There is actually a VERY easy solution nowadays. SSD(s)

It doesn't matter if files are continuous or not, SSDs don't care (at
least the better ones)

If you care about "worst case" write performance, zap the whole thing
before usage (a.k.a.: trim) and write in chunks that are sized and
aligned to erase-blocks (or just write in big chunks like 1MB or more).
That should be more or less be enough to prevent latency spikes, that
CAN plague SSDs.

What exactly you need obviously depends on the usual factors:
Needed sustained read/write bandwith, size, money, etc. etc.
