I can't update firmware on S2500.
I tried toolbox 3.3.3 and 3.3.4
The actual firmware is RG20.
There is 2 SSD S2500 in RAID1.
Booth drives show a fast degradation at 83% (within 1 year and low usage 1.7Tb)
Same issue with both drives.
I believe you cannot do a firmware update while the drives are in RAID. Can you try to https://downloadcenter.intel.com/download/18363/Intel-SSD-Firmware-Update-Tool Download Intel® SSD Firmware Update Tool
If you then create a CD or USB drive and switch to AHCI in the bios (No RAID) and boot to the Firmware update tool, You'll likely be able to update.
Please remember to enable RAID again before booting the operating system.
Note: there is some risk here if the system is using RAID 0 and the system accidentally boots to the drives while in AHCI.
I already update a firmware on drives in RAID1, without problem.
There are 2 things in this case. The firmware issue and a very fast degradation of the drives; both à 83% in 1 year, with a small use of the drive.
Could you please download the latest version of the Intel® Solid State Drive Toolbox and let us know if the error still shows up?

As a follow up, now the drives are at 73% wear out, and one drive just fail.
All the S2500 that I sold, show a premature wear out %.
I guess that they will fail soon like the 320 series.
It seems the drives keep dropping the wear out level, this basically goes directly with the workload you put on the drive; however, this is dropping fast.
