SSDs are still relatively new tech....pull raid into the equation and there's just so much (little) information out there
Hay Benney boy............First off..........Go for it
Yes,... I would say the slowest drive would be the master speed in theory!........But I've never tried 2 dissimilar SSD units under any Raid
It might work!, but then again
We all know from experience that using drives of a dissimilar nature can cause problem immediately or even weeks down the line.........the biggest problems can be found with drives (Magnetic Platter HDD) with different speeds (RPM)
How this carries through to SSDs is anybody's guess!....All you can do is "suck it and see"
To have the best chance I would put them on the Intel ICH10 controller and just try to load widows after doing the Ctrl+I raid config and set your Bios to ACHI and see if windows will load..... Trim wont work under raid so you'll have to read up on Garbage collection and install/configure accordingly.
Good luck "Jim" on your mission and let us know how it went , ... will be interested myself as to what drives you use and what ATTO benches you can get out of them
if you get this far
