Product overview

The Dell 4W8JG is a high-capacity enterprise hard drive assembly featuring 16TB SAS 12Gbps interface, 7200 RPM spindle speed, and 3.5-inch form factor with integrated tray for hot-plug installation in Dell storage systems. Built around the Seagate ST16000NM007J Exos X16 drive, it supports mission-critical nearline workloads including cloud storage, big data analytics, and archival with sustained transfer rates over 250MB/s, 256MB cache, and advanced error correction (1 in 10^15 BER). Power efficiency at ~9W active suits dense 24x7 environments, reducing TCO in PowerVault ME5 Series, MD24xx enclosures, and compatible PowerEdge servers. Helium-sealed design enables 7+ platters for superior areal density, MTBF of 2.5 million hours, and workload rating up to 550TB/year. Ideal for RAID arrays demanding high reliability, scalability, and seamless integration in hybrid/multi-cloud infrastructures.

Frequently asked questions

What are the key specifications of the Dell 4W8JG hard drive?

Dell 4W8JG features 16TB capacity, SAS 12Gbps interface, 7200 RPM speed, 3.5-inch LFF form factor with tray, and Seagate ST16000NM007J OEM drive. Includes 256MB cache, ~250MB/s sustained transfer, 4.16ms latency, and 2.5M hours MTBF for reliable nearline performance in Dell storage systems.

Which Dell systems support the 4W8JG drive?

Validated for PowerVault ME5 Series (ME5024 etc.) and MD24xx Series (MD2412/MD2460) enclosures with 3.5-inch hot-plug bays. Compatible with PowerEdge servers accepting 3.5in SAS drives; check Dell support matrices for full list including R-series and C-series models.

What performance benefits does the 4W8JG provide?

Delivers high-capacity nearline performance with 7200 RPM, SAS 12Gbps (backwards compatible to 6Gbps), 256MB DRAM cache, and sustained rates >250MB/s. Helium technology reduces power to ~9W active/5-6W idle, enabling denser deployments vs. air-filled drives.

Is the 4W8JG suitable for 24x7 mission-critical use?

Yes, rated for 550TB/year workload, 2.5M MTBF, 0.35% AFR, 600K load/unload cycles, and 24x7 availability. Advanced format (512e/4Kn options via OEM), ISE/SED support, and 1 in 10^15 error rate ensure reliability in enterprise RAID and cloud environments.

What is the form factor and installation type?

3.5-inch LFF with Dell-specific tray for hot-swap installation. Z-height 26.1mm, dimensions 101.6x147mm, weight ~650g. Plugs directly into compatible PowerVault/MD bays without tools.

How does 4W8JG compare to SATA alternatives?

SAS 12Gbps offers dual-port redundancy, higher queuing, and zoning vs. SATA 6Gbps. Better for shared storage arrays like PowerVault; provides 2x bandwidth potential for demanding IOPS in multi-initiator SAN setups.
