Hello artiman73,   I tried to drill down on these Sales SKU:  400-AXPB and 400-AZPH but it did not give me a useable 5 digit part number.   Referencing the Dell PowerVault ME5 Series Storage System Support Matrix [URL]   I was able to find  a 1.9T and 1.6T:   Part #:D4VFW Part Desc.:SSDR,1.9T,2E,IS12,2.5,S-LBP,EC SSD, 1.92TB, 2.5, 512e, SAS, 12Gbps,ISE, STX, LangeBP Mainstream SAS, EC   Part #:GD3N0 Part Desc.:SSDR,1.6T,2E,IS12,2.5,X,P63,EC SSD, 1.6TB, 2.5, 512e, SAS, 12Gbps,ISE,Kioxia, PM6, EC   If neither of those are what you are looking for I would recommend contacting Sales and they could quote you on compatible drives.
I'm trying to understand the differences in terms of R/W IOps and  life span in TB for the following SSD options available in ME storage. I haven't been able to find the tech specs GF82IO4:   1.92TB SSD SAS ISE Read Intensive 12Gbps 512 2.5in Hot-plug AG DriveGL62XHQ:   1.6TB SSD SAS ISE Mix Use 12Gbps 512 2.5in Hot-plug AG Drive, 3 DWPD, Thanks in advance for your help, Andy
