Pros: Is in JBOD so any micro sd is compatible no matter what size

Cons: Extremely frustrating to troubleshoot if it doesn't work out of the box.

Other Thoughts: if it isnt working out of the box then go to device manager and delete the current driver for it, and search automatically for the best one. this worked for me.

Pros: I have nothing positive to say about this product for the face that since I had it it has yet to work properly or at all.

Cons: It does not pick up with almost any of my external usb cases or connections regardless if its a 2.0 usb or 3.0 usb connector or internally in my mac or pc via data connection. When it does pick up under disk utility I can see that it has a RAID set but when I attempt to Initialize the disk it always fail on my mac and the same goes for my PC.

Other Thoughts: Do not waste your hard earned money because chances are it will not work. Many reviewer show that they are also having the same difficulties with this product that I have and so will you. I know it may be very tempting to take the chance because in theory it would be an awesome device if it actually worked.

Pros: Inexpensive way to use one, two or four micro SD cards as if they were a SSD.
Readily fits standard 2.5" bays and enclosures.
Well positioned mounting screw holes.

If you already have a number of equally sized microSD cards, then this adapter would be a great way to put them to good use instead of just sitting in a drawer somewhere.

Cons: It doesn't actually work.
I tried installing it on two machines:
Gigabyte Z87X-UD5H, Intel i7-4770K, 16 GB Ram, Windows 10 Enterprise.
XFX nForce 780i SLI, Intel Core 2 Duo E8400, 8 GB Ram. No OS. Tried installing Windows 7 Professional and also Ubuntu 14.04.1 Server.

On both machines, the BIOS would correctly identify the adapter and the amount of memory in it. But, under Windows, the OS would simply fail to partition the drive. When it appeared to succeed, it would fail to format.

Ubuntu installer seemed to have better luck. It would complete the OS installation, but the machine was unable to boot.

I tried with just one card (in the J1 slot), two cards (J1+J2) and all four cards. The results were always the same.

I did discover something interesting. Even though the manufacturer claims that the adapter has integrated RAID 0 function, it appears this is not accurate. I may actually implement JBOD instead.
The reason is that, when I moved from one 8GB card (in J1) to four cards under Ubuntu, the partition step of the installation reported that there was already a 7GB partition and a 1 GB partition, plus an additional 20 GB of free space. I had indeed setup these partitions when using just one card, but if the controller implements RAID 0 automatically, the installer should not have detected the prior installation partitions.

I've reached out to Syba tech support but thus far no response. Although I'm not sure what they would recommend I do that I haven't already tried.

Other Thoughts: This product is NOT a replacement for an SSD. It is not a replacement for a modern mechanical hard drive either.

If the claimed integrated RAID 0 function worked, you would get up to four times the speed rating of the cards you add to the adapter. However, because the interface is SATA I, it tops out at a maximum of 150 MB/s. Modern mechanical drives easily reach and, in some instances, surpass 150 MB/s. Not to mention SSD which are faster than 250 MB/s.

You should look at this product as a way to put unused microSD cards to work.
It may also be a good fit for routers and other machines which don't see much I/O and don't require much space.

I wish this product had worked, I've got a few identical microSD and SD cards just sitting.
I own other Syba products and have not had problems before.

Pros: Inexpensive SSD, form factor.

Cons: Syba product description, and Syba tech reps, were not very clear on what size/type SD cards this takes. They said it was tested with 16GB cards. I've got two 32GB microSDHC class 10 cards in it, and they work fine.

Manufacturer Response:

Dear Customer,

Changes have been made to the description.

We apologize for the confusion made from a previous product listing with a similar model.

Thank you for purchasing one of our products, and for leaving us your valuable feedback.
