18TB NAS hard drive

The MaxDigitalData MDD18TSATA25672NAS is an 18TB 3.5-inch internal hard drive built for network-attached storage enclosures. It runs at 7200 RPM with a 256MB cache and connects through a SATA 6.0Gb/s interface. The drive is designed for continuous operation in RAID arrays, surveillance systems and desktop NAS units.

Home labs and small-business NAS

This drive suits administrators who need high-capacity, 7200 RPM storage for file sharing, backup or CCTV recording in a multi-bay NAS. It is not intended for portable external use, laptop upgrades or systems that only accept 2.5-inch drives. Buyers requiring a different physical size or a non-SATA interface should look elsewhere.

SATA 6.0Gb/s interface

The single specification that determines compatibility is the SATA 6.0Gb/s connection; the host system must provide a standard SATA data and power port. The 3.5-inch form factor measures 147.00mm long, 101.85mm wide and 26.10mm high, so the chassis bay must accommodate those dimensions. No other interface or form factor is supported.
