This article covers Dogfish 512GB SSD Mac mini M4用 内蔵ソリッドステートドライブ 最大3.

Overview

The Dogfish 512GB SSD for Mac mini M4 is a third-party internal solid-state drive designed specifically for Apple's Mac mini M4 (2024 model). It offers sequential read and write speeds of up to 3,300MB/s, significantly reducing boot times, application loading, and file transfer delays.
This SSD is aimed at users who find the standard storage capacity of the Mac mini M4 insufficient and want a cost-effective upgrade. Available in 512GB, 1TB, and 2TB variants, it provides ample space for photos, videos, and professional applications.
While it delivers NVMe-level performance at a fraction of Apple's upgrade pricing, it's important to note that this is a third-party product without official Apple support. The drive is exclusively compatible with the Mac mini M4 and cannot be used in other Mac models or standard M.2 slots.

Compatibility Guide

This SSD is exclusively designed for the Mac mini M4 (2024). Its physical shape and connector are tailored to the internal storage slot of that specific model. It will not fit any other Mac, including Mac mini M1/M2, MacBook Pro/Air, iMac, or Mac Pro.
The interface is PCIe 4.0 x4 with NVMe protocol, which is fully supported by the Mac mini M4's controller. However, macOS updates could potentially affect compatibility. Always check your macOS version before purchasing.
Installation is described as straightforward with the included manual, but it requires opening the Mac mini and handling delicate internal components. Anti-static precautions are essential, and the manufacturer explicitly disclaims responsibility for data loss or damage during installation.

Product Info

The Dogfish 512GB SSD for Mac mini M4 was released in late 2024 as a third-party storage upgrade. Pricing on Japanese online retailers is around ¥47,204 (as of September 2026), which is significantly cheaper than Apple's official storage upgrade options.
Positioned as an entry-to-mid-range compatible SSD, it offers practical performance for everyday use. The drive comes with a 1-year warranty and after-sales support. Sequential speeds are rated at up to 3,300MB/s, matching or exceeding the built-in SSD of the Mac mini M4.
However, the manufacturer does not disclose TBW (Total Bytes Written) or random IOPS figures, making long-term endurance assessment difficult. The controller and NAND type are also unspecified.

Best Use Cases

  • Users needing affordable internal storage expansion for Mac mini M4
    If the base 256GB is too small and you want internal storage without paying Apple's premium, this SSD is a solid choice. It provides fast NVMe speeds at a lower cost.
  • Budget-conscious creative professionals
    Photographers and video editors who need extra space for projects but can't justify Apple's high upgrade prices will find this drive appealing. However, they should be aware of the potential reliability trade-offs.
  • DIY enthusiasts comfortable with Mac mini disassembly
    If you have experience opening Macs and handling internal components, installation is manageable. Beginners should proceed with caution or seek professional help.

Things to Consider

This is a third-party product with no official Apple compatibility guarantee. macOS updates could potentially break compatibility or cause performance issues. The lack of published TBW ratings means you cannot estimate the drive's lifespan under heavy write loads.
Additionally, opening the Mac mini M4 may void your Apple warranty or AppleCare coverage. If you damage other components during installation, repair costs could be high.
Compared to Apple's official storage upgrade, this SSD is much cheaper but offers no guarantee of long-term reliability or support. Competitors like OWC or other Mac-focused SSD brands may offer better documentation and support, often at a slightly higher price.

FAQ

Q: Can I use this SSD in a Mac mini M2 or other Mac models?
A: No. This SSD is physically and electrically designed exclusively for the Mac mini M4. It will not fit or work in any other Mac.
Q: Is installation difficult?
A: The manufacturer claims it's beginner-friendly, but it requires opening the Mac mini and handling delicate parts. If you're not comfortable with such tasks, consider having a professional do the installation.
Q: How does the speed compare to Apple's built-in SSD?
A: The rated 3,300MB/s sequential speed is comparable to the Mac mini M4's stock SSD. However, real-world random access performance and sustained write speeds may differ, and long-term reliability is unverified.
