>When testing read performance on SeaweedFS, it basically becomes performance test your hard drive's random read speed. Hard Drive usually get 100MB/s~200MB/s.
There are no modern hard drives that get 100-200MB/sec on RANDOM reads. Random ends up being an exercise in IOPS not throughput, and there's absolutely no way you're pulling enough IOPS out of a SAS or SATA hard drive to get anywhere NEAR 100-200MB/sec on random workloads. I get the "it's the software dummy" thing everyone is so hyped about, but if you know THAT little about the underlying hardware and how it functions, you shouldn't be writing filesystems.
Also - what's the protection mechanism for files? If there is none, I literally have no idea what the purpose of this FS is. Under what circumstances would I need a giant slow data storage tier that has no redundancy to speak of?
