Hi,

We're using Intel 320 series. Cluster is running now half year as
production and no problems with ssds.
Replication x3 (main DC) and x2 in backup DC (10 nodes cluster there = less
space).
From what I've notice it's

That's not the only thing you should worry about.
Aside from the higher risk there's total cost of ownership or Cost per
terabyte written ($/TBW).
So while
Hi,
I'm looking to build a full osd ssd cluster, with this config:
6 nodes,
each node 10 osd/ ssd drives (dual 10gbit network). (1journal + datas on each
osd)
ssd drive will be entreprise grade,
maybe intel sc3500 800GB (well known ssd)
or new Samsung SSD PM853T 960GB (don't have too much

What is your main goal for that cluster, high IOPS, high sequential writes
or reads?
Remember my Slow IOPS on RBD... thread, you probably
(like crucial m550), I think I could
reach 2000-4000 iops from it.
But I'm afraid of durability|stability.
