Very true. Although they also say it's entirely their firmware code that's the reason behind the 23% improvement on sequential read performance - from that you could reasonably infer that without Synology's apparent magic fairy dust, that 23% improvement doesn't exist. I'd be questioning Toshiba's firmware coders if that was genuinely the case - even though I know that Synology likely didn't write a single line of firmware, it was Toshiba. And perhaps it's prioritised sequential read performance. Although arguably, I wouldn't say sequential read performance is the priority for a RAID array, but who knows.
