LSI has seemed to be on the ball with the fixes, with the latest FW it may not be an issue anymore, which is a very positive thing!

"Lurking" Since 1977

I've ran a few tests using ATTO (for sequentials only) on the LSI 9265, w/o caching. (Direct IO, Write Through, No read ahead)
Keep in mind that the V3 is working with compressible data, they are in a "heavily used" state though, several TBs written to each drive w/o any cleaning (no TRIM as they are in raid) for 3-4 months, maybe more.
The m4's are set up in a raid 00 (a span of 2x raid-0) so there are 4x 128GB drives, also in a used state.

The V4's could do with some tuning on reads. (which can be seen in other tests as well, coming later...)

Hardware:
A quick test on FW 1.5 shows that things are looking much better on the Areca 1880IX-16 4G
There was a strange reading in ATTO (at 1KB) but compared to previous tests this is something that's worth playing with.

(the results are cached, the point is that it's working, on earlier fw's it wouldn't finish any benchmark)
I'll play a bit more too see if the ATTO anomaly at 1KB can be reproduced.
edit:
64KB strip size, Volume cache mode -> Write Back

Hardware:
For ATTO, try "Neither" instead of "Overlapped I/O"
Also, try increasing the "Total Length" to 2GB (or whatever is the max allowed)
I'll do some more testing later this week/weekend.
My goal was just to see if it was working, at all

Hardware:
Looks like vertex4 compatibility with areca 1880 might be fixed with F/W 1.5.
Probably needs some time to check out completely but looking ok for the most part so far.
I did have a glitch running Anvil Storage Utility, needed to rerun the read test and then all looks as expected'
These are cache runs - 2xVertex4 128gb F/W 1.5 R0 Areca 1880 4GB on crosshair V formula with 3xcpu Phenom II X2 555 BE @ 4ghz -
For comparison here is cache run - 2xVertex4 128gb F/W 1.5 R0 Areca 1261 2GB on X58 with W3520 @ 4ghz -
Interesting that the Anvil benchmark keeps the name "ARC-1261" when switched from 1261 to 1880 - the array name is maintained as I did not recreate the array just moved the drives from 1261 to 1880
1.5 does NOT fix issue with 1880ix controllers!
The test system would get a timeout error on a reboot. A cold shutdown of the system is the only way to get it to boot properly.
I would not recommend this drive with these controllers. Intel 520, Samsung 830, and Crucial M4 (with current FW) all work flawlessly and fast.
I didn't notice any such issues.
Will retry tonight.
