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 (readback of fame content) shows good results. You can see the peak read performance logged at ~3000 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 we see a lot of bounces here. The SSD can keep up in writes but shows quite a bit of write fluctuation, this likely is the effect of lacking a big enough RAM cache with the pSLC cache writing out. We still hit an average ~2500 MB/sec marker which you can't really complain about at this price level.
