testing of server, network, storage and security technologies, for the small and
medium business (SMB) environment and the large enterprise. Demartek conducts
research and lab testing resulting in white papers and product comparison
reports.
- editor's comments:- in November, 2010 -
Demartek
published a sponsored
test
report (pdf) which compares the performance of
SSDs and
HDDs in a simulated
web server environment when managed by LSI's
CacheCade
software - which provides
SSD ASAP
functionality.
Editor's commnents:- The report shows that
throughput and access times were improved by at least 3x using a single
SSD cache compared to the HDD only situation.
However - it's
disappointing that the sizing of the test was not best chosen to draw
meaningful conclusions. Because the web content was only 25% larger than
the SSD capacity! It would have been more helpful to design a simulated case in
which there was at least a 10x or 100x size difference. Because if you
can fit all the web content onto an SSD then you don't need the burden of the
"cache" software at all - and might get better results by switching it
off.
There are case studies going back nearly 10 years which show that
SSDs can provide big speedups in web servers. The exact speedup depends on how
fast the SSD is. This test report doesn't answer the question - is LSI's
CacheCade useful in a realistically scaled environment?

| Top 20 SSD companies
- (14th quarterly edition)
|
Editor:- Which companies do
you absolutely have to include in your thinking if you've got any new
projects involving SSDs?
And which SSD companies are most likely
to succeed?
With hundreds of manufacturers already in the SSD
market - and hundreds
more soon to enter
- you have to know where you should prioritize your valuable time and
attention.
For more than 3 years
StorageSearch.com has published the
quarterly list of the Top 10 SSD companies - which has accurately predicted the
ebbs and flows of existing vendors and has been sensitive enough to recognize
the industry's new rising stars from the background noise of the
SSD bubble's hype.
Unlike
editor or analyst
pick lists - this is based on the scientific method of tracking and analyzing
the search volume of the most important people who will decide the future of
the SSD market - the millions of people - who like you have been reading our SSD
content.
Each edition of the list includes a list of the top companies
and a review an analysis of key SSD market milestones in that quarter. By
comparing successive listings you can also see - who is on the way up and who is
on the way down. |

The listings have been
recently expanded to include the top 20 SSD companies - so you can get better
visibility of which companies are hot on the heels of the leaders. ...read the article | | | |
