How can I run Bitcoin Core on a laptop that doesn't have much storage? Is using an external hard drive for the data directory a viable option? Any tips I should know?

Yeah, totally possible! You can use an external hard drive for the data directory. Just make sure to set it manually since Bitcoin Core won’t automatically recognize it. When launching the client, just point it to the external drive instead of your main one. This video here might clarify things.
1. Try using pruned mode. 2. Swap the storage drive with a bigger one internally if you can.
You just need to let Bitcoin Core know where the data should go. Just keep in mind that losing power or disconnecting the drive suddenly could mess things up.
Not only possible, but highly recommended. It speeds up the sync process and reduces stress on your main drive.
Really, go for an SSD over an HDD. It makes the initial sync much quicker. Don’t forget to adjust your bitcoin.conf file too.

What you said makes sense. Low storage is manageable. Using pruning means you only keep what you need, following your settings. Add this line in bitcoin.conf to set the limit.
Absolutely, external drives are a solid choice for storing blockchain data. Just choose one that suits your needs and keep it connected.
Thanks a lot for everyone’s help!
Why go through all this? Just buy a used laptop that can fit an SSD. I found a nice one for under 300 bucks on eBay in a minute.

Seriously, the easiest fix is to upgrade your internal drive. It’s not hard at all.
Yeah, running Bitcoin Core on limited storage does require some tweaks. Pruning helps by keeping only the latest blocks. Just set the limit in your bitcoin.conf.
For sure, external drives are great, but they must stay connected to avoid corruption. Bitcoin Core takes its sweet time cleaning up, so don’t just yank it out.

Your perspective is really insightful! A used laptop with a decent SSD is a good idea.
I can’t speak for everywhere, but in my area, you can find refurbished business laptops that last longer and are easier to upgrade.
True! Refurbished laptops can be a solid choice. They tend to be durable and often easier to fix compared to consumer models.

But how long do refurbished ones really last? Aren’t they bound to break faster than new ones?
I’ve been using a refurbished Dell Latitude since 2017, and it’s still running well. The battery's holding up too, thanks to some smart management.
Look for reliable refurbishers who ensure quality. They usually check the components and replace what's necessary.
Where do you find good refurbishers though? Any tips?

eBay has tons of good deals on used laptops. Just check the seller ratings.
Or just wipe it and install your favorite OS. I prefer a clean slate.
