Scalable, responsive, and innovative, the Exos X18 is designed for maximum storage capacity and the highest rack-space efficiency, tuned for large data transfers and low latency. The ST16000NM000J steps up from the X16 with 16TB capacity and enhanced caching for improved performance across mixed workloads — and like its predecessor, it connects via standard SATA 6Gb/s, requiring no SAS HBA or specialist hardware.

Helium Sealed Design With Environmental Monitoring

The helium sealed-drive design delivers lower total cost of ownership through lower power and weight, with digital environmental sensors to monitor internal drive conditions for optimal operation and performance. Helium’s lower density reduces platter drag, enabling more platters per drive and lower operating temperatures — essential engineering at 16TB capacity in a standard 3.5″ form factor.

CMR & Enterprise Performance

The Exos X18 uses CMR to deliver consistent and predictable performance across a wide range of workloads, with up to 270 MB/s sustained transfer rate and impressive random read/write performance of 170/550 IOPS. Combined with hot-plug support and PowerBalance power/performance technology, it is drop-in ready for enterprise RAID and NAS environments.

Broad Enterprise Compatibility

The Exos X18 is compatible with popular distributed file systems including Hadoop and Ceph, and with network-attached storage systems including Synology and QNAP. FastFormat technology allows field-switching between 512e and 4Kn sector formats to accommodate both legacy and modern storage platforms without replacing the drive.
