Update, October 25, 2026: Icedrive replaced its Pro 2 TB, Pro Plus 4 TB and Pro Max 6 TB plans with five new plans from 100 GB to 10 TB, so it no longer sells 2 TB; the lowest yearly 2 TB price on record is now $99.99 (Google One, pCloud). The cloud storage page lists 46 personal plans from 14 services; details are in its change log.
Update, October 18, 2026: Degoo, Icedrive and Tresorit were added to the dataset, each read from its own pricing page. The cloud storage page now lists 40 personal plans from 13 services; Icedrive Pro sells 2 TB for $9.99 a month or $99 a year, now the lowest yearly 2 TB price on record. The baseline figures below are from the first 10 services; every addition is in the page’s change log.
Update, September 29, 2026: Sync.com’s individual pricing page no longer lists the Personal 150GB plan ($4 a month, or $3.50 a month billed annually) and now lists Personal Unlimited at $54 a month, or $45 a month billed annually. The cloud storage dataset and its change log are updated; it still covers 32 plans from 10 services. The rest of this post describes the September 28 baseline.
Deldur’s third dataset tracks what personal cloud storage costs in the United States. On September 28, 2026 the pricing pages of ten services were read directly: Google One, iCloud+, Microsoft 365 (OneDrive), Dropbox, Box, pCloud, Proton Drive, Sync.com, IDrive and Backblaze Computer Backup. The baseline has 32 plans, each with its storage amount, its standard price when billed monthly, its standard price when billed yearly, and every promotion, struck-through figure and user-count condition the page prints. The full tables with source links are on the cloud storage prices dataset page, and every later change will be logged there with the old and new figure.
2 TB: three services at $9.99 a month, two above it
| Service | Plan | Billed monthly | Billed yearly, per month | Yearly total |
|---|---|---|---|---|
| Google One | Google AI Plus (2 TB) | $9.99 | $8.33 | $99.99 (shown on the page) |
| iCloud+ | iCloud+ 2 TB | $9.99 | — | no yearly price shown |
| pCloud | Premium Plus 2 TB | $9.99 | $8.33 | $99.99 (shown on the page) |
| Dropbox | Plus | $11.99 | $9.99 | $119.88 (12 × $9.99) |
| Proton Drive | Proton Duo | $19.99 | $14.99 | $179.88 (“Billed at $179.88 every 12 months”) |
Two terabytes is the one amount that five of the ten services sell as a single plan, which makes it the cleanest comparison in the dataset. Google One’s 2 TB plan is now sold as “Google AI Plus” and bundles Gemini features; pCloud’s annual tab shows “119.88 USD” struck through above its $99.99 price with no stated promotion period, so the displayed price is the one recorded. The other 2 TB-class offers, Microsoft 365 Family and Premium, are stated as “up to 6 TB (1 TB per person)” and are listed separately.
Ten yearly prices equal ten monthly payments plus $0.09
Twenty-five plans show both a monthly and a yearly price. Ten of them, every paid plan from Google One, Microsoft 365 and pCloud, follow the same arithmetic already seen in the streaming dataset: the yearly price equals ten monthly payments plus $0.09, so Microsoft 365 Personal is $9.99 a month or $99.99 a year, and Google One’s 100 GB plan is $1.99 a month or $19.99 a year. Google’s page calls that “Save up to $19.89” on the 2 TB plan; Microsoft’s says “Save $19.89 with a yearly plan” on Personal. The other fifteen plans spread wider: Backblaze’s $99 yearly price is 8.3% less than twelve $9 payments (the page says “Save 8%”), Box Personal Pro’s $10 a month billed annually is 28.6% less than twelve $14 payments (the page’s annual toggle says “Save 25%”), and Proton Duo’s yearly billing is 25.0% less. The full table is on the dataset page.
Price per terabyte: from $1.00 to $140.00 a month
| Service | Plan | Storage | Per TB, monthly billing | Per TB, yearly billing |
|---|---|---|---|---|
| IDrive | Personal 50 TB and 100 TB | 50 TB / 100 TB | $1.20 | $1.00 |
| IDrive | Personal 5 TB | 5 TB | $2.40 | $2.00 |
| pCloud | Ultra 10 TB | 10 TB | $3.00 | $2.50 |
| Google One | Google AI Pro (5 TB) | 5 TB | $4.00 | $3.33 |
| Google One / pCloud / iCloud+ | 2 TB plans | 2 TB | $5.00 | $4.17 (iCloud+: —) |
| Microsoft 365 | Personal | 1 TB | $9.99 | $8.33 |
| Google One / Microsoft 365 | 100 GB plans | 100 GB | $19.90 | $16.66 |
| Box | Personal Pro | 100 GB | $140.00 | $100.00 |
IDrive’s largest plans are the lowest per terabyte in the dataset at $1.00 a month on yearly billing, and its page shows a first-year discount on top (“$6.99 / month” for 5 TB, against a standard $9.99), which the dataset records as a condition rather than as the price. Box Personal Pro is the highest at $140.00 per terabyte because it sells 100 GB for $14 a month; its page lists a “5 GB file upload” limit and “15 Box Sign signature requests per month” with the plan. IDrive Mini, sold on the yearly tab only, is $0.25 a month for 100 GB, or $2.50 per terabyte.
Promotions and struck-through prices, recorded as conditions
Four pages showed a lower figure next to a higher one. Sync.com’s banner says “Save 50% for 1 year” and its 1 TB card shows $8 a month next to a struck-through $16, so the dataset records $16 as the standard price and the offer as a condition. IDrive’s yearly tab states that “The discounted price applies to the first year of the selected plan. Standard pricing will apply from the second year onward.” pCloud’s annual and lifetime tabs show struck-through figures with no stated period, so its displayed prices are recorded and the struck-through figures quoted. Box’s annual toggle says “Save 25%” and shows “$14 $10 per month”. The rule on the dataset page is the same for every service: a stated promotion period means the regular price is recorded; a struck-through figure with no period means the displayed price is.
What is not in the baseline
MEGA is left out because its pricing page shows an “Estimated price in your local currency” and says “You will be charged in euros for all transactions.” Amazon Photos is left out. Team and business plans priced per user, free tiers, and plans sold only inside an app are not in the tables.
Every figure above was read from the service’s own page on the date stated, and nothing is estimated. Prices charged through an app store can differ, and Apple’s page notes that “Residents in some U.S. states have tax added to the monthly payment due to state laws.” When this was published, Deldur had no financial relationship with any service 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.
