post #1 of 27
Thread Starter 
I have a adata s596 turbo 64gb and after 2months it dropped from 120mb write to 60mb write and the read was still at 250mb, i did a Secure erase from within linux and now its at 120 and 260, factory spec is 130 and 240 lol did i do good? why did it degrade so fast, trim is on.

Did you run the maintenance programs once a week? You may need to read up on how TRIM works. The more stuff that you delete, the more clogged up the drive gets. The maintenance programs get rid of the deleted blocks written into the drive thus speeding up the drive.

yes, im curious about this myself. I just got my c300 installed yesterday. I though all you needed was to have trim enabled. What else can I do to maintain good performance and longivity of my ssd?

That is why I asked how did you know. It is a common mistake when people think that TRIM is enabled just by looking at fsutil=0 or 3rd party programs. All they show is whether TRIM is enabled in Windows 7. There is no easy way if it is enabled on the drive. Only by tedious testing. SSD Life tells (and I specifically checked) if the TRIM is "supported" by the drive, not if it is working and the drive receives TRIM commands from the OS.

Could you please post a screenshot from AS SSD benchmark tool? It might be due to drivers that are installed that TRIM is not working. Also what port is SSD connected to?

If the drive supports TRIM and if TRIM is enabled in Windows 7, then TRIM is working.

If the drive doesn't support TRIM, then TRIM isn't working even if it's enabled in Windows 7.

The drive might support TRIM (as most drives do) and it might be enabled in Windows but it doesn't necessarily mean that the controller or the driver passes the TRIM commands from the OS to the drive. Like it is the case with Marvell controllers.

However, as I can see, renji1337 has got P67 board with both SATA 3GB/s and SATA 6GB/s Intel controllers. I have little experience with those. So I am not sure what could cause performance degradation. SATA 3GB/s will work for sure with latest RST drivers.

Oh ha, I was forgetting about the fact that it also depends on which SATA ports the drive is connected to.
