Compare NAS HDDs and SSDs on the facts: CMR vs SMR, SSD endurance (TBW/DWPD), real Backblaze failure rates, and the live cheapest price/TB across 7 regions. Free, no login. Open CC BY 4.0 dataset + API.
CMR vs SMR
Judged per model; SMR flagged (can stall a RAID rebuild)
Real failure rates
Annualized failure rate computed from raw Backblaze Drive Stats
Live price-per-TB
Cheapest $/TB across 7 Amazon regions, refreshed daily + price history
SSD endurance
TBW/DWPD, NAND type, DRAM, power-loss protection; QLC flagged
Open dataset + API
Full specs + CMR/SMR data, free CC BY 4.0, CORS API
Price tools tell you the cheapest drive but not whether it's secretly SMR (which can stall a RAID rebuild) or how reliable it is. NASdisks adds CMR/SMR per model and real Backblaze-derived failure rates, so you buy on facts, not a vendor MTBF brochure. No login, nothing gated, and the data is open.
Home NAS and homelab builders, self-hosters, IT/sysadmins, and small businesses choosing drives for a NAS - anyone who wants to compare on reliability and price per TB, not just marketing specs.
It pins real failure rates - computed from Backblaze's raw Drive Stats - to specific currently-sold drives, alongside CMR vs SMR judged per model, SSD endurance, noise, and the live cheapest price-per-TB across 7 regions, all in one sortable table. Most tools show price only; NASdisks adds reliability and recording tech. The full dataset is open (CC BY 4.0).
I built it because every time I speced a NAS I hit the same wall: "NAS" on the box tells you nothing about whether a drive is SMR, and vendor MTBF numbers are marketing. I was tracking CMR/SMR, failure rates and prices in spreadsheets, so I turned it into a public tool.
Laravel (PHP), Tailwind CSS, and Vite, deployed behind Cloudflare. Reliability is computed from Backblaze's raw Drive Stats; prices refresh daily from Amazon.
