Still not sure which drive to buy for your NAS? This drive comparison list grew a lot: SSDs, price history, and more...
A month ago I shared a little NAS drive comparison I had built for myself, and the feedback here sent me straight back to work. It's a good bit bigger now. Here's what's new based on your suggestions:
- SSDs added - now not just HDDs. NAS and enterprise SSDs are in, with the specs that actually decide whether one survives as a cache or boot disk: endurance (TBW/DWPD), DRAM cache, power-loss protection, NAND type. No more guessing whether that cheap SSD wears out in a year.
- Price history per drive, from today back to around mid-2024. The one I use most: you can see whether today's price is a real low or just back to its normal spot, instead of trusting a "sale" tag. Handy for timing a buy while drive prices are this insane.
- Drive noise (idle and seek, in dB) and helium fill, both sortable - straight from requests in the last thread.
The original stuff is all still there and sharper: CMR vs SMR verified per model (SMR still sneaks into NAS lines), real Backblaze failure rates now refreshed with the Q1 2026 Drive Stats (so more models have real numbers), live price per TB across 7 regions, plus tools for RAID usable-capacity, array failure-risk, storage planning, and power cost. It's up to 208 drives now (all current drives that you can buy), and the whole dataset is open (CC BY) with a public API if you want to build on it.
One honest thing the data keeps showing: once you put error bars on the Backblaze numbers, most drives fail at about the same rate. So buy on price, CMR/SMR, and endurance - not on "most reliable drive" lists.
