So,I saw some Gigabyte motherboards with z77 or z75 chipset which have builtin raid controller. As there are builtin raid controller i assure they need driver in os to function. So my question is, Are these builtin raid controllers supported in mac ?

If supported i'm planning to buy one motherboard and two ocz ssd and make raid 0 with them. is that a good idea ?

Thats sad news :(
What is the condition of software raid in hackintos then ? Can i install osx on a raid 0 (software raid) ? I see software raid option available in Disk Utility.

You can, but on SSD's it is not worth the effort. Can you tell the difference between a nanosecond and a microsecond?
RAID boot drives are a PITA. I never recommend a boot drive in RAID array. Use RAID for storage security - not in an attempt to speed your boot drive.

When it comes to SSDs I really don't see the point of RAID 0. RAID 1 maybe, for security, but you might as well just get a TM backup going instead.

The motherboard "raid" on consumer level motherboards is just a software raid anyway. That's why it doesn't work under OSX, there's no drivers for it.

Basically, only some server motherboards have any sort of a real raid controller.

The big thing an SSD does that typically gets you the most dramatic improvement in performance and responsiveness, is not the Mb/sec throughput, it's the drastic reduction in access times. Since there's no need to wait for the disk to rotate around to the piece of data and the are no read/write heads that have to move into position, it's essentially zero access time. So there's just a lot less waiting on the part of the computer when it has to read something from your SSD than with an HDD.

The next big thing is going to be the rise of PCIe based SSDs, since they aren't limited by an interface designed to work with a mechanical disk and PCIe is a very low latency direct connection to the CPU.

but after all, if a single SSD vs raid-0 two ssd with give better performance isn't it ? Actually i never done any raid experiment so willing to do some.


Thank you very much ggeorge for your detailed explanation :) Highly appreciated :)

Because of how SSDs work, write speeds are usually significantly lower than the read speeds. Raid 0 does help with that, since you will be writing to both drives to a certain extent. A lot of the PCIe SSDs actually use a raid 0 set up, which is a lot safer than with mechanical drives, due to the lack of physical parts to break.

Mind you it doesn't change the fact that if something happens to one of the drives you will loose what is on both of them...
