Backup drive: portable vs desktop

Desktop drives are often faster (RPM) than portable drives, but if that's not the case here, then why bother?

 

I have a Seagate Backup Plus Fast Portable drive and it's a really good bit of kit. Note the 'Fast' designation, it's two striped 2TB disks. Small size, no power adaptor required, decent capacity, speedy and a lot cheaper than SSDs. Best of all worlds if you ask me. I use it on my Xbox One and it's great for that (a disk failure is not that critical and it speeds up all load times).

 

The problem with Seagate and WD external drives is that they are all connected via a USB3 mini connector, which is prone to failure.

Even though it's more expensive, you're much better off with one of these:

1) It comes with a robust USB3-b connector
2) It has a 2nd USB3-A connector to daisy chain to another USB3 device
3) OWC uses Toshiba hard drives, which are more reliable than Seagate and WD desktop-class drives

 

That's unusual. I have 10 different kinds of OWC enclosures and all work brilliantly...

 

OWC's newer technology stuff is hit or miss. I went with a few USB powered 2TB drives as my archive and back-up drives. no need to dig out power supplies, etc just plug and back up. I even have USB powered drive on my time capsule...so far so good.
Toshiba drives are essentially Hitachi/WD as they were rebranded/bought out i believe.
Drive speed doesn't matter with USB, no mechanical drive can reach USB3 speeds currently.
The drive I recommend is the G-Technology 2TB Mobile Portable USB drive. about $99 or $179 for 3TB. this one is an actual drive connected to a sata board, not like the WD Passports where they are manufactured with the USB port on the disk itself. otherwise that seagate should do you fine.
