How to Choose
Getting the best HDD deal is mostly about timing and knowing where to look. Here are the factors that matter most.
Price per TB
The single most important metric for value buyers. A lower total price does not mean a better deal if the drive is smaller — always compare on a per-TB basis.
New vs refurbished
New drives include a manufacturer warranty (typically 2–5 years). Refurbished datacenter pulls are often 40–60% cheaper but come with shorter seller warranties. Both are valid depending on your risk tolerance.
Capacity
Larger drives cost more in total but usually deliver a lower price per TB. If you have the budget, buying fewer large drives is more cost-efficient than many small ones.
Recording technology
CMR drives handle random writes and RAID rebuilds better than SMR. For single-drive use or sequential workloads, SMR is fine and often cheaper.
Frequently Asked Questions
What is a good price per TB for a hard drive in 2026?
For new drives, $12–15 per TB is a solid deal on capacities of 8 TB and above. Refurbished enterprise drives can drop below $10/TB. Prices shift daily, which is why HDDHunt tracks them hourly.
Are refurbished hard drives reliable?
Datacenter pulls — drives retired from server farms after 3–5 years — are generally reliable. They were built for 24/7 operation and often have plenty of life left. The trade-off is a shorter seller warranty (typically 1–2 years) instead of a manufacturer warranty.
Should I buy one large drive or several smaller ones?
Fewer large drives usually deliver a lower price per TB and use less power. However, multiple smaller drives allow for RAID redundancy. If you are building a NAS with parity, multiple drives make sense. For simple bulk storage or backup, one large drive is more cost-efficient.
What is the difference between CMR and SMR hard drives?
CMR (Conventional Magnetic Recording) writes tracks side by side and handles random writes well. SMR (Shingled Magnetic Recording) overlaps tracks for higher density but struggles with random writes and RAID rebuilds. For NAS or RAID use, stick with CMR. For sequential backup or cold storage, SMR is fine and often cheaper.
