The answer here depends on the specific model of server being used. I was holding off until the OP could describe the actual server being used, as the SSD options vary. Read through the descriptions of HP's SSD portfolio for detailed information on the different classes of drive. For instance, with a G6 or G7 ProLiant, all SSD performance will be ...

The HP Solid State Drives (SSD) Quickspecs document likely has all the details you need. Besides raw speed and IOPS a large part in price difference between what HP calls Value Endurance, Mainstream Endurance and Enterprise Performance is how often the complete disk can be overwritten, because flash supports only a limited number of write cycles. I ...

I found the technical specs on insight for the HP drives: Specfications -> Performance -> 4KB Random Read 63000 IOPS 4KB Random Write 19200 IOPS Drive Transfer Rate 600 MBps (external) Internal Data Rate 480 MBps (read) / 185 MBps (write) I then looked up the Samsung Evo 840 specs, this case taken from [ebuyer], this case a 120GB ...

Did you repeat this, perhaps multiple times? Since read performance is not impacted at all, I'd suspect slow write performance of the "failed" SSD due to insufficient free (trimmed) FLASH blocks. Every RAID-rebuild does a full write to the newly added device, thus writing large amounts of data and depleting the target device of pre-erased blocks. From ...

I bought 6 of the 1.2tb cards in the last couple months. One of them has already failed. So I would absolutely raid them. I used windows active disk mirror. The drive failed with the message "missing LEB map". I was told it would need to be swapped out. But to get the RMA approved I would need to take pictures on both sides of the failed card (requiring a ...

I think you are just reading the manual too literally. With the exception of the list of devices I don't believe any of the brackets go in the actual command. Your command should be something like this MegaCli -SecureErase Start Simple -PhysDrv [252:0,252:1] -a0 (You may need to escape the remaining brackets depending on your shell.)
