Comparisonīy virtue of the larger ~65 GB SLC cache, the Aura P12 could maintain a more stable write speed in HD Tune, at around 1800 MB/s. Write speed stayed above 2 GB/s most of the time. It took the SSD 4.76 seconds to complete the copying of the three files, sized around 15 GB. The drive also experienced thermal throttling at the later part of the test, causing the read speed to fluctuate and drop to around 2000 MB/s. Speed reduced from 2500 MB/s to 1000 MB/s. Simulating a huge 100 GB file transfer in HD Tune, we could observe that the Aura P12 is configured with about 65 GB of SLC cache, which write performance started to decrease after the cache was saturated. The Aura P12 got about 3200 MB/s for read and 2800 MB/s for write. In ATTO Disk Benchmark, the speeds became stable, once the file size increased to 128 KB or above. IOPS number represents how well a drive handles random input and output operations. It achieved a maximum of 604668 IOPS in read and 495511 IOPS in write. At greater queue depth, the random 4K performance was boosted to 1930 MB/s and 2360 MB/s. We saw more moderate results in AS SSD Benchmark, with sequential speeds at around 2500 MB/s. FYI, most SATA-based SSDs often sits at under 300 MB/s. Random 4K operations (QD 32) was lowered to about 760 MB/s and 680 MB/s. The Aura P12 was able to reach the claimed sequential read/write speeds in CrystalDiskMark, at around 3470 MB/s and 3030 MB/s.
