Pros: This SSD is 7mm high which is good for my Lenovo X220 tablet. This harddrive is even larger than the conventional hard drive in the same size, which is 512GB maximum (7mm high, 2.5 inch hard drive).

Cons: It is expensive. But considering the high speed and therefore high efficiency this bring, it is worth the money.

Pros: I use this enclosure with a Hitachi Utrastar 7K3000 3TB, 7200rpm hard drive. When it is recognized (after the procedure descibed below), the speed at USB 3 and USB 2 connection are as expected.

Cons: I connect it through either USB 2 and USB 3 port of my computer. In both cases, the computer CANNOT recognize the hard drive unles I am doing the following. I have to turn on the hard drive, wait for around 5 minutes, disconnect the USB cable and reconnect it again, then the computer will recognize the hard drive.

Overall Review: It seems to me this is the problem of the enclosure. My computer is Lenovo X220 Tablet purchased recently with SSD drive. For USB 3 connection, I connect the drive through express card USB3 adaptor. For USB 2 connection, I connect the drive throrugh the USB 2 port in the docking station.

Pros: Very fast and the largest size for mSATA size as I am aware of. I used this one to replace my 128GB mSATA SSD drive in my ThinkPad X220 Tablet. I have purchased separately a USB enclosure for my old 128GB mSATA drive so that it becomes a portable hard drive.

Cons: Really no considering the small physical size and large volume for $200.

Pros: I put this SSD into the PCI Express Mini Card slot in Lenovo X220. In this way, I can have a very fast system drive. I divided into 58GB for C drive (running Windows 7) and the rest 58GB for data that use often, especially the outlook pst files. The regular hard drive slot of X220 can be 1 512GB rotional hard drive or an Intel 600GB SSD drive. In this way, we can have basically two hard drives.

Cons: It is not a con for the mSATA drive. I have to ask my technical support person to reinstall Windows 7 from scratch in my X220 as I read from somewhere in the web to do so. Lenovo should come up a solution for this system configuration.

Overall Review: I read from the web some problem with SSD drive. I think these problems happen in esktop or server application where it is possible for a sudden power loss. For notebook computer application, this is not an issue since we will have power all the time (battery powered).

Pros: Largest size in 2.5in form factor

Cons: Not reliable. I put the hard drive into a reliable enclosure which I have purchased several units before. When I am transferring data from computer to this harddrive, it dies. Later on, I tried to place the hard disk into different enclusores, the computer cannot recognize the hard drive either. In addition, I can hear clicking sound from the hard drive. I have even connect a 5V power into the enclosure (one connection throrugh USB 2 and another connection through USB 2 power connection).
