I used to use an HP EX920 for my system drive and it was abysmally slow at syncs. I'd open Signal and the computer would grind to a halt while it loaded messages from group chats. After much debugging, I found out Signal was saving each message to sqlite in a transaction causing lots of syncing.

I found some bash script that looped and wrote small blocks synchronously and the HP EX920 was like 20 syncs/sec and my WD RE4 spinner was around 150. Other SSDs were much faster (it was a few years ago so can't remember the exact numbers)
