I think everybody is quite confuse about drive and media, correct me if I am
wrong
Quantum Native Speed    Native Capacity
SDLT320 16MB/sec                160GB
SDLT640 32MB/sec                160GB will be released end of 2003
Understanding that SDLT320 support backward compatibility of SDLT220 but no
sure about SDLT640

LTO1            15MB/sec                100GB
LTO2            30MB/sec                100GB
Don't think LTO2 is backward compatible with LTO1

Media is not depend on the drive, for example if we are using Media with
160GB native, the only different is whether we are using SDLT320 or SDLT640
drive writting to the media, the media capacity still the same, only the
speed of writting to media is different.

As what u see, SDLT and LTO are in the race to each other. Personally I am
quite happy working with SDLT320.
Cheers...

It has been said that LTO2 will work with LTO1 media. I've seen nothing
about increased capacity. That does not mean that there is no increase in
capacity.

That is the native capacity. I don't know if it will do 160GB on media
which have been initialized to 110GB.

There is a road map at http://www.dlttape.com/Products/Roadmap/Default.htm

According to that roadmap , the SDLT600 will be released in Q4 2003. I
believe that in order to get 300GB native there will be new media.
