WD My Passport Ultra 2TB vs Seagate backup Plus Slim 2TB ?


Oct 24, 2015

I want to purchase a USB 3.0 portable hard disk with support for USB2.0 as well and have narrowed my choice down to two:

1) WD My Passport Ultra 2TB (ver.2 - Apr 2015+)
2) Seagate Backup Plus Slim 2TB

Price is nearly similar for both.
I had earlier thought of buying the WD disk, owing to its size and since the OEM product page states compatibility with Win10 (my current OS).

I already own 2 portable hard disks -
1) Seagate FreeAgent Go 320 GB USB 2.0 (running fine since 2008)
2) Seagate Backup Plus Portable 1TB USB 3.0 (since 2013)

WD provides a better USB 3.0 cable, because I purchased a myPassport (v.1) for my father and it is more flexible than my Seagate Backup Plus cable, which I had to buy 3rd-party replacement cables for since the time I purchased it. My apprehension arose since I read somewhere that WD does not last long and will be more prone to disk failure/disconnection when writing data.

Though both disks provide a backup application, my existing Seagate BP-Portable came with a "lite" version and expected me to make do with it as the "Premium" application was available only in higher priced disks. The WD v.1 which I had got seemed to had all required features built-in and also had the ability to encrypt the drive and for locking it unless it was used on an "authorised" PC.

I do not wish to buy the WD My Passport v.1 because it will lead to confusion owing to 2 similar looking disks in the household. Also, my laptop has USB2.0 and USB3.0 but desktop does not have a USB-3.0 port and I run a USB hub from a USB2 port on the desktop, so will such hard disks work properly with it?

Advice on power requirement (only-on-USB/plugged-in etc with no external power source), data transfer speed and device durability will also be helpful, since I am unaware of these on the concerned devices. Kindly help as I am running out of space and need to purchase a hard disk ASAP.

Thanks in advance,
Both disks are Windows 10 compatible and will work on USB 2.0 or 3.0 without issues. Neither requires external power sources, but your USB hub might need to be powered if you have any other high-draw devices (like another disk).

WD actually has better reliability in some tests than seagate, though experience will vary by specific models and lot.

I personally would go with the WD. If you have an issue with disks looking the same, just get some paint or stickers and you're good to go.

I have poor experience with WD, hence my answer is based on my personal opinion. I would go with with Seagate due to my experience with its greater reliability.
