- editor's comments:- June 2010 - Lexar markets
ExpressCard SSDs
and
2.5" SSDs marketed
under the Micron
Technology's Crucial
brand.
In June 2010 -
Lexar Media
offered consumers a 64GB version of their
2.5"
6Gb/s SATA SSD for $149.99 - with R/W speeds upto 355MB/s and 75MB/s
respectively.
Some consumers may be dazzled by the 355MB/s
speed which sounds like it is 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
IOPS which
are the important element of performance in general purpose apps - rather
than simply bulk R/W throughput) is still the classic (2007) paper
Understanding
Flash SSD Performance (pdf) - by Douglas Dumitru, CTO
EasyCo.
It's
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.

| Editor:- understanding the
list of ingredients inside flash SSDs - is as important as knowing what
you can do with them - and
a new article published
on
StorageSearch.com tries to hit this fast moving target. |
"Just as some
foods are healthier than others - so too some SSDs are better suited for
particular applications" says editor Zsolt Kerekes.
"Better
user education about SSDs is a critical factor for the industry to sustain its
growth. Design tradeoffs in products go far deeper than the choice of memory
and interface. Being aware that there are other parameters which SSD vendors
have implemented well, badly (or not at all) can be the difference between a
satisfactory or disillusionary experience." ...read the article | |
