zfs discuss - Sep 2009 - Lightning SSD with 180,000 IOPs, 320MB/s writes

http://www.dailytech.com/Startup+Drops+Bombshell+Lightning+SSD+With+180k+IOPS+500320+MBs+ReadWrites/article16249.htm

Pliant Technologies
just released two "Lightning" high performance enterprise SSDs that
threaten to blow
away the competition.  The drives uses proprietary ASICs to deliver an
incredible
input-output performance per second (IOPS) that close to doubles the fastest of
its
competitors.  The Enterprise Flash Drive (EFD) LS offers 180,000 IOPS in a
3.5" form
factor, while the 2.5" form factor EFD LB claims 140,000 IOPS of
performance.

If that''s not enough to sate the appetite of even the most die-hard
flash drive
enthusiast, this will be --  the drives also offer 500MB/sec and 320 MB/sec
reads
and 420MB/sec read and 220MB/sec write rates for the 3.5" and 2.5",
respectively.

Does anyone know list prices?

One can build an SSD-based storage device that gives you:
o 320GB of storage capacity (2.1x better than their 2.5" model: 150GB)
o 1000 MB/s sequential reads (2.4x better than their 2.5" model: 420MB/s)
o 280 MB/s sequential writes (1.3x better than their 2.5" model: 220MB/s)
o 140k random 4kB read IOPS (1.2x better than their 2.5" model: 120k)
o 26k random 4kB write IOPS (Pliant doesn''t document it)
o at a price of $920 (half the MINIMUM price hinted by Pliant )

This device is a ZFS stripe of 4 80GB Intel 34nm MLC devices ($230 each).
Now, the acute reader will observe that:
o Pliant''s device is SLC, mine is MLC (shorter life - but so cheap it
can be
  replaced cheaply)
o The Pliant specs I quote above are from their website, some press releases
  quote slighly higher numbers
o Pliant''s device fits in a single 2.5" bay, mine requires 4
o Pliant doesn''t quote random 4kB *write* IOPS performance - if I were
a
  potential buyer, I would ask them before buying

As a side note, I personally measure 15k random 4kB write IOPS on my Intel 34nm
MLC 80GB drive whereas Intel''s official number is 6.6k - they probably
give a
pessimistic number representing the performance of the drive after having been
aged.
