these been out?

I don't use them, but I did some research.
One gotcha that I came across was the writing speed. They can only
write at either 120 MB/sec or 50 MB/sec. There is no in between. Your

That is true, and the number of speeds depends (am I right on this?) on how
the manufactuer implemented the LTO standard. Does anyone know if there is
a way to monitor/poll/capture what speed the drive is operating at a given
time?
With
, but will write at one of 2 or 3 fixed
speeds.

But that is just the read speed of the hard drives yeah? If the data

The biggest problem is to have an architecture that can feed that
transfer rate .. because at those speed, one drive just saturates a
2 Gb FC link. ;op

I agree, in my environment I have not seen anything that can saturate a 2GB
FC link. I am thinking that choosing a drive with more speeds will give
improved real-world performance rather than a drive that can peak very
high. (although peaks of 180 MB/s would blow my socks off :) )

They have encryption capability in the drive, but it's not as simple as
just saying encryption on. You have to have something to manage the
