| Are MLC SSDs Safe
in Enterprise Apps? |
This is a follow up
article to the popular
SSD Myths and
Legends which, a year earlier demolished the myth that flash memory
wear-out (a comfort blanket beloved by many
RAM SSD makers)
precluded the use of flash in heavy duty datacenters.
This new
article looks at the risks posed by MLC Nand Flash SSDs which have recently
hatched from their breeeding ground as chip modules in cellphones and morphed
into
hard disk form
factors. |

It starts down a familiar
lane but an unexpected technology twist (which arrived in my email while
writing this article) takes you to a startling new world of possibilities.

yourself - may surprise you by running much slower when deployed in
your own applications due to common "halo" errors which are implicit
in the set ups of many performance test suites which were originally designed
for HDDs. ...read
