HELP GETTING GARBAGE/C TO WORK

[hash70]

hi i have 3xcrucial c300 in raid0,read/write speed are the same as the first day i put them in but the 4k speed is way down giving me a score of 950 when i used to get 1600,i read that if i left my pc at the log in screen g/c would kick in so i left it there 2 nights in a row for a total of 20 hours then ran the ssd benchmark again to find i got a even lower score,im really thinkin of gettin rid of raid0 and jst use 1 for the OS and then use steam mover to move my games about on the other 2 ssd?

GC might not work properly without TRIM (Controller cannot see empty blocks actually as empty). Does your RAID config support TRIM?

Sorry for hijacking this thread- does any RAID support TRIM?

Afaik some controllers do, yes.

Indeed. I suspect TRIM is not running and this could be the problem. Check if TRIM is running or not ;

Open command prompt as an elevated user (run as admin).
Type the following: fsutil behavior query disabledeletenotify
If the result is '0' TRIM is enabled.

trim is enabled,jst checked,any idea anyone?

not all SSD have idle time garbage collection. At least intel's don't. I don't know about crucial, i assumed they did.

Also you shouldn't really bench SSD. Apparently it degrades performance if you do too often and don't give it time to do the idle GC(assuming it uses it).

by the way just becasue trim says it's enabled in the CMD it doesn't mean it is passing the command on to RAID set. afaik no SSD in a raid set can use TRIM...could be wrong though, i'd ask crucial.

I'm currently in a similar situation myself with intel SSD's. Don't know whether to sell them, or use them stand alone in AHCI with one windows, one games, etc...All i know is that Intel said they don't recommend raid for SSD's and that in real world desktop use it's pretty much pointless and won't really be noticed and can even worsen performance at times. Personally i'm more into real world use than benchmarks. I'm sure people can wait 2 or 3 seconds more for windows to load or a game level or whatever...just my opinion

+1. From what I have seen bench wise, Raid0 actually slows down Performance of everyday tasks, boot, app launch, game load etc. It only really seems to help when moving around larger file sizes. The more drives you add in raid seems to slow it more and more also. Myself I think, buy the fastest single drive you can afford that has the space you need. To some It may look like the sata 3 bandwidth may be a limiting factor but the truth of it is, that in general operation new sata 3 drives aren't even maxing the sata2 bus and you could even perhaps argue the same for the sata1 standard. Only for large read/wrights do these drives really come into there spec and myself I have no need for large read/wrights often enough on my boot drives to really even consider that a concern.
