    As of June 2017, this is the only review of the Dual SATA M.2 Enclosure.
    4 Stars
    As of June 2017, this is the only review of the Dual SATA M.2 Enclosure.
    As of June 2017, this is the only review of the Dual SATA M.2 Enclosure. Benchmarks below. It comes with 2 USB cables, one with a Type-A to Micro USB 3.0 and one with a Type-C to Micro USB 3.0. When I tested the drive on my USB 3.0 port (USB 3.1 Gen 1), there was no problem transfering a 10GB video file to and from the drive. When I tested the drive on my USB 3.1 Gen 2 port it would freeze in the middle of a file transfer of the same 10GB video file. I resolved this by switching the cable to the USB Type-C cable and port. Not sure why it works with the Type-C and not the Type-A, but I digress. My PC has the following specs: Windows 7 Pro x64 w/SP1 Intel Core i7 4770k Processor (Running @ 4.0GHZ) Asus Maximus VI Hero w/Z87 Chipset 32GB DDR3 Memory (Running @ 800MHZ) Samsung 840 Pro 512GB Hard Drive - SATA-III 4x Native USB 3.0 Ports Startech USB 3.1 Gen 2 PCIe Card (1x USB Type-A Port - 1x USB Type-C Port) This enclosure 2x WD Blue M.2 SATA Drives 500GB Each in RAID 0 It appears that this card is using a SATA-III to USB 3.1 Gen 2 interface. Apparently you are limited to the speed of the SATA interface which is 6Gbps and not the 10Gbps the USB 3.1 Gen 2 standard is capable of. This is from judging by the benchmark speeds. I thought possibly since it was RAID it would use a seperate pipeline for each drive and be capable of using the full 10Gbps speed, but that doesn't appear to be the case. I also benchmarked one drive alone with USB 3.0 and got the same speed when I benchmarked two drives in RAID 0. This means if you only have a USB 3.0(USB 3.1 Gen 1) slot then you will not see any advantage by running 2x drives, go for the single drive enclosure in that instance. If you have USB 3.1 Gen 2 port then you will see a speed bump by running a RAID. Pros: Fast Includes Necessary Screws Includes 2x Cables Does RAID 0 / RAID 1 / JBOD / BIG Does TRIM Sturdy Aluminum Construction Cheaper Than A Sandisk Extreme 900 & Probably Just As Fast Cons: Locks up with the Type-A cable but works with the Type-C cable on USB 3.1 Gen 2 In conclusion, I am satisfied with the speed I am getting and I do like this enclosure. If you have a USB 3.1 Gen 2 Port and are looking for top speed using 2x drives in RAID 0, I would definitely recommend this enclosure. If you have USB 3.0 go with the single enclosure and drive. Note: It includes all of the screws necessary to install 2x M.2 drives and to keep it closed plus 1 extra screw.

    5.0 out of 5 stars If You Need M.2 External This Is It
    Reviewed in the United States on November 14, 2017
    Style: USB-ASize: M.2 SATAVerified Purchase
    Did exactly what I needed. I had an m.2 256GB Sata SSD (Micron 1100) that originally came with a laptop I put a Samsung Evo 960 500GB m.2 NVMe PCIe drive in. It was just sitting around and I was considering getting a SD card for another laptop, but the SD wouldnt be fast enough (write) for what I needed.

    This is smaller than an external pre-bought drive and based on the drive in it much faster than any SD card. Using this with a Dell i5379-5893GRY-PUS laptop and it works perfectly (granted im using Manjaro KDE Linux). Benchmarked the drive is doing about 450MB/s read and 400MB/s writes, which is what I expected to see from the specific drive I was using.

    The enclosure itself was well packaged, came with all the screws and a small screw driver along with the USB type A to B cable which is about 1ft long. Install was easy and once assembled seems very sturdy and well made.

    It does have a small indicator light on the end with the USB port, which is white in color and blinks on activity.

    I am very happy with it as I was able to take a SSD I had no other use for and turn it into a very fast, reasonably small external drive that wouldnt be a burden to carry around with the laptop while traveling.

    I primarily use it for KVM VM images/files that I do not use frequently. It worked perfectly for this letting me install Windows 10 within a VM in about 5 mins.

    5.0 out of 5 stars Well made, easy to use and very very fast!
    Reviewed in the United States on April 17, 2017
    Style: USB-ASize: M.2 SATAVerified Purchase
    I bought the M.2 version to house a 2280 M.2 SSD I had spare after an upgrade. The enclosure is a well made and thick aluminium which feels solid but not heavy in the hand. The sides of the enclosure are well vented, and between the metal case and ventillation I feel confident that my drive will be kept a cool enough to last as long a as the manufacturer intended.

    Installing the SSD is forward and fast. Removing two small screws from the end cap was all that was needed to insert the drive, and no other screws or clips are needed to secure the drive once the end cap is replaced. With the end cap screwed back in you're done! It could hardly be easier.

    The USB 3 A to USB 3 Micro B cable provided is of fine quality and I had no trouble getting excellent drive perfomance from the supplied components. The cable feels well made and has lasted several months of moderate use without any sign of degradation.

    The end result is by far the fastest USB memory stick I've ever used, though it's also physically the largest.
    Carrying the cable around with the drive is less convenient than a typical USB memory stick, but with the size of the unit I don't see any way to get around the need for a cable. I think that making the USB 3 micro B connector a right-angle connector, and fitting clips down one side of the case to hold the cable when not in use would be the only improvements I can think of.

    Well made little gadget that works fine. There are two caveats. The USB plug male does not easily plug in as the construction is off by a hair. Second and finally the supplied standoff to attach the M.2 drive doesn't work with the drive I ordered: ADATA SU800 256GB M.2 2280 SATA 3D NAND Internal SSD (ASU800NS38-256GT-C). The screw is not long enough to accomadate the drive so no way to attach it so I used electrical tape to hold the drive down. The screws etc are VERY small so be careful.

    I put two Teamgroup MS30 1TB drives in the case and set it up for RAID-1. Windows 10 found it right away and loaded the driver. After formatting it exFAT (better for external drives than NTFS), I did some file transfers using a 10 gig folder with thousands of different files.
    Using the USB 3.2 Gen-1 port on my laptop, the speeds were painfully slow. It would really slow down on certain file types like Excel spreadsheets. After 10 minutes it was around 30% done and I gave up.
    Switching the cable and going through a Thunderbolt 4 port, man what a difference. It literally took 2 minutes to move all the files. Certainly not blazing speeds but good enough for my backup needs.
    Hopefully it's reliable.

    I don't know what the odds are, but I was hoping I'd get a good one. I'll try another vendor and hope for the best. These things are hit and miss, for sure. Manufacturing quality control is marginal, at best.

    For those interested in more detail, I already have some formatted, known good M.2 SATA SSDs (     Samsung 850 EVO 120 GB M.2 3.5-Inch SSD (MZ-N5E120BW)  and  Transcend Information 512GB SATA III 6Gb/s MTS400 42 mm M.2 SSD Solid State Drive (TS512GMTS400) ). This enclosure didn't work with any of them (this is on a Macbook Pro with USB 3.0 ports). They work fine in other enclosures. I used a known good cable, too, to eliminate that possibility, and reseated the cables and SSDs several times to reduce the possibility of a bad connection to the minimum.

    I did notice what looked like some sloppy (too much) solder at each end of the M.2 connector. And, at one point, my Macbook complained of overcurrent on the USB port and disabled it (it returned fine when I unplugged the enclosure). the ASMedia controller did appear on the USB bus as displayed in the System Report in About This Mac, but I never saw the drive.

    It's a bit disappointing, because this enclosure has a nice "feel" (all metal with good ventilation), and I had really hoped that it would work. I've liked other StarTech products that I've bought in the past, and will continue to give them a try (for a while, anyway). I'm sure that some percentage of these enclosures are fine, but mine wasn't. It's a data point; I'm not yet at three strikes with StarTech.

    Gut verarbeitet. Funktioniert obwohl die Anleitung hätte besser sein können. Allerdings war der Kundendienst bei Startech sehr hilfsbereit.

    Simple instructions for assembling the device, and if you are careful you can reconfigure it time after time. It would be easy, however, to ruin the device by over tightening the screws. Over all, this is a handy device for a laptop, but also useful for transferring files from one device to another.

    No fue necesario instalar controlador, las computadoras que uso con Windows 8.1 y 10 lo reconocieron inmediatamente.
    Importante: funciona solo con unidades SSD M.2 SATA.
    Fabricado en aluminio de muy buen calidad, incluye desarmador y accesorios de repuesto para cerrar la caja.
