6TB Drive Comparison & DIY Storage Pods

The Backblaze Pod updated w/ 6TB Drives

Here’s a recap of BackBlaze’s transition from 4TB to 6TB hard drives in their storage pods. Over 10,000 hard drives to be purchased.

6TB Faceoff

  1. Initial reliability (how many drives failed) – No failures.
  2. Running reliability (3 months) – No failures
  3. SMART Stats (3 months) – No error conditions recorded for the 5 stats that we utilize.
  4. Hard Drive Cost – about the same.
  5. Energy Use – The Seagate drives were 7200 rpm and used slightly more electricity than the Western Digital drives which were 5400 rpm. This small difference adds up when you place 45 drives in a Storage Pod and then stack 10 Storage Pods in a cabinet.
  6. Loading speed – Edge to Western Digital, by a little over 1 TB per day on average.
