HDD Question

[cornemuse]

Just a question,

What is the difference between a desktop internal hdd and a 'network nas' internal hdd??

Frys has a WD 1T nas drive for 49 bucks, how would it work in a desktop?

As I understand things, there is some sort of compression involved with nas drives. Am I being lead??

NAS drives are rated for heavier duty usage, higher temperatures, and may have longer warranties.

As jagabo wrote + usually there is no mechanical difference - some differences can be introduced at HDD firmware level - for example different caching strategy, different error correction (matrix/RAID HDD's are usually provided with weaker ECC as error correction is achieved at matrix level) there can be different timeout strategies etc - usually there is no full, detailed list with deltas between HDD's families.

nas drives have different firmware to do things like reducing rpm or spinning them down when not being accessed to reduce heat and wear. not ideal for max performance in a desktop.

Got it! Thanks for replies.

Desktop drives are expected to be powered on/off daily (or whatever) when the PC is used. A NAS drive is expected to run 24/7.

I believe WD Red drives are not rated for 100 percent duty cycle like enterprise NAS drives are. They are specifically for SOHO situations with much lighter use. Unfortunately, details are nearly impossible to come by unless you are a volume customer. I suspect they are the same as desktop drives just with minor firmware tweaks and longer warranties.

I believe the "tweaks" are the spin down timers.
