NOTE ON DRIVE AGE: These drives have a significant amount of runtime, roughly 3.8 to 3.9 years of power-on time each (33,361 to 34,536 hours). They test healthy today with clean SMART results, but they are used drives and no guarantee is made about remaining lifespan. Please factor this into your purchase and keep backups of any important data.
SETUPMy Cloud OS installs to the hard drives, so setup is done under your own Western Digital account. Nothing from the previous owner carries over.
Double-boxed, with the chassis secured. Drives and power adapter packed separately.
