description Seagate Barracuda 8TB Overview
Seagate Barracuda 8TB is an 8-terabyte 3.5-inch internal hard disk drive in Seagate's BarraCuda family, intended for desktop computers and other systems that accept a standard SATA drive. It stores data on rotating magnetic platters rather than flash memory, making it suitable for large collections of media, documents, backups, and other files where capacity matters more than solid-state access latency.
help Seagate Barracuda 8TB FAQ
Is the Seagate BarraCuda 8TB an internal or external drive?
It is a 3.5-inch internal SATA hard drive, not a ready-to-use USB external drive. Seagate lists the 8TB version as model ST8000DM004 in its BarraCuda datasheet. [Seagate datasheet](https://www.seagate.com/content/dam/seagate/en/content-fragments/products/datasheets/barracuda-3-5/3-5-barracudaDS2131-3-US2501-en_US.pdf)
Is the Seagate BarraCuda 8TB an SSD?
No. It stores data on rotating magnetic platters, and the listed 8TB model runs at 5400 RPM using SMR recording. [Seagate datasheet](https://www.seagate.com/content/dam/seagate/en/content-fragments/products/datasheets/barracuda-3-5/3-5-barracudaDS2131-3-US2501-en_US.pdf)
Will the BarraCuda 8TB work in a desktop computer?
It is intended for desktop systems that have a 3.5-inch bay and standard SATA data and power connections. Seagate also lists desktop PCs, all-in-one computers, and home servers as suitable application areas.
Can I turn the BarraCuda 8TB into a portable external drive?
Yes, but you need a compatible powered 3.5-inch SATA-to-USB enclosure or dock. The bare drive has no USB port, and a 3.5-inch HDD normally needs separate power.
