Product details
Overview
MG04ACA200E from Toshiba is a 2 TB enterprise-capacity 3.5-inch SATA HDD designed for nearline storage in 24×7 data center environments. It delivers 7,200 rpm rotational speed, 6.0 Gbit/s SATA interface, 128 MiB buffer, 205 MiB/s sustained transfer rate, and supports 550 TB/year workload - deployed in tier-2 business-critical servers and capacity-optimized storage systems.
For engineers reviewing the MG04ACA200E datasheet, MG04ACA200E pinout, MG04ACA200E application, or MG04ACA200E equivalent, key selection criteria include its 512e sector emulation mode, persistent write cache with power-loss protection (PLP), MTTF of 1.4M hours, non-recoverable error rate of 10⁻¹⁶, and RoHS-compliant 26.1 mm height form factor.
Technical Context
This drive implements SATA 3.0 (6.0 Gbit/s) with native command queuing and 512-byte logical sector emulation (512e) over 4096-byte physical sectors. It uses Toshiba's Persistent Write Cache (PWC) with Power Loss Protection to retain uncommitted write data in flash during sudden power loss - a feature confirmed for MG04ACAxxxE models including MG04ACA200E.
Rated for continuous 24×7 operation, it meets 550 TB/year workload limits and operates within 5–55 °C ambient temperature. Its mechanical design conforms to industry-standard 3.5-inch form factor (101.6 mm × 147 mm × 26.1 mm max) with shock resistance up to 70 G operating and 300 G non-operating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Formatted Capacity | 2 TB - actual usable space after low-level format and firmware overhead; reported as ~1.82 TiB by OS using binary units. |
| Interface | SATA 3.0 (6.0 Gbit/s) - backward compatible with 3.0/1.5 Gbit/s; enables full bandwidth utilization in modern server backplanes. |
| Rotation Speed | 7,200 rpm ±0.1% - ensures consistent latency and throughput for mixed random/sequential workloads. |
| Average Latency | 4.17 ms - fixed mechanical delay per revolution; critical for predictable I/O response in virtualized environments. |
| Buffer Size | 128 MiB - DRAM cache used for read-ahead, write coalescing, and NCQ reordering to improve IOPS efficiency. |
| Sustained Transfer Rate | 205 MiB/s - maximum sequential throughput achievable under optimal host conditions and full-disk linear reads. |
| MTTF | 1,400,000 hours - statistical reliability metric for large fleets; supports multi-year deployment in enterprise RAID arrays. |
| Workload Rating | 550 TB/year - annual data volume threshold defining endurance class; exceeds typical nearline HDD requirements. |
Pinout & Package
MG04ACA200E uses a standard 3.5-inch SATA HDD mechanical package: 101.6 mm (W) × 147 mm (L) × 26.1 mm (H) max, weighing ≤770 g. Electrical interface conforms to SATA revision 3.0 specification with 7-pin data connector and 15-pin power connector.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SATA Data Pin 1–7 | Differential TX/RX pairs + ground | Carries serialized 6.0 Gbit/s data; requires controlled-impedance routing and proper common-mode choke filtering. |
| SATA Power Pin 1–15 | +5 V, +12 V, ground, staggered spin-up control | Supports hot-swap sequencing; Pin 3 (PRECHARGE) enables soft-start to limit inrush current on +12 V rail. |
| Ground Pins (multiple) | Signal & power return paths | Minimizes EMI and voltage drop; must be connected with low-inductance paths per SATA compliance. |
Key Features
| Feature | Design Value |
|---|---|
| 512e Advanced Format | Emulates 512-byte logical sectors while using 4096-byte physical sectors - maintains OS/driver compatibility without requiring 4K-aware firmware updates. |
| Persistent Write Cache (PWC) with PLP | Retains cached write data in onboard NAND flash during unexpected power loss - prevents corruption of data reported as "written" but not yet committed to platters. |
| 24×7 Enterprise Operation | Thermal, vibration, and power management tuned for uninterrupted service in rack-mounted storage enclosures with forced-air cooling. |
| RoHS-Compliant Construction | Meets EU Directive 2011/65/EU limits for Pb, Hg, Cd, Cr⁶⁺, PBB, PBDE - verified for homogeneous material composition per Toshiba specification. |
| 7,200 rpm + 128 MiB Buffer | Delivers balanced performance for both transactional and streaming workloads - higher spindle speed than 5,400 rpm nearline drives, larger cache than legacy 64 MiB models. |
Applications
| Enterprise Nearline Storage | Tier-2 Business-Critical Servers |
|---|---|
Use Scenario: Deployed in JBOD or RAID-6 arrays within hyperscale object storage clusters handling cold-to-warm data tiers. IC Role / Device Role / Timing Role: Primary bulk storage device providing high-capacity, cost-effective persistence with predictable latency and error resilience.

IC Role / Device Role / Timing Role: Back-end storage for differencing disks and persona data - optimized for random read-heavy I/O patterns with NCQ support. Use Value: 128 MiB buffer and NCQ reduce average I/O completion time; 1.4M-hour MTTF lowers replacement frequency in large-scale deployments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar enterprise nearline HDD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Seagate ST2000NM0033 | 2 TB, 7,200 rpm, 128 MiB cache, SATA 6 Gb/s, 512e, MTTF 1.2M hrs, no PWC/PLP | Lacks persistent write cache - higher risk of metadata corruption during ungraceful shutdown | Select when cost sensitivity outweighs power-loss data integrity requirements |
| WD Ultrastar DC HC310 HUS726020AL | 2 TB, 7,200 rpm, 256 MiB cache, SATA 6 Gb/s, 512e, MTTF 2.0M hrs, includes PLP | Higher cache and MTTF; same 26.1 mm height but different vibration tolerance specs | Select when extended warranty, higher endurance, or tighter vibration specs are required |
Compared with ST2000NM0033 and WD HUS726020AL, the MG04ACA200E offers Toshiba-specific PWC/PLP implementation validated for enterprise power-loss scenarios, balanced 128 MiB cache size, and strict adherence to 550 TB/y workload limits - making it optimal for mid-line storage where data integrity and predictable lifecycle are prioritized over maximum cache or MTTF.

FAQ
What is the sector format used by MG04ACA200E?
The MG04ACA200E uses 512-byte logical sector emulation (512e) over native 4096-byte physical sectors. This maintains compatibility with legacy operating systems and hypervisors that expect 512-byte addressing, while enabling improved areal density and error correction efficiency. The MG04ACA200E does not support native 4K (4Kn) mode.
Does MG04ACA200E include power-loss protection?
Yes, MG04ACA200E implements Toshiba's Persistent Write Cache (PWC) with Power Loss Protection (PLP). When power fails unexpectedly, backup capacitors supply energy to flush cached write data from DRAM to onboard NAND flash memory, preventing data loss for commands already acknowledged to the host. This feature is confirmed for all MG04ACAxxxE variants.
What is the maximum operating temperature for MG04ACA200E?
The MG04ACA200E is rated for continuous operation between 5 °C and 55 °C ambient temperature. Exceeding 55 °C may trigger thermal throttling or reduce MTTF. The drive includes internal thermal sensors and firmware-controlled spin-down logic to maintain safe junction temperatures under sustained 24×7 workloads.
Is MG04ACA200E compatible with standard 3.5-inch SATA backplanes?
Yes, MG04ACA200E complies fully with SATA 3.0 mechanical and electrical specifications. Its 101.6 mm × 147 mm × 26.1 mm dimensions, 7-pin data connector, and 15-pin power connector match industry-standard 3.5-inch HDD form factors - ensuring plug-and-play integration into server chassis, JBOD enclosures, and NAS platforms supporting SATA III.
What workload rating applies to MG04ACA200E?
The MG04ACA200E is rated for 550 TB/year - meaning it is qualified to reliably handle up to 550 terabytes of total data written annually. This workload rating reflects its enterprise-class durability and distinguishes it from desktop or NAS-class drives with lower annual limits (e.g., 180–300 TB/year).
