Akash jain Estimated Read Time: 1 Minutes
TL; DR: ST4000VN006 is the newer model with higher cache, higher transfer rate and lower RPM. Both the drives are CMR.

Seagate has introduced the new model of the 4TB Ironwolf - ST4000VN006. The old model ST4000VN008 is slowly being phased out. It may take another 3-4 months before the new model appears in the compatibility list of all NAS vendors.

What has changed under the hood

For one, the number of platters. The new drive is lighter and thinner, which means it has a smaller number of platters.

What has changed in the specifications

  • With a maximum transfer rate of 202 MB/s, the ST4000VN006 is faster than the 180 MB/s of the ST4000VN008.
  • A larger cache of 256MB in the ST4000VN006 , compared to 64MB of the ST4000VN008
  • A lower spindle speed of 5400RPM in the ST4000VN006 , compared to 5900 RPM of the ST4000VN008
Despite the lower spindle speed, the power consumption has not changed and the transfer rate has gone up, probably due to a higher cache and data density.

What has remained the same

Everything else has remained the same. These are the same air-filled CMR drives with a 3-year limited warranty and 3-year Data Rescue.
