Phase-change memory device knocks SSDs off their perch

For smaller accesses, for example 512B, Moneta can read at 327 megabytes per second and write at 91 megabytes per second - between two and seven times faster than a state-of-the-art, flash-based SSD.
Huh? 327mb/s read is 2 to 7 times faster than current SSDs? And a write speed of 91mb/s also isn't something to write about (if that was really 7times faster there would be current gen SSDs out there with 13mb/s write speed - and nothing about the access patterns)
Also it's trivial to get higher numbers with SSDs - just throw more flash chips on a die, but the price is prohibitve - and they seem to tout the performance and not price reductions of this technology..

Nope, not especially impressed.

It's 327 mb/s read for 512 bytes. I think the best SSD can read 30+ mb/s read for 4096 bytes and SSDs transfer slower at lower bytes. Of course with NCQ SSDs can do over 100 MB/s for 4096.

It also says that UCSD is using 1st gen PCM tech already from Micron. Take note that earlier this year UCSD is the same university that released studies on SSDs. So they're making progress playing and pushing with tech. Wish I had those courses when I was in school.
