Re: Tape vs HDD vs NAS (speed considerations and size etc)..

Yeah LTO-3 is what I was considering.. but the cost per tape, I believe
was kinda high, considering the number of them we'd need for a full
backup set (two of them to alternate offsite each week, etc).

I'm pretty sure our 350gb backup that we do runs about 10 hours or more
to SATAII's.. I forget, but I think the specs on some LTO's were only
around 20mB/s, so that would take 2x as long if so.

LTO3 from Quantum is rated at 68MB/s native.
LTO2 from Quantum is rated at 26MB/s native.

The best 3.5" 7200rpm drives are managing about 70MB/s write performance (that's WD Raptors, Seagate Barracuda 7200.10)
