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 6.0 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 6 GB/sec here. It can keep up quite well, however, there is some disturbance in the force due to the HMB design.
