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 continious 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. 

A small brief dip in read performance during the 64GB file read (playback of video content). You can see the advertised peak read performance logged at 1640 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 as you can see that's again measured at that ~40 GB marker. Up to that point 1673 MB/sec, and then perf drops to roughly 600 MB/sec.
