Computex 2014 – Western Digital unveils 4TB SATA Express hybrid drive

Although SATA Express standard is already implemented in Intel’s Z97 chipset and available on the market in most high-end motherboards, the drives compatible with this standard are not available yet. The SATA Express standard can deliver up to 1GB/s by using 2x PCI-Express 2.0 lanes, in comparison to just 600MB/s possible with SATA 3.

Western Digital was the first manufacturer to show a working sample of a 4TB hybrid drive at various booths of motherboard vendors. The drive itself consists of a 4TB mechanical HDD and a 128GB SSD storage, but in Windows the user will see them as two separate drives and can choose which data goes where.
