Both families have four capacity points currently - 32GB, 64GB, 128GB, and 256GB. The 32GB and 64GB EVO Plus cards have a U1 rating. The Class 10 Speed Class / U3 rating guarantees a minimum sequential write speed of 30 MBps. The PRO Plus family, as well as the EVO Plus 128GB and higher capacities are UHS-I rated with a U3 (UHS Speed Class) rating. This week's launch of the PRO Plus and EVO Plus lineup marks Samsung's re-entry into the full-sized SDXC card market. Samsung has launched the standard, PRO, and EVO line of SD cards back in 2014. SD's popularity and affordability has meant that almost all consumer cameras come with a SD card slot. Currently, the standard and micro sizes are more popular in the market. The cards also come in various sizes - standard, mini, and micro. Its popularity spawned two follow-ups retaining the same form-factor - starting with SDSC in 1999 for capacities between 1MB and 2GB, we got SD High Capacity (SDHC) in 2006 (up to 32GB) and SD eXtended Capacity (SDXC) in 2009 (up to 2TB). Its miniature form-factor enabled it to gain traction even in areas dominated by CompactFlash. SD (Secure Digital) cards were introduced in 1999, as a follow-up to the existing MultiMediaCards (MMCs). This review takes the cards out for a spin and attempts to analyze their value proposition. Samsung sampled the 128GB capacity cards in both families ahead of the retail launch. Both families are UHS-I cards, with the PRO Plus aimed at professionals, and the EVO Plus at creators. Two new product families are being announced - the PRO Plus, and the EVO Plus. This week, they are aiming to get back into the SDXC cards market for creators and professionals in the content capture market segment. Since then, the company slowly phased out the full-sized cards from their lineup, and started to focus on microSDXC cards. Samsung had last revamped their SDXC cards lineup back in 2014 to delineate them into the standard, PRO, and EVO categories.
