This article covers 東芝(TOSHIBA) 3.5インチ HDD 4TB 内蔵型 デスクトップPC 向け 省電力モデル 【国内正規代理店品】 2年保証 DT02ABA400-2YW.

Overview

The TOSHIBA DT02ABA400-2YW is a 3.5-inch internal hard drive with a 4TB capacity, designed as a low-power model for desktop PCs. It spins at 5400rpm and carries a 128MiB buffer, making it a practical choice for bulk storage and backup duties.
This unit is sold as a new product through authorized domestic channels in Japan, and it comes with a 2-year warranty. The "-2YW" suffix in the model number identifies this particular retail package.
In the current storage market, this drive sits in the entry-to-mid tier, appealing to users who need large capacity without spending a premium. While SSDs dominate as primary drives, a 4TB HDD like this remains a cost-effective solution for mass data storage.

Compatibility Guide

This is a 3.5-inch SATA hard drive, so it fits into standard desktop PC drive bays. It can also be installed into 3.5-inch compatible external enclosures or NAS units.
The interface is SATA, which is natively supported on virtually all modern motherboards. No additional expansion cards are required for a typical desktop build.
Power consumption is modest for a drive of this class. A single SATA power connector from a standard ATX power supply is sufficient. If you plan to run multiple drives, check that your PSU has enough SATA connectors and overall capacity.

Product Info

The DT02ABA400-2YW was released in April 2020. Its specifications include a 4TB capacity, 5400rpm spindle speed, and a 128MiB buffer. Physical dimensions are approximately 147 mm in length, 102 mm in width, and 27 mm in height, with a weight of about 680 g.
The low-power design makes it suitable for intermittent use rather than 24/7 operation. It is positioned as an entry-to-mid tier option for users who want large capacity at a low cost.
It is sold through authorized domestic channels in Japan, and the package includes a 2-year warranty.

Best Use Cases

  • Users who need to store large amounts of photos, videos, or other data. The 4TB capacity offers plenty of room at a lower cost per gigabyte than an SSD. This is not for those who need a fast primary drive for frequent read/write operations.
  • People who want to build an external backup drive using a 3.5-inch enclosure. The 5400rpm low-power design is well suited for a drive that stays connected for periodic backups. Not ideal for portable use where the drive is frequently moved.
  • Desktop users who want a secondary drive for game libraries or work files. It adds substantial capacity cheaply, though it won't match SSD speeds. Gamers who prioritize the fastest load times should look elsewhere.

Things to Consider

This is a 5400rpm low-power model, so sequential access speeds are more modest than 7200rpm drives. Using it as a primary OS drive will result in slower boot times and application loading.
Being a 3.5-inch drive, it will not fit in laptops or cases that only support 2.5-inch bays. Always verify your PC's bay size before purchasing.
For long-term archival storage, this drive offers excellent value. However, for workloads involving frequent random access or environments where noise is a top priority, an SSD or a 2.5-inch HDD might be a better fit.

FAQ

Q: Can this HDD be installed in a PS4 or PS5?
A: No. The PS4 only supports 2.5-inch drives, and the PS5 is limited to 2.5-inch or M.2 SSDs. This 3.5-inch drive is intended for desktop PCs or 3.5-inch compatible external enclosures.
Q: What should I consider when using this in an external enclosure?
A: Choose a 3.5-inch compatible enclosure. Most connect via USB and will be recognized by your PC automatically. Since 3.5-inch drives require more power, pick an enclosure with an AC adapter for stable operation.
Q: How much data can 4TB hold?
A: As a rough guide, that's enough for roughly 1,000 full-HD movies or several hundred thousand photos from a digital camera. The actual number depends on the bitrate and compression of your files.
