The Best Storage for Chia Farming: Building the optimal storage farm

The Best Storage for Chia Farming: Building the optimal storage farm

Chia is a relatively new cryptocurrency that’s taken the world by storm (enough so to cause storage shortages in China) and it isn’t even tradeable yet. In other words, it’s a very young cryptocurrency with a seemingly high potential for appreciation.

If you’re unfamiliar with Chia, check out our guide to farming Chia, which covers a lot of common questions in addition to walking you through the process of setting up your PC for mining. Before we discuss what the best storage for Chia mining is, it’s important to understand the basics of the farming process.

How does Chia farming work?

In Chia mining, there are two basic functions, which we’ll cover below:


Plotting is the first step of the Chia farming process. During Plotting, you create a .PLOT file on a storage drive. The bigger the .PLOT file, the higher percentage of the total storage you make up and the higher your chances of acquiring Chia.

Basically, plot size is similar to a hashrate in other forms of crypto mining, such as Bitcoin and Ethereum. The more, the merrier.

Within the plotting process, there are two directories (or storage locations):

  • The Temporary Directory is where storage is temporarily used in order to write the .PLOT file. Once the .PLOT file is written, the temporary storage drive’s space is freed up and you can use it to write more .PLOT files.
  • The Final Directory is the final destination for the .PLOT file. Plots are permanent until deleted; this means that once you create a plot it will stay there and be farmed indefinitely.

The temporary and final directory can be on the same storage drive. For example, if you only have one drive you can still farm Chia. It’s not the most efficient way to do it, but you can use the drive as both the temporary and final directory.

Essentially, the temporary directory can be reused indefinitely to plot to as many desired final directories as possible. You could, in theory, create thousands of gigabytes worth of Chia plots across multiple hard drives using the same SSD as your temporary directory (as long as it doesn’t wear out).

Plotting and farming Chia
Plotting and Farming


Farming is the process by which you actually earn Chia. Once you’ve created at least one plot, it will automatically begin to be farmed. Farming is far less resource-intensive than plotting, since it doesn’t use a significant amount of RAM.

What’s the best farming model?

When creating a Chia farm, you’ll ideally have at least one high-speed NVMe drive for plotting and one or more hard drives to store the .PLOT files.

This works because the NVMe can create the .PLOT file much more quickly than a hard drive, since its read/write speeds will be significantly faster than any hard drive (or even SATA SSD). In our experience, it takes several days with a hard drive to plot a file than an NVMe could handle in several hours.

On the other hand, the end goal of Chia farming (at least, if you want to turn a profit) is to have the largest amount of storage space in .PLOT files possible. Since drive speed doesn’t matter once the plots are created, hard drives are by far the best storage solution.

The most cost-efficient hard drives offer storage at a cost of less than 2 cents per gigabyte. That’s pretty incredible!

How to maximize plotting efficiency (understanding NAND flash types)

When selecting a temporary storage drive for plotting, it’s incredibly important to understand the impact of NAND memory type on a drive’s performance.

Almost all consumer drives available right now are either TLC (triple-level cell) or QLC (quad-level cell) NAND. The “triple” and “quad” refer to how many bits of data are stored in a single NAND memory cell (which you can think of as the most basic unit of storage in a drive).

In addition to TLC and QLC, there also exists two other major flash types: SLC and MLC. These are “single-level cell” and “multi-level cell” (one bit and two bits per cell, respectively).

This may seem a bit complicated but hang in there, because this information is essential to ensuring maximum plotting efficiency.

The more bits stored per cell, the more affordable the storage can be. This is why TLC and QLC are the most popular; manufacturers can create higher-capacity drives for less money.

The downside to these cheaper drives is that they much slower write speeds in general (this results from storing more bits per cell).

Manufacturers use a method called SLC caching, which basically uses free storage space to simulate single-level cells. This enables QLC drives to achieve the write speeds of an SLC drive, but of course this is only possible when a good bit of storage is free. Every drive has a set SLC cache size and once the cache is full, the drive begins writing at TLC/QLC speeds.

The important takeaway is that TLC or QLC drives will be effective for plotting, but only if your plot doesn’t exceed the SLC cache size.

With this in mind, the most efficient plotting method for non-enterprise drives is to create large numbers of K32 plots (these are the ones that require 239 GiB of temporary storage). With even a 1TB SSD, you’ll leave a large portion of your storage full, ensuring your TLC or QLC drive can maintain the fastest possible write speeds.

If you’re wondering why we recommend K32 and not the much-smaller K25, it’s because K32 is the minimum allowed size for mainnet, as per Chia Blockchain.

The Best NVME (Temporary Drive) for Chia Farming

One last facet of plotting that needs to be considered is that the temporary drive requires more storage space than the final .PLOT file takes up. If that’s confusing, for example:

If you want to create a K32 plot (and it’s highly recommended that you stick exclusively to K32s), it will take up 101.4GiB in the final directory, but you’ll need 239 GiB of free space on your temporary drive.

If you want to plot several K32s in parallel you’ll need that much more temporary storage. For six parallel K32s you need at least 239 x 4 = 1434 GiB (that’s about 1540 GB).

With this in mind, you probably want to get a temporary drive that can create as many plots in parallel as your RAM and CPU can support. If you don’t have a system built yet and don’t know where to start, you can check out farming system recommendations.

If you already have a farming rig, the easiest way to figure this out is to divide your RAM by 4 and your CPU thread count by two. This derives from the fact that you need approximately 4GB of RAM and 2 CPU threads per parallel plot.

For instance, say you have a Core i5-11400 and 32GB of RAM. If you didn’t know, you could look up the 11400’s thread count and easily find out it has 12 threads.

We divide this number by two (the number of threads per plot), which gives us six. Likewise with the RAM, we take 32/4, which gives us eight. So our maximum simultaneous plotting capacity is six K32s.

Once you’ve determined your maximum plotting capacity as determined by your CPU and RAM, just select a temporary drive that can handle that number of parallel plots. In the above example the max was six, so we’d want an NVMe that can handle six K32s.

That’s pretty easy to calculate. Just multiply the amount of temporary space required for a K32 by six. That gives us 239 GiB x 6 = 1434 GiB. Converted to standard GB, that’s around 1540, so you’ll need a 2TB drive for this task.

If you have over 16GB of RAM or an i5/Ryzen 5 processor and above, we definitely recommend a 2TB NVMe. You’ll be able to plot much more efficiently when doing it in parallel with six or more at a time.

The Best NVMe Drive for Large-Scale Chia Plotting: WD Gold 4TB

Every storage drive falls into one of two major categories: consumer or enterprise-grade. Consumer drives offer more than enough performance for the vast majority of users, and cost a lot less than their enterprise counterparts.

Enterprise drives are useful because they offer much higher sustained writing speeds than consumer drives. For example, a consumer SSD rated for max write speeds of 3000 MB/s will probably write at around 500 MB/s when writing for long periods of time. It can’t sustain its maximum read speed for long.

On the other hand, an enterprise SSD with the same max write speed could write at 1000 or 1500 MB/s, and could sustain those speeds indefinitely.

These numbers are just examples to illustrate a point: enterprise drives write much faster over the long-term.

If you’re running a pretty sizeable farming operation, you should probably opt for one of these enterprise drives, like the WD Gold. You’ll be able to create plots much more quickly with it.

Additionally, enterprise drives are rated for much higher TBW, which basically means they have a higher endurance. They’ll be able to write more terabytes of data before they kick the bucket. Durability shouldn’t really be an issue, since even consumer drives frequently have a durability rating of over 1500 TBW.

We selected the WD Gold because it’s one of the best, if not the best, enterprise-grade drives on the market. We chose the 4GB version because with this you’ll be able to plot the largest plot size (a K35), which only requires 2.175 GiB of temporary storage. If you’re trying to plot at the fastest possible speeds, this may be the best temporary drive for you.

The Best 2TB NVMe for Chia Plotting: Inland Platinum

Inland’s Platinum SSDs have essentially the same read/write speeds as the CS3030 (3400/3000), and they’re more cost efficient if you’re willing to spend more in total. If you’re dubious of non-name-brand storage drives, Corsair’s MP400 is second-runner-up. It has the same data transfer speeds, but costs a little bit more.

The Best 1TB NVMe for Chia Plotting: PNY CS3030

The CS3030 is the fastest NVMe available at a reasonable price, making it the best temporary storage for Chia if you opt for the 1TB size. It has respective read and write speeds of 3500 and 3000 MB/s, which is over twice as fast as drives that are only $20 cheaper. Essentially, the CS3030 has the best price to performance ratio of any NVMe.

The Best Hard Drive (Final Drive) for Chia Farming

There is really only one quality that is needed in the optimal Chia-farming final drive. This is high storage capacity at a cheap price.

If you’re farming on an absolutely massive scale, you may want to buy the highest-capacity hard drives possible so as to take up as little space as possible.

In any other scenario, you’re probably best off buying the storage that costs the least amount per unit.

The Best High-Capacity Hard Drive (Final Drive) for Chia Farming: Seagate Exos X18 18TB

This is the biggest drive you’ll be able to find, and is pretty cheap on a per-gigabyte basis. As mentioned earlier, if you’re trying to fit the maximum amount of storage into a confined space, this 18TB drive may be the one for you.

The Best Cost-Efficient Hard Drive (Final Drive) for Chia Farming: Seagate BarraCuda 8TB

Seagate makes cheap storage, and it’s of reputable quality. What more needs to be said? The 8TB model is the cheapest storage known to man — it comes in at a whopping 1.8 cents per gigabyte.

    What Happens When Final Destination Drive Gets Full? Should We Add Another Drive For Farming And Let The Existing One Keeps On Farming?

    1. Barry Gates

      Yes. Once you’ve maxed out the storage on one drive, you have to add another drive if you want to keep adding farming space.

    i want to now if it make sens to use Ryzen with 32 Threads ans 2 X (M.2. 8TB as temporary= 1 For temporary Farming and 1 For Plot-Transfer M.2. to Final Directory) , because i would like to start 13 ~ 15 Plots in Parallel.

    Do you things in this form im effizient??

    1. Barry Gates

      You’ll need 64GB of RAM to plot that many in parallel (4GB per plot), just something to keep in mind. I’m not sure I entirely follow, do you intend on using two separate 8TB NVMes as temp drives at the same time?

    Hi Barry,
    Very good article. I`ve got a fast question: so with 16GB of RAM I can do 4 plots in parallel at the same time. So I can have around 120 101.4GiB farming plots with 14TB. so the best idea would be to add 2TB NVMe to max the plot creation, correct? what I mean having 4 parallel with, lets say 85 minutes gap between them and then add 1 plot in a queue. I`m completely new if it comes to mining/farming.

    1. Barry Gates


      A k32 plot will take up approximately 257 GB, so four would take up 1028 GB. In other words 1028GB is the max temporary space you’re going to use plotting k32’s as long as you’re limited to 4 plots by your RAM.

      So you’re right, a 2TB NVMe would be your best bet for fastest plotting if you want to maximize efficiency. Good luck!


    What is the optimal way to format the disks (allocation units)?

    1. Barry Gates

      Set them up as a one-partion Simple Volume in Windows Settings.

      To do this just search “create and format hard disk partitions” and create the new volume there.

      1. Niko Alviky

        I love this Article, please give me advice for formating the harddisk. GPT or MBR, or other advice maybe? My HDD is seagate. thank you so much Mr Barry

      2. Barry Gates

        GPT is technically a little better, so I’d go with that. Just create a simple volume with the entire space of the disk, that’s the best way to allocate storage.
