I was getting low on disk space so I decided to move the blockchain to an external drive with thunderbolt. I did it using Method 2 from this answer: In Mist browser how can I move the data (blockchain) to another drive on Mac OSX?
Now when I start Ethereum Wallet (Mist), the sync is extremely slow. It's been like 5 minutes and I downloaded only about 10 blocks, which is like 20x times slower than when I was downloading to internal drive.
Is there any way to make it go faster? Shouldn't it be downloading directly to the external drive? It's thunderbolt so it should be fast (40GBs), no?
