SSD roundup: Vertex 3 vs M4 vs C300 vs 510 vs 320 vs x25-M vs F120 vs Falcon II

About the chips, what do you want me to ask exactly ?

Maybe you could ask how they know the page size of the flash chips. Do they have a spec sheet from Micron that gives the page size for those flash chips? Is it possible they got the specs of the 32Gbit 34nm flash chips confused with the 32Gbit 25nm flash chips?

Hi John,

It's intriguing the way performance is coming out at QD 1 with 4k random reads.
• C300 128 is 3% faster than the C300 256
• OCZ V3 120 is 5% faster than the V3 240
• M4 128 is 19.7% faster than the M4 256

At QD 2 and above the larger capacity models become faster. That makes me think it is not an anomaly in the testing, although maybe that could not be excluded when differences are less than 5%.

With the Intel 510 & 320 however there is no significant difference between the different capacity drives at QD1. Above QD 1 and the 120 version of the 510 is faster than the 250. With the 320 it is the other way around.....but here we are comparing different controllers

Ok, understood.

I mailed him, I'll keep you updated when I get some info

Cool thanks. Did you ask him about the trace issue as well?
