We use Amazon's Product Advertising API to retrieve product information.
Prices are updated every four hours.
We aggressively filter our product list to remove duplicates, fake products, spam, and out of stock listings. This results in the removal of approximately 1.9% of all listings.
In some cases, our algorithms cannot correctly classify products into a known category, so they may be unintentionally excluded. The list of unclassifiable products is reviewed by a human editor semi-regularly.
We are also limited by the functionality of the Product Advertising API and cannot retrieve more than 100 items per query and can only perform a limited number of queries per day. This leads to the exclusion of many products with a low sales ranking. If there is a product that you believe should be listed, please email its ASIN to [email protected]
Amazon's affiliate program and API access is managed by a different team in each country and some of these teams do not believe that processing, filtering, sorting, editing, and removal of counterfeit products is valuable to the customer. The following marketplaces have threatened or suspended our accounts and are unlikely to return to diskprices.com without clear policy changes from Amazon: amazon.jp, amazon.nl, amazon.it, amazon.sg.
Pricing reflects a large number of factors including warranty duration, intended market, manufacturing processes, expected performance, and inventory levels. If you're building a RAID array where you can tolerate some failure and don't need fast seeks, cheap unreliable drives might be acceptable. Backblaze's blog has some excellent posts that enumerate these factors. For information about specific drive models and technologies, AnandTech has very in-depth reviews.
The prices listed here don't include shipping and taxes, as we don't know where you live. The majority of these listings include free shipping, especially if you have Amazon Prime but make sure to check shipping costs before placing an order.
