Adaptec 6405 vs LSI 9260-4i
Hello,
We have 4 Samsung 840 Pro and we want it for RAID10 array.
What you suggest? Adaptec 6405 or LSI 9260-4i for performance?
Currently we have Adaptec 6405 and and the dd test gives :
root@cronus [/]# dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync
16384+0 records in
16384+0 records out
1073741824 bytes (1.1 GB) copied, 2.86553 s, 375 MB/s
do you believe that the LSI 9260-4i have better performance with samsung 840 pro?

Controllers does not support TRIM and you will burn the SSDs really fast.
Use software Raid-10 and you will get a great performance.█ QHoster.com - Web Hosting with DDoS Protection | Shared & Reseller in Europe/North America

MDADM + AHIC works great with ssds. Make sure your mobo has 6Gb/s ports

Get the LSI 9271 with FastPath, it will increase SSD performance by 3x as much as right now.

Again raid cards do not support TRIM. TRIM is working directly with the SSDs. In intensive write operations server and using MLC drives you will exhaust them really quick. If you are using Software raid you will be a lot better. Modern CPUs are really powerful and do not slow down with Software raid.

We never used so many SSDs in raid. See Samsung specs for the smallest 128GB SSD 840 Pro:
Up to 530MB/sec Sequential Read* Performance may vary based on system hardware & configuration
Up to 390MB/sec Sequential Write* Performance may vary based on system hardware & configuration
So something is wrong you should have at least 600MB.s writes.█ QHoster.com - Web Hosting with DDoS Protection | Shared & Reseller in Europe/North America

It is, while I don't have the exact statistics written down I can say that once we enabled fast path on a clients heavily database driven site that was using 4 x Intel 520's in Raid-10 we saw a good amount of IO wait reduce. I don't think its something that can be calculated by write/read or performance tests since from what I understand FastPath just helps improve routes of similar and frequent r/w's. LSI's website is what claims to increase speeds by x3 but I am not exactly sure if that is accurate or not, I do think in the right server though it holds it's worth.

Linux RAID doesn't support TRIM either. In fact, TRIM isn't a 'good thing' with typical server workloads either. Over provision is the answer if you're concerned with wearing.
