An 8TB hard drive suits a small NAS, bulk storage in a desktop PC, a backup drive, or a game console's external storage. The list above ranks today's Amazon offers for exactly 8TB — internal and external, new, renewed, and used — by price per TB, and re-ranks itself every time our price snapshot refreshes. Expect Windows to show about 7.28 TB; drive makers count in decimal terabytes, so nothing is missing.
At 8TB, the drive class decides the recording method. Seagate's BarraCuda desktop line is SMR at this size, while the NAS-class lines from Seagate, WD, and Toshiba are CMR, which matters when a RAID array rebuilds. 8TB is also the largest USB drive a PS5 accepts. Decide what the drive is for before chasing the lowest price per TB.
What to look for
Check the recording method before the price. At 8TB, Seagate's BarraCuda desktop drive is SMR, while its IronWolf, IronWolf Pro, SkyHawk, and Exos lines are CMR. WD Blue is CMR at this size, WD Red Plus and Red Pro are CMR at every size, and plain WD Red isn't sold at 8TB. Toshiba's N300 and X300 are CMR. SMR writes large files fine in a single PC or backup drive; in a RAID array, a rebuild's sustained random writes can slow it sharply.
Don't pay extra for 7200 RPM by reflex. At 8TB, datasheet sustained speeds overlap at about 190 to 215 MB/s across 5400-class and 7200 RPM drives, and a 5400-class NAS drive can post a higher figure than a 7200 RPM one. A 5400-class drive usually runs quieter and cooler. Writing the whole drive at about 200 MB/s takes roughly 11 hours, which is the floor for a RAID rebuild at this size.
Match the warranty to how hard the drive will work. Desktop-class 8TB drives carry a 2-year warranty, NAS-class drives 3 years with a 180 TB-per-year workload rating, and pro NAS and enterprise drives 5 years. Renewed offers are often ex-data-center enterprise drives, but their warranty comes from the seller and is usually shorter. Age matters too: in Backblaze's fleet data, one 8TB model went a full year without a failure, while an older 8TB model, about seven and a half years in service, failed at an annualized rate above 10%.

FAQ
Which 8TB hard drive is the most reliable?
No single model wins; reliability varies more by model and age than by brand. In Backblaze's fleet data, 8TB models ranged from zero failures in a year to an annualized rate above 10% for an older model. For always-on use, pick a CMR NAS-class drive and favor a longer maker warranty.
Is an 8TB hard drive better than an SSD?
For bulk storage, yes: a hard drive wins on cost per terabyte. An SSD is the better pick when speed matters more than space, such as for an operating system or games. Compare this page with the SSD guides to see today's gap in price per TB.
Can I use an 8TB hard drive with a PS5?
Yes. Sony supports USB extended storage from 250GB to 8TB over USB 3.0 or faster, so 8TB is the PS5's maximum. You can store PS5 games on it but must move them to internal storage to play them; PS4 games play directly from the drive.
Should I get a 5400 or 7200 RPM 8TB drive?
At 8TB it matters less than you'd expect: datasheet sustained speeds overlap at about 190 to 215 MB/s, so 7200 RPM isn't automatically faster. A 5400-class drive usually runs quieter and cooler. For a NAS, pick a CMR drive first and choose RPM second.
