So it'll double in price after that. And that's on top of having to round up to the next terabyte or two. But if you want more bandwidth then it looks like it's worth considering.

Side note: It's interesting that above 2TB the deal gets steadily worse.

Where did you see the non-discount price?

I think maybe the deal looks like it gets worse because the RAM provided increases significantly.

Top left above the price in black on white text is the non discounted price. The text he is quoting is the first entry in the "faq" below.

We are pay-as-you-go and charge per GB, so you can store 1-10GB and pay nothing, 13 GB and pay $0.01/month, etc.

It scales up and handles PB of data as well.

"We designed this service to reliably hold a huge amount of data. This setup will serve you best if it’s used to store compressed data archives or backups." "Do you offer backups with this service?

Unfortunately, no. Users have to regularly back up the data themselves. " That sounds a little contradicting

If you have a lot of storage, you can rent servers for 2.86/tb (+ tax) from OVH.

I tried them in the past, speed is limited to 50mb/s (6.25MB/s)

You are missing the durability part here, leave aside the overall operational burden. I am just saying in case the drive storing your files catches fire or... simply fails.
