Im thinking of setting up a SSD based raid 0 for my computer. The main reason i want this is for the speed. One thing that has constantly come up is the reliability, but every thread, or video are normally about the HDD, so I'm wondering if anyone out there knows the chances of a 4 way ssd in raid 0 are of failing. Also, if one did fail, does that mean they all are broken?

In RAID0, if one fails you will lose all data. Also, trim does not work in RAID0 configuration. You will have to manually perform the trim function.

What is trim? but also what are the chances of raid 0 failing?

It is hard to say about the chances. From one to two ssd's you double your chances and so on.

Trim function for ssd's is a function that resets deleted bits so they can be written to faster. When you delete data or programs the space that was deleted will be reset or zero'd out. Both Win7 and 8 have this funtion but it does not work with RAID0. So after a while if you do not manually optimize the ssd, it will start to slow down and maybe have problems too.

You are probably better off getting a large capacity ssd instead of smaller ssd's and RAID them.

EDIT:
Lot's of users are finding that trim is not working on ssd's that are used for storage too. Seems that an OC must be on the ssd's.

i would be using mac osx in this case, so what is the deal with raid 0 on that?

With a RAID 0, if one drive dies, or whatever RAID cocntroller (hardware or software) dies....the entire array is toast. You cannot get anything back out of it.

Add to that the minimal if any performance gain you get from SSD's in a RAID 0. They are already fast. You are adding zero performance.

Chances of fail of 4 SSD's in a RAID 0? Many times the rate of a single drive.
