Bests & Worsts Reviews from Amazon

Why get it: - Much faster than SATA SSD - Great performance-per-watt and low idle power. Great for laptops. - Great Crucial (Micron) support / reliability /warranty (I used their support once on a M4 SSD) - Plenty of endurance for typical consumer use cases - Free Acronis True Image SW to clone old drive into this new SSD Why skip it: - Not suitable for server workloads (e.g. highly transactional DBs) or people that, on a daily base, write >25GB worth of data Performance summary: - Data Rate: ~2.5X faster than SATA drives, ~40% less than high-end PCIe NVMe in heavy-duty workloads - Latency: ~¼ lower than SATA drives, ~40% higher than high-end PCIe NVMe in heavy-duty workloads - On typical consumer workloads (mixed random R/W low queue depth), there is no noticeable difference relative to a high-end PCIe NVMe === UPDATE 7/20/2019 === I bought a second one (1TB). Installed on my son's ASUS ROG Zephyrus G GA502 gaming laptop (for a total of 1.5TB using the free M.2 slot). Now there is plenty of space for games (512GB gets full quickly with Steam games). The only problem was that the laptop motherboard did not came with the screw (shame on ASUS). Plenty fast. Priced right. 5 starts.
