Hayder_Master · Nov 10, 2010, 06:20 AM

hi guys, i have friend in U.S and he take my advice to built a PC
gigabyte x58a-ud5,i7 950,gskill 3x2g,2xgtx 460, and crucial SSD 64G C300
so now he set it in sata 3 6gbs and suddenly feel there is some drop in SSD speed, it should be over 300mb/s max read speed on sata3 and over 200mb/s in sata2 now max read is about 140mb/s in sata 3

I know very little about SSD drives and only just installed my first one a few days ago.

I found that any setting other than AHCI in bios, results in serioulsy below par performance.

Hayder_Master · Nov 10, 2010, 07:53 PM

ok i forget that, sure i tell him about that cuz i use SSD too it's on AHCI

Hayder_Master · Nov 11, 2010, 04:44 AM

guys anyone

wahdangun · Nov 11, 2010, 04:53 AM

do your SSD support trim?

n-ster · Nov 11, 2010, 05:39 AM

ofc the C300 has TRIM

Chevalr1c · Nov 11, 2010, 05:45 AM

TRIM will be disabled once the SSDs run in RAID mode AFAIK. Though RAID is not being used here, is it?

n-ster · Nov 11, 2010, 05:48 AM

ofc there is no RAID...

Have you tried a Windows reinstall?

Solaris17 · Nov 11, 2010, 05:52 AM

turn off defragmentation. you dont defrag SDD's. Win 7 has defrag in the background.

RejZoR · Nov 11, 2010, 09:14 AM

Which gets disabled when OS detects SSD drive...

sorry didn't get it, please more details

Tyrael · Nov 11, 2010, 01:11 PM

Have you tried updating your motherboard? New Bios will stabilize your SSD drive performance...

EastCoasthandle · Nov 11, 2010, 01:21 PM

Tell him to contact the manufacture and explain to them the problem. They should have some sort of solution.

n-ster · Nov 11, 2010, 06:34 PM

As I said, try to reinstall the OS
