EXPERT FEATURES
- 4TB NAS-Ready Storage : Add 4TB of dedicated storage to a compatible NAS for shared files, photos, media libraries, and backups. This is a bare internal drive, not a complete NAS or USB external drive.
- 24/7 Storage Design : Engineered for always-on Synology storage systems and multi-user workloads, with extensive manufacturer compatibility and stress validation.
- 100% CMR Recording : Conventional Magnetic Recording (CMR) supports consistent sustained write behavior, including NAS and RAID workloads.
- SATA 6Gb/s Interface : Uses a standard internal SATA 6Gb/s data connection in a 3.5-inch drive bay. The host must provide compatible SATA data and power connections.
- 5400 RPM / 256MB Cache : Combines 5400 RPM rotational speed with 256MB cache, tuned for NAS storage duties rather than NVMe SSD-like performance.
- Up to 202MB/s Sustained Transfer : Synology specifies a typical maximum sustained data transfer speed of 202MB/s; actual results depend on workload, enclosure, RAID mode, and network.
- 180TB/Year Workload Rating : Rated for up to 180TB per year of host data reads, writes, and verification commands in supported operating conditions.
- 1 Million-Hour MTBF : Manufacturer-rated mean time between failures of 1,000,000 hours is a statistical fleet measure, not a predicted lifetime of an individual drive.
- DSM Firmware Integration : Firmware can be updated through Synology DiskStation Manager on supported Synology NAS models, avoiding drive removal for eligible updates.
- Efficient Typical Power Draw : Rated at 3.96W active idle and 4.85W during a random 4KB read/write workload, with consumption varying by system.
