If you're shopping for a huge amount of local storage, here's a deal that beats pretty much anything I saw during Black Friday. For a limited time, Best Buy is offering this massive Seagate Expansion 20TB USB 3.0 Desktop Hard Drive for only $229.99 shipped. That averages out to a mere $11.50 per TB of storage.Seagate Expansion 20TB Desktop Hard DriveSeagate Expansion 20TB USB 3.0 Desktop Hard DriveThe Seagate Expansion boasts a single 20TB disk drive so it's no bigger than any other desktop hard drive. It features a USB 3.0 interface with roughly up to 100MB/s transfer speed, which is in line with what you'd expect from a traditional hard drive. It also includes recovery software and automatic recognition of both Windows and Mac computers.Although SSDs are all the rage these days, traditional hard drives are still the superior choice for long term storage. For one, hard drives are significantly less expensive. Compared to this hard drive's $11.50/TB cost, a solid state drive would run you at least $50/TB. Hard drives also have a much higher maximum capacity. Consumer SSDs generally cap out at 8TB, which pales in comparison to the 20TB capacity of this drive. Perhaps most importantly, although SSDs can equal HDDs in terms of lifespan, it's much easier to recover data from a HDD than SSD if either one fails.Looking for more alternatives?
