Product details
Overview
MG04SCA40EE from Toshiba is a 4 TB enterprise-class 3.5-inch SAS-3 hard disk drive with dual-port 12.0 Gbit/s interface, 7,200 rpm spindle speed, 128 MiB buffer, and Persistent Write Cache with Power Loss Protection for data integrity during unexpected power loss in 24×7 server storage systems.
For engineers reviewing the MG04SCA40EE datasheet, MG04SCA40EE pinout, MG04SCA40EE application, or MG04SCA40EE equivalent, key selection criteria include workload rating (550 TB/year), 512e sector format support, SAS-3 dual-port reliability, and RoHS-compliant 26.1 mm height form factor for dense rack-mount storage deployments.
Technical Context
This drive implements SAS-3.0 protocol with backward compatibility to 6.0/3.0/1.5 Gbit/s, supports 512-byte logical sectors with 520/528-byte protection modes (512e), and uses Toshiba's Persistent Write Cache with capacitor-backed flash to retain uncommitted write data during sudden power loss.
It is rated for continuous 24×7 operation with 1,400,000-hour MTTF, 10⁻¹⁶ non-recoverable error rate, and operates within 5–55°C ambient temperature at altitudes up to 3,048 m - meeting Tier 2 business-critical server and capacity-optimized data center requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar enterprise SAS HDD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Seagate EXOS 7E2000 (ST4000NM0035) | 4 TB, 7,200 rpm, SAS-3, 128 MiB cache, but uses 4Kn native format (no 512e emulation) | Requires OS/driver support for 4K-native addressing; not drop-in compatible with legacy 512-byte stacks | Select when deploying new infrastructure with full 4Kn stack support and no legacy dependency |
| HGST Ultrastar HS1100 (HUS726040AL5210) | 4 TB, 7,200 rpm, SAS-3, 256 MiB cache, same 512e format and dual-port design, but rated for 550 TB/y and 2M-hour MTTF | Higher MTTF and larger cache improve long-term reliability and burst I/O handling in high-concurrency environments | Select when extended lifecycle assurance and higher cache bandwidth are required for mission-critical tier-1 storage |
Compared with Seagate EXOS 7E2000 and HGST Ultrastar HS1100, MG04SCA40EE provides identical 512e compatibility and dual-port SAS-3 functionality at a balanced point of capacity, power (11.8 W max), and certified workload rating - making it optimal for mixed-use midline servers where legacy stack compatibility is mandatory.

FAQ
What is the sector format supported by MG04SCA40EE?
MG04SCA40EE supports 512-byte logical sectors with 520/528-byte protection modes (512e emulation) over native 4,096-byte physical media. This maintains compatibility with legacy operating systems and storage stacks that expect 512-byte sectors while leveraging the efficiency and ECC advantages of advanced format geometry. The drive does not support native 4K (4Kn) addressing mode.
Does MG04SCA40EE include power-loss protection?
Yes, MG04SCA40EE implements Toshiba's Persistent Write Cache with Power Loss Protection (PLP), using onboard capacitors and flash memory to retain uncommitted write data during sudden power interruption. This ensures data integrity without requiring external UPS or RAID controller caching - a critical feature for enterprise servers where power events cannot be fully controlled.
What is the maximum annual workload rating for MG04SCA40EE?
The MG04SCA40EE is rated for 550 TB of total data transferred per year. This workload rating reflects its design for nearline enterprise use - higher than desktop or NAS drives but lower than top-tier mission-critical models. Exceeding this rating may impact warranty coverage and long-term reliability metrics such as MTTF.
Is MG04SCA40EE compatible with SAS-2 or SAS-1 host controllers?
Yes, MG04SCA40EE supports backward compatibility with SAS-2 (6.0 Gbit/s) and SAS-1 (3.0 Gbit/s) host controllers via automatic negotiation. It will operate at the highest mutually supported link speed, ensuring integration into legacy infrastructure without firmware or hardware upgrades - though full 12.0 Gbit/s bandwidth requires a SAS-3 controller.
What environmental conditions is MG04SCA40EE rated for?
MG04SCA40EE is rated for continuous 24×7 operation at ambient temperatures from 5 °C to 55 °C and relative humidity of 5–90% (non-condensing). It withstands operating shock up to 70 G (2 ms) and vibration of 0.75 G (5–300 Hz), making it suitable for rack-mounted enterprise servers and storage enclosures in controlled data center environments.
