This is the first monthly summary of Deldur’s US cloud storage prices dataset, which went live on September 28, 2026 with 32 personal plans from 10 services. One service changed its plans during the month, and one figure in a computed table was corrected. Each change-log entry is listed below with its date and source.
Plan change
| Date | Service | Before | After | Source |
|---|---|---|---|---|
| Sept 29 | Sync.com | Personal 150GB: $4/mo, or $3.50/mo billed annually | No longer on the individual pricing page | sync.com/pricing-individual |
| Sept 29 | Sync.com | — | Personal Unlimited added: $54/mo, or $45/mo billed annually; the page’s “50% off for 1 year” promotion makes it $27/mo or $22.50/mo (“$270 billed for your first year”) | sync.com/pricing-individual |
The change was published on September 30 in its own post. In the computed tables, the 150GB row was removed from the price per terabyte table (Personal Unlimited has no single amount to divide by), and in the yearly-versus-monthly table the 150GB row was replaced by Personal Unlimited: $648.00 for twelve monthly payments against $540.00 billed annually, 16.7% less.
Correction
| Date | Where | Recorded before | Corrected to |
|---|---|---|---|
| Sept 29 | Price per terabyte table, Proton Duo, monthly billing | $9.99 | $10.00: $19.99 ÷ 2 = $9.995, which every other row rounds up; this row had been rounded down |
Qualifier added
On September 29 Proton Drive’s yearly toggle was recorded as labeling Proton Unlimited “23% OFF” and its other plans “20% OFF”. No price changed. Source: proton.me/drive/pricing.
Re-reads with no change
On September 29 Microsoft 365, Dropbox, pCloud, Proton Drive and Backblaze were re-read, as were iCloud+, Box, IDrive and Google One (signed out, on its monthly and annual tabs). Every price matched the dataset. Plans and offers shown to a signed-in Google account can differ from the public page; the dataset records the public page.
Every figure above was read from the seller’s own page on the date stated; nothing is estimated. When this was published, Deldur had no financial relationship with any company in this dataset; since October 10, 2026, one pCloud link on the dataset page is an affiliate link, as listed on the Affiliate Disclosure page. How the site works is explained on the About page, and reported errors are handled as described on the Corrections page.
