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

yes i read this a few weeks back. i have emailed Intel about whether or not they have an audio on the presentation like they did on the last IDF> no response

looks to be moving to traces to measure ssd is the way to go. if you look at PCMark7 i believe they will be moving more towards this very method of quantitative measuring of performance, they do state that they will no longer measure theoretical peaks of bandwidth to measure storage performance.

Even if it was assumed that benchmarks were correct any real life benefit is hamstrung by the OS/ Apps/ CPU/ GPU.

that might be a bit of an oversimplified blanket statement there that would be hard to make given the data. there are differences, but they are hindered by OS/APPS/CPU/GPU, not eliminated. as he points out on page 25

Some SSDs in 3-4 sec range, others 5-7 secs

that is a big difference. 3 seconds compared to 7 seconds is a large margin. percentage wise your looking at 67 percent difference.

he does sum it up nicely towards the end by saying "ecosystem improvements needed to showcase "ssd class" performance.

we need new filesystems. also, new games that are coming will access data differently when they detect an SSD, and this is jut the beginning of apps that will change their access patterns when ssd are detected. just will take time. they talked alot about those changes in last years IDF.


it is VERY hard to make a complete reasoning from the PDF alone. we need the audio to really put it together. they did these for san fran IDF, but for Beijing i cant find the whole presentations. GAH i wish we could get them...
