Introduction
3
The Scorpion 40 provides superb reliability through three levels of error-correction
code (ECC) and the four-head design, which provides for read-after-write (RAW)
error detection and correction. The Scorpion 40 also includes a “flying” preamplifier
for greater signal-to-noise ratio.
Features
The Scorpion 40 DDS drive represents Seagate’s commitment to engineering
reliable and durable tape drive products that implement leading-edge technology.
Key features of the drive include:
•
Platform based on state-of-the-art drive mechanism and tape handling
components sealed in a dust-free enclosure.
•
Three form factors available: 3.5-inch internal form-factor for installation in a 3.5-
inch half-height space (model STD1401LW); 3.5-inch drive with factory-installed
5.25-inch mounting rails and bezel for installation in a 5.25-inch half-height space
(model STD2401LW); and external subsystem with built-in, auto-sensing,
worldwide power supply (model STD6401LW)
•
ANSI/ECMA compliance and capability to write and read DDS-4, DDS-3, DDS-2,
DDS-DC and DDS cartridges. (The Scorpion 40 can use 90-meter DDS-1 media
but not 60-meter DDS-1 media).
•
Advanced onboard DDS-DC hardware using Data Compression Lempel-Ziv
(DCLZ) data-compression algorithm
•
High-speed transfer rates for fast backups:
– 2.75 Mbytes per second typical—uncompressed data
– 5.5 Kbytes per second typical—compressed data
•
High-performance SCSI burst transfer rate of 10 Mbytes per second
asynchronous and 80 Mbytes per second synchronous
•
Flash memory to store setup parameters and enable field firmware upgrades
•
Four-head design with RAW error detection and rewrites
•
Three levels of ECC to ensure data integrity
•
Uncorrectable error rate of less than 1 in 10
15
bits
•
Custom Seagate-designed LSI circuitry to reduce component count and boost
drive reliability
•
LVD / Ultra Wide SCSI connection
•
Automatic power-on self-test
•
Support for TapeAlert™ Certified Solutions
