Kioxia Toshiba RC500 500GB SSD Review

To test 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 drive reading from & writing to a 256GB Samsung SSD850 PRO.

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


Our real-life file transfer test proved no obstacle for the drive. As always with this test, it’s dealing with the small file sizes in the 60GB Steam, 50GB File and 10GB Audio folders that slows the drive down.

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 512GB Toshiba OCZ RD400.


Taking the SATA drive out of the equation allows the RC500 to show a bit more of what it’s capable of. Best write performance came with the 60GB iso transfer at 1,666MB/s while the best read performance came with the 8K Movie Scenes transfer at 1,436MB/s.
