A bit confused over TRIM and SATA III using an SSD.

post #1 of 4
Thread Starter 
Hi. I purchased a Crucial 128GB C300 for $190 and free P&P when it was on sale on Newegg. I am going to put my new PC together Friday. It is my first time doing so. Wish me good luck!

Anyway, I have a ASUS P8P67 Deluxe. Here is the stats from Newegg...

Quote:
Storage Devices

SATA 3Gb/s
4

SATA 6Gb/s
2 x SATA 6.0 Gb/s ports (gray) by P67
2 x SATA 6.0 Gb/s ports (navy blue) by Marvell PCIe 9128

SATA RAID
SATA 6.0 Gb/s ports (gray) and SATA 3.0 Gb/s ports (blue) support RAID 0,1,5,10 by P67
What I'm wondering about it using the TRIM program on a SATA III port. Is it supported on the P67 and no good on the Marvell or are both no good for it?

I suppose if it isn't I'll just use it on SATA II but I was looking foward to the increased speed. I know how a SSD's usage will deteriorate/decline over time without TRIM.

Please inform me. Thanks.

PS: Yes, I've searched! Can't find anything...

I'm not sure if the Marvell chip supports TRIM though I guess it should. However if you use one of the two Intel SATAIII ports (gray) then you will have TRIM & SATA 3. This is the setup I'd recommend as there is no point limiting the performance of the SSD on a SATA2 port.

Use the Intel ports (SATA3), you'll have trim. The Marvell controller is terrible. No one will say if it supports trim. I say NO!

the sandy bridge's native intel sata 6 ports supports trim

however the marvel 9128s does not, at least no one has confirmed it. if you plan to use the c300 as boot drive, make sure it's hooked up on intel's sata 6 and not the marvel sata 6.
