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 very decent results. You can see the peak read performance logged at roughly 5 GB/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. You're looking at close to 5.5 GB/sec here. It can keep up quite well, however, there is some clear disturbance in the force due to the HMB and QLC design.
