Records are stored all over the place and are rarely sequential unless you're selecting them in the identical order they were written - assuming they were written sequentially to begin with. Even with HDD emulation the RAM disk is still several times faster than an SSD drive. In fact it's

Using RAM Disk for SQL Server tempDB: possible issues

I've been using 12GB RamDisk installed on a Hyper-V VM (90GB RAM) for use as the tempDb for SQL Server. In tests it's done a great job in speeding up large queries. However, in recent more intensive tests we've noticed queries taking a very long time that we end up aborting. We're trying to discover where the issue is - it could be anything. The RamDisk option to emulate a hard disk is disable
