Product details
Overview
MG08ADA800A from Toshiba Electronic Devices & Storage Corporation is an enterprise-class 3.5-inch SATA hard disk drive with 8 TB formatted capacity, 7200 rpm spindle speed, 256 MiB buffer, 4Kn logical sector format, and SATA-3.3 interface supporting 6.0 Gbit/s data transfer - deployed in tier-2 business-critical storage servers requiring high-capacity, nearline reliability.
For engineers reviewing the MG08ADA800A datasheet, MG08ADA800A pinout, MG08ADA800A application, or MG08ADA800A equivalent, this page delivers verified mechanical, electrical, interface, reliability, and command-set specifications - including SATA power pin mapping, 550 TB/year workload rating, Sanitize Instant Erase (SIE) option availability, and compatibility with legacy 4Kn host environments.
Technical Context
The MG08ADA800A implements a SATA-3.3 interface compliant with ANSI INCITS 397-2005 and SATA Revision 3.3 standards, supporting negotiated link speeds of 1.5/3.0/6.0 Gbit/s. It uses a dual-voltage power architecture (12 V ±10 % / 5 V +10%/-7%) with staggered spin-up control via the SPIN pin and optional POWER DISABLE functionality on P3.
This drive operates at 7200 rpm with a maximum sustained data transfer rate of 248 MiB/s (4Kn), employs perpendicular magnetic recording (PMR), and supports full-disk encryption via optional Sanitize Instant Erase (SIE) - all within a 26.1 mm height, 3.5-inch form factor meeting enterprise environmental limits (5–55 °C operating temperature, 2,000,000-hour MTTF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Formatted Capacity | 8 TB - usable host-addressable space using decimal definition (1012 bytes), aligned to enterprise storage provisioning requirements. |
| Interface | SATA-3.3 - backward-compatible with SATA-3.0/2.0/1.0 hosts; enables 6.0 Gbit/s burst transfers and native command queuing (NCQ). |
| Rotation Speed | 7200 rpm - balances latency, throughput, and power efficiency for nearline workloads versus archival drives. |
| Buffer Size | 256 MiB - improves sequential/random I/O performance by absorbing write bursts and enabling read-ahead caching. |
| Logical Block Length | 4096-byte (4Kn) - eliminates read-modify-write overhead for modern OSes and hypervisors supporting Advanced Format natively. |
| Rated Annual Workload | 550 TB/year - defines maximum annual data throughput under enterprise duty cycle, informing RAID rebuild time and longevity planning. |
| MTTF / AFR | 2,000,000 hours / 0.44 % - quantifies long-term field reliability for 24/7 operation in midline server deployments. |
| Power Consumption (Active) | 9.29 W (Write/Read 4KB Q1) - informs thermal design, PSU sizing, and data center PUE calculations for dense rack configurations. |
Pinout & Package
Package: 3.5-inch form factor, 26.1 mm height, 101.85 mm width × 147.0 mm length, max weight 720 g - industry-standard mechanical footprint compatible with OEM server trays and hot-swap carriers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| S1, S4, S7, P4–P6, P10, P12 | GND | Signal and power return paths; multiple ground pins ensure low-impedance reference and EMI suppression across SATA differential pairs. |
| S2, S3 | A+/A− | Device receive differential pair (Rx); connects to host transmitter for SATA command/data ingress. |
| S5, S6 | B−/B+ | Device transmit differential pair (Tx); carries responses, status, and data to host controller. |
| P3 | PWDIS | Power Disable input - asserted low to inhibit spin-up; used for coordinated power sequencing in multi-drive backplanes. |
| P7–P9 | V5 | +5 V power supply - pre-charged and main rails deliver stable voltage for logic, servo, and preamp circuits. |
| P13–P15 | V12 | +12 V power supply - supplies motor driver and actuator coil; staggered ramp-up reduces inrush current. |
| P11 | Spin / ACT | Open-drain output - indicates drive activity (ACT) and reports staggered spin-up mode detection (Spin) to host BMC. |
Key Features
| Feature | Design Value |
|---|---|
| Sanitize Instant Erase (SIE) Option | Enables cryptographic erasure of all user data in seconds without physical destruction - meets NIST SP 800-88 Rev. 1 Clear requirements for secure decommissioning. |
| 4Kn Logical Sector Format | Eliminates 512e translation layer overhead, improving random write performance and reducing firmware complexity in Linux KVM and VMware ESXi environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar enterprise HDD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Seagate Exos X16 ST16000NM001G | 16 TB capacity, SAS-3 interface, 256 MiB buffer, 7200 rpm, 550 TB/year rating - higher density but requires SAS infrastructure. | Deployed where dual-port redundancy, higher queue depth, or SAS expander scalability is mandatory - not drop-in SATA replacement. | Select when migrating from SATA to SAS-based scale-out storage or requiring dual-port failover capability. |
| Western Digital Ultrastar DC HC550 HUS728T8TALE6L4 | 8 TB capacity, SATA-3.3 interface, 256 MiB buffer, 7200 rpm, 550 TB/year rating, 4Kn format - identical mechanical and electrical specs except for firmware feature set. | Same use cases as MG08ADA800A; differs in SMART attribute reporting, power management behavior, and SIE implementation timing. | Choose based on qualification status with specific server OEMs (e.g., Dell PowerEdge vs. HPE ProLiant) and firmware update cadence requirements. |
Compared with Seagate Exos X16 and WD Ultrastar DC HC550, the MG08ADA800A offers identical 8 TB/7200 rpm/4Kn/SATA-3.3 enterprise specifications but provides Toshiba-specific SIE certification and RoHS compliance documentation aligned to Japanese export controls - making it preferred for APAC-region data center refresh programs.

FAQ
What is the logical sector format supported by MG08ADA800A?
The MG08ADA800A uses a 4096-byte (4Kn) logical sector format - meaning the drive presents native 4 KiB sectors to the host without emulation. This eliminates read-modify-write penalties and aligns with modern OS filesystems like XFS, ZFS, and NTFS when formatted with 4 KiB cluster sizes. The MG08ADA800A does not support 512e or 512n modes.
Does MG08ADA800A support hardware-based encryption?
The base MG08ADA800A model does not include Self-Encrypting Drive (SED) functionality. However, Toshiba offers the MG08ADP800A variant with SED and the MG08ADA800AY variant with Sanitize Instant Erase (SIE). SIE provides cryptographic erase capability but does not perform real-time encryption of host data - only secure deletion upon command.
What is the maximum sustained data transfer rate of MG08ADA800A?
The MG08ADA800A achieves a maximum sustained data transfer rate of 248 MiB/s under 4Kn workload conditions, as measured in Toshiba's internal testing using sequential read patterns. This value reflects real-world throughput achievable over SATA-3.3 at 6.0 Gbit/s, accounting for protocol overhead and drive firmware processing latency.
Can MG08ADA800A be used in RAID 5 or RAID 6 arrays?
Yes, MG08ADA800A is qualified for use in RAID 5 and RAID 6 configurations in enterprise servers and storage appliances. Its 2,000,000-hour MTTF, error recovery controls, and 550 TB/year workload rating make it suitable for parity-based RAID deployments where rebuild time and URE tolerance are critical - provided the RAID controller supports TLER or equivalent error handling.
What power supply requirements must be met for MG08ADA800A?
MG08ADA800A requires both +12 V (±10 %) and +5 V (+10 % / −7 %) supplies delivered through the standard 15-pin SATA power connector. The drive draws up to 9.29 W during active 4 KB random I/O and 5.61 W in Active Idle (Idle-A) mode. Note that 3.3 V is not used - the P1 and P2 pins are unused and must remain unconnected.
Is MG08ADA800A compatible with legacy BIOS or UEFI systems?
Yes, MG08ADA800A is fully compatible with both legacy BIOS and UEFI firmware interfaces. It responds to standard ATA IDENTIFY DEVICE (ECh) and ATA IDENTIFY PACKET DEVICE commands, and supports bootable partitioning via MBR or GPT. No special drivers or firmware patches are required for system boot or OS installation on x86-64 platforms.
