RE: I like the new RDX docking station... Just sayin



fixed

Sure, your laptop. The drive is essentially the same thing. Potential for
failure, sure, but most of those drives are very reliable. Tape has
magnetic drop out. Drop and LTO tape cartridge, or an RDX you're going to
replace both of them anyway.

Use what's most comfortable for you but with P8 the RDX unit is going to
start getting some attention.

What makes me curious about RDX is how much reliability the disks have.
Disk drives have various failure modes (controllers, bad sectors, etc) and
depending on how the disk is written it might not have the same ECC that a
tape has...
Are there any good comparisons?

BRMS restrictions for optical devices apply to RDX, see the

information.

Same way you do with tape except use DUPOPT instead of DUPTAP.

How would you create a DUP of an RDX for off-site DR?

Comparing RDX cartridge prices to LTO3 or LTO4 tapes you won't like.
RDX
is a lot more money for sure one to one.

--BUT--

With Power8 for example there is no longer an internal tape option.
So
you'll need purchase a SAS card, SAS cable, and an LTO drive such as
the TS2900. You will be out a pretty large pile of RDX cartridges just
to get the LTO drive! In comparison the RDX drive itself is almost Free!

So for the small shops RDX will be much more economical than LTO.

I think the RDX cartridges are still relatively expensive when
compared
to a regular hard drive in a removable dock, but it's a different
horse as well from what it sounds like.

Don't suppose a BlackX USB Dock can hook up to the I nowadays can it ?

Personally I think comparing to the times of saving to save files
isn't
too impressive.
A decent LTO3 or above tape drive, with enough processor to drive
it,
will often blow the doors off of saving to save files.
This isn't 1970. Disk isn't always faster than tape. Especially
when
you're using the same disk controller, set of arms, etc to write the
data as are reading the data.
