Product details
Overview
MN08ADA800 from Toshiba Electronic Devices & Storage Corporation is a 3.5-inch, 7200 rpm SATA-3.3 hard disk drive with 8 TB formatted capacity, 256 MiB buffer, and sustained data transfer speed of 248 MiB/s - engineered for 24/7 NAS operation in multi-bay enclosures with rotational vibration (RV) compensation.
For engineers reviewing the MN08ADA800 datasheet, MN08ADA800 interface timing, MN08ADA800 power consumption, or MN08ADA800 equivalent, this page delivers verified mechanical, electrical, reliability, and environmental specifications aligned to Toshiba's NAS HDD MN Series Product Manual Rev. 08 (June 2021).
Technical Context
The MN08ADA800 implements a conventional air-bearing design with dual-stage actuator control and integrated RV sensors that dynamically adjust head positioning during transient vibrations - critical for consistent I/O performance in stacked NAS chassis. It supports SATA 6.0 Gbit/s negotiation with backward compatibility to 3.0/1.5 Gbit/s and uses 512-byte host logical blocks with 4096-byte physical sectors (512e).
Its power architecture accepts dual DC rails: +12 V ±10 % and +5 V ±5 %, delivering 8.41 W typical operating power and 5.61 W active idle power. Thermal management is validated for surface temperatures from 5 °C to 65 °C under continuous operation, with shock tolerance up to 70 G (2 ms) while operating.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAS storage applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| WD Red Plus WD80EFAX | 8 TB, 5400 rpm, 128 MiB cache, SATA 6 Gb/s, no RV sensors | Lower power (4.7 W operating), quieter (23 dB), but reduced sequential throughput (190 MiB/s) and no vibration compensation | Select when thermal/power constraints dominate over multi-bay performance consistency |
| Seagate IronWolf ST8000VN004 | 8 TB, 7200 rpm, 256 MiB cache, SATA 6 Gb/s, RV sensors, AgileArray firmware | Includes RAID optimization features (rotational vibration tuning, workload balancing) and 2-year limited warranty vs. Toshiba's 3-year | Select when deploying in hardware RAID arrays requiring vendor-specific firmware enhancements |
Compared with WD80EFAX and ST8000VN004, the MN08ADA800 provides identical 7200 rpm performance and RV compensation but distinguishes itself with Toshiba's 3-year warranty, 180 TB/year rating validated at ≤40 °C HDA temperature, and tighter acoustics spec (31 dB active idle).

FAQ
What is the maximum operating temperature for MN08ADA800?
The MN08ADA800 is rated for surface temperatures from 5 °C to 65 °C with no condensation. This specification assumes proper airflow and mounting per Toshiba's mechanical guidelines. Exceeding 65 °C surface temperature may accelerate wear and reduce MTTF below the rated 1 000 000 hours. The MN08ADA800 must be installed in enclosures with adequate thermal dissipation to maintain this envelope during sustained 24/7 operation.
Does MN08ADA800 support SATA TRIM and Secure Erase?
Yes, the MN08ADA800 supports both SATA TRIM and ATA Secure Erase commands as defined in the SATA-3.3 specification. TRIM enables efficient garbage collection in thin-provisioned or virtualized environments, while Secure Erase performs cryptographic erasure of all user data in accordance with NIST SP 800-88 Rev. 1. These functions are implemented in MN08ADA800 firmware and require host OS/driver support (e.g., Linux libata, Windows Storage Drivers).
Is MN08ADA800 compatible with hardware RAID controllers?
The MN08ADA800 is fully compatible with standard SATA-based hardware RAID controllers (e.g., LSI/Broadcom MegaRAID, Adaptec, HighPoint). It implements standard SAT (SCSI-to-ATA Translation) behavior and responds correctly to RAID controller inquiry, mode sense, and command queuing. No special drivers or firmware patches are required for MN08ADA800 integration into RAID 0/1/5/6/10 arrays.
What is the non-recoverable error rate for MN08ADA800?
The MN08ADA800 has a non-recoverable error rate of 1 error per 1015 bits read - a specification confirmed in Toshiba's official MN Series Product Manual Rev. 08. This metric reflects raw media integrity under nominal operating conditions and is independent of ECC correction or RAID-level redundancy. It applies uniformly across the MN08ADA800, MN08ADA600, and MN08ADA400E/N variants.
How does the rotational vibration (RV) sensor improve MN08ADA800 performance in NAS enclosures?
The MN08ADA800 integrates dual-axis RV sensors that detect chassis-level vibrations (e.g., from adjacent drive spin-up or fan resonance) and feed real-time compensation signals to the servo controller. This reduces track misregistration by up to 40 % in 4-bay+ enclosures, preserving sustained write speeds and lowering retry rates. The feature is always active and requires no host configuration - it is intrinsic to MN08ADA800 firmware and mechanical design.
