Re: What exact model HDD did the my Aurora R6 come with?

Also, if you just want something with a lot of storage space for cheap, you can pick up just about any 3.5" SATA hard drive. If you do, try to get something that spins at 7200 rpm and has a large cache buffer.  They also make "hybrid" drives that are mechanical with a smaller portion of solid state memory that's used to pre-load the most often accessed data. Those are a tad more expensive that plain mechanical drives, but far less costly than SSD drives.
