HGST Ultrastar 7K4000 Review (HUS724040ALE640) Discussion

4 posts in this topic

HGST's Ultrastar 7K4000 3.5" form factor enterprise-class HDD now ranges up to 4TB in capacity and spins at 7,200RPM while interfacing over SATA 6Gb/s. The drive offers the enterprise a 33% capacity leap over previous models, and it accomplishes that task of delivering robust capacity by utilizing five platters at 800GB each to attain the maximum 4TB capacity. This is a huge feature for enterprise customers who need to maintain the same footprint for their drives without increasing their costs. Another significant feature on the Ultrastar 7K4000 is that it is offered in Advanced Format which uses a 4096-byte sector size that is still backward-compatible with the 512-byte sector size. The HGST 7K4000 drive also features 64MB of drive cache.

Hmm. Doesn't look too bad, but doesn't look great either.

Is there a Seagate Constellation ES.3 4TB review anytime soon?

Next 4TB review will be the Toshiba SAS and SATA drives probably. Seagate CS mixed in between. We don't have an ES.3 in SATA yet, just the SAS that we reviewed previously.

The SAS ES.3 was quite strong, so I'd expect the SATA model to do as well.

Power consumption measurements would be nice to see if there's anything to HGSTs claims.
