As for 2.5 inches of attaching externally drive case "GH-HDCU325 series to be able to make a favorite drive into a external drive," there is GH-HDCU325B which adopted GH-HDCU325A and the resin case which adopted an aluminum case. I adopt USB3.1 Gen.2, and transfer utilized the rapidity of SATAIII is possible. It is most suitable for carrying around, and be accompanied, and it is gone for a drive by USB Bus power if I attach strong SSD to a shock by an AC adapter unnecessary. As it is attached, and the Type-A to Type-C conversion connector is attached more, even various can use USB Type-A to Type-C cable for USB3.1. The recommended of 2.5 inches of attaching externally drive cases! It supports USB3.1 Gen.2, and transfer utilized transfer speed 6.0Gbps (theoretical value) of SATAIII SSD/HDD can carry SSD to possibility up to 2TB, and AC adapter unnecessary UASP mode correspondence does not guarantee accessories USB3.1 correspondence USB Type-A to Type-C cable (40cm), Type-A to Type-C conversion connector, a prevention of vibration seal (in the case of a thin hard disk, I use it), the use by the drive of all the instruction manual warranty precautions with the USB Bus power with the simple assembling USB-TypeC conversion connector which there is no screw in to transparent skeleton specifications (GH-HDCU325B-BK resin case model) [GH-HDCU325A-BK/SV aluminum case model] standard USB3.1 Gen2 connector USB type-C interface Serial ATA Revision 3.2 that the product made in strong aluminum case (GH-HDCU325A-BK/SV aluminum case model) inside is seen, Serial ATA 6Gb/s(3Gb/s, 1.5Gb/s) correspondence drive size 2.5 inches correspondence drive thickness 7mm 9mm most macroscale 2TB for one year for chip set ASM235CM power supply voltage 5V (I feed it from the Universal Serial Bus port) transfer speed 6Gbps (theoretical value) operating temperature range 0 degrees Celsius - 60 degrees Celsius movement humidity range 0% - 95% (thing without the dew condensation) storage temperature range 5 degrees Celsius - 35 degrees Celsius storage humidity range 25% - 60% (thing without the dew condensation) external form dimensions W122 X D78 X H15(mm) about 84 g in weight RoHS2 correspondence material aluminum +ABS term of a guarantee. SSD/HDD is not attached. Please prepare separately. Also, by the difference in calculation method of the memory capacity, a part of the memory capacity cannot use all the memory capacity of mention to a product to be different from the memory capacity (I calculate 1KB as 1000byte) of mention in a product to capacity (I calculate 1KB as 1024byte) in the to be used as system area and a spare domain. The notation of the transfer speed is all the maximum at the time of the sequential access, and the speed varies according to use environment.
