Deskstar vs Ultrastar?

Recommended Posts

What's the difference?

Ultrastar carries a longer warranty but the comment "for lower duty cycle enterprise applications" has me worried. However, the 'self-protecting throttling of I/O" seems beneficial.

I'm going to migrate an existing 5 drive RAID to the 1TB drives and can't decide which one. Mostly a home theater server but I do some video editing. Speed isn't the primary concern. Mostly low heat and long life.

I don't suppose any other 1TB drives are available.

Ultrastar is HGST's enterprise (higher duty cycle) and nearline-storage (lower duty cycle/lower perofrmance) line, as compared to Deskstar, which is a consumer grade line with the lowest duty cycle and lowest performance of all three listed.

I would grab the Ultrastar A7K1000's (which are basically just 7K1000's with slightly different firmware, optimized for multi-drive RAID use) over the 7K1000's if you are concerned about it.

Seagate's 7200.11 1TB is sampling and supposedly has shipped in small volumes but I haven't seen any production lots yet. Samsung's F1 1TB appears to be vaporware.
