Looks good. How is it supported in FreeBSD? Does the package include FreeBSD
drivers and utilities?

Subject: RE: 3Ware Escalade vs. Adaptec 2400A - test results
Here are the results of a quick test of the Adaptec 2400A vs 3Ware 7xxx
Series.
I have 4 x Western Digital WD100BB 100Gb Drives connected to an Adaptec
2400A controller
with 32Mb of cache setup as a Raid5 volume.
Using a simple script to generate a 1Gb file and read it back, I filled
the disk completely.
From the logs it generated:
64Kb Stripe size:
Pass 6 - 1048576 kb written in 89 seconds, at 11781 kb/Sec
Pass 6 - 1048576 kb read in 35 seconds, at 29959 kb/Sec
Pass 7 - 1048576 kb written in 88 seconds, at 11915 kb/Sec
Pass 7 - 1048576 kb read in 36 seconds, at 29127 kb/Sec
256Kb Stripe size:
Pass 6 - 1048576 kb written in 84 seconds, at 12483 kb/Sec
Pass 6 - 1048576 kb read in 42 seconds, at 24966 kb/Sec
Pass 7 - 1048576 kb written in 84 seconds, at 12483 kb/Sec
Pass 7 - 1048576 kb read in 43 seconds, at 24385 kb/Sec
And the 3Ware in Raid5 using 8 disks, 64k Stripe size:
Pass 23 - 1048576 kb written in 115 seconds, at 9118 kb/Sec
Pass 23 - 1048576 kb read in 15 seconds, at 69905 kb/Sec
Pass 24 - 1048576 kb written in 116 seconds, at 9039 kb/Sec
Pass 24 - 1048576 kb read in 15 seconds, at 69905 kb/Sec
Not really a straight comparison as the 3Ware has more spindles, but
that's as quick as it goes.
Iozone reckons:
File size set to 10240 KB
Time Resolution = 0.000005 seconds.
Processor cache size set to 1024 Kbytes.
Processor cache line size set to 32 bytes.
File stride size set to 17 * record size.

It's a damn shame about 3Ware.
