Hi,

I have two SSD installed on a P67 system (Asrock P67 Extreme4). One is the Agility3 120gb connected to slot 0 (sata3) and the other is a Vertex2 120gb connected to slot 1. My problem is that while the system feels quite fast, the benchmarks are really slow compared to the reviews I am reading. I have Intel RST drivers with Windows 7 Home Premium 64x.

AS-SSD Agility3 2.11
Read/Write
Seq: 204,53/136,09
4K:17,97/54,73
4K-64:94,85/132,70
Score:133/201--->407

AS-SSD Vertex2
Read/Write
Seq: 204,07/81,33
4K:17,40/11,52
4K-64:81,81/35,06
Score:120/55--->237

CrystalDiskMark Agility3 2.11
Read/Write
Seq: 206,8/142,9
512K:196,1/143,1
4K:27,11/68,70
4KQD32:75,72/126,1

CrystalDiskMark Vertex2 1.33
Read/Write
Seq: 200,1/78,6
512K:186,4/78,28
4K:19,05/10,54
4KQD32:61,96/28,03

The Agility3 is the new system disk and was transfered with AcronisTrueImage from the Vertex2 disk while Vertex2 now stores my games and was also trasnfered with the Acronis from an older WD disk.
Any ideas?

Thank you
 
a) Are you sure you're using the Intel SATA 3 ports? (see picture below).

b) Did you use AHCI mode when you installed Windows?

If you didn't use AHCI mode then you can fix this.

You need to change SATA Mode from IDE to AHCI in the BIOS.

But you can't just do that otherwise your system won't boot.

You need to apply the fix here first.

So first make the changes in the link, swtich off the PC, swap over to the Intel SATA 3 ports if you haven't already, start the PC and go straight into the BIOS, change the SATA mode for the Intel ports to AHCI, save the changes and the PC will start again and you'll be using AHCI mode.

First of all, thank you for the reply!

Unfortunatelly disks in BIOS are set to AHCI mode and yes I do use the 2 sata3 ports. Intel RST drivers verify this too...The only thing I havent done is a fresh install of Windows which I am not willing to do.
 
I'm not completely au fait with all the ins and outs of SSD's as I don't own one.

Isn't there something about partition alignment when cloning onto an SSD?

Perhaps that's had an effect on the performance as both your drives are cloned.

Hopefully someone can shed some light on this.
 
Before you worry too much about the figures, I would compare your Agility to the SSD thread by Andrew Moore. Although there isn't an Agility tested, he mentions the Force 3 is similar to it. And beyond the 4k write result your Agility seems to be similar.

Suppose you need to run ATTO benchmark as that is what OCZ use for their marketing.

Edit: Your AS-SSD benchmark is listing partition alignment with a green number? e.g. 1024K - OK
