Product overview of the Toshiba MG04ACA300A

The MG04ACA300A Toshiba hard disk drive is a high-performance storage device designed for enterprise-level applications. This hard drive has a capacity of 3 terabytes (TB) and operates at 7,200 revolutions per minute (RPM) with a SATA 6 gigabits per second (Gbps) interface. The hard drive also features a 64 megabyte (MB) buffer and a 3.5-inch form factor. In this article, we will delve into the features of the MG04ACA300A hard drive in detail.


The MG04ACA300A Toshiba hard disk drive has a storage capacity of 3 TB. This is a large storage capacity, suitable for enterprise-level applications such as data centers and cloud storage. With 3 TB of storage capacity, users can store a large amount of data such as documents, images, videos, and other types of files.

Rotational Speed

The rotational speed of a hard disk drive is an essential factor that determines its performance. The MG04ACA300A hard disk drive operates at 7,200 RPM, which is a relatively high speed for a hard disk drive. The high RPM ensures that data can be accessed quickly and transferred at a high rate. This makes the hard disk drive suitable for applications that require high data transfer rates such as server and storage systems.


The interface of a hard disk drive is the means by which it communicates with the computer system. The MG04ACA300A hard disk drive features a SATA 6 Gbps interface, which is a high-speed interface capable of transferring data at a rate of up to 6 gigabits per second. This high-speed interface ensures that data can be transferred quickly and efficiently, reducing waiting times and improving performance.


The buffer, also known as the cache, is a small amount of high-speed memory built into the hard disk drive. The buffer stores data that the hard disk drive is currently reading or writing, allowing for faster access to frequently accessed data. The MG04ACA300A hard disk drive features a 64 MB buffer, which is a relatively large buffer compared to other hard disk drives. This large buffer ensures that frequently accessed data is readily available, improving performance and reducing waiting times.

Form Factor

The form factor of a hard disk drive refers to its physical dimensions and shape. The MG04ACA300A hard disk drive features a 3.5-inch form factor, which is a standard size for enterprise-level hard disk drives. The 3.5-inch form factor makes the hard disk drive compatible with most server and storage systems, making it an ideal choice for enterprise-level applications.


Reliability is a critical factor for enterprise-level hard disk drives. The MG04ACA300A hard disk drive is designed for 24/7 operation and has a mean time between failures (MTBF) of 1.2 million hours. The MTBF is an indication of how long a hard disk drive is likely to operate without failing. A high MTBF ensures that the hard disk drive is reliable and can operate continuously without interruption.

Power Consumption

The power consumption of a hard disk drive is an important factor to consider when selecting a hard disk drive for enterprise-level applications. The MG04ACA300A hard disk drive has a power consumption of 11.3 watts during read/write operations and 6.2 watts during idle periods. The low power consumption of the hard disk drive ensures that it operates efficiently and reduces the overall energy consumption of the system.

Noise Level

The noise level of a hard disk drive is a factor to consider when selecting a hard disk drive for enterprise-level applications.

About New Bulk Pack Products

New Bulk Pack products come with clamshell boxes and do not have any manufacturer warranty. Many times manufacturers disassemble whole units to use parts or pulled from a new system. Typically, this product doesn't come with software or instructions unless indicated and no Manufacturer’s genuine warranty. You can take note these are not brand new products.

When it comes to storing files and processing information, it is difficult to shove the impressive SATA hard drives aside. Although many people tend to regard hard disk drives as old technology, the new highly-performing variants have raised the bar. One of the most impressive variants is hard drives with the SATA interface and transfer speed of up to 6Gbps.

These are among the best drives to buy presently. They come with flash-speed disks that load several times faster than traditional hard drives. Another added advantage is that they come in either 2.5-inch sizes or 3.5-inch sizes. Users can find SATA 6Gbps hard drives that will nicely fit their case or enclosure.

SATA 6Gbps hard drives are designed to offer maximum performance. They connect to servers, PCs, or desktop computers via SATA 6Gbps cables. Despite their compact 2.5" to 3.5" sizes, they feature a dynamic cache of up to 64MB. Having these types of storage devices in hand will improve work efficiency and productivity.

Improved Storage Capacity and Performance

There are SATA 6Gbps hard drives that can give users a blend of HDD and SSD functionality. A device that can give a synergistic effect on both storage units will surely offer a higher level of performance. Users will find drives with traditional storage capacity up to 22TB. Most of these drives also come along with NAND technology for enhanced performance.

The read-write speed is something that will give users optimum satisfaction. With the SATA 6Gbps interface, users can expect a read speed of up to 400MB/s. Not only that, but some drives also run at up to 10000 rpm. Even at that rate, they are generally quiet, and they generate less heat.

Drives that use the SATA 6Gbps interface have been built to learn users' most used applications effectively. This engineering allows them to load those applications faster. It also helps gaming consoles to load the games initially after users have launched the game. There is everything to get excited about when it comes to these drives.

The point of the SATA 6Gbps interface is to enhance the quality of traditional mechanical hard drives. They are available at different capacity choices and RPM choices.

Reliable Data Recovery

There are possibilities of data accidents such as accidental deletion, formatting, virus attack, unexpected power shutdown, and partition loss. If such losses occur, data recovery software can easily recover the data from SATA 6Gbps hard drives. Data can be easily recovered, undelete, and unformatted from these SATA hard drives

Dynamic Cache

The dynamic cache is one of these drives most impressive features despite not being so evident to users. It improves the performance of the SATA 6Gbps drives in real time with optimized cache allocation. This function allocates more cache towards the read and writes functions. That is why users will find that read and write speeds are usually almost equal.
