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 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 ~6000 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 yeah, you can see that a too-small pSLC buffer does not really hinder the write performance. It can keep up quite well, though. Further monitoring shows that the pSLC cache is ~48 GB in size but keeps on going sufficiently fast for a while longer.
