SSD Performance Video Capture

SSD Performance Video Capture

if there is one workload really stressful for any storage unit, it has to be video capturing. In this test, we simulate a 5K capture workload and test + log continuous writing towards the storage unit. The test is 64 GB in size and will expose any TLC/QLC write holes an SSD has, up-to that 64 GB of course. Basically we're sending captures 5K frames towards storage and have it write/read as fast as it can. 

This 64GB file read test (playback of video content) shows incredible results. You can see the peak read performance logged at ~523 MB/sec .  

Writing (capturing video data) then, we write 64GB. Any TLC/QLC write holes (the moment when your SSD runs out of buffers) will be exposed here and albeit bouncing a bit here and there, the SSD manages to keep up notably well averaging out in the 0.4'ish GB/sec domain.
