New Vertex2 SSD - my HD Tune bemchmarks are weird

BazBell · 6 Nov 2010 at 13:54

I just installed a new OCZ Vertex2 60GB SSD. When I run HD Tune the temperature readings are crazy, it's either 1C or 80C with the warning "critical hard disc temperature". The drive is cold to the touch.

Also, from what I've seen HD Tune benchmarks for this drive appear to be a zigzag line going steadily across at about 225 MB/s but my are really strange, see below. Any suggestions why my drives benchmark looks so weird?

Use Atto to bench SSD's.

Hi shoot1st

Thanks for the reply. I've just done a bench mark with atto, I'm uncertain what I should be looking for. I don't know why the readings seem so low in the 0.5 - 8.0 range, does this look normal to you?

Do you have any idea why the HD Tune benchmark looks different to most I've seen?

I'm not 100% sure why ATTO is preferred tbh but OCZ themselves recommend it due to something to do with how the Sandforce controller works - compressed and uncompressed data or something iirc. Have a look over at the OCZ forums as I'm sure there'll be a proper explanation somewhere if you need to know a definitive answer.

The speeds you're getting with the drive look perfectly fine to me, same as what I get with that drive anyway, and most others.

Edit: Don't run bench after bench on the drive as it just slows it down the more you do it apparently, lots of small files or something iirc, run ATTO to make sure you're getting the speeds and then leave it alone is the general advice.

Thanks for the tip

Sandforce controllers reduce the drive speed if you run it multiple times to prevent damage. If you ran ATTO 20 times you'd slow writes to a crawl, check again after 5 days it'd be back to normal once you'd stopped thrashing the poor thing

I like a good thrashing now and again

Is it the speed at which data is written to the SSD in benchmarks or the amount of data written, that slows the SSD down for a few days? I was wondering if installing a few big games/apps in 1 day would have the same effect?
