AHCI and TRIM on PHOENIX

[kamalmawa]

Hi guys. Just bought a G.Skill Phoenix 120GB Drive and first I installed on IDE mode. After realizing wasn't getting enough performance on IDE mode I switched to AHCI mode as many people says it boost the performance. Then started to getting close to as it says on G.Skill product page but when it's with the AMD AHCI driver also windows boots much quicker. Then I saw on some website that TRIM command won't work with AMD AHCI driver & it's better to switch to Microsoft generic driver. Then I un-installed the AMD AHCI from Catalyst Control Center and now running on generic Microsoft driver came with the Windows 7. But the performence isn't that good as it as on AMD AHCI driver. What should I do ? loose the TRIM by installing AMD driver or keep on generic driver ?

Also what is the different between PHOENIX Pro & PHOENIX versions ? any performance differences ?

My motherboard has both JMicron & AMD chipset SATA controllers . SSD plugged in to AMD one

here is the results with MS Generic driver as you can see writing speed isn't that good as it says on G.Skill page http://www.gskill.com/products.php?index=285



Thanks in advance.

Hi kamalmawa,
With TRIM work you could prevent the performance slowdown of ongoing usage and i think that you would not feel the slower performance in the real life with windows generic AHCI driver compared to AMD AHCI driver. So Before AMD driver support TRIM command, the better choice is use Microsoft generic driver.
Compare to Phoenix, Phoenix Pro has higher 4KB random write IOPS but you may not aware the difference in your application. Usually some server application has such condition could reveal the advantage.

Is that mean desktop users won't see much different between those two ?
Thank you very much for your opinion on this. Needed to hear this from someone who actually have more experience with SSDs Hope AMD releases proper driver soon. Till then I'm gonna stick to the MS driver as you said..
