This particular NVMe PCIe drive advertises it works with PCIe 3.0 x4, but various sites report it works on PCIe 2.0 (at a somewhat reduced speed, but still fast).
The Precision T5500 has only PCIe 2.0 slots.
Without a great deal of understanding of specific kinds of PCIe slots, is there hope of plugging one of these NVMe drives into the Precision T5500 and booting from it?
Though the drive may indeed work, the system will not be able to boot from it. Booting from NVMe generally requires a very new (2016 oldest) system with a very new UEFI setup routine.
Thanks to both of you. The adapter wouldn't be a problem, but inability to boot because of the BIOS throws my whole idea for incremental improvement off.
I already have a PCIe controller rocking 8 SATA III SSDs. Throughput is in the ballpark with the NVMe drive and actually very good, but the reduced latency of the NVMe stack would speed up small I/O operations enough more that it would make the system capable of even better overall performance. My ATTO 4K numbers are only in the vicinity of 125 MB/sec.
I will plan to boot from one of these NVMe cards in my next new workstation build, and have the RAID array serve data.
