5. AS SSD benchmark
We move on with the AS SSD benchmark, which contains five synthetic as well as three practical tests. The synthetic tests determine the sequential and the random read / write performance of an SSD. These tests are carried out without using the operating system's cache. The Seq-test measures how long it takes to read and write an 1GB file. Most importantly, this sequential benchmark uses incompressible data for all of its transfers.
The Crucial P1 1TB SSD reached an overall high score of of 2532. Sequential speeds for the drive hit the 1777MB/s for reads and 1443MB/s write. The drive's 4K speeds reached 55MB/s for read and 133MB/s for write, which are close to what you could exect from a good SATA SSD:
The performance for the Crucial P1 1TB SSD in the sequential write test was good with the drive to meet its official specs, but not in par with the Adata SSD's result:
The P1 was slower that the rest SSDs in the 4K random write test, but gave a solid result in the 4K/64 thread write benchmark:
Next up we ran the Compression Benchmark built-into AS SSD. This test uses a mix of compressible and incompressible data and outputs both Read and Write throughput of the drive.
The Crucial P1 SSD showed a relatively stable behavior across the board, with some brief dips in the write graph:
