New LSI 9200 series controllers: 6Gb/s, 2.88 GB/s seq. reads, 1.87 GB/s seq. writes

[F.E.A.R.]

I think the array expanding goes at about 4MB/s on my 3ware 9650 and I believe it was about 12MB/sec on Adaptec 5405... so you do the math.
I don't thing we are talking hours here.
Remember it is HEAVY disk trashing during this

It made me invest a whole lot more, and go for 8 drives at once. Didn't want to risk it going wrong in the process.

What???

I expand my Raid 6 from 3TB to 4TB (netto) in only 17h (total time !!!)
The 5805 has more CPU-Power than my 1261-ML, but it´s not faster.
A consistence-check takes 3:15h (326MB/s.)


@ all

SAS-HBAs are optimized for SAS-Drives. Areca SAS-HBAs simulate the SATA-Protocoll only with software. I think all other controllers too!?


@ Tiltevros

Areca´s ARC-12xx-Series (IOP341) is old, but fast with little files.
60.000 IOps @ 512Byte and 0,02ms in HDtune - Random Access is no problem.

We need more realworld-benches.
