PROMISE EX4650 + 4x FUJITSU MBA3300RC
 
Test Results
Here we go with the
all-important test results:
Promise EX4650 + 4x Fujitsu
MBA3300RC in RAID-0, 64k stripe
HD Tach v3.0.1.0, 8MB Zones
Promise EX4650 + 4x Fujitsu MBA3300RC in RAID-0, 64k
stripe
HD Tach v3.0.1.0, 32MB Zones
Promise EX4650 + 4x Fujitsu MBA3300RC in RAID-0, 64k
stripe
ATTO Disk Benchmark
Promise EX4650 + 4x Fujitsu MBA3300RC in RAID-0,
1024k stripe
HD Tach v3.0.1.0, 8MB Zones
Promise EX4650 + 4x Fujitsu MBA3300RC in RAID-0,
1024k stripe
HD Tach v3.0.1.0, 32MB Zones
Promise EX4650 + 4x Fujitsu MBA3300RC in RAID-0,
1024k stripe
ATTO Disk Benchmark
The bigger 1MB stripe
size improved read speeds quite noticeably.
Impressive either way!
Promise EX4650 + 4x Fujitsu MBA3300RC in RAID-1E,
64k stripe
HD Tach v3.0.1.0, 8MB Zones
Promise EX4650 + 4x Fujitsu MBA3300RC in RAID-1E,
64k stripe
HD Tach v3.0.1.0, 32MB Zones
Promise EX4650 + 4x Fujitsu MBA3300RC in RAID-1E,
64k stripe
ATTO Disk Benchmark
Wow, for a RAID-1E
array, that's actually not too bad. I think
the controller is reading from more than one disk,
but still struggles (as others do) writing to all
the disks at the same time.
Promise EX4650 + 4x Fujitsu MBA3300RC in RAID-5, 64k
stripe
HD Tach v3.0.1.0, 8MB Zones
Promise EX4650 + 4x Fujitsu MBA3300RC in RAID-5, 64k

RAID-5 is better than
RAID-1E, but write speeds still drastically lower
than reads.
Promise EX4650 + 4x Fujitsu MBA3300RC in RAID-6, 64k
stripe
HD Tach v3.0.1.0, 8MB Zones
Promise EX4650 + 4x Fujitsu MBA3300RC in RAID-6, 64k

Changing the array to a
RAID-6 makes writes plummet further.
Promise EX4650 + 4x Fujitsu MBA3300RC in RAID-10,
64k stripe
HD Tach v3.0.1.0, 8MB Zones
Promise EX4650 + 4x Fujitsu MBA3300RC in RAID-10,
64k stripe

1024k stripe
ATTO Disk Benchmark
Lastly in RAID-10
arrays, we get a better balance of writes and reads.
But then again, it's RAID-10...
