Modders-Inc posted a review on the AMD StoreMI Tiered Storage
A quote from the article:
With the release of Ryzen second-generation CPUs and X470 chipsets, AMD unveiled a new hybrid storage solution called StoreMI, that may just put an end to choosing speed or size when it comes to your data storage.AMD StoreMI Tiered Storage Review
When it comes to storage, there seems to be a constantly sliding scale between capacity, performance, and price. This has become more drastic ever since the introduction of consumer-level Solid State Drives. In capacities up to 2TB, they are beginning to hold enough data to keep most people happy, but at prices few can afford, with SATA drives hovering around $450, and nVME starting at $800. Compare this to 10TB mechanical drives starting as low as $310, or even 4TB drives for under $100.
You can start to see how difficult prioritizing your storage needs can be in the current market.
