Why WorthaByte is different
Full methodology →Price history, not hype
Our DealScore weighs each listing against its own price history and the wider market, so a fake “sale” gets caught instead of celebrated.
Compatibility before price
Recording type and interface come first. Host-managed SMR and other unsuitable drives are flagged or excluded — never buried in the results.
Real cost per usable TB
Compare total price, price per TB, and RAID-adjusted usable capacity with our calculators before you buy — not just the sticker price.

Buying guides
All guides →- CMR vs SMR hard drives: which is safe for a NAS?
The single most important spec for any RAID array — why SMR can stall a rebuild, and how to tell which one you're buying.
- Are recertified and refurbished hard drives safe to buy?
What “recertified,” “renewed,” and “refurbished” actually mean, when the savings are worth it, and how to lower the risk.
- What's a good price per TB for a hard drive?
Why price-per-terabyte is the only fair way to compare drives, and how to tell a real deal from a fake sale.
- RAID levels explained: 0, 1, 5, 6, and 10
What each RAID level costs you in capacity, how many drives can fail, and which one fits a home NAS — with a calculator to size your array.
- The 3-2-1 backup rule (and why RAID isn't a backup)
Three copies, two media, one off-site — what the rule means, why a RAID array doesn't count as a backup, and how to size the drives.
- Helium vs air-filled hard drives: does it matter?
Why high-capacity drives are sealed with helium, what it changes for heat, power, and reliability, and whether it should affect your buying decision.
