I got 2 retired but rarely used OCZ vertex 2, 50gb and I'm thinking about using it in my machine as a boot drive, upgrading from 2 Seagate 7200.7 PATA that I was RAID 0 with (2 x 120 gb). I know OCZ is unreliable but with mirror I think I can take the chance. With the AMD motherboard raid (MSI 880G-E45) and windows 7, I will probably have no AHCI support and therefore no trim support. Would alignment be an issue if I just clone the existing partition from a HDD? So far the only thing I will be buying would be some molex to sata power cables and the rest is what I already have, so it is not really a lot of money or time spent anyways.
