Just recently purchased an IBM 200/400G LTO-2 (internal) drive. And the
sucker is -SLOW-. Amtapetype ran for over 24 hours and didn't finish.
I'm running the Bacula tape test util right now for a full tape write,
and in the past... 21 hours, it's progressed to 14G, and reporting a
rate of around 200 KB/s.
Now, for a drive that reads 'up to 35MB/sec native data transfer rate
(70 MB/sec with 2:1 compression)' for sustained data transfer rate on
the product datasheet (I know, I know, 'marketing speak' and all... But
one has to admit, there's a -huge- discrepency between 35 MB/s and 200
KB/s. -.- ), that's a -slow- drive we have.
So, I was wondering. Has anyone else had experience with this
particular drive model before? Are they all this slow, or did we just
get 'lucky' here...? (Before it's asked, no, the SCSI controller is not
throttled. While it's tweaked down on the secondary SCSI chain
(external DDS-3 changer), the primary has not had any limiting done on it.)
