The STmagic SPT30 features a USB Type-C interface that supports not only high-speed data transfer of up to 480 MB/s read and 450 MB/s write but also compatibility for both Windows and Mac OS operating system, as well as USB OTG for supported Android devices.

Benchmark and Test Results

The software in use for today’s analysis are Crystal Disk Info, ATTO Disk Benchmark, Crystal Disk Mark, AS SSD, Anvil’s Storage Utilities, AJA, TxBench, as well as true data testing. Our selection of software allows each to build on the last and to provide validation to results already obtained.

CrystalDiskInfo Benchmark

CrystalDiskInfo is a great tool for displaying the characteristics and health of storage devices. It displays everything from temperatures, the number of hours the device has been powered, and even to the extent of informing you of the firmware of the device. This CrystalDiskInfo result confirms that our STmagic SPT30 512G Mini Portable M.2 SSD is 512GB, SATA/600, and UASP compatible.

CrystalDiskMark Benchmark

CrystalDiskMark Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples. Once again, we see very strong performance of 291.7MB/s read and 384.6MB/s write, however, it would have been nice to see low 4k random results just a bit higher.

ATTO Disk Benchmark

ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 1GB and test both the read and write performance of various transfer sizes ranging from 512 bytes to 64MB. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results. Our ATTO results are very strong and display a steady performance increase as sample sizes increase. In addition, the performance results of 428.45MB/s read and 392.34MB/s write confirm listed STmagic SPT30 512G Mini Portable M.2 SSD specifications.

AS SSD Benchmark

Widely used SSD benchmarking utility that uses incompressible data to simulate the worst possible scenario for an SSD and thus giving a much lower sequential read and write speed result than what has been stated by the manufacturer as a result of the heavy workload. Both tests result show that we’re able to achieve the advertised 349.14 MB/s read and 377.14 MB/s write with the STmagic SPT30, slightly higher in some case. The difference isn’t much of course, but we can say that the performance is about the same as most SATA III SSD you’ll find in the market now.

Anvil’s Storage Utilities

Anvil’s Storage Utilities (ASU) are the most complete test bed available for the solid-state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.

AJA System Test

The AJA Video Systems Disk Test is relatively new to our testing and tests the transfer speed of video files with different resolutions and Codec.


TxBench is one of our newly discovered benchmarks that we work much the same as Crystal Diskmark, but with several other features.

MiniTools Disk Benchmark

Tested with a Disk Benchmark that tests both read-write, continuous, and randomly written readings simultaneously. Scores of random readings will vary, but still in good criteria. As for the test scores with continuous reading, it is also at a high rate, which is over 300MB / s. It makes us confident that this drive really works quickly and is normal.

File Transfer Test

For this test, we’ll be using different types of data that we’re dealing with every day – image, video, compressed file, etc just to see how will it perform. 300 MB/s is about the highest read and write speed we’re able to achieve with the STmagic SPT30 512G. Although it’s not exactly the same as the advertised speed, it’s still at least 100 MB/s faster than most of the portable SSD that is still based on the USB 3.1 Gen 1 (formerly known as USB 3.0).

300 MB/s might be the peak performance we’re able to achieve with our system, but the type of data, storage device, and interface used plays an equally important role that will affect the performance overall. If you’re copying the data from or to a mechanical hard drive, 200 MB/s is probably the highest you can reach on both the read an write speed.


Experimental measurement of the read /writes speed of the STmagic SPT30 512G Mini Portable M.2 SSD. The overall performance of this Portable is in good standing as it should be. The test speed from AS SSD will read up to 520 and can be written at 460 megabytes per second. Which, if looking at the SSD that is inside the SATA III standard, can see that the fastest connection standard is this While testing, the chassis of the STmagic SPT30 512G Mini Portable M.2 SSD That is quite hot The test has some speed. I try to use it in general. I can’t find any problems. But if we use general work, I don’t find any problems at all.

The STmagic SPT30 512G Mini Portable M.2 SSD is an excellent option for those users or professionals who need to operate with their data on different computers, as it offers excellent portability with its compact dimensions and light weight coupled with a sensational performance. USB 3.1 Gen1 connectivity makes it compatible with virtually any computer, it is better not to use a Gen2 port because they often cause problems with many devices that are not, limiting performance in this case. It is an option of portable storage devices that are interesting if you want a higher speed than USB Flash Drive but not much larger.
