The Promise SuperTrak SX6000
 October 31, 2001 Author: Terry Baranski  


IOMeter Scores...

Base Scores...

Baseline with 1 Drive

What stands out from the above scores is the SX6000's poor write performance - both random and sequential. Performance in our core tests (File Server, Workstation, and Database), however, is as expected.

RAID 0...

RAID 0 with 2 Drives
RAID 0 with 3 Drives
RAID 0 with 4 Drives

As the above graphs demonstrate, the SX6000's performance is remarkably improved relative to the ST100. Scores in our core tests scale nicely as drives and outstanding IO's increase. Core test scores remain lower than those of the Escalade 7410 and ATA RAID 2400A, however, particularly in the Workstation pattern. Write scores are disappointing - for whatever reason, the SX6000 seems to be limited to about 4.5MB/sec of STR per drive. Random write performance isn't anything to boast of either, unfortunately.

RAID 1...

RAID 1 with 2 Drives

Like the Escalade 7410 and ATA RAID 2400A, the SuperTrak SX6000 boosts RAID 1 performance by load balancing random reads between both drives - a positive thing, indeed. Scores aren't quite up to the level of the competition, however, and write performance continues to be poor.

RAID 01...

RAID 01 with 4 Drives

Scores again greatly improve upon the ST100, but remain behind the competition.

RAID 3...

RAID 3 with 3 Drives
RAID 3 with 4 Drives

Unsurprisingly, the SX6000 does a lot better than the ST100 in RAID 3.

RAID 5...

RAID 5 with 3 Drives
RAID 5 with 4 Drives

In RAID 5, the SX6000 does particularly well against the Escalade 7410, topping 3ware's offering in most tests. It performs significantly worse than the ATA RAID 2400A, however, which continues to be the ATA RAID card to beat in RAID 5.
