Testing

Silicon Power Ace A55 1TB 7mm SATA 2.5” SSD

Initialized as GPT and formatted as NTFS in windows, we get a useable space of 953GB.

 

CrystalDiskInfo

An HDD/SSD utility software which supports a part of USB, Intel RAID, and NVMe.

CrystalDiskInfo shows we are connected to the host machine at SATA-III 6.0Gbps as expected.

 

ATTO Disk Benchmark

“As the industry's leading provider of high-performance storage & network connectivity products, ATTO has created a widely-accepted Disk Benchmark freeware utility to help measure storage system performance. As one of the top tools utilized in the industry, Disk Benchmark identifies performance in hard drives, solid-state drives, RAID arrays as well as connections to storage. Top drive manufacturers, like Hitachi, build and test every drive using the ATTO Disk Benchmark"

ATTO shows just a bit slower than the advertised specs, but not really enough to matter in real-world use.

 

CrystalDiskMark 6.0

“CrystalDiskMark is designed to quickly test the performance of your hard drives. Currently, the program allows measuring sequential and random read/write speeds."

CrystalDiskMark shows the A55 pulling ahead in read speeds by about 25MB/s and write speeds by more than 10%.

 

Anvil's Storage Utilities

Anvil's Storage Utilities is a powerful tool that was designed in order to provide you with a simple means of assessing the read and write performance of your Solid State Drive or Hard Disk Drive.

The benchmark tool helps you monitor and check the response time of your unit as well as view the system information collected using Windows Management Instrumentation (WMI).

The overall score is great for a SATA SSD, not quite the highest we’ve seen, but on the upper end.

AS SSD

The AS SSD benchmark determines the performance of Solid State Drives (SSD). The tool contains six synthetic and three copy tests.

The synthetic tests determine the sequential and random read and write performance of the SSD. These tests are carried out without using the operating system cache. In Seq-test the program measures how long it takes to read a 1 GB file to write respectively. 4K test the read and write performance is determined at random 4K blocks. The 4K-64 corresponds to the test Third 4K procedure except that the read and write operations are distributed to 64 threads. This test should SSDs pose with Native Command Queuing (NCQ), differences between the IDE operation mode where NCQ is not supported, and the AHCI mode. The additional compression test can measure the power of the SSD in response to the compressibility of the data. This is especially for the controllers that use to increase the performance and life of the cell compression, important.

In the first three synthetic tests and the compression test, the size of the test file 1 GB. Finally, the access time of the SSD is calculated, wherein the access to read over the entire capacity of the SSD (Full Stroke) is determined. The write access test, however, is done with a 1 GB big test file.

AS SSD always shows a bit lower than most of our other tests but shows close to rated speeds here with a decent 691 points as a total score.
