I have been unsuccessful in getting support from Dell on installing this, so I am turning to the community for help.

I actually did a bunch cause it I was a bit bored at work. I did a Sandisk Extreme 64GB, Sandisk Ultra Flare 32GB, Samsung EVO 850 1TB 2.5", Intel SSD Pro 2500 256GB SATA too. Yeah, thats pretty similar to the bench I did in the enclosure. Though for time I limited the run to 3 instead of 5. NOTE:Even though Dell Hosted Images have USB3 drivers slip streamed in, they may not include the IRST driver (also known as the F6 driver). As a result, the IRST driver must be applied manually during the Windows install process.M3X3 screw(most computers include these. These secure the Y1WJX M.2 drive carrier, or a 2.5" drive into 745TM) Of all three the Shinestar M.2 was the hottest enclosure. Even just sitting idle the enclosure was uncomfortably hot to the touch. It also suffered from random disconnects and at times would not mount.

Since I finally got these benches done. Here's the comparison of the same drives internally installed vs external. All enclosures had nearly the same speeds. Enough that I wouldn't care one way or the other about it. You are limited to about 1050MB/s read & write for sequential files. The drive you install (Samsung EVO, Intel 760p, etc....) has more impact on the speed than the enclosure does.

They are ideal for write-intensive applications such as medical devices, surveillance systems, and POS terminals. Don't forget that having ultimate external drive performance won't help the source drive be any faster than whatever its interface is limited to. And finally, just to rub salt in the wound, Dell produced this guide for upgrading the storage on your 5820/7820/7920 with the above listed parts even though they apparently have no intention of selling them to you.

I'll be using it as work drives. Storing photo's (also when shooting tethered directly to the drive), transferring footage from camera card to the drive and might ocassionally edit using that drive. The PCIe NVMe SSD drive FlexBay has the physical data and power connector to allow a SATA or SAS drive to be physically installed. However, the FlexBay is only configured to communicate with PCIe NVMe SSDs. SATA or SAS drives installed in this FlexBay will not work due to an incompatibility with the drive controller.
