I am looking for a back up hard drive and I'm not sure which one to purchase. I am looking at the Segate GO Portable or a Calvary Preformated External Hardrive. Help?
Answer
The difference between a portable and external hard drive is that a portable hard drive usually doesn't need a power cord for power and an external drive does. Portable drive also may run slower and will have smaller capacity. Depending on your use and if you plan on carrying your data around then you best bet is to go with an external hard drive. If you have an eSATA port on your computer try to find an external drive that supports that feature. This will give you better speed (USB 2.0 is 480Mbps while eSATA is 3 Gbps). If you are using a laptop only and want to back that up then go with a portable drive so you can plug and unplug it easily.

External Hard Drive: Portable vs Non Portable?

Hey everyone,
I am planning to buy a new external harddrive for everyday use like movies, music,pictures etc. I will be connecting it to my xbox mostly to watch movies. Now i had Western Digital Elements 1TB and it only lasted for a year. There are two types that am confused between the portable ones (which are smaller in size) and regular big ones. If you guys could tell me if there is any other difference than the obvious size difference? I know portable cost just a bit more. But is there any speed difference. Also does big ones last longer than portables? Also which one you guys recommend? I was looking to buy for under $150. Size 500 GB - 1 TB.
Thanks
@I M Here is what i mean by Portable: http://www.amazon.ca/Western-Digital-Passport-Essential-WDBACX0010BBK-NESN/dp/B0041OSQ9S/ref=sr_1_6?s=electronics&ie=UTF8&qid=1304901244&sr=1-6
Non Portable: http://www.amazon.ca/Western-Digital-Essential-External-WDBACW0010HBK-NESN/dp/B0041OSQB6/ref=sr_1_51?s=electronics&ie=UTF8&qid=1304903779&sr=1-51
See Portables are smallers and little pricey than NON portables
Answer
Non-portable is better.
The portables draw power via USB and can run into problems if too many devices are plugged in (unless you're using a USB hub with its own AC adapter). Portables are also physically smaller and slower spinning.
But personally I don't recommend external non-portables either. The BEST solution is to buy a regular internal hard drive and a USB housing.

The USB interface on external drives often fails long before the drive itself does. Sometimes it's due to drops or hard bumps- incidents which seem to increase in frequency as drives get smaller. The simple fact is that devices which fit easily into a backpack, shirt pocket or purse are tossed around more casually and suffer more bumps and bruises than devices which are less convenient.
Sometimes a fall simply dislodges a connector, other times the interface board gets broken by the impact or fails due to heat or power problems, but the end result is similar. You need to open the case in order to fix the problem.
But many external drives come in sealed casings, making it nearly impossible to remove the drive inside without destroying or damaging the housing. Some have proprietary formatting or aren't recognized when connected to a USB interface other than the original manufacturer's. And too many come pre-loaded with bloatware.
Worst of all, many external drives don't have any form of active cooling which makes them more prone to overheating and early failure when used for extended periods of time.
With a regular internal drive and fan-cooled generic case, you can quickly recover from a failure of either the enclosure/interface or the drive. Replacing either is easy.
