Burhan,
I based my figures on articles I read, and here's a quote of one of them:
"Limited write cycles – usually Flash storage will wear out after
300,000-500,000 write cycles, while high endurance Flash storage is
often marketed with endurance of 1–5 million write cycles" --
http://en.wikipedia.org/wiki/Solid-state_drive
That's for flash based storage, not DRAM based ones.
SSD Write limits are charted here: http://wiki.eeeuser.com/ssd_write_limit
This has nothing to do with a specific vendor, but with the
underlaying technology being used to make these disks.
Bashar,
I have a friend who just got himself a NetGear NAS upon another dude's
recommendation and he's quite happy. It even runs Linux and you can
install apt-get on it to install more packages!
As for myself, I don't bother looking for ready-made NAS boxes. I made
my own! 3.7TB of storage (so far) and still have space to slap in more
disks.
