Fits 2 x 2.5"" SATA SDD/ HDD(up to 9.5mm drive thickness). Full metal design. Every year technology is able to become more and more advanced and is constantly improving. Also with being physically the smallest and performing the best is the end goal of any storage system. This is why SFF (Small Form Factor) storage systems are becoming more popular due to its low power consumption and space-saving benefits. With the advent of recent solid state technology this allows 2.5" SSD's to easily achieve high transfer rate which overcomes the 3.5" SATA hard drives in every category except capacity. Therefore maximizing the capacity in a limited space becomes the most important task that many storage consulting firms are often faced with. For SFF systems we introduce the Icy Dock MB992SK-B 2.5" SATA Mobile Rack solution for use in 3.5" device bays (Floppy bay).
