[geek] Opinions on RDX hard disk cartridges?

Opinion question from those who use tape drives or VTLs:

http://www.rdxstorage.com/

Think this actually lives up to the billing of being a tape drive replacement for SMBs? The drive costs $650 internal, $680 external, media is $490 (from CDW) for a 500GB cartridge. Compare this to about $3000 for a LTO-3 (which stores 400GB native) and $40 per LTO-3 tape.

The difference between this and just buying external disks is that the actual hard disk drives are 2.5" enterprise-grade HDDs (as opposed to 3.5" consumer grade ones) and come in a shock-resistant case. From what I read, the MTBF (mean time between failures) on the drives is in the million hour range... but MTBF isn't everything. It tends not to cover media that is unmounted and left in storage for years.

I'm just idly curious. I've seen removable disk solutions come and go, but this one seems to have some backing behind it.

It looks like it's simply another flavor of external USB drive or something. I don't see what justifies the exorbitant cost.

I agree with Hidle. I don't really see the difference between this and a well-engineered hard drive enclosed in a good case, unless guarantees of data preservation are critical to what you're doing.

I agree

You could get 1tb and larger enterprise-grade HD in 3.5" and used them in an external tray enclosure.

We use trayless enclosures at work with enterprise-grade HD for backup.

Their main advertising is that the cases are standardized, and that they can be used in an autochanger, so one can set up a bunch of cartridges, let the backup program do a copy, then yank the ones that go offsite.

However, I agree about the cost. $500 for 500 gigs is insane. Buy 10 tapes of a LTO-3, and you are far more ahead, and 10 tapes is nothing when it comes to backing up.

The main thing the RDX system has going for it is that it appears well engineered.
