This article covers 東芝 内蔵HDD 3.5インチ 3TB PCモデル DT01ACA300-2YW 【国内正規代理店品】 2年保証 SATA 6Gbps対応.

Overview

The Toshiba DT01ACA300-2YW is a 3.5-inch internal hard disk drive with a 3TB capacity, spinning at 7200RPM. It uses CMR (Conventional Magnetic Recording) technology, which offers more consistent random write performance compared to SMR (Shingled Magnetic Recording) drives. The interface is SATA 6Gbps, with a stated data transfer rate of 1815 Mbps (approximately 227 MB/s), which is typical for this class of HDD. As an officially authorized Japanese domestic product, it comes with a 2-year manufacturer warranty, providing peace of mind for long-term use. This drive is designed for desktop PC data storage, suitable for storing videos, music files, backups, or as a game installation drive. 3TB gives you enough space for roughly 600–700 full-HD movies, after accounting for the OS and applications.

Compatibility Guide

The DT01ACA300-2YW is a standard 3.5-inch SATA internal HDD. It connects via SATA 6Gbps and is backward compatible with SATA II (3Gbps) and SATA I (1.5Gbps) ports, though performance will be limited to the slower port speed. Power is supplied through a standard SATA 15-pin power connector. Power consumption is modest: about 3.5W at idle and 6.0W during seek, so even a 300W PSU can handle it easily. Because it is a 3.5-inch drive, it will not fit in 2.5-inch bays found in most laptops or small-form-factor cases. Ensure your desktop case has at least one 3.5-inch drive bay available.

Product Info

The Toshiba DT01ACA300-2YW has been a long-selling model since around 2020. It sits in the entry-to-mid-range segment for bulk data storage, offering a low cost per gigabyte compared to SSDs. The drive comes with a 2-year warranty and is widely available from major online retailers like . Key specifications: 3TB capacity, 7200RPM spindle speed, 64MB cache, CMR recording, SATA 6Gbps interface, weight approx. 680g. Noise levels are rated at 26dB during seek and 20dB at idle, making it reasonably quiet.

Best Use Cases

Bulk file storage – Ideal for archiving photos, videos, and backups. It offers large capacity at a low cost per terabyte. Game library drive – While load times are slower than SSDs, texture streaming during gameplay is fine. Good for expanding your Steam library without breaking the bank. Budget-conscious PC builders – Excellent value for a dedicated data drive. Much cheaper per gigabyte than any SSD. Not recommended for OS or frequently used applications – Boot times and app launches will be significantly slower compared to an SSD. Pair this HDD with an SSD for the system drive.

Things to Consider

This drive uses CMR technology, which means random write performance is stable and suitable for RAID or NAS use. However, sequential write speeds are slightly lower than some SMR competitors, but that trade-off is worthwhile for reliability. Competitors include the Seagate BarraCuda 3TB (ST3000DM008) and Western Digital Blue 3TB (WD30EZRZ). The Toshiba drive is often priced slightly lower, making it a strong value choice. 3TB is sufficient for most home users, but if you work with 4K video or run a large NAS, consider 4TB or larger models. Also, being a 7200RPM drive, it produces slightly more vibration and noise than 5400RPM models, so it's best to mount it securely in a case with rubber grommets. ## FAQ
Q: Can I use this HDD as an external drive for PS4 or PS5? A: Yes, if you put it in a 3.5-inch external enclosure. PS4/PS5 support USB 3.0 or higher, and you can store and play games from it. However, PS5 games can only be played from the internal SSD, so external storage is limited to PS4 games. Q: Will it work on a motherboard with SATA 3Gbps? A: Yes, it is backward compatible. The drive's max transfer rate (~227 MB/s) is below the SATA 3Gbps limit (~300 MB/s), so there is no bottleneck. Q: Is this drive suitable for RAID 1 (mirroring)? A: Yes, because it uses CMR. SMR drives can suffer from very slow rebuild times in RAID arrays, but CMR drives like this one are well-suited for RAID configurations.
