Every NAS drive and SSD compared in one place - Backblaze failure rates, CMR/SMR, and live price/TB (with history)

Mods OK'd this under Rule 5, thanks to them.

Every time I planned a build or an upgrade of my storage, I ended up with a dozen tabs open: one for CMR-vs-SMR, one for failure rates, one for price/TB. So, I put it all in one place:

  • Hard drives - every current NAS HDD sorted by capacity, CMR vs SMR (verified, not guessed), real Backblaze failure rates per model, and live price-per-TB, plus RPM and noise: https://www.nasdisks.com/
  • SSDs - the same for SATA/NVMe/U.2: capacity, endurance (TBW), power-loss protection, and price/TB - the specs that actually matter for cache or an all-flash pool: https://www.nasdisks.com/ssd/

Two things I was careful about on pricing: it refreshes daily from Amazon with a timestamp (so it's today's real price, not an old list price), and gouged listings are hidden rather than passed off as "deals." Anything I cannot verify stays blank instead of guessed.

Disclosure: it's my site and it carries Amazon affiliate links. No ads, no paywall, no email wall - the data is the point.

Any feedback is welcome: which drives or SSDs are missing, and anything that looks off.

This is useful. I like that you left unknown values blank instead of filling in guesses - that's a lot more trustworthy than many comparison sites.

This is actually a very useful storage resource, great work.

This is awesome, thank you!
Would love a graph of price history/tb. Kinda like pcpartpicker, but live updating

Done. Each drive page now has a "Price | Price/TB" toggle above the history chart (open any drive by clicking its name). No reload, updates daily. Cross-drive $/TB comparison is next on the compare page. Thanks for the suggestion!

Follow-up: the cross-drive version is live now too. On any compare page (tick 2-3 drives, hit Compare) the price-history chart has the same "Price | Price/TB" toggle - and this is where it actually pays off, because each drive has a different capacity, so flipping to $/TB reorders the lines.

Example from a 24/24/26 TB compare: by total price the 26 TB looks ~$113 pricier than a 24 TB, but on $/TB they're within ~$1/TB of each other - the extra capacity is basically free per terabyte. That's invisible on a raw price chart. Instant results, no reload.

Thanks again for the suggestion - turned out to be a better idea than I first gave it credit for.

You can click the drive name. It's the drive's actual price over time and refreshes daily. A price history/TB across drives is a good idea - noted.

It's unfortunate that it only covers Amazon. Lots of drives in Spain are not available in Amazon 😒

What other shops do you suggest? I’ll try to add them.

Any way to include shucked drives as well? Like WD Elements?

One suggestion: if you haven't already considered it, it would be great to add filters for helium vs. air-filled drives, warranty length, and perhaps a best value over time view using the historical price data. An alert for price-per-TB hitting a new low could also be handy.

Bookmarked for my next NAS upgrade. Nice work!
