hi
this has probably been asked a lot but i'm wondering why my agility 3 gives only ~200/~100 read/write speeds in CrystalDiskMark ?

i have AHCI enabled in bios.

and another question should i use RAID because my board has integrated marvel raid controller? (device manager shows this)

The cable itself does not matter (from what I understand the only changes in the cables are the clips on the ends).

Although if you have a SATA3 cable that came with your motherboard you can try it, but I wouldn't imagine it doing anything differently.

You will want to make sure that you are using the gray port on the motherboard. The red port is from the Marvell controller which doesn't give near the performance that the Intel ones give.

hmmm

yes it does have that third one (dark blue) besides them:



i guess that's the one to avoid.

OK changed the slot now to grays. But ATTO gives wierd readings for agility 3:

that's good or bad?

(looks like half the agilitys max speed)

Your MB specs said "ASMedia® USB 3.0 controller". Unfortunately Sandforce 22XX based SSD are not known to play nice with non-native controllers such as Marvell, etc. Native controllers are Intel or AMD. Maybe there's a controller/BIOS update?
 
One more thing... post a pic. w/ AS SSD Benchmark open after a run. And try disabling C3/C6 States in the BIOS, along w/ setting the Win7 power option plan to High Performance. Also make sure that under Power Options--> Advanced Settings--> Hard disk--> Turn off hard disk after: is set to Never.
 
ok thanks been busy so couldn't answer earlier. I have tried everything except C3/C6 States so far (they are CPU states?).

and i found out the drive is running at 3gb/s SATA transfer rate. But I don't know why, it's on 6gb now.
 
ok did that but it didn't help.

still 3gb transfer rate reported also.
 
any ideas? it seems to run at 3 gb/s . but i have no idea why.

tried installing some drivers, marvel etc but no help

Just curious, is it a "bad" thing to have your computer go into sleep mode with an ssd? I kinda like having my computer goto sleep after 30 minutes of idle... it saves on my already crazy high energy bill (I live in Miami and my A/C hardly ever turns off).
 
data1 have you figured it out yet? I'm in the same exact boat. I also have an OCZ Agility III SSD (240GB) and from what I gather it is aligned and I've done most of the tweaks (disable page filing, superfetch, prefetch, defrag; enable High Performance and AHCI in BIOS) and it is connected to SATA1 6GB/s (grey port). I'll post my results. Have yet to use AS SSD or ATTO as I'm sure they will report similar numbers.

This is discouraging...

Perhaps I'm missing an MB driver/BIOS update?

no i haven't found any solution yet.

i contacted both my motherboard tech support and the SSD tech support but after everything was checked there was no solution.

It's weird the reported running speed of the drive is infact 3Gb/s which implies the drive would be somehow locked or bottlenecked to run slower . the correct speed of the drive is 6gb/s.

and it's not because of wrong cable or port....
