2.5" SSDs marketed
In June 2010 -
offered consumers a 64GB version of their
6Gb/s SATA SSD for $149.99 - with R/W speeds upto 355MB/s and 75MB/s
Some consumers may have been dazzled by the 355MB/s
speed which sounded like it was even better than many enterprise SSDs...
High read speeds provide a good experience in popular consumer applications like
games. But imbalanced
R/W speeds do little to impress enterprise users - and many 3Gb/s
enterprise SSDs would outperform this product in general purpose apps (even
with only 1/2 the read rate).
The best introduction to the interplay
of read and write IOPS in flash SSDs (because it's
are the important element of performance in general purpose apps - rather
than simply bulk R/W throughput) is still the classic (2007) paper
Flash SSD Performance (pdf) - by Douglas Dumitru, CTO
the ratio of time spent doing each activity in enterprise apps which can mean
that low write IOPS negate most benefits of high read IOPS.
