Since you didn't mention your requirements, I'll assume data integrity isn't super important. In that case, allow me to introduce you to /dev/null as a service. It's free and has unlimited capacity.

Depends for how long. Buying a used NAS with a single 1TB drive is probably cheaper over a 10 year period than subscribing to some cloud service for the same duration.

Depends what you want to do but Backblaze B2 is reasonably cheap. $6 per TB

If you want really good answers, you will need to be more specific about your requirements.

The absolute cheapest as the question is stated is to go dumpster diving for a free hard drive and host it at a friend's house, but this is likely not what you had in mind.

• Do you need backups?
• Does it need to be encrypted at rest?
• What bandwidth do you need up and down?
• Is it okay with a monthly bandwidth cap?
• what latency is okay? Is cold storage where it takes a day or more to fetch the data okay?

Hetzner storage box is 3.81€/month for 1TB.

I’ve been using Backblaze. Have no complaints

On AWS S3 Glacier Deep Archive 1TB will cost you $1/month. I use it as one of my off-site backup solutions.

Backblaze.

9/month for unlimited storage.

I'm at 4tb stored.

(preparing for inevitable downvotes) depending on how much storage you need and the flexibility you have in how you use it, Office365 includes 1TB of OneDrive storage for 6 users for somewhere around $100/yr. I use it for storing encrypted video files from my NVR and it works for my use case, but ymmv.

Another Backblaze user checking in 😁 I use their B2 service for $6/TB/mo, however they have an unlimited storage option for Windows/Mac if you're interested in that

Yet another B2 user here, I only backup things I can't afford to lose so my monthly spend isn't particularly high. I think the most I've ever paid for was around 1.5TB. One big draw for B2 is their upcoming egress policy change tomorrow: up to 3x the data stored with them is free to transfer out every day. Egress absolutely wrecks people's storage budgets a lot of the time, restoration costs can be absurd when you need to recover data.

I’ll just say this: you get what you pay for. I used pCloud a few years ago and wasn’t able to retrieve all my data, some files got corrupted (luckily I had backups). Now I use a DIY NAS and backup to B2.

OVH is quite cheap (£0.0024/GB-month)

OneDrive with Microsoft 365 Family subscription. There are several deals for 50€ per 15 Month for 1TB per Account. Since it is the family subscription you'll get up to 6 Accounts. So it is 3.33€ for 6TB or 0.55€ per TB.

Does anyone use Proton for storage?

I've been contemplating hopping onto their offerings once Proton pass has added some more features.

Hetzner's Storage Box is quite cheap

I've used Sync.com for awhile now with few issues. 1TB is about $6 a month, 2TB around $8 a month.

iDrive E2 is $40 a year for 1TB S3 compatible storage and they have promotions quite often. As always with cheap storage don't rely on it and have a local NAS but it's handy for offsite. I've just transferred out of Wasabi, who were cheap but are less so now.

I'm using iDrive. Quite cheap and if you want an S3 interface you can check their enterprise e2 tier.

Check out Hetzner Storage Box. I've got 20TB for my Jellyfin library and it's $50/mo.

Edit: use rclone to mount it as a network drive on your desktop.

Edit 2: Just checked and it's $40/month

Never worry about backups or lost data etc, as the provider would take care of it

This is not how it works. You still have to backup your data!

Your account can be closed due to various reasons, you accidentally delete files, some malware deletes files without you noticing it before it is too late.

A friend of mine lost some important data because of the ovh server container fire incident. Ovh had no backups.
