Between 4K videos, raw photo files, game libraries, and endless work documents, running out of storage space feels like a monthly crisis. The Seagate expansion 20TB external hard drive solves this problem in one massive swoop, and right now, Amazon has slashed the price from $499 down to just $229 for both Prime and non-Prime members. This early Black Friday deal beats even Seagate’s own website pricing, and here’s the kicker: you’re paying the same price you’d normally fork over for a 10TB drive.

Massive Storage Meets Desktop Convenience
This is not a portable drive you will slip into your pocket: The Seagate 20TB device is a desktop unit that requires its own power supply which gives it the muscle to deliver consistent performance for your bulkiest files. Inside the black enclosure lives a 7200 RPM Seagate BarraCuda drive with a 512MB cache, pushing read speeds around 246-257 MB/s and write speeds of 239-256 MB/s according to real-world testing. These numbers mean you can transfer a 50GB game in about three to four minutes, or back up your entire photo library from the past decade without aging five years in the process.
The drive connects via USB 3.0 using a micro-USB port and it comes pre-formatted in exFAT so both Windows and Mac machines recognize it immediately. Just plug in the included 18-inch USB cable and 18W power adapter, and you’re ready to drag and drop files without installing a single piece of software. Mac users who want to use Time Machine will need to reformat the drive, but that’s a quick one-time setup.
It also includes Seagate’s Rescue Data Recovery Services which means if the worst happens, you’ll have access to pro data recovery. The service covers everything from accidental deletion to physical damage; you’d need to check the fine print for limitations. You also get international power adapter plugs, which are a nice touch if you travel or switch countries. There’s a one-year limited warranty on the hardware while most external drives tend to run hot during operation, this one reportedly stays at around 55°C, which is warm but not concerning.
The real story here is value: While the prices of external drives have dropped, this deal presses the cost per terabyte down into territory usually reserved for smaller capacity drives. It’s large-capacity drives make sense for media professionals, gamers with massive libraries, or anyone needing to archive years of files without having cloud subscription fees eat into their budget month after month
This drive won’t supplant a speedy NVMe SSD for active work, but for long-term storage, or consolidating scattered files across multiple older drives, it delivers exactly what most people need. You’re getting a 20TB drives in one unit for $229, which means you’re paying $0.01 per GB. And this is a record low.
