The Best Hard Drives for Mining Chia Cryptocurrency

10 Mins read

Although Bitcoin (BTC) and Ethereum (ETC) are still the most popular cryptocurrencies to mine, in the past few years, and even months, there have appeared new cryptocurrencies whose popularity has been steadily rising. One of these new cryptocurrencies is called Chia, and it is about to make a revolution of the way how we can mine cryptocurrencies.

Chia was developed by Bram Cohen, the world-renowned software developer who helped create the peer-to-peer BitTorrent protocol. Like Bitcoin and Ethereum, Chia has its own blockchain programming language called Chialisp. This programming language is designed to create decentralized application technologies, and make the process of mining widely accessible without expensive hardware or high electricity bills.

Compared to Bitcoin and Ethereum, which use a Proof of Work (Pow) model, Chia is based on a Proof of Space and Time (PoST) model. This means that Chia doesn’t rely on processing performance to mine, but on storage. With PoST model, users of the Chia blockchain “seed” unused space on their hard drives or SSDs by installing specialized software which stores a collection of cryptographic data on the disk as “plot” files. Users then scan the blocks to check what hash is closest to the cryptographic challenge, and then send the result off to a separate server called the “timelord”.

With this model, Chia aims to reduce the environmental impact of mining cryptocurrencies. Instead of using CPU or GPU power, Chia is designed to be mined with SSDs or HDDs. However, not all storage hard drives are suitable for mining Chia. Only the drives with large amounts of storage space are best suited for mining Chia, since Chia requires a lot of storage space for creating plot files. In this roundup, we’ll show you the best storage drives you can use to mine Chia cryptocurrency.
