FWIW Every brand will have some failures. For the price difference Why not think about a 2Tb External?
I use Seagate, Western Digital, Hitachi, And Toshiba
I am slowly switching over to Portable External drives. They only need the cable to USB port for data and power. That equals less clutter.
When buying a External drive, see if the colors are all priced the same. Some I bought the red version was $20 cheaper than the most expensive color. Not sure Why. Especially since the color is the difference.
Buy A USB3 drive, Even if You do not have USB3 now, sooner or later You will.
Remove the power from the drive when not using it. This will help with the drive life.
Always stop the drive using the "safely remove hardware and eject media" before disconnecting it.
Think about a NAS with Dual drives where the second drive is a exact image of the first drive. Mirrored drives.
For example I am using these for data backup where I would hate to lose the contents. Not to mention that I can access them over the network from any computer in the house.
QNAP TS-220 Diskless System Network Storage
Using these drives.
Western Digital Red NAS Hard Drive WD20EFRX 2TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive
Those drives are NAS drives.
I run one NAS 24 hours a day with no problems except It could use more space.
Remember that no Eternal drive likes any impacts and they like being dropped even less. So be careful.
