Jh2399,   The carrier 58CWC is showing as compatible with the T340, and 90% of the systems that it shows as compatible with are 13th generation system, but the T340, T440, T640, and T740 all show the 58CWC drive carrier as compatible as well.  Hope this helps.
Hello, I recently purchased a Dell PowerEdge T340 and the HDD caddy that came with my HDD has the DP/N: 058CWC. To the best of my searching this DP/N corresponds to the 13th generation HDD caddy, and was just looking to verify that this was correct. I couldn't find a DP/N that corresponds to the 14th generation. Do I understand everything properly? Is the T340 compatible with the T330 HDD caddy? Reason being I'm looking to buy a few more, but Dell doesn't offer them as a standalone product, e.g. they only come with drives purchased from Dell, but I've found a Dell certified partner that does sell them. I'm aware of the other issues related to buying a non-dell certified drive, but this post is strictly asking about the DP/N and compatibility. Thanks in advance!
