Norton Speed Disk Surpasses Diskeeper In NSTL Tests
Speed Disk Offers Significant Application Performance Gains, Lower Optimization Times Than Competitor
CUPERTINO, Calif. - March 22, 2000 -- Symantec Corp. (Nasdaq: SYMC) today
announced that Norton Speed Disk 5.0 outperformed Executive Software's Diskeeper
5.0 in independent lab tests conducted by NSTL, the leading independent hardware
and software testing organization for the computer industry. According to the
results released by NSTL, in this set of tests Speed Disk was not only more
consistent at improving application performance than was Diskeeper, but Speed
Disk optimizations were also significantly faster.
"As the first and most highly respected independent testing organization in the
industry, NSTL provides organizations the information they rely on to make sound
IT investment decisions," said Elizabeth Magliana, vice president of product
management, Enterprise Solutions Division, Symantec Corporation. "We are pleased
that after placing Norton Speed Disk through a head-to-head comparison with its
nearest competitor, NSTL test results concur with scores of previous reviewers
who point to Speed Disk as the most effective disk optimization tool available."
Speed Disk improved the performance of all five of the applications used in the
testing, boasting an average performance gain of 13 percent. Diskeeper, however,
improved the performance of only three of the five applications, for an average
performance gain across all applications of just 1.7 percent. In the product
performance comparison between Speed Disk/Diskeeper, NSTL employed five
applications that were deemed representative of the most common applications in
the industry and featured varied disk access patterns. The applications included
CA-ArcServe, MS-Excel, MS-Exchange/Outlook, MS-IIS, and MS-SQL. Performance
measurements were observed on the five applications at three distinct points
during testing: before disk optimization or defragmentation, after Speed Disk
disk optimizations, and after Diskeeper disk defrags.
With MS-SQL files, Speed Disk resulted in a 21.7 percent performance gain
compared to Diskeeper's 5.9 percent. In one specific test with Excel files,
Diskeeper actually degraded performance which NSTL staff attributed to free space
fragmentation, file placement, NTFS internals or the specific drive used. On
another test, Diskeeper degraded the performance of Exchange/Outlook performance
timings while performance gains through Speed Disk averaged 15.8 percent.
CA-ArcServe files saw a performance gain of 15.9 percent with Speed Disk compared
to Diskeeper's 12.4 percent.
Speed Disk also provided superior optimization times compared to Diskeeper.
Diskeeper was 41.6 percent slower, requiring an extra 9.25 hours to complete its
defragmentations on approximately 210,000 files on 19GB of disk space.
In addition, Speed Disk did not require any system downtime to perform
optimizations while Diskeeper required 23 hours of downtime of its total 31.5
hours of processing to perform file defragmentations. Diskeeper required one
reboot to defrag the server and one reboot to defrag the workstation while Speed
Disk did not require any system reboots to perform its optimization.
