Analysis
So far, this has been the fastest
drive tested here. The lct line of drives are the newest from
Quantum and really push the envelope of hard disks running at 5400 rpm giving us
257Mbits/sec. The lct10 goes beyond that to offer an internal transfer rate of
294Mbits/sec! Though rotational speed is the same as the other CR and CX drive,
the Fireball lct sports 8.7GB per platter while the CX delivers 6.8GB per
platter.
In effect, increased areal density increases the amount of
data retrieved from the drive per rotation. To give a slight boost to
performance, the Fireball lct is the first 5400 rpm drive from Quantum to see
its access time spec go below 9ms. It is 8.9ms to be exact.
Quantum's Data Protection
System
DPS is the brainchild of Quantum Corporation which tests the
integrity of a Quantum hard disk drive that supports this feature. For users of
Quantum Fireball and Fireball Plus drives manufactured after January 1999, the
DPS is available in the drives firmware. For users of older ATA drives, DPS is
available as a standalone program available from Quantum's
website.
The following has been taken from the Quantum DPS White
Paper
How DPS works
DPS performs a Quick Test that
exercises the hard drive. In addition, DPS checks every sector in the drives
buffer and examines the first 300 megabytes of data stored on the drive, where
the operating system and other critical system utilities are typically stored.
Within 90 seconds , the Quick Test is complete. The results confirm whether the
hard drive is the source of the system failure.
DPS Extended
Test
If the DPS Quick Test results find no errors in the first 300
megabytes of data and the system continues to malfunction, the end user can run
the DPS Extended Test. This test performs all Quick Test functions, and it also
examines all additional data areas to verify whether the hard drive is the
source of the problem. The time required for the Extended Test depends on the
capacity of the drive, but never exceeds 20 minutes.
Summary
Quantum's DPS helps prevent avoidable data loss.
By determining whether the drive is the source of a system-level failure, DPS
spares users from unnecessarily removing and replacing a perfectly healthy
drive. Valuable data is protected and productivity maintained. Systems
integrators, distributors, resellers, and OEMs also benefit from reducing their
service costs and -- most importantly -- maintaining the goodwill of their
customers. Quantums DPS thus provides a comprehensive solution to avoidable data
loss for desktop computer users and their suppliers alike.
