Solidigm P44 Pro 1TB SSD Review

To test the real-life performance of a drive we use a mix of folder/file types and by using the FastCopy utility (which gives a time as well as MB/s result) we record the performance of the drive reading from & writing to a 256GB Samsung SSD850 PRO.

We use the following folder/file types:

100GB data file.
60GB iso image.
60GB Steam folder – 29,521 files.
50GB File folder – 28,523 files.
21GB 8K Movie demos.
12GB Movie folder – 24 files (mix of Blu-ray and 4K files).
11GB 4K Raw Movie Clips (8 MP4V files).
10GB Photo folder – 621 files (mix of png, raw and jpeg images).
10GB Audio folder – 1,483 files (mix of mp3 and .flac files).
5GB (1.5bn pixel) photo.
Blu-ray movie.

Solidigm's P44 Plus averaged 550MB/s for writes when dealing with the larger file size transfers and 465MB/s when reading the data back. However, It's not quite as efficient when dealing with smaller file sizes, averaging 299MB/s for writes and 391MB/s for reads. As normal, the 50GB file folders are the slowest; 253MB/s writes and 280MB/s reads.

To get a measure of how much faster PCIe NVMe drives are than standard SATA SSD's we use the same files but transfer to and from a 2TB Kioxia Exceria Plus drive:

Switching to an all-NVMe environment, transfer speeds increased dramatically and access times plummeted. Ten of the write transfers topped 2GB/s, the fastest being the 3,092MB/s for the 5GB/s image transfer. Nine of the read transfers topped 2GB/s, again the fastest being for 5GB/s image transfer at 2,673MB/s,
