Only at Best BuyStore files securely on this 4TB Western Digital hard drive. It comes several pieces of utility software installed for ease of use, and it backs up files automatically so you don't have to. This Western Digital hard drive is USB 3.0 compatible for transfer rates up to three times faster than compatible drives.
These are Western Digital Reds with a normal SATA connector when taken apart. The USB "proprietary" connector the other reviewer is talking about is *NOT* this drive (he / she is referring to the 2.5 inch portable drive with the same name).
I bought a total of 5 (three from one store, and two from another - due to best buy's non-business purchase limitations) and they all turned out to be Western Digital Reds. The bare drive does show it has a 2 year warranty, but it's description is "WD easystore Desktop" with a model number of "WDBCKA0040HBK" when you do a warranty check on the WD website.
All of mine are model: WD40EFRX & have NASware 3.0, with a mfg. date of March 2nd, 2017.
