Iwill SIDE-RAID100 vs. Adaptec ATA RAID 1200A
  August 14, 2001 Author: Terry Baranski  

The Benchmarks...

The following benchmarks were run with a stripe size of 64K. For the SIDE-RAID100, BIOS and driver version 1.11 was used; for the ATA RAID 1200A, version 1.0 was used.

WinBench Results...

As usual, we'll start off with some single-drive scores:

Disk CPU Utilization (%)4.76 13.13 2.93 3.04

A couple notable results. First, the 1200A's CPU utilization comes in much higher than the rest of the pack with a score of around 13%, compared to 3% for the SIDE-RAID100 and FastTrak, and about 4.75% for the MegaRAID IDE100.

Also interesting is the 1200A's significantly higher access time - on average about 0.5ms higher.

Both adapters weigh in somewhat higher in RAID 0 Disk WinMark scores with the SIDE-RAID100 scoring higher overall. It's difficult to put much faith in these numbers, however, considering the consistent issues with RAID DiskMark scores that have cropped up over the last 6 months.

In the STR arena, it's disappointing to see the 1200A limited to around 54MB/sec. This is far lower than the competition, including the 82 MB/sec SIDE-RAID100.

RAID 1...

Disk CPU Utilization (%)4.71 13.30 3.03 3.07

Both cards score virtually the same in RAID 1 as they do with a single drive. This isn't surprising given their low-cost nature.

RAID 01...

For what it's worth, the SIDE-RAID100 again wins the DiskMark battle. Unfortunately, the 1200A's higher CPU usage and access times are also present in RAID 01.
