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 peak read performance logged at just over 500 MB/sec with an average closer to 450 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 measured at that ~40 GB marker. Up to that point 440 MB/sec, and then perf drops to a very ordinary 250~300 MB/sec. The results here are very stuttery meaning the SSD has a lot of issues coping with the workload.
