[Ethereum] Ethereum Wallet downloading blocks – How to handle that memory size


I'm syncing the Ethereum node for a while now. It almost finished, but I gradually need to delete files, because it'd barely fits my disk. I only have an iMac with a 256 GB SSD and ethereum takes like 75% or so of it :/
Is this normal? Do other people struggle with this or is it just me having a small hard disk? I also have a SD card with 64 GB free, could I transfer it there? I'm also concerned not to lose my 10 ETH.

Thank you in advance!

You should use --fast option while syncing. The fast sync is really faster and the blockchain data occupies less space on your hard disk because:

Instead of processing the entire blockchain one link at a time, and replay all transactions that ever happened in history, fast syncing downloads the transaction receipts along with the blocks, and pulls an entire recent state database.

But you can't mix both normal and fast sync. Either you download the whole blockchain using fast way (--fast) or the normal way.

You need not worry about your ethers. Just backup your ethereum-wallet. Pay attention: It's always safe to keep backup before making any changes to .ethereum directory
