|komondor||there are very few enterprise class drives with the same specs as consumer drives there are some tween sata 7200 rpm drives that you can buy but they say they are not really made for heavy use.|

Bottled water costs 100x as much as tap, but real scientists in the bottled water industry claim it's better than tap.

Then again, I'm also referring to enterprise class drives that you can't buy off the shelf or at Newegg. They're designed specifically for a given set of storage systems, but are based on the standard Hitachi and WD enterprise class drives.

Interesting stuff... so it does seem like 'enterprise grade' drives are physically different, at least one should assume that they should be AT LEAST as reliable as 'consumer' drives.
I would be interested in getting more information about this 'power on/off' stuff. I keep most of my computers powered on all the time.
I like green drives, but reliability is very important.... if black drives are more reliable, then perhaps I should buy more of them, but would hate to 'waste' the power. I can't recall a 'black' drive failing, but I do know I've had at least 1 green drive go bad.
Hmmmmmmmmm... but still this seems to be mostly speculation. It would be great if someone could point to something written by an HD hardware designer who knows his stuff.

|slapshot136||well that intel write-up's MTBF should be a good indicator, 1.2 million hours at 45º C vs 700 thousand hours at 25º C|

|slapshot136||higher MTBF, higher warranty, designed for more demanding use - yes?|

I recently asked about enterprise vs. regular HDs in Usenet's comp.sys.ibm.pc.hardware.storage newsgroup and was told there are no hardware differences.

|komondor||I have enterprise drives at work they weigh more I can tell you that the 2 1/2" drive weigh a lot more than a standard laptop drive. For hard drives and power supplies I buy on weight|

I'm not convinced that the WD Black models have a lower failure rate than the Blue or Green series, but they do have a longer warranty.
Enterprise -> 5 years
Black -> 5 years
Red -> 3 years
Blue -> 2-3 years
Green -> 2-3 years
