I switch to i5-6400t with motherboard GA-H110M-S2H.... I jump to 30/50W but at least it will work like I want. I am right now between 20 and 35W but too slow. Do you think this time I do a better choice ? I think I can really use the 20$ I invested in my legit (or not hahaha) lsi card to really mulitplex my 2.5 slow hard disks edit; I have returned to amazon my 23$ pciex1 sata card....

hum... I think I found the issue... my fucking motherboard asrock j4105M as a pcie 2.0 x16 port running at x1 speed !!!! this situation is just crazy !!! https://www.asrock.com/MB/Intel/J4105M/index.asp again a new return to amazon pff

..... seriously.... lol.... what can I do ? there is a setting somewhere? never seen that before.

I see 8 disks, with speed from 130 -> 60. So the average I imagine should be around 85/90. Still don't understand why parity check cap at 55MB/s. I have also included history of parity check. The 63MB/s was prior the LSI card installation (2 parity drives onboard SATA + 6 sata disk on pcie x1 card). 53MB/s is with all disks on LSI SAS 2008. 1 parity drive on port1, 1 parity drive on port0.

How can I test the link speed with the controller? I have check my MB bios, and force pcie 2.0 for the slot... in case of. Nothing change with AUTO mode. I have also disable ASPM? benchmarks are running.

another information, maybe relevant... during dd tests, write speed vary depending on where data is written on disk..... 130 to 70MB/s. read don't... always 50MB/s... even when I read the file written during the write test at 130MB/s for example. of course I do write and read tests on /mnt/disk[1-6] to not use my cache. I don't use a sata cache SDD drive but a pcie card with nvme SDD, which is far more efficient than the sata version... I would never go back on a sata sdd cache drive anymore !!!!

I have just upgrade my conf with a lsi sas 2008 and I can't figure out why read performance are worst with the LSI than with SATA. I have a LSI 9220-8i, H3-25113-03A. Write performance are better, for example if I do a dd test, write performs 30 to 40% faster. (tests done on the same drive). On my old 2.5 1T drive, I can reach more 130MB/s write speed at the beginning of the disk and around 70MB/s at the end. It was not possible to reach this level of performance with my sata card on regular load. With my sata card, I was able to have this kind of performance if I turn off all dockers and VM. But read performances are stuck at 50MB/s max.... on ALL drives. This is the first time I see disks faster during write than read. For example, if I do a parity check, I am stuck around 50MB/s because read is done at this speed. If I use my onboard sata (for parity disks) and pci sata 6x ports (for data disks), parity check is done at 65MB/s. please help. BTW, I have flash the latest firmware P20 yesterday, nothing changed. I have bought this card on ebay, from a seller with thousands of positive feedbacks. the card was delivered with the firmware 10.x.x.x Any idea where I can investigate?
