If you need a lot of storage without spending a fortune per terabyte, I've spotted a solid option to have on your radar.
Right now, the UnionSine 16TB desktop hard drive is now $423 (was $470) at Amazon. It's not the biggest discount in the world, but at this price, it works out to roughly $26 per terabyte, which is competitive for desktop-class HDD storage.
The drive uses a USB 3.0 MicroB connection rated for theoretical read/write speeds of 130-270MB/s, with UnionSine using an ASM chip solution aimed at broader compatibility across Windows, Mac, Linux, Android, and TV/DVD/Xbox devices.
Today's top desktop HDD deal
Save $47UnionSine UnionSine Desktop External Hard Drive 16TB: was $469.99 now $422.99 at Amazon
16TB capacity (approx. 14.5TB usable), 3.5" USB 3.0 desktop drive, up to 270MB/s theoretical transfer speeds, compatible with Windows, Mac, Linux, and more.
It's built around a 12V/3A external power supply, which is standard for desktop drives this size, and includes anti-vibration silicone internally to help keep noise down during extended use.
One important caveat: UnionSine isn't an established name in the storage space the way Seagate or WD are. If brand reputation and multi-year warranty support matter more to you than price per terabyte, it's worth weighing that against more established alternatives.
For anyone prioritizing raw capacity per dollar over brand pedigree, the UnionSine 16TB at $422.99 is a reasonable buy, though the discount itself is modest.
