Delivery + finest AMAZON price. SD works perfectly USB3 and 3TO PC (WIN 7 64 bit) and even better on the Samsung TV UE65HU8200 UHD 3D CURVE. It is beautiful, quiet, and the transfers are fast. Only USB 3.0 / 2.0 (no e-SATA), but this is no longer necessary because the USB speed is comparable to 3 e-SATA plus a hot start (without reboot of PC) Note: I hesitated between this model and the Western Digital Elements Portable Drive (2TB USB and 3) and I do not regret my choice.
