Quantum's DLT VS160 is able to store up to 80GB of data (160GB with compression) onto each cartridge. It's also very quick, with sustained transfer rates of 8Mbytes/sec (16Mbytes/sec with compression). But the extra capacity and speed come at a price.
The VS160 is based on Quantum's own DLT technology and uses the same bulky square cartridges that remain visible when loaded into the drive. Special VS1 format cartridges are required to get the 80/160GB capacity. However, it is possible to read backups created with earlier VS80 and DLT1 drives.
The bulky cartridge format also makes for a large drive, the VS160 requiring a 5.25in slot for internal mounting. On the plus side, the mechanism is only half-height and still relatively easy to accommodate, even in a modest free-standing server.
As well as the bare internal drive, Quantum sells a self-powered external version of the VS160 plus a rackmount implementation for use with rack-dense and blade servers. Ultra160 SCSI is used for the interface and you may also find the drive used as the basis of automated tape libraries.
Quantum doesn't bundle any software, but the popularity of DLT means that it's supported in all formats by every software vendor. That popularity also makes it easy to get media, although the cartridges were a little costly. Indeed, on a cost per gigabyte basis, they were one of the most expensive.
On an entry-level server, the capacity and speed of the Quantum DLT VS160 are unlikely to justify the extra costs. However, those benefits are worth paying for if you've a lot of data to back up in a small amount of time. You'd need to spend a lot more to better what the VS160 has to offer there.
