Yes. Any kind of RAID array.
Yes. Any kind of RAID array.
Thanks Kappy.
I use ssd1 as the boot drive. I want to add another same size ssd2 to create a striped raid set.
The question is, can I use this software raid set as boot drive ?
Thanks for any help.

Barefeats was looking at two 6G but you still have very limited bandwidth with Mac Pro's controller not even offering 250MB/sec per SATA port, they are not independent, they are not "per port" at all like the literature mentions. They share a single controller and offer only 600MB/sec for all four drive bays.
The maximum average transfer speeds of internal SATA RAID 0 sets are limited on the both the 2009 'Nehalem' Mac Pro and previous Mac Pros. This may be due to the fact that the I/O hub has only 1000MB/s to disribute among all I/O devices including USB and FireWire.

If you are planning to boot from a RAID 0 array, you may not see any better performance than you would booting from a single SSD. That's RAID set can't do any more transactions per second than a single SSD.

Better to spend your money on one good larger SSD than two.
Thanks for your help.

The built-in RAID software in Disk Utility works fine. Be aware, though, that creating the array will erase both drives, so be sure you make a full backup (preferably a bootable backup) before proceeding.
ssd raid... possible?
