Recommend me a low power consumption 2.5 hdd

Im looking for the lowest power consumption mechanical drive on the market, minimum storage size 1tb , but eyeballing the new hitachi 5k1500 (not sure if it would consume more out of having more heads). I don't care about the speed, just that it consumes the least amount of power and that is 1tb or more, it has to be 2.5 hdd, but no limitation on width (in case those WD 2tb are efficient, ill go that route), also preferred if its quiet, main reason im looking into 5400rpms drives. I have good luck with Hitachi on the past, and probably that will be my route, but im open to other brands as long as fits better what i posted above.

Thanks for any suggestion,

 

I would not consider any other HDD at this point in time: Hitachi has always made the most balanced drives with regards to efficiency, quiet operation and highest performance. Not to mention the longest lasting and most durable, ime.

Go with the Hitachi; you won't go wrong.

 

Thanks tiller for your input, i have access to 3 hitachis 5400rpm 1tb or plus

HGST Travelstar 5K1500 2.5-Inch Mobile 5400 RPM 9.5mm Internal Bare Hard Disk Drives 0J28001
HGST Travelstar 2.5-Inch 1TB 5400RPM SATA 6Gbps 8MB Cache Internal Hard Drive (0J22413) (HTS541010A9E680)
HGST Travelstar 2.5-Inch 1 TB 5400RPM SATA 6Gb/s 8MB Cache Internal Hard Drive Kit 0S03508

I really would like to go with 1.5tb, but its triple platter, so im not sure if it be as quiet as the 1tb or consume the same power?

 

Yes, the 1.5TB drive will require more power to spin up (5W vs. 4.5W) and it will be slightly louder (2.5/2.7 Bels vs. 2.4/2.7 Bels), but considering that you have 50% more capacity than the 1TB drive, I think this tradeoff is more than acceptable. Especially when almost every other important spec is essentially identical.

That third link is for an external HDD kit... (it won't work inside your notebook, right...).


Good luck.

 

Well im probably going to go with 1.5tb, i do like the extra space. Thanks for the info on the spin up voltage, this is not an issue for me, but interesting none the less. What its important to me is the normal operation (not spun down) like im trying to have the lowest consumption that i can on this setup. Do you think the difference (0.5W) will also be like that on all day operation? not being fully stressed (like a benchmark), but like downloading a torrent file, atm im idling at 13W, and downloading at 16W, on Hitachi 5k500b (2x platter 250gb each), but 500gb is not enough, what i want to increase my storage but maintain the same idle or if i can lower it (i doubt i can), but overall i dont want to increase it.

Not sure what is kit though, checking the Hitachi website for that specific drive is displays 5 drives, like the new line with 500gb platters, to what i understand this is the only 1tb of 5400rpm of that line (there is another but its 7200rpm). I dont see any other drives that could be the retail boxed version, but not sure what is the kit or what would it affect it.

Thanks again tiller for your links and info, really been helpful,

 

No, the spin up wattage (power used) is only important if you cold boot the system many, many times a day.

In the other aspects (see the power section in the links provided), the power consumed is the same between the 1TB and 1.5TB models.

The difference is simply spinning the platters up to speed (but once that is done, it takes the same amount of power to keep them spinning).


Glad to have helped.

Take care.
