3Ware Escalade 7410
  July 3, 2001 Author: Terry Baranski  

The Benchmarks...

The following tests were run with the card's write cache setting enabled and a stripe size of 64k. Driver version 1.10.01.032 was used along with BIOS release 7.1.1.

WinBench Results...

Let's begin with single-drive scores to use as a baseline.

No big surprises here... The 7410's access time is reported somewhat higher relative to the 6400, though one can not draw any conclusions from this.

The 7410's RAID 0 Diskmark scores come in lower than that of a single drive, something that obviously doesn't reflect reality. Unfortunately, issues with WinBench's Diskmark tests continue with the Escalade 7410. As we'll see, the Diskmark results for all RAID levels are clearly unrepresentative - we'll refrain from commenting on them further.

The adapter's sustained transfer rate is very impressive, as was the 6400's. There's no doubt that the 107MB/sec "limitation" is caused by the PCI bus (the testbed's motherboard contains only 32-bit/33MHz slots) as opposed to the card itself.

WinBench RAID 1 Scores...

Two things are notable about the 7410's RAID 1 WinBench scores, both echoing the unit's predecessor. First, the 7410's RAID 1 access time clocks in about 2ms lower than a single-drive configuration. This indicates that the adapter load balances linear reads based on which drive's read/write head is closer to the requested data. Second, the 7410's RAID 1 STR is significantly higher than that of a single drive configuration. This is TwinStor in action.

WinBench RAID 10 Scores...

The 7410's RAID 10 access time matches that of a single drive configuration. This is interesting as it suggests that TwinStor isn't load balancing linear reads in RAID 10 like it does in RAID 1. We're at a loss as to why this is the case considering that the Escalade 6400 appears to balance such reads.

Access time remains about the same, while STR increases as one would expect.
