TOSHIBA HDWR440
From Computing Classics Wiki
TOSHIBA HDWR440 is a hard drive model created by Toshiba. Part of the Toshiba X300 family, it is a 4 TB 3.5" 7,200 RPM CMR hard drive model. It succeeds the previous generation HDWE140, reducing the platter count to three while increasing the density from 1 to 1.6 TB per platter, and is a binned relabel of the TOSHIBA MD08ADA400E. The HDWR440 is Advanced Format and based on 1.6 TB platters; this is in contrast to its sister N300 model TOSHIBA HDWG440, which is based on 512-native platters with a reduced 1.33 TB density.

Trivia[edit | edit source]
- The HDWR440 has the least amount of platters of any model in the X300 family, at three. The previous 4 TB model, HDWE140, previously took that spot, at four, which the HDWR440's sister model HDWR460 ties for as well.
