I have a desktop PC (Windows 7) with 1 TB HDD which has SQL Server 2008 R2 installed. Now it is getting replaced by a laptop with 500G SSD drive. This would be first experience working with a SSD. But I have been told not to install SQL Server 2008 R2 on SSD drive. Can I buy an external hard disk and install SQL Server 2008 R2 on it? Will the database work transparently with the laptop in this way?
