Looking for lowest power consumption 2.5 hdd (no ssd)

Hi,

Im looking for 2.5 mechanical hdd that has the least electrical consumption, size dont matter (well at least 100GB), cant be ssd as its going the get heavy writes cycles, im assuming a single platter 5400rpm would be the best, but i have little experience in which laptop drive would be better.

Thanks for any suggestion,

 

You probably want to look at the Scorpio Blue 160GB (WD1600BEVT)

 

With 'heavy write cycles' I would not be looking for a 2/3 yr old (tech time) based drive. I have no doubt that the energy needed will be excessive compared to modern (current) models.

I would be looking at a WD Scorpio Black 750GB HDD partitioned/short-stroked to ~100GB (or as small as a capacity you can use).

This will be the most efficient drive with constant writing/reading to it (it will finish each request faster - allowing the drive to be in idle for longer periods than the slow Scorpio Blue drive would be).

Good luck.

 

Charts, benchmarks 2009 2.5? Mobile Hard Drive Charts, Power Requirement Idle

 

Thanks ill look into it.

Thank for the suggestion, but I made the mistake of not explaning it correctly, im not chosing an ssd out of writing too much probaly 100 gb a week, but its not intesive tasks, its more like downloads, so a fast or slow drive wont make a difference, although after ill transfer it to a server where it might affect the transfer speeds in gigabit lan, but this is not so important, woudl prefer to save $$$ on lower consumption drive. But i do understand what you said and makes sense, just not fully applies here.

Thanks for the chart, weird says 2009 but has the 7k750, maybe gets updated post 2009. Interesting those toshibas, not sure i could moun 1.8 drives though, but on the other hand it matches the blue suggestion above, so might do some serious search on that drive. For some reason i always though the 5k500B was one of the best but comes as mid table drive, in term of consumption.

 

100GB/week will not be an issue for an SSD. Intel estimates a five year lifespan with 20GB/day written (at least based on their warranty), and many believe 100GB/day is realistic. So you'd be safe to bet that 100GB/week is definitely safe. And you would probably get the best power consumption from an SSD, either OCZ (Sandforce), Samsung, or Intel.
