This particular unit consists of 2 parts smaller & bigger ones, at first, one can decide it is not durable and have fast flash and base low memory areas, but later on I will write here about the file systems, durability, and the real control of the unit, anyway it is for you.

The units of this type can be use with 20 other devices. This card marked "micro SDHC Class 4" with the data exhange rate not less than 6, being used in particular for mobiles. When you will find out your hard drive is of one third useful area do not be angry, you can buy external memory flash drives, memory cards now up to 128Gb and more. They are compact and might be considered as a resulting vector of modern technologies.

As I mentioned the adapter is for USB 2.0, but I have device of the lower data-exchange rate 1.2 USB protocol. According to common views, it is obvious, there is no point to discuss such a trifle, for buying a car or real estate is more important, so I want to argue here for the fact is the whole process of manufacturing might include the resources of several states to bring to the final client, which includes heavy transporting and local advertising. The micro devices are final and resulting ones for any area of science and technology.

The unit consisting of 2 parts one plugged into another is formatted up to 8 Gb memory capacity. The price was approximately 9$ for 8Gb unit, that is 1.13$ of 1Gb. It is cheap, and will be cheaper. The manufacturer is reportedly China, there are several plants in China or elsewhere. The choice was 8Gb for several reasons, first of all it can be easily stolen or lost. And finally according to the memory device usage and number of plug-ins, plug-outs. The best choice would be to have 2 units 2+32Gb, or 2+64Gb, in this case it will be optimal.

I bought the card 8Gb capacity. You see many of us have no relation to it. I will explore it later on corrupted areas and the file system. The USB is 2.0.
