How much extra heat does a 7200 rpm drive produce vs a 5400 rpm drive?
Basically what the deal is I got 2x 2TB hitachi drives for 218 dollars total, they were on sale for that incredible price 109 each. I can trade them for 2x 5400 RPM Western Digital AV-GP Green drives + 60 dollars to a classmate of mine that does video editing and wants to upgrade to 7200 RPM.
Am I better off with the 7200 RPM hitachi drives or should I go for the money savings and heat generation savings (is the heat difference even noticeable?) and go with the AV-GP WD green drives? I also think the AV-GP line of WD green drives are more reliable since they are meant for 24/7 operation in DVR's.
Basically it comes down to what will I benefit more from.
Pros 7.2k Hitachi Drives
-faster speeds
-drives are brand new unused
-full 2 year warranty
-SATA III interface
Cons 7.2k Hitachi Drive
-More Power
-More heat
-won't get extra 60 dollars
Pros 5.4k Western Digital Green AV-GP series
-lower power consumption
-lower heat output into my case
-Made for 24/7 Audio Video Storage and Retrieval
-probably more reliable
-60 dollars saved
Cons 5.4k Western Digital Green AV-GP series
-slower speed
-15 month old drives not new
-6 months less of active warranty
-SATA II interface
I'm assuming for audio and video mass storage the speed difference between the drives is a moot point. I don't know if the heat generated is really that much different either. What would you guys do, keep the brand new hitachi deskstar 2TB 7.2k drives or trade them for WD green AV-GP 24/7 A/V DVR 2TB HDD's and put an extra 60 in my pocket?
I'm leaning towards keeping the hitachi's unless the WD drives produce a measurable amount of less heat or these AV-GP drives really are built with a lot more quality and reliability since they are labeled as being specially made for 24/7 DVR environments
