Ideal System Spec To Run Bitcoin Core

[Slot Kid]

Hi, I have been running various versions of Bitcoin Core for 10 years. I used to use it as a wallet to store my Bitcoin with passphrase protected wallet.dat but have since begun using cold storage. I still run Bitcoin Core, haven’t upgraded since 0.26.0

It runs fine when it’s open but I was just wondering what’s the ideal system spec these days to comfortably run it 24/7?

It freezes quite a bit when syncing if I ever turn the computer off and have to open it again. It can hang on Starting Network Threads or Done Loading for 10-15 minutes. This didn’t used to happen. This old laptop I use only has 1TB of storage and the blockchain is getting bigger and bigger.

Would the following be sufficient to flawlessly run Bitcoin Core on a new laptop:

 128 GB RAM

 2 TB SSD

 16 Core

Some links or recommendations for different capable laptops would be greatly appreciated, thanks.

Any Laptop could work as long as they meet the spec suitable to run Bitcoin core but most persons use a dedicated laptop - raspberry pi. Whereby the spec you mentioned is far greater to that of raspberry Pi 4 or 5 (64-bit).

This system spec is more than enough to run your Bitcoin core 24/7.

If you are still having issues when you have this system spec, then try checking the performance level of the CPU. Sometimes high usage will slow the system down, maybe you are running other solidarity programs.

If you are planning on getting this spec of laptop, then it is very much enough, though you are not really backward in update but I think updating your Bitcoin might help here.
By the way what spec of laptop/pc were you using before? Also, I think this link might be helpful to you https://learnmeabitcoin.com/technical/networking/node/

8 GB RAM

1 TB SSD

Internet speed is fast but often on sync very slow.

128 GB of RAM is overkill and doesn't need to spend that much on hardware. In my opinion, laptops with 32GB is more than enough to handle intense tasks, including running core 24/7 along with Mempool.space interface running in parallel.

If I am not wrong picking the right hardware combination along with the optimal cooling system get the best performance on average running time instead of going for the most powerful one, which is wasting more money than needed for the task.

This is enough. I'm curious are you running full node?
If yes, do you use your pc for any other heavy task?
Although, additional spec of your laptop, like: processor and gen; might affect this.

Actually, having an SSD has a big speed impact on the PC with 16 GB of RAM, which would be better if you are doing other tasks on the PC while syncing.
I don't know if you do a heavy task. I am sure it's going to affect the syncing process.

If you are doing a heavy task on your PC, you'd better make a separate node if you don't want to slow down the node. I suggest having a mini PC with m.2 ssd and 16gb of ram installed with Linux is a great option.

I run Bitcoin Core node headless on one or sometimes two Raspi 4B with 8GiB RAM, depending on what I want to do. Usually I also run Electrs or Fulcrum as personal Electrum servers.

Bitcoin Core as full unpruned node and Electrs now barely fit on a 1TB SSD for the Raspi 4B. Fulcrum fully synced as noticeably faster Electrum server doesn't fit with unpruned Bitcoin Core anymore on a 1TB SSD but needs a 2TB SSD which is then comfortably big enough for quite some time in the future.

For me this is fast enough to use an Electrum or Sparrow wallet connected to my personal Electrum server (I care about address privacy of my wallets).

The Raspi 4B with 8GiB can run with no issues 24/7, consumes ~4-5W on average (or even little less than that) with a suitable USB3-SATA-adaptor for a low power SATA SSD (the Raspi 4B has a total power budget for all USB ports combined of ~6W, power hungry SSDs will eventually give you headaches and unstable operation).

Because my Bitcoin Core node and Electrum server run 24/7/365, a low power consumption during operation has priority for me.

If I had to buy a Raspi now, I'd take a Raspi 5 with 16GiB RAM and attach a 2TB NVMe M.2 SSD with a suitable daughter board. This setup is faster and should work fine 24/7 reliably. You could also run it with GUI if you need to.

Almost any Mini-PC should also work fine and you have more options for RAM size and how much processing umpf you want.
