Mixing Hard Disk Drives of 512 Byte native and 512 Byte emulated Block Size in RAID Systems
Mixing Hard Disk Drives of 512 Byte native and 512 Byte emulated Block Size in RAID Systems (1.4MB)
Hard Disk Drives (HDDs) for NAS and Enterprise Storage come in two different flavors of block size. Traditionally, the internal block size of HDDs is 512 byte, with 512 byte also used at the external interface. This technology is called 512 byte native, or 512n. Newer HDD models use an internal block size of 4k byte for higher storage efficiency, but still provide 512 byte at the external interface through a transparent emulation process. This technology is called 512 byte emulated (512e). Additionally drives with the 4k byte internal block format at the interface (4k byte native) are available, but these are rare and exclusively used in specific enterprise applications.

High-Reliability FC-MAMR Nearline HDD with a Capacity of 18 TB (829KB)
As demand for nearline HDDs for data centers is growing, the requirements for data storage solutions for both cyber and physical spaces are diversifying, making it necessary to develop new innovative technologies for not only reading but also writing data. High-reliability technologies are attracting plenty of attention as a means to overcome the limit to the HDD recording density and thereby solve the information explosion problem.
