I just stuck a couple of FDMs instead of disks into gear I am building and their performance does not live anywhere near the claims of the flash lover crowd.
The write performance measured as "rm -rf" speed on UFS2 under BSD is about 5%-10% of the performance of a modern 7200rpm hard drive if not even less. It is so slow it is not even funny. OK, that is for a poor-man's 40 pin single write channel FDM disk replacement, not for a server drive, but even for this I would have never expected it to be so slow.
So can we have some independent benchmarks first run on proper server OS - Linux, BSD, Solaris or the like please and not synthetic sysoft garbage which says just about nothing about the real performance.
Then we can compare what is what. Until then the flash has only one advantage over disks - noise. Everything else (even power consumption) is actually worse.
