18 TB CMR desktop drive
The Toshiba X300 Pro HDWR51JXZSTB is an 18 TB 3.5 inch internal hard drive built for high-end workstations and multimedia systems. It uses CMR recording technology and a SATA 6.0Gb/s interface to deliver consistent throughput for demanding creative and gaming workloads.
18 TB capacity with 300 TB per year workload rating
The drive provides 18 TB of storage space and is rated for workloads up to 300 TB per year with an MTTF of 1.0 million hours. A 7200 RPM spindle speed and 512 MB cache shorten response times for large media files, while the SATA 6.0Gb/s link sets the maximum sustained transfer ceiling.
26.1 mm height fits standard 3.5 inch bays
At 26.10 mm high, 101.85 mm wide and 147.00 mm long, the drive fits standard desktop drive bays and mounting points. The SATA data and power connectors face the rear for straightforward cabling in typical chassis layouts. Retail or OEM packing may vary.

Questions about this item
Will the 18TB SATA 6.0Gb/s interface work with my older motherboard that only has SATA 3Gb/s ports?
The drive is backward compatible with SATA 3Gb/s ports and will operate at the slower 3Gb/s link speed without any configuration changes.
How can I confirm the 7200 RPM spindle speed and 512MB cache are active after installation?
Use a tool such as CrystalDiskInfo or the BIOS drive information page; both will report the rotational speed as 7200 RPM and the cache size as 512 MB.
Does the retail box include a SATA data cable and mounting screws, or must I buy them separately?
The drive is sold as a bare unit; a SATA data cable and 3.5" mounting screws are not included and must be purchased separately.
