Best 6TB Hard Drives by Price per TB
As an Amazon Associate we earn from qualifying purchases.
For a NAS or RAID, buy a 6TB drive from a line that is CMR at this size, because several 6TB desktop drives and plain WD Red are SMR; for a single backup or PC drive, either works, so compare price per TB below.
A 6TB hard drive suits a second drive in a desktop PC, a first NAS, a home backup, or extra storage for a PS5 or Xbox. It holds a large media library in one drive. The list below ranks today's Amazon offers for exactly 6TB — internal and external, new, renewed, and used — by price per TB, and re-ranks itself every time our price snapshot refreshes.
6TB is the largest size where SMR is still common. Seagate's and Toshiba's desktop drives are SMR here, plain WD Red tops out at 6TB and is SMR, and Seagate's SkyHawk comes in both a CMR and an SMR version at this size. The NAS-class lines are CMR, so the recording method decides whether a cheap 6TB drive belongs in a NAS.

What to look for
Check the recording method before the price. At 6TB, Seagate's BarraCuda desktop line, Toshiba's P300, and plain WD Red are SMR, and one of Seagate's two SkyHawk 6TB versions is too, so read the maker's spec sheet for the exact model. Seagate IronWolf and IronWolf Pro, WD Red Plus and Red Pro, and Toshiba N300 and X300 are CMR. SMR is fine for a single backup drive; in a RAID array, a rebuild's sustained random writes can slow it sharply.
Match the warranty to how hard the drive will work. Desktop-class 6TB drives carry a 2-year warranty, with Seagate's desktop line rated for 55 TB per year. NAS-class drives get 3 years and a 180 TB-per-year rating, and pro NAS lines get 5 years with higher ratings. For a drive that runs around the clock in a NAS, the longer warranty and higher rating are what you are paying for.
Read the condition on every row. Amazon's Renewed Guarantee allows a return within 90 days, and Renewed Premium extends that to a year. Seagate sells recertified drives directly with a 6-month warranty and WD with a 1-year warranty, while other renewed listings carry only the seller's warranty. A 6TB drive also fits a PS5: Sony supports USB extended storage from 250GB to 8TB.
FAQ
Is 6TB a lot of storage?
For most home users, yes. 6TB holds about 1,200 movies at 5 GB each in 1080p, or about 120 at 50 GB each as 4K disc rips. Windows shows it as about 5.46 TB because it counts in binary units; nothing is missing.
Is a 6TB hard drive good for a NAS?
Yes, if it is CMR. At 6TB, Seagate's and Toshiba's desktop drives, plain WD Red, and one SkyHawk version are SMR, and SMR can slow sharply during a RAID rebuild. NAS-class lines such as IronWolf, WD Red Plus, and Toshiba N300 are CMR at this size.
Can I use a 6TB hard drive with a PS5?
Yes. Sony supports USB extended storage from 250GB to 8TB over USB 3.0 or faster, so a 6TB drive fits. PS5 games stored on it must be moved to internal storage before you play them; PS4 games play directly from the external drive.
What is the cheapest 6TB hard drive?
It changes daily, so this page ranks today's Amazon offers live by price per TB. Before buying the top row, check whether it is SMR, which is common at 6TB, and whether it is renewed with a shorter seller warranty.
