Version 11.5 of the CPU test ranked the Mac mini with 1.1 and 2.49 points (versus 1.13 and 2.58 for the iMac). In the Cinebench tests we also saw the same kind of performance figures as the iMac (Mid-2014, 21.5-inch). So DIYers looking to make a dual-drive Mac mini out of a single-drive purchase will be out of luck.
WOW ON MAC MINI 2011 UPGRADE
However even now, more than a year after Apple’s PCIe-attachment technology was introduced with 2013’s MacBook Air, there is still no third-party manufacturer able to make a drop-in replacement to upgrade capacity. Apple’s PCIe-attached flash drives are close to twice as fast as those available to Windows PCs, which still uniformly rely on the SATA Revision 3 bus protocol. That’s still the case, although there’s only one SATA connector on the logic board now, since the Fusion or Flash Drive models now work with PCIe-attached solid-state drives.

Since the optical drive was stripped from the Unibody chassis with the mid-2011 refresh, the Mac mini has had space for two 2.5in SATA drives inside.
