WD Red Pro 8TB vs WD Gold 8TB

First, amazon.in has retarded pricing, i bought a red 2tb locally for about 1k less than the cloudtail price. Second, a friend just bought a 1tb red and it came in a plastic shell, but without the anti static bag that they're shipped in. Dunno if it's because of the plastic bag ban, but even the replacement he asked for came that way.

On to the topic at hand, a quick google suggests that gold seems to be better:

The differences for 10TB drives are (Red Pro specs, Gold specs):

  • Slight bump in performance. Gold can do 249MB/s, Red Pro can do 240MB/s.
  • Gold has an MTBF of 2.5 million hours, Red Pro only 1 million.
  • Gold has an annual failure rate spec, Red Pro does not.
  • Red Pro has a workload rate of 300TB/yr, Gold's specs are defined for a workload of 219TB/yr but the drives are designed for 550TB/yr.
  • Gold is more power hungry. 7.1/6.7W for sequential read/write vs. 5.7W on the Red Pro. 5W idle vs. 2.8W on the Red Pro.
  • Gold has a higher operating shock rating of 70G vs. 30G read write, 65G read only on the Red Pro.
  • Gold is slightly louder on seeks at 36dBA vs. 29dBA
  • Gold weighs 10g more than a Red Pro.
TL;DR: Gold is specced to be more reliable but consumes more power.

To my knowledge, the Golds are meant for data centres with high density with a mix of performance and storage. They will have longer life due to higher vibrational capabilities. The Reds are meant for storage only, with the Por between Gold and Red.

The Golds consume more power vs the Reds/Reds Pro.
