Specifically designed for builders who prefer to mount their hard drive or SSD with screws for maximum stability. The entire converter is made of robust stainless-steel that is perfect for the most demanding applications. SSDs are becoming more common in the average household, but most computer cases still don't have support for 2.5" drives. Since these chassis don't normally have built-in 2.5" SSD/HDD bays, a 2.5" to 3.5" HDD/SSD converter is an absolute necessity when purchasing 2.5" HDDs/SSDs. For enterprise, it's valuable for upgrading 3.5" HDD file servers to 2.5" HDD/SSD file servers without paying a tremendous amount for an entire system upgrade.
