SSDs are fast, but expensive, & offer minimal capacity. Mechanical hard drives boast large capacity for a low price, but are much slower than an SSD. AMD Store MI technology “combines” these two types of storage into a single drive & automatically moves the data you access the most to the SSD, so you get the best of both worlds: SSD responsiveness, & mechanical hard disk capacity. You can also use up to 2GB of RAM as a last-level cache for ultra-fast data. *AMD Store MI software is only free with 400-series chipset based motherboards. Dual M.2 For SSD Equipped with M.2 slot that supports both SATA3 6 Gb/s & PCIe Gen 3 x 4 Ultra M.2 interface that pushes data transfer speeds up to 32 Gb/s, & is compatible with ASRock’s U.2 Kit for installing some of the world’s fastest U.2 PCIe Gen 3 x 4 SSD. Dual USB (Universal Serial Bus) 3.1 Gen 2 (Type-A + Type-C) This motherboard has a pair of onboard Type-A & Type-C USB (Universal Serial Bus) 3.1 Gen 2 ports built on the rear i/o for supporting next generation USB (Universal Serial Bus) 3.1 Gen 2 devices & to deliver up to 10 Gbps data transfer rates. Digi Power This motherboard uses a next generation Hybrid Digi Power design to bring precise control & smooth power. With the ensured efficient & clean power delivery to the CPU, the stability & lifespan of motherboard is also greatly enhanced. ELNA Audio Caps Who says high quality audio is only available on high-end motherboards? ASRock applied ELNA audio capacitors on mainstream & entry-level motherboards! Compared with traditional solid caps, the leakage current of ELNA audio caps is merely 3u A. This is the key to reduce noise level significantly & satisfy even the pickiest audiophiles. Solid Capacitor Design ASRock applied solid capacitors on this motherboard. With these solid caps, this motherboard is allowed to perform more stably & ensure longer lifetime.
