what is the power consumption of the drive?

I don't assume it would be any different from any other drives. Consumption for a SATA 7200 shouldn't ever exceed 20 Watts. It's usually in the range of 6-8 idle and 8-10 in read/write mode. If you are making the calculation for a power supply unit just account for it as a 20W to be safe and your calculation should be adequate.

Yes green drives are only 5200 RPM much slower than 7200 just to save 10 watts of power. The WD black drive is the highest performing mechanical drive there is.

Ron....no, the hard drive is a plug-n-play, no external power source needed.

Like most hard disks these days, the disk in this device enters sleep mode after a few minutes. This causes a slight delay when accessing it after the timeout. The power consumption is interesting - I received one with a 2 amp 12VDC power supply, and the device wouldn't start up. Once I replaced that with a 4 amp power supply, the hard disk spun up and the device started. Even 4 amp at 12VDC is negligible in terms of a home's power consumption, though, and as the disk spins down I should think the average power drain is minute.

depends on other hardware, graphics card, number of harddrives etc. google "psu calculator" and compute your power needs

I'm sorry I do not know, nor can I find any reference to its speed. I use thunderbolt to run my drive and it sizzles.

If the drive is a 5400 rpm or solid state then no power adapter required. If its a 7200 rpm or faster, power adapter is required.

I put 5 Seagate harddrives, powered up the enclosure and the Cyperpower UPS showed 36 Watt. The harddrives were idle (but rotating).

Identical devices should give the same performance whether they are USB powered or AC adapter powered. I think that if you have multiple storage devices attached to the PC and the performance seems slow, it would have to do with your mobo and not because of the USB attached storage device. This drive does not have an option for AC adapter power. USB is the only way to go.

My owners manual states that the power consumption is 35 to 80 watts depending on which fan setting is used.

Not exactly sure about your question. EVERY drive will need both a power cable and a data cable.

This particular drive is USB2. You'll get about 16 megabytes per second write, 20 to 30 read, depending on file size, fragmentation, etc.

Is the power adapter necessary for this drive or will it run off he computer battery if needed?

Your hard drive probably needs more power (current) than a single USB port can supply which is 5v @ 2A max

It's 5400RPM, so access times are "slower" than a 7200RPM drive. It has an 8meg cache vs. a 16m cache. I'd venture to say that neither of these are noticeable to the typical user. It's hot-pluggable SATA II, which are current capabilities. The 7200RPM/16m version is only about $5 more.
