The designer thought to travelers with this hard disk drive by putting different electrical plugs (europe, BG, USA). The disks are connected to the housing with 2 layers: 1 IDE, one for SATA. For even easier operation, it is possible to buy an additional adapter which then slips by the wayside above. To that used to use hard drives "raw" is very simple. For others, we may regret the lack of an underdeveloped manual. But I am not certain that neophytes are turning to this product (even if it is really easy to use).
4 star "only" because the assembly is a compact. If well thought out and finished product.
