Adata SSD underpefrorming ?!

[SnW]

Hi guys,

I have a little SSD question, purchased this Adata a while ago and today i thought it was time to test it,

Now to the question,

its a Adata http://www.guru3d.com/article/adata-s599-100gb-ssd-review/ that one only the 64gb version (see pic below)..

see its SSD benchmark,

Its connected into sata port 1 , i updated the latest firmware from their site,

IIRC its ACHI configured or set to..

is there something obvious i am doing wrong

What Sata controller is it connected to?

Is TRIM enabled?

Edit: Good to see you around again!

Edit2: Is this the firmware you're running?

Its connected to Sata port 0 (getting the feeling this is not correct ?!)

Trim i just enabled to no luck (same speeds) and yes that's the firmware i updated the SSD with...

It shouldn't really matter what port it's in as long as it isn't plugged into a Marvell Sata3 port. The marvell controller doesn't support TRIM. You didn't test this when you put it in? I wonder if the problem was there all along or if it developed over time.

can you confirm these results, especially the sequential ones, by copying large files to that drive (will more likely go around write cacheing as you can't really disable that in windows)? the value for 4K scattered writes seems a lot too high....probably not too reliable these results. did you try another benchmark tool that would confirm those tendencies?

i encountered similar bench results (sequential: 220 MB/s read, 95 MB/s write) with a ocz vertex 2 extended (also sandforce 12xx), but this was in a Lenovo T410 laptop. so i blamed the onboard controller for that.

btw: 20 MB/s for a 4K scattered read is OK. our EMC SAN storage array @work with tons of 15K rpm drives won't get more than 4 or 5 MB/s @4K (bench taken with iozone).

Thanks BaMb1N0 but i sold it so i am all fine now
