What solid-state hard drive form factor has dimensions similar to platter-type magnetic drives?

Solid-state drives (SSDs) are available in a variety of form factors, such as a "stick" resembling a memory module (M.2) or a 2.5′′ metal-encased box. SSDs are also available in 3.5′′ form factors. M.2 and mSATA are SSD form factors. NVMe is a data storage technology that is often used with M.2 drives, while M.2 drives can alternatively use the older Advanced Host Controller Interface standard (AHCI).
