ssd in raid question

post #1 of 4
Thread Starter 
if you raid 0 three ssd's say the 4k random reads are 94,000 iops and the writes are 35000 iops, do those numbers triple or do they stay the same?

No they will be somewhere between 50 and 75% faster than a single drive.

RAID0 doesn't double speeds because there is a lot of overhead to get the data separated.
And with three drives the benefits of RAID0 begin to diminish dramatically. It's still faster than 2, but no where near another 33% faster.

does the size capacity add up and show as a single drive ?

The size of a RAID0 array is equal to the number of drives in the array times the size of the smallest.

A RAID0 array shows (in Windows Explorer/My Computer for example) as a single drive if the array is not partitioned. If you partition the array, each partition will show as a separate drive (just like a single drive would).

Also:
The speed of any array is based on the speed of the slowest drive.
A bootable array can only be created during a Windows install.

What are you trying to do?

Hope that helps.
