Quantum SDLT 320
The SDLT 320 represents a major advance in capacity
and performance. It offers the lowest cost per GB of any other storage
solution on the market and, as part of the DLTtape product family,
enjoys the highest industry acceptance. The SDLT 320 is backward
read compatible with DLTtape IV media and uses the same Super DLTtape
I cartridges as the SDLT 220, preserving your data storage investments.
Specifically designed for the high duty-cycle requirements of high-end
and automated environments, the SDLT 320 is the ultimate solution
for today's demanding backup needs.
- Native capacity of 160 GB at 16 MB/s transfer rate
|
- 2:1 Compression allows 320 GB at 32 MB/s
|
- 250,000 hours MTBF at 100% duty cycle
|
- Fully backward read compatible with DLTtape IV cartridges
and uses Super DLTtape I media
|
- Advanced Metal Particle Media embeds the optical servo
tracks onto the reverse side of the tape freeing up 100%
of tape's magnetic side for recording data
|
- High efficiency PRML Channel creates more tracks on the
tape
|
- Laser Guided Magnetic Recording combines best of optical
and magnetic technologies
|
- Pivoting Optical Servo increases high duty cycle reliability
|
- Magneto-Resistive Cluster Heads for the highest data density
|
- Increased media capacity provides easier use and lower
cost of ownership

Data
Sheet
The ideal choice for high-end and automated environments,
the SDLT 320 is designed for high duty-cycle with a rating of 250,000
hours MTBF at a 100% duty cycle. It can backup 115 GB per hour (in
compressed mode), and can store 320 GB on a single cartridge (compressed)
offering the lowest cost per GB and the highest storage density
around. The SDLT 320 is backward read compatible with DLTtape IV
media and uses the same Super DLTtape I cartridges as the SDLT 220
allowing seamless migration to Super DLTtape and preservation of
your data storage investments. It is also fully compatible with
the leading server brands, operating systems and backup software.
