We get pretty much the same speeds. We run a Quantum PX502 and I think
it is pretty much maxed out at 80 meg/sec per drive.

The group I work with is expecting 160-200MB/s megabytes per second on
an 
LTO3 with compression.  I did some tests today with 7 RAID1 SCSI drives.

67GB x 7

On each volume was 3 20GB tar files.
I got 78-82MB/s sustained total, 12-16MB/s on each thread (7 
multistreamed).

The tar files are representative of a typical file system in our 
environments.

What speeds have other members gotten when doing speed testing to LTO3 
drives?

Justin.
