Show us your SSD performance 2

Thanks, Gary. For a single SSD drive to get Read speeds of 500MB/s+ and 2 drives in RAID 0 speeds of 1000MB/s+ is getting towards the interface speed limit, bearing in mind that it is 600MB/s and that you have to factor in operational overheads. I note that your Write speeds aren't as high as mine were when I was running non-RAID, but it is chiefly the reading of data and the speed at which it can be read that governs the overall feeling of speed of the computer.

In order to be able to go faster than 1000MB/s, we would need to increase the number of drives so that more SATA channels are employed for the array. For example, 3 drives should yield a speed of ~1500MB/s and 4 ~2000MB/s (I wonder if anyone has tried or could verify that?) and that really would be a lightning fast system.

Based on advice I reverted to Intel RST 11.2 with considerable improvement in my benches. Unfortunately I don't have a copy of my earlier actual runs using 11.6 and 11.7, but they were definitely not at the same level.

Your 4K times are fantastic - and that is really all that counts for the OS.

Actually, (and it is one heckuva coincidence) it was you in a post long long ago that made me aware of the importance of 4K speeds for normal use. A belated thanks for that.

LOL, looks that sometimes my posts are useful. And you are very welcome.

A few thousand of your posts are useful.

Gary, that's very kind of you to say that. Makes an old man feel 2 feet taller. Now the wife has to look up even more - she is only 5 foot 2 inches.

Was unable to get the Vertex 4 drives I was thinking about, but got a new pair of OCZ Agility 3 SATA III 120GB drives instead. Configured as RAID 0, here is my ATTO benchmark result.

Great speed, that's a nice setup.

Seriously, having seen the figures that Wolfgang posted of a friend's machine, I'm considering another upgrade and going for a pair of OCZ Vertex 4 SATA III 256GB drives in a RAID0 configuration. My other SSDs (the ones I currently have installed) will go into my other computer that I have built using the components from my previous system. :)

Zoooom... Great results Guy

Some additional tweaking (stripe size) and system overclocking (I'm not sure if overclocking makes any major difference) results in better 4K for Vector (256 GB) X 2 raid 0

With those nums beware of whiplash, lol.
