Frequently Asked Questions
Where do these prices come from?
We use Aliexpress site to retrieve product information across several categories. We'll then filter, parse, and format the product listings.
How often is this site updated?
Prices updated every 6 hours.
How is the data processed?
First, each product name is parsed to determine capacity, quantity, and disk type. We've found this to be more reliable than trusting the product attributes returned by the API. Each product is compared against a listing we maintain of corrections, known fakes, and improbable listings, such as $0.001/GB microSD cards. Once filtered, each product's offers are examined to determine the lowest new and used prices currently available. Finally, we compute price per gigabyte and sort the results.
Why doesn't this product appear on your site?
We aggressively filter our product list to remove duplicates, fake products, spam, and out of stock listings. This results in the removal of some percentage 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 API and cannot retrieve more than certain number of 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 contact us
Why shouldn't I buy the cheapest drive?
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.
