SSD performance - 12-15-2008, 04:25 PM
I know many are eagerly awaiting the runcore SSDs and it seems like they are arriving for the first orders (hopefully). After reading through this anandtech article, I was wondering if anyone would be willing to test the latencies on the Dell drives and the newer runcore drives? Sure, the anandtech tests were on a beffy quad-core desktop, but the write latency on the SSD drives with the JMicron controller were abysmal, so even if it shoulnd't matter that much on a 1.6GHz Atom processor, I'm still curious if the SSD latencies are going to be that slow on the runcore.
I think IOmeter primarily is a windows based program, but you may be able to run it on an Ubuntu system. Even if no one can/wants to go that in depth with a program like IOmeter, there are some real world tests like compressing and uncompressing two different archives at the same time. And while I know this seems overkill, the author noticed the pauses while IMing, which is something most people would do on a netbook.

As for that pause you quoted.. The old generic MLC SSD's that MyDigitalDiscount was selling have that problem. It'd actually pause up to 10 seconds at times. Those drives were also horribly unreliable and they pulled them off their store. From the video posted online by JKKMobile of the RunCore, they don't have this problem. He worked the hell out of his machine while playing video and such, no stuttering seen.
Hell, all it takes is a semi decent controller on the drive to take the info from the OS, cache it, and say "ok, got it, you may carry on now" to the OS so the OS never stutters, and the write speed of the drive is hidden in the background.
