Raid 0 SSD's - any point?

Raid 0 doesn't support trim so you wont be destroying it you just wont be using it, but the ocz drives have carbage collection which works with raid 0 and is pretty much the same as trim
 
Here's 2 x Vertex 2E 60GB in Raid O. Even if the arrays performance degrade by 50% (Which I doubt), the speed will still be equal to a single Vertex 2 120 GB.

Got another question to ask, I will go for raid 0 for a year, but if I do change my mind and go back to single SSD again, do I need to go back to secure erase (to get the trim and performance back as a manufacturing standard) ?

Can I use windows back up ? (system image) to back up Raid0 just in case if Raid0 data had loss or failure in future to get all the re-image restored back again.

I might be wrong but arnt the revodrives basically 2 SSDs welded together and running in a raid? I was under the impression that this was one of the reasons there so badass.
 
It's still only a single SATA connection though, so you don't get the massive read/write gains when doing RAID yourself.

I suspect Windows 7's backup will support backing up from RAID. You just need to make sure you recreate the RAID when you come to restore.

They use a completely different interface. They are PCI-E based and not limited by SATA transfer speeds.

I know, thats the other reason there so badass :) Im sure i read somewhere that its multiple SDDs stuck together in its own raid tho.

I just been research...that 2 x SSD's in Raid 0 will destroying IMPORTANT Trim support (if ever go back to single SSD in future) mean if the 2 x SSD's already in Raid0 and later on, change mind want to go back as a single SSD's and the Trim support will be gone!

Very confused about Trim is very important part (as raid0 doesn't support any Trim)

Your sources are wrong. No functionality is "destroyed". When in RAID any TRIM commands just won't be passed through, If you decide to go back to a single disk setup the TRIM commands will work fine.

It's really not such a big deal anyway, the speed boost from RAID more than makes up for the performance loss of the individual drives not being in perfect condition. On decent SSD's performance when "dirty" is still around 90% that of a fresh drive.
 
I got a lovely 2 x OCZ Vertex 2 SSD in Raid 0 and the performance is crazy lightning speed in windows 7 score 7.9 in windows index score and everything is totally instant open straight away, no more delay or waiting.

These look amazing over 500Mb/s in both read & write.

nice one thats the same speed as what im getting and ive had mine for 3 months now so garbage collection must be working
 
I had done Windows 7 System Image back up to my hard disk (64GB SSD old one) and then wipe out both SSD 120gb x 2 in raid 0 and try to restore it back with windows system image restore and it does work !!! Got my windows 7 in raid 0 back as it was before (useful if raid 0 failure in later stages) as I might getting 240gb ocz SSD for storage of back up, video's, music's, photo's doc's and game's saved. I am pleased as it work out pretty well. I had double check speed of write & read after restored using system image and it does work over 540mb/s in both read & write. Excellent windows 7 backup. :)

Somethings not right on your set-up bulldog147. Compare my small read/write speed specially the 4k and you will see a big difference.

Maybe it to do when a solid state drive is present, Windows 7 will disable disk defragmentation, Superfetch, ReadyBoost, as well as boot and application launch prefetching not set up proper ? How can I check all these setting to ensure it correct fix in windows 7 ?
 
Intel Rapid Storage Technology "write-back cache" was disabled by default as I had now turn this to enabled and look at the results here:


Surely that can't be right (a write speed of more than 600mb/s but poor read speed of 400mb/s ???)


And again write speed is better than read speed (something not right here ???)
 
Where did you enable write back caching, in Intel storage application or in Device manager?

You should disable it from Device manager then restart then enable it again then restart.
