I have a new single (non-raid) Crucial C300 SSD on am ASUS Sabertooth MB with Sata III Marvel and Sata II Intell. I want to use the TRIM function in Windows 7. Should I install the Marvell or Windows driver and use on Sata III? Or, should I use this on the Intell? Also, if I am not using the RAID do I need the JS Micron Driver? Any suggestions woudl be appreciated. Thanks.
In November I built 4 systems with that Sabretooth/C300 combo and I can verify both the Marvell SataIII and Intel SataII both support Trim and are fully functional without special drivers other than what Windows 7 natively supports. Both ports are exceptionally fast, but several different benchmarks showed the Marvell being about %20 faster for the software we are running.
At that time, the Trim commands were not being passed through the raid interface correctly. The drivers for the raid controllers may have been updated to fix that, but since you are in a non-raid scenario, you're not affected. You dont need to install the JS Micron drivers if you aren't doing a raid setup.
FWIW, when upgrade time comes again in a year or two and you have bought a new system, that Sabretooth motherboard is fully supported by ESXi, so you can save your old mobo and make your own Virtual Machine server. Congrats on picking Asus, i'll never use another brand again ;-)
