For the past few years I've been building a huge NAS storage with over 1PB in size. As its growing over time, buying new drives is always a tedious process. It's hard to tell whether a drive is CMR or not. Some manufacturers are known for sneaking in SMR into their NAS line of disks. There's always multiple browser tabs open and very often they are in total disagreement.

So, first I built a table, which turned into this website. It fetches daily prices for all NAS disks from Amazon, and covers 8 different regions. It has price history, shows if a disk is a CMR or SMR, and its failure rates (I had to compile tons of raw data from Backblaze public Drive Stats).

It has both NAS hard drives and SSD, and you can see price per terabyte for each drive listed.

It is free and it needs no login. I worked hard to keep the data honest, so only new drives are listed and all scalpers and grey market was removed. The whole dataset is also available for free under CC BY 4.0 license on the Data page (Backblaze part is attributed as needed). It's also published on Github.

Your feedback is very welcome. If you notice anything missing or wrong, please let me know, and I'll fix it asap. Best features on the website were added because users asked for them, so any suggestions are welcome!

I really like it's free, no log in or ads, only thing I’d love to see is some kind of “best deal right now” view by region/capacity. Great project overall will bookmark it for later usage, thanks!

pretty useful stuff, man. thanks for sharing
