Is this SMART Error?

You don’t and cross your fingers that it works correctly. I have seen NVMe drives claim to be Version 1.4, but not really sticking to the actual requirements. It isn’t a law they have to follow.
If a SSD does not support SMART Tests, then it is quite old or the company is using old controller chips. Sometimes you get what you pay for. But if it isn’t 1.4 compliant, that doesn’t mean the drive is unreliable, it means you cannot check it. And a SMART Long test is a read only function, so it provides minimal information other than it could read those blocks of data.

I checked and they all seem to be 1.2. I’ve asked their support to see if it supports SMART short and long tests. Maybe its a Dell thingy. I’m not sure.

When benchmark testing, you must know your hardware and how it operates. If you want to test the speeds correctly you need to disable all caching. I don’t know how to do that on Windows, but caching will give you better results when dealing with small files.

For Linux/TrueNAS, you would need to first create a dataset with no compression, then create a large file with random data, larger than your RAM size. I’d prefer twice the size minimum, this way your RAM cannot cache it all, for example, create a file that is 300GB in size and benchmark that operation. It will take time to copy that much data but that is what you want. Then you benchmark reading that same data, and if you wanted, reboot the machine to clear the RAM cache. This would give you accurate throughput. You could use fio for this, but there are a lot of options that must be set correctly, meaning it isn’t the easiest tool to use.

I’m new to fio. Not sure how to test it.

Coming back to original thingy, today i installed the LSI HBA and before i start running SMART test as per your guidance, i need your generous help in determining if my HBA is performing normally cause i see JBOD mode. However, i’m able to see all disks with their serial numbers.

Secondly, i wanted to ask if i can run the SMART test on all the four drives together.

LSI 9400-16i Help

Hello Guys, Just setup my TrueNAS machine to do some disks test. I had a 9400-1i laying (purchased earlier) and i updated the firmware back then. Here’s what i can see at the moment. I’m not sure which profile was flashed as it comes in SAS_SATA and NVMe Mixed version. Secondly, i’m not sure if it is running in IT mode.
