Product details
Overview
HDEPV11GEA51F from Toshiba Electronic Devices & Storage Corporation is a 3.5-inch enterprise-capacity hard disk drive with 6 TB formatted capacity, 7,200 rpm spindle speed, and SATA 6.0 Gbit/s interface. It implements 512e Advanced Format sector emulation (host 512B / physical 4,096B), features 256 MiB buffer, and delivers 230 MiB/s sustained transfer rate for nearline business-critical storage systems.
For engineers reviewing the HDEPV11GEA51F datasheet, HDEPV11GEA51F pinout, HDEPV11GEA51F application, or HDEPV11GEA51F equivalent, key selection considerations include its 550 TB/year workload rating, Toshiba Persistent Write Cache with power-loss protection, MTTF of 2.5 million hours, and compatibility with legacy 512-byte-sector host environments.
Technical Context
The HDEPV11GEA51F operates as a SATA-3.3-compliant nearline HDD targeting high-capacity, moderate-IOPS workloads. It uses 512e sector emulation to maintain backward compatibility while enabling higher areal density via 4K physical sectors - supporting read-modify-write operations and host-level alignment transparency.
Power delivery requires dual-rail input: 12 V ±10% and 5 V +10%/−7%, with typical active idle consumption of 5.6 W and random 4KB Q1 read/write at 8.3 W. Acoustic output is 34 dB (sound power) in idle mode per ISO 7779.

Applications
| Cloud-Scale Object Storage | Tier-2 Backup Target |
|---|---|
Use Scenario: Distributed object stores (e.g., Ceph, Scality) requiring cost-effective, high-density, sequential-heavy storage for immutable blobs. IC Role / Device Role / Timing Role: Primary capacity device handling large-block sequential writes and metadata-light reads. Use Value: 6 TB density and 550 TB/year workload rating enable >3-year service life per drive in multi-petabyte deployments. | Use Scenario: Disk-based backup targets for enterprise VM backups, where restore latency is secondary to retention duration and integrity. IC Role / Device Role / Timing Role: Sequential write-optimized storage tier receiving nightly full/incremental image dumps. Use Value: 230 MiB/s sustained transfer and PWC ensure reliable ingestion of multi-terabyte backup streams without write-cache disable penalties. |
| Data Archive Repository | Virtual Desktop Infrastructure (VDI) Warm Tier |
Use Scenario: Long-term WORM-compliant archives for compliance (HIPAA, GDPR), accessed infrequently but requiring bit-rot resilience. IC Role / Device Role / Timing Role: High-integrity, low-power idle storage with periodic integrity scans and SIE-enabled decommissioning. Use Value: 2.5M-hour MTTF and 5.6 W active idle power support >10-year archival duty cycles with minimal operational overhead. | Use Scenario: Non-persistent desktop pools where base images are streamed and user profiles stored separately. IC Role / Device Role / Timing Role: Boot-from-SAN alternative for mid-scale VDI clusters needing local boot volume redundancy. Use Value: SATA 6 Gbit/s interface and 7,200 rpm spindle reduce first-boot latency vs. lower-RPM nearline drives, improving user login consistency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar enterprise nearline HDD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| WD Ultrastar DC HC550 HUS726060ALE610 | 6 TB, 7,200 rpm, 256 MiB buffer, SATA 6 Gbit/s, 512e, 2.5M-hour MTTF - identical workload rating (550 TB/yr) | Includes TCG Opal 2.0 encryption; lacks SIE; uses different vibration compensation algorithm | Preferred when FIPS 140-2 full-disk encryption is required; verify host BIOS/firmware support for Opal provisioning |
| Seagate Exos 7E2000 ST6000NM0034 | 6 TB, 7,200 rpm, 256 MiB buffer, SATA 6 Gbit/s, 512e, 2.0M-hour MTTF - lower workload rating (550 TB/yr same, but shorter warranty period) | Offers optional PowerBalance™ for dynamic power capping; no PWC with PLP - relies on host-initiated flushes | Selected where granular power budgeting is critical; requires host stack validation for write-cache flush behavior |
Compared with WD Ultrastar DC HC550 and Seagate Exos 7E2000, the HDEPV11GEA51F provides unique Sanitize Instant Erase capability and Toshiba's implementation of Persistent Write Cache with PLP - both critical for secure, high-integrity nearline deployments where data remanence and power-failure resilience are non-negotiable.

FAQ
What sector format does the HDEPV11GEA51F use?
The HDEPV11GEA51F implements 512e (512-byte emulation) Advanced Format, presenting 512-byte logical sectors to the host while using 4,096-byte physical sectors internally. This maintains compatibility with legacy operating systems and applications that assume 512-byte sectors, without requiring partition alignment changes.
Does the HDEPV11GEA51F support power-loss protection?
Yes, the HDEPV11GEA51F incorporates Toshiba Persistent Write Cache (PWC) with power-loss protection (PLP). During unexpected power loss, uncommitted write data held in DRAM is transferred to onboard flash memory using capacitor-backed power, ensuring LBA-consistent writes upon recovery.
What is the workload rating for the HDEPV11GEA51F?
The HDEPV11GEA51F is rated for 550 TB per year of total data written, read, or verified - a workload specification validated for continuous 24×7 operation in nearline enterprise environments such as cloud storage and backup targets.
Is Sanitize Instant Erase (SIE) available on the HDEPV11GEA51F?
Yes, the HDEPV11GEA51F supports Sanitize Instant Erase (SIE), a hardware-based data sanitization feature that cryptographically invalidates all user data and metadata in seconds - meeting NIST SP 800-88 Rev. 1 "Purge" requirements for secure decommissioning.
What are the operating temperature limits for the HDEPV11GEA51F?
The HDEPV11GEA51F operates reliably between 5 °C and 55 °C ambient temperature. Its non-operating range extends from −40 °C to +70 °C, supporting safe transport and storage in varied environmental conditions without condensation risk.
