a)Haven't heard that
b)160GB native/320GB compressed - it will write to the 220, but not sure if
its the same media...
c)Don't know when, but it should be 320 native/640 compressed

IBM's LTO-2 has several different speeds at which it can write to adjust to
the data stream it receives.

This is more a general backup question than specific
to networker.

At the moment I am using a tape silo with LTO (version 1)
drives. The time has come to upgrade and I have several
choices.

1) Install LTO 2 drives.
2) Buy another silo with LTO (I or II) or SDLT.

Can someone please answer the following:

a) My understanding is that LTO II will write to LTO I
        media in a different format which will give
        me 140GB on the same media. Confirm?

b) SDLT 320 uses the same media as SDLT 220 (hope I am getting the numbers
        right) and has a capacity of 160GB. Confirm?

c) When will the next generation SDLT drives be released and what is
        there capacity?


My current drives are IBM and I am not particulary happy with them.
I understand the HP drives do variable speed write. Does anybody
know if the new IBM LTO II drives will do variable speed write?

Regards,
pdg
