Great post Wes, You got me going out there researching myself...and I found these other interesting articles to add to your posting....
IBM White Paper: Comparison IBM LTO Ultrium versus Super-DLT Tape Technology http://www.storage.ibm.com/hardsoft/tape/lto/prod_data/ltovsdlt.html The LTO organization web site. http://www.lto.org Quantum announcing 160GB native and 16MB/s native transfer rate. They are calling it the SDLT 320, available in 2ndQTR this year. http://www.quantum.com/News+and+Press/Press+Releases/03-12-2002.htm Cheers, Leonard > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED]]On Behalf Of Wes Owen > Sent: April 1, 2002 8:38 AM > To: NT 2000 Discussions > Subject: OT: LTO VS SDLT > > > There was a thread last week where backup hardware came into > question so I > thought I would post this as another opinion.
