I’d second both of these points, but
especially the pricing one. When we looked at it, pricing was based on the
volume of data pre-deduplication, and bought in blocks of n Gigabytes or
Terabytes.
I had two big issues with that
1) From a business point of view the one of the big value point of
dedupe is to reduce the storage/transfer costs of backup. But their pricing
model means that rather than spending that money on infrastructure (local tape,
faster links, whatever), we pay that money to veritas/symantec. OK, fine, it’s
probably less money over all, but even so to me it means that Symantec is
getting the lions share of that value from the software, not me. I actually
think this will change somewhat as dedupe becomes commodity.
2) Volume based pricing often stings you 2 or 3 years in. Sure, right
now paying $n to backup x TB might seem cost reasonable, but the
midrange/highend vendors never seem to drop their $n per x ratio at the same
rate as the rest of the industry – so in two years time, you may find
yourself justifying quite high cost per gig upgrade, just because you added 3
remote sites, and suddenly have to buy another data block. And you no longer
have the bargaining position of being a new customer. Which leads me back to my
first point – why am I buying another data block when 50-80% of that data
is going to be de-dupped from other sites anyway?
Had their pricing been the same per tb,
but based on the de-duped data size, not the pre-de-duple, we probably would
have signed up.

PureDisk is great for backups but you have to have a serious look at your
restore requirements. For example, if you have a double-disk failure in a
RAID5 set at a local office and lose a large raidset, you could be restoring by
shipping disk drives rather than a network-based restore.
For a restore of a word processing document or spreadsheet, PureDisk is
fantastic. If you anticipate restores of a user's 10GB PST file, this
could become painful.
That said, we really like PureDisk technically. We still don't like the
price...
