External Drive

The first and last one appear to be powered by the USB which sometimes cause problems. Also, they seem to be 2 1/2 inch notebook drives which are typically 5400 RPM which are slow than the 7200 desktop drives used for the others. The others appear to require use of a wall power supply..

If any of the drives tell you to install backup software or other software I would very likely not install it.

I would go for 2, 3 or 4.

I have so many external drives I might have inadvertently become an 'expert. On my iMac I use OWC & Iomega. On MBP I have LaCie with Western Digital MyBooks on both just for backups.

I recently bought a WD MyPassport Pro with in built Thunderbolt cable - what a revelation! I bought it from Costco & decided on the big 4TB version. Its the fastest drive I have ever had! I don't have the 2TB(The 4 is just 2x2TB in RAID) but a friend has & he says the same. BTW we had no idea they were fast - I bought mine for mass storage of video & photo's. It heavy but for what it does its worth the trade off.

Check out those WD My Book drives, the Mac ones not the 'vanilla' versions

I have had no problem with a Toshiba extern drives that I have purchased.

For reliability I prefer ones that require their own power supply.

The one you linked to is fine but slow because of the 540o RPM.

I do not know of any. Manufacturer's stopped making 7200 RPM 2 1/2 inch drives and 3 1/2 inch drives require too much power for USB powered drives.

Correct. You can't get a 5 TB 2 1/2 inch drive.

I have no objection to that one if y want a USB bus powered drive.
