Description

Description

Western Digital offers an 8TB 3.5-inch SATA internal hard drive, designed for high reliability applications such as NAS, servers, RAID arrays, surveillance systems, and archival workloads.

  • Spindle speed: 7200 RPM
  • Interface: SATA 6 Gb/s
  • Cache: 256MB
  • Recording technology: CMR
  • Construction: HelioSeal for better cooling and quiet operation
  • Optimization: for 24/7 use with NASware firmware
  • Vibration protection: multi-axis shock protection and rotational vibration tolerance
  • Workload rating: 550 TB/year
  • Sustained transfer speeds: up to 255 MB/s
  • MTBF: 2.5 million hours
  • Dimensions: 26.1 x 101.6 x 147 mm
  • Weight: approximately 720 g

The hard drive is internal and is not an SSD or an external drive.

Top Capacity 8TB & Speed 7200 RPM

The internal hard drive from Western Digital 8TB offers massive storage space for critical data. With a rotation speed of 7200 RPM and continuous data transfer up to 255 MB/s, it ensures fast access and high performance in server environments and large archival workloads.

HelioSeal Technology & CMR Recording

Using HelioSeal technology (helium sealing), the drive achieves lower operating temperatures and quieter operation. The CMR (Conventional Magnetic Recording) recording method guarantees consistent write performance and maximum reliability, making it ideal for RAID arrays where stability is paramount.

Optimization for 24/7 Use with NASware

The drive is designed for continuous 24/7 operation. The specialized NASware firmware improves compatibility with NAS and RAID systems, while the multi-axis shock protection and rotational vibration tolerance (RV sensors) ensure data integrity in multi-drive environments.

Business Reliability & Workload

With a workload rating of 550 TB per year and a mean time between failures (MTBF) of 2.5 million hours, this 3.5-inch drive offers the durability required by data centers. The large 256MB cache helps in fast handling of multiple requests, providing a smooth experience even under heavy load.
