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 great results. You can see the peak read performance logged at ~3150  MB/sec. That is great to witness tbh with a 12 cents per GB TLC SSD


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 yeah, you can again see that the write performance is somewhat hindered by a too-small pSLC buffer. It can keep up quite well though. Further monitoring shows that the pSLC cache is almost 50 GB in size at 2800 MB/sec and then drops to roughly 1100 MB/sec sustained, which is still good.
