I want use SSD drives in RAID 1 setup. Although performance is important, reliability comes first, so I'm going with Intel drives (either the 320 or 510 series).
This will be installed in a Dell 435T/9000 that has the Intel Matrix Storage ROM on the motherboard. The PC is about 1.5 years old, so it is SATA II, not SATA III.
From what I have read, TRIM is not supported in RAID setups for SSD drives.
Here are my questions:
- What issues will I run into using these SSD drives in RAID 1?
- Is there a substitute for TRIM for RAID 1?
- Does read or write performance decline in RAID 1, if so, by how much?
- Am I better off using Windows 7 software RAID 1 because that would allow TRIM support?

Trim is not normally support by hardware RAID controllers, because it's a command that has to come from the operating system level. But you might have luck with a software raid setup, because then the operating system still sees and knows about the individual disks first, and the raid array second. I wouldn't hold my breath, though, and I don't know how you'd test it.
