THE WD40EFRX

Typically we received our sample inside a clear clamshell box (bulk).

Nothing new in terms of design since it’s almost identical to the 3TB model (WD30EFRX) which we reviewed 3 years ago.

Once again a large sticker at the top includes the product serial and part numbers, factory roll out date (roughly 1 year ago), cache size, capacity, electrical specifications, a 2d barcode and several certification logos.

At the other side of the drive we see the PCB without any components on the exterior (all are placed inside for optimal protection).

Moving at the rear of the drive we find the usual SATA power and data connectors along with 8 pins (probably used for firmware updates).
