SSD running slower than expected.

Hi all,

I'm sure i'm not the first to post about this.

I've had my SSDs for almost a year. I ran a novabenchmark today and saw that my SSD r/w speed was 100mb/s... :eek:

I have a couple of these and I assumed they'd be running x5 faster! Couldn't believe that I was wasting their potential!

I never thought to check or read up on installing and SSD. My ignorance led me to believe that as long as it was plugged into a SATA III 6gb/s slot it would be fine. Guess I was wrong.

After a ball ache of an evening I managed to change my BIOS settings from IDE to AHCI without having to reinstall windows.

It has made an improvement but not as much as I was expecting.

The SSD in question is partitioned. 80GB for Windows and the rest for programs. Unsure if this will make a difference.

Someone suggested an ATTO benchmark and I think it actually is running OK.

Comments?

Damn PC won't boot this morning.

Can't find bootable media!

Tried going back to ide, no change.

Going to have to make a bootable USB I guess.

first off make sure the SSD is connected to a Sata 3 port on the motherboard and make sure ACHI is enabled as well in the bios.

might be worth checking if there is any firmware updates for them as well.

hmm not sure but if that drive uses a sandforce controller then you can just write it off now as dead.

ED209 · 18 Dec 2014 at 11:03

Taken from the above link

Controller: SandForce SF-2281

should still be able to get the read and write speeds advertised though?

wazza300 · 18 Dec 2014 at 16:21

atto is the benchmark to use for all sandforce controlled ssd's it will give true speeds

gunnerzz1008 · 18 Dec 2014 at 16:24

PC back up. Yep its set to AHCI and connected to SATA 3. So you're saying that it is running at the speeds it should?

wazza300 · 18 Dec 2014 at 16:30

yeah atto is correct,as ssd benchmark will show lower because of non compressionable data

Thanks guys
