The Seagate Expansion model features a single 20TB disk drive, so its physical size is no larger than a typical desktop hard drive. It utilizes a USB 3.0 interface that provides transfer speeds of roughly 100MB/s, which is standard for traditional hard drives. The drive also comes with data recovery software and is automatically recognized by both Windows and Mac computers.

While SSDs are incredibly popular today, traditional hard drives remain the better option for long-term data storage. For starters, they are substantially cheaper. Compared to this drive's price of $11.50 per TB, an equivalent solid-state drive would cost at least $50 per TB. Hard drives also offer significantly higher maximum capacities. Consumer SSDs are generally limited to 8TB, far less than the 20TB available here. Moreover, while SSD and HDD lifespans can be comparable, recovering data from a failed hard drive is typically much easier than from a failed SSD.
