Precision 3450 SFF : anyone using the 3 M.2 2280 slots for SDDs ?

According to this Dell spec sheet, that should be fine with your 11th Gen CPU. The specs are 3 x M.2 PCIe SSD with an 11th Gen CPU and 2 x PCIe M.2 SSD with a Gen 10 CPU. You notice the label on SSD 2 which specifies that limitation.

As for the BIOS question, SSD 0 would more than likely be the slot to use for the boot drive.

Before taking the plunge and purchasing another Gen 4 drive, move one of your (data) drive to that slot to test for functionality.

Without dwelling deep into the technology, check your system if the following specs may applied, Xeon CPU can provide more PCIe lane (40) than a Core-i CPU (20), while the slots (PCIe, M.2) wired to CPU compatible with gen 4 (graphics, nvme) performance, devices connected to chipset are limited to gen 3.  Theoretically, a gen 4 nvme drive can get x2 the transfer speed over a gen 3 nvme, so is more in cost.  With that said,  if the intended slot can't perform at gen 4 speed, why spending extra without gaining the performance.

Yes, I did that and it works.

According the specs I know I'm all good.

I was hoping someone had already done it and had experience with it. You never know, performance issues etc.
