Review on 🔒 StarTech.com M.2 SSD Aluminum Enclosure - USB 3.0 (5Gbps) with UASP - M.2 NGFF SATA (B Key & B+M Key) - Portable External Enclosure (SM2NGFFMBU33) by Nick Atkinson

As of June 2017, this is the only review of dual SATA M.2 enclosures. sights below. It comes with two USB cables, a Type-A to Micro USB 3.0 and a Type-C to Micro USB 3.0. When I tested the drive on my USB 3.0 (USB 3.1 Gen 1) port, there was no problem transferring a 10GB video file to and from the drive. When I tested the drive on my USB 3.1 Gen 2 port, it got stuck in the middle of transferring the same 10GB video file. I solved it by changing the cable to a USB Type-C cable and connector. I'm not sure why this works with Type-C and not Type-A, but I digress. My computer has the following specifications: Windows 7 Pro x64 with Intel Core i7 4770k SP1 (at 4.0 GHz) Asus Maximus VI Hero with Z87 chipset 32 GB DDR3 memory (at 800 MHz) Samsung 840 hard drive Pro 512 GB - SATA- III 4x native USB 3.0 ports Startech USB 3.1 Gen 2 PCIe card (1 x USB Type-A port - 1 x USB Type-C port) This enclosure supports 2 x WD Blue M.2 SATA drives with 500GB each in RAID 0 This card appears to be using a SATA-III to USB 3.1 Gen 2 interface. Obviously you're limited to the speed of the SATA interface, which is 6Gbps and not the 10Gbps that the USB 3.1 Gen 2 standard is capable of. That is, if you're judging by benchmarks. I figured since it's a RAID it might use a separate pipeline for each drive and be able to use the full 10Gbps speed, but that doesn't seem to be the case. I also tested a USB 3.0 drive and got the same speed as two drives in RAID 0. This means that if you only have one USB 3.0 (USB 3.1 Gen 1) slot, you will not see any benefit from using 2x drives. , in this case choose a single drive enclosure. If you have a USB 3.1 Gen 2 port, you will see speedup when running RAID. Pros: Fast Includes required screws Includes 2 cables Supports RAID 0/RAID 1/JBOD/BIG Makes TRIM Sturdy aluminum construction Cheaper than Sandisk Extreme 900 and probably just as fast Cons: Blocks with Type-A cable but works with Type-C too USB 3.1 Gen 2 cable In summary, I'm happy with the speed I'm getting and I love this case. If you have a USB 3.1 Gen 2 port and want maximum speed when using two drives in RAID 0, I would definitely recommend this enclosure. If you have USB 3.0, use the same enclosure and drive. Note. It includes all screws needed to install and cover two M.2 drives plus 1 extra screw.
