Try SSD MX300 + LSI-9260-4i in RAID 10

jazz1611

Hello,

Did anyone have try 4 SSDs Crucial MX300 500GB vs LSI-9260-4i in RAID 10? I have some search with result poor performance I/O. Please let me know. Thanks.

I tested it before gives around 800MB/s

Maybe the LSI 9620 take low performance I/O (ex: bottleneck the I/O). But that speed is can accept. Thank you.

I used LSI 9260 -4i

We're observing pretty bad results with this SSDs. A little bit disapointed. Not with 9260, though.

Is that enterprise grade ssd or consumer?

Good question!

Consumer and so shouldn't really be used with RAID Controller.

Not only consumer SSD, but very cheap consumer SSD. I would never use SSD with TLC-NANDs for anything serious. Performance degradation is very severe, especially when TRIM can not be used (as it is with raid-controllers for anything except raid0)...

Praise these two members @Clouvider @Jarry . @jazz1611 dont say that you weren't informed. You are on a path for disaster.

@Hxxx @Clouvider @Jarry @jazz1611 It depends how you use it, I have read it has an endurance rating of up to 220TB. So if you use it in a 8 drive RAID 10 configuration it should last at least 3 years.

Nah, not supported by the controller. Can lead to interesting things like random rebuilds, disks disappearing from the array etc. You simply don't use it that way.

It's not tested, not supposed to work according to the controller manufacture, and if it breaks, you're on your own, so say good bye to your data.

Sorry, didn't see it was a hardware raid card... I saw a test a few month ago with the LSI 3008 (software raid) and 8 MX300 SSD drives which performed very well.
