In an effort to expand its product portfolio at no cost, Western Digital sold faster 7,200 rpm NAS hard drives under the guise of 5400 rpm NAS hard drives. This caused a misunderstanding on the part of users, who instead of quiet and cold drives received hot and noisy ones. Fortunately, customer pressure and common sense won out: WDC began reporting the real speed value.
Tom’s Hardware, citing German Heise.de, reported that Western Digital has changed the names of the 8, 10, 12 and 14 TB WD Red Plus series hard drives in order to align them with the new true specifications. The old names have been retained, since these models have been sold for a long time and come with a warranty. The specifications of the new models indicate the current spindle speed of 7200 rpm, while the specifications of the models with the old name will say “class 5400 PRM”. Below you can see the new model designations and their previous names:
- 8 TB: WD80EFBX (-68AZZN0) instead of WD80EFAX (-68KNBN0)
- 10 TB: WD101EFBX (-68B0AN0) instead of WD101EFAX (-68LDBN0)
- 12 TB: WD120EFBX (-68B0EN0) instead of WD120EFAX (-68UNTN0)
- 14 TB: WD140EFGX (-68B0GN0) instead of WD140EFFX (-68VBXN0)
In addition to model names, the value returned by the utilities for tracking SMART indicators has been changed. The SMART parameter now clearly indicates the rotation speed of 7200 rpm for such hard drives. Western Digital also began to edit the pages on their sites with related products. Somewhere changes have already been made, somewhere else not.
The scandal with the discrepancy between the parameters of the real and the declared rotation speeds of WDC NAS drives has long been discussed on specialized forums. One of the active users even measured the rotational speed of suspicious hard drives by recording drive noise. When the truth came out, the WDC preferred to silently write real rotational speeds into the specifications of hard drives, rather than “marketing” ones.
