Actually it does not, the driver that you use does not pass the TRIM command through to the drives properly or at all as of yet.

then why does trim say its enabled then? and it wouldnt matter if it was enabled or not the m4's have garbage collection anyway.

Well, i've been running Raid 0 SSD for over a year, and I have yet to have any real perf drop (maybe 10-20mb/s drop from over 550).

Anyway, looks like bad drivers or something. From what i've seen, the whole "no trim in raid" thing isnt much of an issue.

Just because it says TRIM is enabled does not mean it is able to run it. There's no controller on the market (to my knowledge) that supports Raid 0 trim yet. Garbage collection is not as good as TRIM, but its a heck of a lot better than nothing like this guy's SSDs.

Your SSDs also have garbage collection, so it's no surprise your performance isn't dropping as fast (or as major) as this guys.

well basically windows 8 has better drivers for raid, I read somewhere that trim was indeed working on 2 ssd's in raid0. (im using windows 8)

I sold one of them after a year because I was reformatting and secure erasing every 3 months or so before writes were noticeably terrible. It all depends on what the user is doing, some programs can really cause them to slow down faster.

Yeah, but what you were sayin earlier is totally different than what you are sayin now. What you were basically saying earlier is that all ssd should not be raided

And this particular SSD doesn't even have trim support, so why not RAID it?

TRIM just speeds up garbage collection bro, it just basically tells the controller "this file just got deleted, do the garbage collection nao!"

But, the X25-V has built-in garbage-collection.

TRIM simply does not work in RAID for SSDs in an array as of yet. If the SATA mode is set to RAID and the SSD is not part of a RAID array then that is when TRIM does work, but not when two SSDs are put in RAID together.

Wait what? I guess with this many SSDs on the market i'm starting to get them confused. Could of swore the X25-V had TRIM but lacked any type of garbage collection when in RAID. It's getting late here and I got up way too early, maybe it's time for bed. I stand corrected.

I will say that, in my opinion, I still feel raiding SSDs is near pointless. There are no real world benefits unless you are doing massive file transfers and need the extra sustained speed. Most SSDs now are offering the same price per gig ratio on all their models, and it's just better to grab a single 256GB SSD than 2x 128GB when both models support TRIM. Strictly my opinion ofc.

Tired or not, I'm 100% sure you do not having working RAID 0 and TRIM. Windows 8 or not. wink.gif

well, intel supposedly is going to release a driver that enables trim on their drives when in a raid array

technically trim does work with raid, apparently its the storage controllers fault. not windows. windows is perfectly capable of trimming raided ssds. doesn't really matter tho… as long as the ssd has garbage collection there shouldn't be an issue.
