Hi,

Looking to build 2.5" 1TB external HD with USB3.0 and 5400rpm.

Is there a difference for SATA6/3 if only used externally?

Does 7200rpm require more power? I read that it needs 2 USB connectors.

Any recommended enclosures or 2.5" models? I'm looking at WD 10 JPVX 1TB, 8MB 5400rpm, SATA 3Gb/s. 9.5 mm

True that! The WD Green would spin down thanks to the IntelliPower and it's a bit bigger in height. However, since you've already got the enclosure and the 1 TB capacity is enough, I guess it won't work for you.
As I already mentioned, the WD Blue is just as good a mobile storage solution. As for the power it would require, any mobile 2.5" HDD can be supplied with just enough through the USB hub without any additional AC adapters (in comparison to the 3.5" bigger bros - the desktop HDDs). So yes, a single USB 3.0 enclosure should be more than enough for the WD Blue 2.5" as well.

Good luck! Hope I was helpful! :)

Hey there, dfk!

+1 for @Ironsounds and his thorough response!

Thought the WD Blue WD10JPVX is definitely a good mobile storage solution, it's mostly used in laptops and notebooks for everyday purposes. However, its largest available capacity at the moment is 1 TB, which I personally don't think is enough for a backup external storage (but it does depend on the files you're planning to store there).

We have the WD Green 2.5" mobile HDD that is designed and recommended for use in custom-built enclosures and other applications that require cool and quiet operations (which is exactly what you are planning to do,right?). Its RPM is IntelliPower - which is a fine-tuned balance of spin speed, transfer rate and caching algorithms designed to deliver both significant power savings and solid performance. The available capacities for the 2.5" form factor WD Green are 1.5 TB and 2 TB. I'd recommend you to take a look at its features and more detailed specifications here: http://products.wdc.com/support/kb.ashx?id=VjR6PR

I hope it helps. Keep me posted if you have any questions about it! :)

Hi, and thanks for both of your replies. I didnt consider WD Green because its height is 15mm according to this site: http://www.wdc.com/en/products/internal/mobile/ and I wanted one to be compatible with most enclosures and possibly also my vostro 1400 caddy. 1TB is enough for me and I'm limited to USB3.0 for now. Also read some comparisons that WD Green might be slower compared to Blue because of spin up time when it's in low power mode though I may be wrong. Would a single USB3.0 be enough power for a WD Blue, if so I might just get it.
