manufacturers, ANY UNUSED SPACE is used to manage garbage collection and wear leveling. I just got a Crucial MX500 SSD, and the software that comes with it recommends reserving at least 50GB for "over-provisioning," to provide space for load leveling.īut when I was trying to find out more about it, I found this post from a Micron employee, talking specifically about Crucial SSDs:
