SSD Performance Video Capture
SSD Performance Video Capture
If there is one type of job that may be extremely taxing on any storage unit, it has to be video capture. Here we apply a 5K capture workload and the test + log continuous writing towards the storage unit are both simulated in this experiment. The test is 64 GB in size and will reveal any TLC/QLC write holes that an SSD may have, provided that the SSD has a capacity more than 64 GB. Essentially, we're sending 5K frames to storage and requesting that it write and read as quickly as possible.
This 64GB file read test (readback of fame content) shows great results. You can see the peak read performance logged at ~6200 MB/sec.
After that, we write 64GB of data. Any TLC/QLC write holes (the point at which your SSD runs out of buffers) will be exposed in this section of the configuration. often the combination and number of active used controller channels, pSLC, and DRAM buffers are proficient in managing or even resolving the problem. You can see that the SSD does rin into a TLC write hole, however at 1600 MB/sec is still writing plenty fast for even the fastest NAS units available on the market.
