I am going to install a new SQL server 2008 instance on my machine. My machine have one 7200rpm 500GB SATA Disk (C:OS) and one Intel X25-G2 80GB SSD(D:).

Microsoft said I have an option to place following directories in different disk. So I plan to place User database & Temp DB on SSD and rest of it on traditional disk. Is it a good choice for gaining a performance boost in fast SSD?

Data root directory :C:\Program Files\Microsoft SQL Server

---

User database directory D:\Data

---

User log directory C:\Logs

---

Temp DB directory D:\TempDB

---

Temp Log directory C:\TempDB

---

Backup directory C:\Backups
