In the first part of this article, we reviewed different kinds of the most commonly used modern SSDs (M.2, PCI-E, NVMe devices) and talked about acquisition of these devices. In this part of the article, we will talk about external SSDs and eMMC and will cover trimming of eMMC.
eMMC is a storage specification for flash-based non-volatile storage used in many compact and mobile devices. You will find eMMC storage in most Android smartphones, Android and Windows tablets, and in some of the less expensive Windows convertibles, low-end netbooks and ultra-portable devices, particularly those equipped with smaller displays and Intel Atom CPUs. eMMC storage has a lot in common with SD cards, and lacks sophistication and parallelism of SSD drives.
