M.2 vs mSATA case study – Crucial M500 240GB & Plextor M6e 256GB
Gigabyte equipped the Z97X-UD5H with 8 SATA 3 ports – 6 native from the PCH and 2 provided by an additional 3rd party controller. If you have a SATA Express storage device, you are willing to give up 2 regular SATA ports and the M.2 port is not in use then you can use the available SATA Express port.
On the backpanel we can find 6 USB 3.0 ports, 2 USB 2.0 ports, one PS/2 for keyboard or mouse, two Gigabit LAN ports (Intel i217v & Killer E2200), audio card outputs and inputs and also 3 video outputs (DVI-I, D-SUB and HDMI).
The CPU VRM on the Z97X-UD5H is based on an Internatonal Rectifier IR3563B which controls the 12 phases through IR3598 drivers configured in doubler mode. The MOSFETs are SiRA12 PowerPAK’s from Vishay, each phase having one high-side and one low-side.
The memory VRM has two phases and is also based on the same MOSFET’s and chokes as the CPU VRM, the only difference being that each phase has three SiFA12 PowerPAK’s. All the heatsinks are mounted using spring loaded screws and all the solid caps come from Nippon Chemicon.
