I subscribed to Google AI Pro. Why does Google Drive desktop show less than 2TB on my PC?

Google Drive for desktop may show a capacity that mirrors your local disk constraints (for example, the free space/limits of your C: drive) rather than your actual cloud allocation. This can make it look like you only have ~951GB even though the plan includes 2TB in the cloud.

How can I verify my real 2TB storage allocation?

Check your storage in a web browser on the Google One storage page. The web dashboard shows the actual storage quota assigned to your account, even if File Explorer looks incorrect.

Does the wrong capacity display mean my subscription failed?

Not necessarily. The desktop display can be misleading. If Google One shows 2TB on the web, your subscription is active and the full cloud storage is available.

Why should I subscribe through a web browser instead of an iPhone app?

App-based purchases can show different pricing or include extra store fees. To avoid confusion and confirm the campaign price, it’s safer to subscribe through a browser on the official Google One website and verify the displayed amount before paying.

What should I do if my PC still doesn’t reflect the correct storage after verification?

First confirm the quota on the Google One web dashboard. If it shows 2TB, treat the PC display as a UI/virtual-drive limitation. If it does not show 2TB, re-check the plan tied to your Google account and the purchase method (web vs app), then retry sign-in and syncing on Google Drive for desktop.

Google AI Pro: Why Google Drive Desktop Shows Wrong Storage (And How to Fix It)

December 31, 2025January 2, 2026

Google’s generative AI “Gemini” premium plan is now available at a jaw-dropping discount—58% off the regular price.

In this post, I’ll break down the details of the “2026 New Year Campaign” and share my solution to the nerve-wracking “Where’s my 2TB?!” issue I encountered right after signing up.

1. Campaign Overview: Google AI Pro for ¥14,500/year

The plan formerly known as “Gemini Advanced (Google One AI Premium)” appears to be running a promotional campaign under the new name “Google AI Pro” ahead of 2026.

Plan name: Google AI Pro (Annual Plan)
Regular price: ¥34,800/year
Campaign price: ¥14,500/year
Discount: 58% off (saving ¥20,300)

That works out to roughly ¥1,200 per month for access to cutting-edge AI and 2TB of storage.

Key Benefits

According to the promotional materials, the plan includes:

Latest model: Access to Gemini 3 Pro
Storage: 2TB on Google One
Sharing: Share with up to 5 family members
Additional features: Image generation (Nano Banana Pro), video generation (Veo), and more

The family sharing feature is particularly valuable—split among family members, it comes out to just a few hundred yen per person.

Here’s a crucial tip: If you try to subscribe through an app on your iPhone or other device, this discount may not appear (or you may be charged a higher price).

App store transactions through Apple or Google often include additional fees. Make sure to access the official Google One website through Safari, Chrome, or another browser, and confirm that you see the ¥14,500 price before completing your payment.

After completing my subscription, I excitedly checked my PC’s File Explorer (Google Drive) only to notice something was off.

“Wait… it only shows 951GB?”

I should have had 2TB (approximately 2000GB), but the display showed just 951GB. Even stranger, it was exactly the same as my C: drive (local disk) capacity.

(Actual screenshot: Both C: drive and G: drive showing the same capacity)

I started to panic—”Am I still on the free plan?” “Is this a bug?”—but after some research, I discovered this is actually normal behavior.

Why Does It Show Less?

The Google Drive desktop app (G: drive) apparently mirrors your PC’s local drive (C: drive) free space as the virtual drive capacity.

In other words, even though there’s a vast 2TB ocean available in the cloud, your PC’s entry point (cache limitations, etc.) only has 951GB available, so File Explorer displays the PC’s limit rather than your actual cloud storage.

How to Check Your Real Storage

Don’t be fooled by the PC display. To confirm your actual storage allocation, check this official page in your browser:

Google One Storage Page

When I checked there, it clearly showed “2 TB” as expected.

Summary

This campaign is definitely a great opportunity for anyone looking to get serious about using Gemini.

Subscribe through a web browser (avoid app-based purchases)
Don’t panic if your PC shows the same capacity as your C: drive
Check your real storage on the web-based management page

If you’re thinking about signing up, keep these points in mind and enjoy your new AI-powered experience!
