Sandisk Optimus Eco SDLKOC6R800G5CA1 SAS2 DRIVE ssd

[Computerman109]

Good day
First off thank you to all that are willing to share your experience with sas drives in general.
The question I have is for a Sandisk Optimus Eco SDLKOC6R800G5CA1 SAS2 DRIVE ssd.
Being new to the sas drive world I've run into a problem.
The drive is connected to a Dell t7610 tower with the LSI 2308 sas2 controller
The at best read speed is 127MBs and write 121MBs.
I have tried 2 different programs Crystal Mark and As SSD with very close readings.
I have other SSD's PNY Samsung ect that get number way over 530 MBs read and write and be mindful that those are sata3.
The question is why is this drive slow
Is there a seup that I'm missing.
I did try the drive on different sas2 ports and the problem remains.
Updated the firmware problem remains.

Any and all suggestions are welcome

Thank You
Jason

It is a nice drive, but unless it is on the Dell certified list, good luck getting any real help from the usual channels.

Anyway, Personally I would buy a better controller.

Is the 2308 on a card or is it chip on Mainboard? If card which card, and do you know if it has cache? Usually if there is no RAID 5 option there is no cache

which firmware did you flash, IR or IT version?

some specs for different cards here for reference https://www.servethehome.com/lsi-sas-2308-raid-controller-hba-information-listing/

the "solution" here may be a little enlightening as well.
