The test system used in this review is equipped with an AMD Ryzen 5 3700x CPU, MSI B550 GAMING PLUS motherboard, 16GB (8GB x 2) of Crucial Ballistix 3200 MHz DDR4 memory, Crucial P5 1TB SSD and a GIGABYTE GeForce GTX 1060 WINDFORCE OC 6G graphics card. For the operating system, I used the latest version of Windows 10 Pro.

To test the performance of ADATA's XPG ATOM 30 SSD, I ran a series of benchmarks using CrystalDiskMark, HD Tach RW, ATTO Disk Benchmark, AS SSD, HD Tune Pro, Anvil's Storage Utilities, Iometer and PCMark. For comparison, I've also included test results from the ADATA XPG GAMMIX S70 Blade, Crucial P5 Plus, Plextor M10PY, ADATA XPG GAMMIX S70, Sabrent Rocket 4 Plus, WD_BLACK SN850, Silicon Power US70, ADATA XPG GAMMIX S50 Lite, Samsung 980, Silicon-Power UD70, Crucial P2, SK hynix Gold P31, Crucial P5, ADATA SWORDFISH, ADATA FALCON, Lexar NM610, Silicon Power P34A60, Patriot P300, Plextor M9PG Plus, Plextor M9PY Plus, ADATA XPG SX6000 Pro, Western Digital WD_BLACK SN750, Lexar NQ100, Samsung 970 EVO Plus, ADATA XPG SX8200 Pro, Crucial P1, ADATA XPG SX8200, Western Digital WD_BLACK NVMe, Samsung 970 EVO, Samsung 970 PRO, Plextor M9Pe, Plextor M8Se, Patriot Hellfire, ADATA XPG SX8000, Samsung 960 PRO, Toshiba OCZ RD400, Samsung 950 PRO, Samsung 870 EVO, Samsung 870 QVO, Silicon Power PC60 and SK hynix Gold S31.

As I mentioned earlier, the ATOM 30 uses Realtek's RTS5766DL controller chip. Looking at the screenshot above, you can see that it performs equally well with both incompressible (0%) and compressible (100%) data.

The Ultimate SU670 uses Realtek's RTS5735DLQ controller chip. Like the RTS5766DL, it performs equally well with both incompressible (0%) and compressible (100%) data.

CrystalDiskMark 8.0.4:

First, I ran a few quick tests using CrystalDiskMark. This benchmark measures the performance of a storage device by testing its sequential and random read and write speeds. For this test, we're using the peak and real world profiles.

According to ADATA, the 1TB ATOM 30 is capable of reading at 2,500 MB/s and writing at 2,000 MB/s. As you can see, the drive had no problems reaching these speeds in CrystalDiskMark's sequential read and write tests.

As you'd expect, the Ultimate SU670 isn't nearly as fast as the ATOM 30. Nevertheless, it was still able to read at 546 MB/s and write at more than 516 MB/s. 

HD Tach RW 3.0.4.0:

Next, I used HD Tach to test the ATOM 30 kit's read, write and burst speeds as well as its random access time and CPU usage.

ADATA Ultimate SU670 250GB

Like most other TLC-based SSDs, the ATOM 30 and Ultimate SU670 use some sort of SLC caching. In the case of the ATOM 30, the drive starts writing at about 1,000 MB/s and then drops to about 250 MB/s when the write operation exceeds the size of the cache.

ATTO Disk Benchmark 4.01:

I also used ATTO Disk Benchmark to test the ATOM 30 kit's sequential read and write speeds. The tests are run using blocks ranging in size from 512B to 64 MB and the total length set to 256MB.

ADATA Ultimate SU670 250GB

When tested with ATTO, the ATOM 30's read speeds topped out at about 2.52 GB/s and its write speeds at 1.94 GB/s.
