rackmount SSDs
Earlier
versions of this document only listed the single fastest rackmount SSD in each
u-size (1U, 2U etc) - but there were some disadvantages in that method because
the listings were dominated by RAM SSDs - even though flash SSDs represented the
realistic choices made by most users.
To make this rackmount SSD
list more useful I've changed this section to include the top 3 or so
companies in each market/
application silo.
You'll have to look at each vendor's own
offerings to get the exact specifications - but these are the vendors who are
positioning themselves as the companies to beat in each of these market
segments.
- fast-enough rackmount SSDs (budget priced):-
Skyera,
SolidFire, and
Pure Storage - as
well as all the companies in the "fast" category above.
Speed
has a different value in
fault tolerant
rackmount SSDs - where the raw latency and IOPS may be outweighed by user
preferences about the exact design and consequences of the differing FT
architectures. |

During 2012 -
several vendors (including HGST
and Seagate) have
demonstrated 12Gbps SAS SSDs. The specs for these products haven't been finally
released - but they will most likely replace the fastest SAS SSDs shown
below - which are 6Gbps related performance numbers. |
