For example something like that:

It will provide you a ZFS mirror of two 5 TB 2.5 drives.

I repaste the table from the article for convenience.

    PRICE  TIME       SERVICE
     $447  5 YEAR(S)  Self Build NAS
     $567  5 YEAR(S)  Self Build NAS (assuming one of the drives failed)
    $1500  5 YEAR(S)  Amazon Drive
    $1550  5 YEAR(S)  Google One
    $1200  5 YEAR(S)  Amazon S3 Glacier Storage
    $2250  5 YEAR(S)  Backblaze B2 Cloud Storage

The Backblaze B2 prices are not correct. In the original article, it states:

"For the Backblaze B2 Cloud Storage I assumed average between upload/download price because upload is two times cheaper then download."

In fact, uploads on B2 are free, and download bandwidth is cheaper than any other supplier I know of at 1 cent per GB, with a free daily allowance of 1GB. Storage rates are 1/2 cent per GB per month, of $5/mo per TB, including redundancy.

The storage cost of 5TB for Backblaze B2 for 5 years would be $60/year or $300 for 5 years, the upload cost is free, and if you downloaded your entire 5TB each month, it would cost less than $600 over 5 years because you'd also have the 1GB/day free download allowance. HashBackup (I'm the author) uses the free B2 daily allowance to pack older backup data, which sometimes requires an download and upload cycle.

I couldn't find the upload/download bandwidth assumptions, but these numbers are way off IMO.
