Usually either Green or Blue.
Reds are mostly used for a Network Accessed Storage (NAS) eg. My Clouds
Major Difference between My Books and WD Elements is …
My Books have Password Protection and Hardware Encryption and Software.
WD Elements don’t. (Which is why they are usually cheaper. … they are basic no frills storage.)
Something to consider before purchase: if a My Book enclosure fails you can’t remove the hard drive and place it in a different enclosure to access your data … as it’s Hardware Encrypted.
if a WD Elements enclosure fails … you can remove the hard drive and place it in a different enclosure to access your data.
