As BD-RE can be formatted for direct read/write access like a flash drive, I decided for curiosity to run a few benchmarks on a BD-RE, in this case a Verbatim 25GB 2x BD-RE using an LG BH10LS30. It's commonplace to see benchmarks carried out on USB flash drives, external hard disks, NAS network drives and so on, so I thought, why not benchmark a UDF-formatted BD-RE?
ATTO first threw up a message saying to change the starting sector size to 2KB and then ran the benchmark:
CrystalDiskMark didn't show the Blu-ray drive letter, but after figuring out a workaround, this is its result:
I'm curious to try out some file read/write tests, but just looking at these two benchmarks, direct read/write access appears to be extremely slow even when compared to slowest USB flash drives available.
