Affordable External Storage - HP vs Buffalo 1TB slim drives

 I've recently found all my drives (and I have a lot of them) are showing red.  I need more disk space and while looking I found a couple of good affordable choices here.  These are slim design models that require no power.  They are USB Powered and both are quiet running solutions that provide 1 TB of storage.

  • Turbo PC increases file transfer rates by up to 2X over competing USB 2.0 portable hard drives

Now if you require the USB 3.0 compatibility just buy the 3.0 version to the right the USB 2.0 is to the left below here.  Same price.

These products are both slim drives that require no power(just usb power) and the have the same disk space. The option for USB 2.0/3.0 is available for both products(The HP one supports both, whereas you would have to choose one or the other with the Buffalo).

Of the two, many would say HP is a more reputable and solid product.  Not me.  I find you'll pay more for the same product quality or life expectancy in a lot of situations.  As a result I'm going with the cheaper buffalo drive for a small, convienient, attractive and cheap storage solution.
