Sort of. Random writes are fine as long as they are as large as the physical write block size (not the virtual 512b or 4k) and there's a queue depth high enough to keep the drive busy. Unless you are lucky enough to have Intel's (no longer made) Optanes that give nearly 100% of performance with low queue depths.
This avoids the ugly read/modify/write, as well as much of the behind the scenes magic for minimizing write amplification and shuffling blocks around.
