The Dell 20TB 12Gbps SAS 7,200 RPM 3.5-inch Enterprise Hard Drive (Part Numbers: 3DJ233-150 / 0R3G03 / R3G03; Seagate Model: ST20000NM004D) is a high-capacity, enterprise-grade storage drive built on Seagate’s flagship Exos X20 platform. Engineered for 24/7 hyper-scale applications, cloud data centers, and massive enterprise storage arrays, this drive provides ultra-dense storage capacity with high transfer rates via a high-speed 12Gb/s SAS interface.
Featuring a helium-sealed drive design with Conventional Magnetic Recording (CMR) technology, this 20TB hard drive operates at 7,200 RPM with a generous 256MB cache buffer to deliver sustained data transfer rates up to 285 MB/s. The helium environment drastically reduces aerodynamic drag on internal pladders, lowering total power consumption, minimizing operational vibration, and reducing operational thermal output in dense 3.5-inch server backplanes.
Available from DataDive, your trusted Technology Hardware Supplier in Qatar, this genuine Dell 20TB SAS enterprise HDD is available in our Storage collection, ideal for server storage upgrades, NAS/SAN array expansions, cold storage repositories, and bulk cloud storage infrastructure across Dell PowerEdge servers and PowerVault storage systems.
