Renting on the Hyperspace Network

What you need to know in order to purchase storage on Hyperspace.


Storage Pricing

The pricing of storage on Hyperspace is competitive amongst hosts.

Last Updated July 31, 2018

Notice: Because the Hyperspace network just launched late July 2018, there are not currently enough hosts available in order to successfully rent storage. The information below is carried over from Sia functionality and will still apply when renting is possible.

Storage prices on the Hyperspace network are measured in Space Cash (SPACE), the cryptocurrency used to buy and sell storage on the network. The price of one Space Cash is valued in both USD and Bitcoin (BTC), and is subject to change a little bit each day like other cryptocurrencies. Occasionally, the price of Space Cash may change significantly, especially over a long period of time.

Storage on the Hyperspace network is usually priced around the equivalent of $2 USD per Terabyte per Month. With a current Hyperspace price of $0.002 USD, you could expect to spend about 1000 SPACE a month for each terabyte you wanted to rent ($2.00 / $0.002 = 1000 SPACE).

Hosts that sell their storage on the Hyperspace network set their own pricing individually. When you rent storage on Hyperspace, you'll be interacting with several hosts, so Hyperspace will automatically pick the hosts that it finds most competitive based on a number of factors, including price. For this reason, all pricing information is only a rough estimate based on network averages.

Renting Fees

In addition to the basic cost of renting storage, there are a few other fees that you'll be subject to paying as a renter. These vary from host to host, as hosts set their own prices individually, but on average:

  • Contract Fees - When you send Space Cash (i.e. pay your host) or create storage contracts on the blockchain, it costs a very small amount to do so. Contract fees help cover these transaction fees. Contract fees are a one-time fee per contract and are usually between 1-5 SPACE.
  • Bandwidth Fees - Hosts can set pricing for both upload and download bandwidth to their server. If you plan on frequently uploading or downloading new data, these fees may stack up.

Storage Contracts

When you rent storage on Hyperspace, the contract length is set to about 3 months by default. Therefore, when you upload files, you will be charged for 3 months worth of storage at that time. Budget accordingly! For example, if storage is about 1000 SPACE/TB/Month and you plan on utilizing a full terabyte, plan to allocate at least 3000 SPACE for the cost of storage over 3 months.

Once you set an allowance (explained below), Hyperspace will start to find hosts and form contracts with them. Hyperspace currently picks hosts automatically based on a number of Host Scoring metrics, which take things like storage prices and host uptime into account. Hyperspace will form contracts with 50 hosts by default, distribute your data to 30 of them, and find new hosts automatically if any of your existing hosts go offline or lose your data. Hyperspace will also sometimes create more than 50 contracts if it finds new hosts that are more competitive (in terms of the Host Scoring metrics) than your current hosts.

Space Cash Allowance

When you rent storage on Hyperspace, you control how much storage space you use by setting a Space Cash allowance. Your allowance is basically a budget that caps your spending at or below that amount. You can set your allowance to whatever you'd like, and you can change your allowance at any time. However:

  • If you set your allowance too low, you may not be able to upload (or download) all of your data. If your allowance is set extremely low, you won't be able to form enough contracts to upload anything in the first place.
  • If you set your allowance very high, you might accidentally spend more Space Cash than you'd planned on if you frequently upload or download data. A high allowance also puts you at risk of spending more Space Cash than you want in the event Hyperspace excessively creates new contracts with hosts it thinks are more competitive, or if Hyperspace picks expensive hosts.

In any event, you'll only be charged for the storage and bandwidth that you actually use, because you're charged for the storage of each file at the time you first upload it. Trying to set your allowance close to what you actually expect to spend is the best policy, and you can adjust it later if needed.

When you set an allowance, contracts start to form immediately. Hyperspace locks up your allowance amount for the duration of the storage contract, so you'll see it start to be taken out of your wallet immediately. This will appear as several small transactions in your wallet, as Hyperspace creates contracts with hosts and locks up Space Cash in an allocation to each host. If you don't upload enough data to completely use your allowance, the amount that you didn't spend will be returned to you at the end of the contract. In other words, whatever you set your allowance to, that amount will mostly be inaccessible to you until the contract is over, even if you don't spend all of it.

Uploading, Downloading, and Maintaining Data

Important things to know about putting your data on the Hyperspace network.

Notice: Hyperspace is still in development. While rare, various renting issues have been reported that sometimes result in excessive spending of Space Cash, inability to recover data, or both. It is not currently recommended to store critical data on Hyperspace without having another backup elsewhere.

Warning: Hyperspace currently relies on local metadata stored on your renter machine to retrieve files. This means that you cannot simply upload files to the Hyperspace network and then retrieve them again from any computer, or retrieve them if your computer crashes, without also having a backup of the metadata. Additionally, metadata backups must be current - if you back up the metadata and then upload or download a file, you need to back up the metadata again. See this FAQ topic for the location of this metadata. We recommend Hyperspace for cold storage use only until this limitation is removed.

Uploading Data

Uploading data via the Hyperspace app is very easy - you simply select files or folders to upload, and they'll be on their way. Upload speeds will vary based on your internet connection and your hosts' internet connections.

As mentioned above, you're only charged for the storage that you use, and you're only charged as you use it. For that reason, you can upload as much data as you'd like, up until your allowance runs out. You can increase your allowance to continue uploading if this happens.

40 MB Atomic Filesize

Hyperspace currently has a limitation of a 40 MB atomic filesize, which means that this is the smallest file that Hyperspace can support. You can upload smaller files, but they'll be treated as if they're 40 MB and padded to that size. If you upload 20 music files at about 5 MB each, they won't take up 100 MB on Hyperspace, they'll take up 800 MB! For this reason, it's suggested that you zip smaller files together. You'll save a lot of Space Cash, especially if almost all of your files are small. There are plans to reduce the atomic filesize to closer to 100 KB, but this has not yet been implemented.

Boosting Redundancy

As you've probably read by now, Hyperspace splits your files across 30 hosts for 3x redundancy, and only 10 pieces of a file are needed to reconstruct it. For that reason, you should wait to upload any files until Hyperspace says that you have at least 30 contracts. When you upload files, they'll get to about 2x redundancy, and then show Boosting Redundancy in the File Transfer tab until they reach 3x redundancy. If your files drop below 3x redundancy, they'll be boosted again the next time you open Hyperspace. Wait until any files with red or yellow "block" icons turn to green blocks, and then you're good to go.

Downloading Data

Retrieving files is about as easy as uploading them - simply click on your file(s) in the Files section, and click the Download button that appears at the bottom of the window (the first button that looks like a cloud with a down arrow). You can download multiple files at once, though sometimes this will cause errors - try one file at a time if so.

You'll need some of your Space Cash allowance available to download your files again, because hosts also charge for download bandwidth. If your allowance is completely spent, you won't be able to recover your files, so keep that in mind.

Maintaining Data

There are three important housekeeping items that Hyperspace needs to perform when you're renting storage on the Hyperspace network:

  • Refreshing your allowance - About six weeks after your contracts are created, your allowance attempts to refill itself. The assumption is that after 6 weeks, contracts have been created and data has been uploaded, so your allowance is topped off in order to facilitate contract renewals and downloads through the rest of the contract period.
  • Renewing your contracts - Your storage contracts will renew automatically at the end of the contract period. By default, Hyperspace will attempt to renew your contract within about 3 weeks of the contract expiration date. If you started renting at the beginning of May, your 3 month contracts would expire around the end of July. Hyperspace would attempt to renew them after about the first week of July.
  • Boosting file redundancy - File redundancy is also boosted if needed, as described in the section above.

Hyperspace needs to be running with your wallet unlocked for these things to occur, so as a renter, it's a good idea to open Hyperspace at least once a month and let it run overnight to take care of miscellaneous housekeeping tasks such as these. If you simply upload files and then never open Hyperspace again, your allowance and your contracts will eventually expire and your files will be immediately deleted once your contracts are no longer valid!
