The MD04ACA400 is a hard disk drive model manufactured by Toshiba, a global provider of storage solutions. This model is part of the Toshiba’s Enterprise Capacity series and is designed for use in mission-critical applications, such as data centers, cloud storage systems, and high-performance computing.
The MD04ACA400 features a 3.5-inch form factor and has a storage capacity of 4 terabytes (TB). It uses a SATA III interface and has a 128MB cache buffer, which helps to improve read and write performance. The drive operates at a rotational speed of 7200 revolutions per minute (RPM) and has a data transfer rate of up to 6 Gb/s.
One of the key features of the MD04ACA400 is its persistent write cache technology, which helps to maintain the integrity of data during power loss events. This technology also helps to improve write performance by enabling the drive to temporarily store data in cache memory before writing it to the platters.
In terms of reliability, the MD04ACA400 is built with features like ramp loading technology, which protects the drive’s heads and platters during transportation and handling, and a 2.5 million hour mean time between failures (MTBF) rating, which is a measure of the drive’s expected lifespan. Additionally, the drive is designed to operate 24/7 and has an annualized workload rating of up to 550 TB per year.
Overall, the Toshiba MD04ACA400 is a high-capacity hard drive designed for use in mission-critical applications. Its persistent write cache technology, high storage capacity, and 7200 RPM rotational speed make it a good choice for data-intensive workloads that require fast and reliable performance.

More about our HDDs & SSDs
Our Hard Drives are sanitized and tested to the NIST 800-88 Rev. 1 standard before sale.
During this process, our drives are Tested for errors and Graded for performance and remaining life. All drives we sell are Grade A unless otherwise stated.
When you receive your hard drive, the drive will be in a RAW or factory new state and will need to be formatted by your system before use.
Device Grading:
During the erasure process, our drivers are tested for errors and graded based on performance, device SMART data, and overall usage.
Grade A:
- Overall drive health is above 80%
- No reallocated or pending sectors
- Power-on hours are under 50k hours
We do not offer Grade B drives.
