Crucial P1 SSD Review: Nimble NVMe Storage For Pennies Per Gig
Crucial P1 NVMe SSD: SANDRA And ATTO Benchmarks
Next we used SiSoft SANDRA, the the System ANalyzer, Diagnostic and Reporting Assistant for some quick tests. Here, we used the Physical Disk test suite and provide the results from our comparison SSDs. The benchmarks were run on clean drives that lacked any partitions. Read and write performance metrics are detailed below.

ATTO is another "quick and dirty" type of disk benchmark that measures transfer speeds across a specific volume length. It measures raw transfer rates for both reads and writes and graphs them out in an easily interpreted chart. We chose .5KB through 64MB transfer sizes and a queue depth of 6 over a total max volume length of 256MB. ATTO's workloads are sequential in nature and measure raw bandwidth, rather than I/O response time, access latency, etc.
The Crucial P1 remains competitive the with AData and Intel drives in the read test here, until it hits the 2MB transfer size, at which point its performance tapers off. The same can be said in the write test, though the P1's performance drops off at about the 16K mark and ends up trailing the rest of the way.
