We need to correct an assumption here: none of the leading E Ink notebooks, Kindle Scribe, reMarkable, XPPen, BOOX, currently ship with a user-accessible microSD or removable storage slot as a standard feature across the board. What buyers actually control is which fixed storage tier they purchase.
So instead of a false expandable-storage roundup, we ranked these by their largest available fixed storage tier, since that's the real lever for anyone who needs more room for notes, PDFs, or books.

How We Chose These Digital Notebooks with Expandable Storage
Each pick was assessed across 4 criteria weighted for real-world use.
- Honest disclosure of no removable storage
- We verified no current leading E Ink notebook ships with a user-accessible microSD or removable card slot as standard, and said so directly.
- Fixed storage tier as the real lever
- We ranked by the largest available fixed storage configuration for each product line, since that's what buyers actually control.
- We compared refurbished versus new pricing at the same storage tier, since the value gap can be significant.
- Cloud/Android flexibility as a partial substitute
- We noted where Android-based devices offer more flexible cloud storage app options that can extend practical usable capacity.
What to Look for in a Digital Notebook with Expandable Storage
Key buying criteria so you get the right fit the first time.
Check whether AI or handwriting-conversion features are included or require a subscription
Digital notebook brands take different approaches to their software features: some bundle handwriting-to-text conversion, document summarization, and cloud sync into the purchase price, while others, most notably reMarkable's Connect plan, gate the more advanced versions of these same features behind an ongoing monthly subscription that continues costing money long after the initial purchase.
This is a real total-cost-of-ownership difference that a one-time hardware price comparison completely misses, since a cheaper device with a required subscription can cost more over two or three years than a pricier device with everything included upfront.
Check the specific listing and manufacturer's website for whether the features you actually want are included in the base purchase or require an ongoing plan, and factor that recurring cost into your real comparison.
Understand that "AI" and "handwriting conversion" mean different things across different devices
The marketing term "AI" gets applied to several different features across this product category: converting your handwriting into typed text, summarizing a long document or your own notes, organizing notes automatically by topic, or simply offering a chatbot-style writing assistant, and a device marketed heavily around "AI" doesn't necessarily include all, or even most, of these specific capabilities.
This matters because two devices can both claim AI features while actually doing completely different things, so a buyer specifically wanting handwriting-to-text conversion could end up with a device whose "AI" feature is actually a summarization tool that doesn't address their actual need at all.
Read the specific feature list rather than the marketing headline, and confirm the device does the exact task you need (handwriting conversion specifically, not just "AI" generally) before buying.
Confirm the stylus situation: included, sold separately, or requiring a specific model
Some digital notebooks include a compatible stylus in the box as part of the purchase price, while others sell the device and stylus as separate purchases, or require a specific proprietary stylus model that isn't interchangeable with a generic capacitive pen, and this distinction can add a meaningful hidden cost on top of the listed device price if you assumed a stylus was included.
Beyond just the cost, stylus quality itself varies in pressure sensitivity, tilt detection, and palm rejection quality, features that matter significantly more for sketching and detailed note-taking than for simple text entry.
Check the listing specifically for whether a stylus ships in the box, and if writing feel matters to you, look for mentions of pressure levels and palm rejection quality rather than assuming any included stylus performs the same as another.
Check the export and sync ecosystem, since notes trapped on one device have limited long-term value
A digital notebook's real usefulness depends heavily on getting your notes and documents off the device and into a format you can actually use elsewhere, whether that's cloud sync to a phone or computer, export to PDF or Word, or direct integration with a note-taking platform like OneNote or Google Drive, and devices differ meaningfully in which of these paths they actually support natively versus not at all.
This matters concretely for anyone using the device for professional or academic work where notes need to end up in a shared document, an email, or a specific software ecosystem, since a device with limited export options can leave your handwritten notes effectively stranded on the device itself.
Check the manufacturer's stated export formats and sync options against the specific software or workflow you actually need to feed notes into, rather than assuming any device syncs to everything.
Weigh review volume against star rating, especially for newer AI-branded entrants
Established digital notebook brands with years on the market carry review counts in the thousands, giving genuine statistical confidence in their ratings, while newer devices, especially ones marketing themselves heavily around AI features to ride current interest in the category, sometimes carry only a few dozen or a few hundred reviews, which is a meaningfully thinner sample to judge long-term reliability and whether the marketed features actually work as claimed.
This doesn't mean a newer, less-reviewed device is automatically worse, but it does mean the claims on its listing carry less independently verified weight than a device with years of real-world feedback behind it.
When comparing an established brand against a newer AI-branded entrant, check both the star rating and the review count together, and weigh a smaller but heavily AI-marketed device's claims more skeptically until more real-world feedback accumulates.

AI Features Included vs Subscription-Gated
- AI note tools come with the purchase price, no ongoing cost. In this comparison: check each listing's terms directly.
- Advanced AI features require an ongoing paid plan on top of the hardware price. In this comparison: none explicitly confirmed in this specific roundup, check the listing before assuming.
Check each specific listing for current subscription terms, since these change over time.

Frequently Asked Questions
Do any digital notebooks have a removable microSD card slot?
Not as a standard feature on the leading current devices we checked, Kindle Scribe, reMarkable, XPPen, and BOOX all use fixed internal storage.
What's the best way to get more storage?
Choose the largest fixed storage tier at purchase, since you generally can't add capacity afterward. The 64GB configurations are the largest we found.
Is refurbished a good way to get more storage for less?
Yes, the Like-New 64GB Kindle Scribe costs less than half the price of the new Colorsoft for the same storage tier.
Does Android help with storage limitations?
Indirectly, the BOOX Note Air 5 C's Android base allows more flexible cloud storage app options, which can supplement fixed on-device capacity.
How much storage do I actually need?
Handwritten notes use very little space. If you plan to store a large PDF or book library, prioritize the 64GB tier over 16GB or 32GB options.
