The SC750 External SSD
The ADATA SC750 features a compact, plastic body with a Black Titanium finish that resembles brushed metal. While the casing isn’t made of premium materials, the design is clean and modern, with branding kept minimal through silver and black logos on the front. Its pocket-sized form factor and rounded edges make it easy to handle and carry, which suits users who need portable storage on the go.
On the back, the drive includes a retractable USB Type-C connector controlled by a manual slider—similar to older-style USB flash drives. This eliminates the need for a separate cap and helps protect the connector during travel. The rear also contains printed details such as capacity and manufacturing origin. Overall, the build is simple and functional, favoring practicality over flashiness.
Hardware
Out of curiosity—and for the sake of our readers—we pried open the ADATA SC750, though it’s worth noting this isn’t something users are advised to do. Inside, the layout is compact and efficient. One side of the PCB features an ADATA-branded NAND flash chip and a USB Type-C port soldered directly onto the board. While it doesn’t use a traditional M.2 layout, the internal design clearly draws from SSD architecture, allowing high-speed components to fit into a USB-sized form factor.
On the flip side of the PCB, there’s a thermal pad placed over the key component to help manage heat during heavy use. However, since the SC750’s housing is entirely plastic, there’s no built-in metal to aid with heat dissipation. It gets the job done for most tasks, but there’s definitely room for improvement here. Technically, modders could try adding a thin metal layer for better cooling—but that’s not recommended for the average user.
Powering the drive is the Silicon Motion SM2320 controller, a native USB 3.2 Gen2 solution tailored for portable SSDs. This controller supports up to four NAND flash channels, but the actual configuration may vary depending on the device. By removing the need for a separate USB-to-PCIe bridge chip, the SM2320 helps reduce power consumption and manufacturing cost. It also includes NANDXtend ECC for error correction, and offers support for AES 256-bit encryption as well as TCG Opal compliance for secure storage. While the controller is technically capable of reaching up to 2,100 MB/s, performance on the ADATA SC750 is capped by its 10Gbps interface, which delivers up to 1,050 MB/s under ideal conditions.
Mac Mini M4 Benchmark
We tested the ADATA SC750 on a Mac Mini equipped with Apple’s latest M4 chip—a device known for its strong performance and efficient architecture. However, like many Apple systems, it’s limited by the high cost of internal storage upgrades.
Our test unit had 512GB of internal SSD and 16GB of unified memory, so adding a 1TB high-speed external SSD provided a more cost-effective way to expand storage for tasks like media editing, file transfers, and running lightweight external apps. So, let’s see how it performs.
Using Blackmagic Disk Speed Test, the SC750 reached write speeds of 893.5 MB/s and read speeds of 906.2 MB/s, which, while slightly below the advertised 1,000+ MB/s, still represents solid real-world performance for a USB-based SSD.
We also ran AmorphousDiskMark, a macOS benchmark tool similar to CrystalDiskMark, to get a more detailed look at read/write behavior. The SC750 posted 974.32 MB/s read and 973.77 MB/s write in sequential QD8 tests. Lower queue depth and random 4K tests showed more modest results, but remained in line with expectations for a USB SSD, particularly one using a DRAM-less controller design optimized for efficiency.
Overall, the ADATA SC750 performed well on macOS, particularly in sequential workloads such as file transfers, media playback, and backups. In both synthetic and real-world tests, it came close to or matched its advertised speeds of up to 1,000 MB/s, showing that it can reliably deliver on its performance claims.
PC Benchmark
On our Windows 11 desktop, we tested the ADATA SC750 using several benchmark tools to evaluate its performance in a typical PC environment.
In CrystalDiskMark 8.0.6, the drive exceeded its advertised read speed, reaching 1,065 MB/s read and 972 MB/s write in sequential tests. It also showed decent random 4K performance, particularly in multi-threaded workloads, suggesting it can handle a mix of media transfers and light application usage reliably.
To gain further insight into real-world and latency-sensitive operations, we ran AS SSD Benchmark, where the SC750 delivered 985 MB/s read and 875 MB/s write sequential speeds. Access times remained low at 0.058ms (read) and 0.103ms (write), with a total score of 810. These results reflect stable performance under sustained load, with strong multi-threaded 4K throughput—suitable for tasks like editing, portable software usage, or even bootable operating systems.
Lastly, in ATTO Disk Benchmark, the drive performed consistently across various block sizes. Read speeds peaked around 1,018 MB/s, while write speeds stabilized at 929 MB/s starting from 512KB block sizes. Performance scaled predictably, showing that the SC750 is optimized for large file transfers and high-volume data tasks. While smaller files show the expected slower speeds, the drive still performs well across a broad range of real-world scenarios.
Copy and Paste Benchmark
Benchmarks are great, but nothing beats real-world file transfer tests when it comes to evaluating everyday performance. To simulate a common use case, we transferred a single 18.27GB file back and forth between the host device and the ADATA SC750.
Here are the results:
| Device | Transfer Time (to USB) | Transfer Time (from USB) |
| Mac Mini M4 | 24.47 seconds (763.97 MB/s) | 20.93 seconds (893.79 MB/s) |
| PC Desktop | 25.03 seconds (747.02 MB/s) | 24.02 seconds (778.85 MB/s) |
| iPhone 16 Pro Max | 22.11 seconds (846.13 MB/s) | 22.14 seconds (844.95 MB/s) |
Across all three devices—Mac, PC, and iPhone—the ADATA SC750 consistently hit over 740 MB/s, with the iPhone 16 Pro Max surprisingly pulling ahead in write speed. This makes the SC750 not just a speedy backup solution, but also a solid performer for transferring large video files, game assets, or system images without the wait.
Conclusion
The ADATA SC750 hits a sweet spot for users who need fast, portable storage without the hassle of bulky enclosures or sky-high prices. At ₱4,095 for the 1TB variant and ₱2,595 for the 500GB, it’s not the cheapest option on the market, but it’s certainly one of the most practical—especially when considering its 1GB/s performance in such a compact USB form factor.
Yes, there are faster options out there, like 40Gbps enclosures pushing 3GB/s speeds, but those typically require a separate SSD and enclosure, which drives the total cost significantly higher. The SC750, on the other hand, offers a plug-and-play solution that’s ideal for photographers, video editors, power users, and even casual users who just want fast file transfers between devices.
If your priority is speed and portability without the extra clutter, the SC750 is a solid pick. It’s fast enough to handle photography workloads, 4K video recording, or even function as a bootable OS drive. With 1TB of space in such a small package, it’s also perfect for those who need to transfer large files between devices quickly and conveniently—no cables, no setup, just plug and go. It will also be interesting to see how it performs with future devices like the upcoming Nintendo Switch 2—something we’ll definitely revisit once that system becomes available.
