Show HN: TerabyteDeals – Compare storage prices by $/TB

21•vektor888•1h ago

I built a simple tool to compare hard drive and SSD prices by price-per-terabyte.

I kept having to calculate $/TB manually when shopping for NAS drives, so I made this to save myself the trouble.

It pulls prices from Amazon (US, CA, AU, and EU stores), calculates $/TB, and lets you filter by drive type, interface, form factor, and capacity.

Nothing fancy — just a sortable table updated daily.

Any feedback is more than welcome, I hope someone will find it useful!

If only you had known about diskprices.com you could've saved yourself the trouble.

Oh well... nevertheless, it was a fun project to work on, and it still is!

I am planning to add some aggregated statistics (e.g. price trends by brand/category)

I guess you didn't read the amazon tos then. Price trends and history is not allowed.

Not for this specific use case.

Are platforms like Keepa violating Amazon's ToS then?

superkuh•5m ago

Ah, from the wording ("pull") I assumed you were using the API. You use your own user-agent to access the site(s) and collect prices then? Do you have any trouble getting blocked doing that? Is it some headless chrome controlled programatically?

ToS are not enforceable if you don't use an official product feed from Amazon in this case. As shown by thousands of companies providing exactly this service for competitor analysis.

Or just quickly pivot to RAM prices!

The prices don't seem accurate on the ones I checked. Maybe they were a few months ago, but there's been a lot of stock shortages, especially for larger HDDs, and it's been driving up prices.

Thanks for the input!

This should be the price as shown in the product listings for the category. Perhaps, depending on product availability, you are shown different prices on the product page.

I will take a better look into this, but I can confirm that this data is very recent (about 4-5 hours ago), definitely not months old

At least for France prices are wildly innacurate. The actual ones are 150 to 200% the price on the table.

I checked 6 to 8 TB HDDs.

Thanks for the feedback!

These prices are 5-6 hours old. While working on this site, I noticed that Amazon pricing can be very dynamic.

Moreover, it could be that Amazon is returning the retail price, but because of current availability, once you land on the product page, you are shown prices from a different seller

Every price i checked on Amazon.de was wrong on your website, this is totally useless! Often the real price is like 300% higher

vektor888•26m ago

Thanks for the input!

As I mentioned to other users, Amazon's pricing seems to be quite dynamic. This data is just 4-5 hours old, but it already seems quite stale.

Note taken that it should be updated more frequently!

Feedback:

Interesting. Glad there was a drop down to pick a bunch of different sources. I was expecting it to be US central but was happy when I saw I could search for amazon.co.uk

An ability to search for NAS drives, even if it's just a substring search within the product name, would be great.

Also a search on drive speed. I'm not interested in 5400rpm drives, only 7200rpm+.

(I'm looking for a bunch of 7200rpm drives that are NAS rated, so I'm not interested in generic consumer grade 5400rpm drives right now.)
