ADATA Premier Pro SP920 SSD (512GB) Review – An Exceptional SSD At A Great Price


At Technology X, we test our SSD’s slightly different depending upon the drive’s marketed purpose, that of a consumer or an enterprise focused SSD.  For a consumer SSD, our goal is to test in a system that has been optimized with our SSD Optimization Guide, however, CPU C State alteration may or may not have occurred depending on the motherboard and BIOS configurations. Benchmarks for our consumer tests are that of fresh drives, so that we can verify that the manufacturer’s specifications match the SSD. Additionally, we also try to include links to the benchmarks used in our report so that you as the reader can replicate our tests to confirm that your SSD is top-notch.

This Test Bench build was the result of some great relationships and purchase; our appreciation goes to the below mentioned manufacturers for their support in our project. All of the components we use for testing and evaluation can be easily purchased at a relatively affordable price. The links provided below can assist in pricing, as well as availability for those of you who may find interest in our equipment.

PC CHASSIS: InWin 901 Mini-ITX Chassis
CPU: Intel i7 2600 CPU
CPU COOLER: Corsair H80 CPU Cooler
POWER SUPPLY: Cooler Master M2 Silent Pro 850W
SYSTEM COOLING: Corsair Chassis Fan
MEMORY: Crucial Ballistix Tactical Tracer 1600 MHz


The software used for today’s analysis is typical of many of our reviews and consists of ATTO Disk Benchmark, Crystal Disk Info, Crystal DiskMark, AS SSD, and PCMark Vantage.  In consumer reports, we prefer to test with easily accessible software that the consumer can obtain, and in many cases, we even provide links. Our selection of software allows each to build on the last and to provide validation to results already obtained.


Crystal Disk Info is a great tool for displaying the characteristics and health of storage devices. It displays everything from temperatures, to the number of hours the device has been powered, and even to the extent of informing you of the firmware of the device.

When taking a look at Crystal Disk Info, we can see that the SP920 features the S.M.A.R.T. attribute, which allows for us to monitor the health of the SSD over its lifespean, as well as TRIM and DevSleep. DevSleep allows for the drive to utilize very little power when the SSD is not in use. This would be  beneficial for those looking to upgrade the drive in their notebook/laptop.


ATTO Disk Benchmark is a relatively easy-to-use benchmark tool, which happens to be the benchmark of choice for many manufacturers. ATTO uses compressible data rather than random data, which results in higher performance and thus, higher benchmark scores. In our testing, we have selected the transfer size to range from 0.5KB to 8192KB, and have set the total length of the test to be 256MB.

 Our first benchmark tests shows us that the ADATA SP920 has read speeds of up to 563 MB/s, as well as write speeds of up to 513 MB/s, just over the listed specifications given to us by ADATA. This is definitely a good start to our testing.


Crystal Disk Benchmark is visually straightforward, and is used for measuring the speeds at which your storage device reads and writes in both compressible (oFill/1Fill) and random, mostly incompressible, data. Random data is more consistent with everyday use of a computer, such as transferring videos, pictures and music. We run the benchmark twice, using oFill data first, and then proceeding to test with random data. Since results typically return with nearly identical scores, we only include the results for random data samples.

Crystal DiskMark uses incompressible data in order to test the transfer speeds of the SP920. Incompressible data is that of videos and pictures, which cannot be compressed as easily as documents. With that being said, we already expect the performance of the SSD to be less than that of our previous test. The read and write speeds have returned with lower speeds, but this is not an overly concerning decrease.

ADATA has definitely proven that they are a force to be reckoned with so far this year. We first checked in with them at CES, where we got to see their newly coloured DRAM modules, wireless device charging technology, as well as their line up of new solid state drives. Shortly thereafter, ADATA released their SSD Toolbox software, which allows for you to monitor the health of your ADATA solid state drive. Today, ADATA goes one step further by releasing the ADATA Premier PRO SP920 SSD, and we have the opportunity to take an in-depth look at the 512GB model.…
