In your article:
No, IMHO it's not it! When deleting files, temp, temporary internet files, copies, etc... gaps are created. Then, to create new files NTFS tries to find free space from the beginning of the drive. Therefore fragmentation starts very soon, you don't need to have low disk space.
Another thing, IMHO the OCZ core has got to have both SLC and MLC. High grade and cheapo flash in multi-channel or whatever. And the first 25% of the drive is SLC. The MFT is there, NTFS will soon find small files will fit. And every HDTune benchmark shows the same.
If you wish, create 2 partitions: 1 smaller than 16GB and the 2nd using the rest. The second will hit the lala land, it will not be funny to have the $mft and $logfile there
And why the irregular pattern? The HDTune block size. It is configurable on v2.54 and above, go to Options->Benchmark. They recommend HDTach on their paper, because maybe the block size is 8MB, no wonder! Look at the OCZ Specs, Random Write ~= 18MB/s and look at the 8MB value on your "Random Write Performance: Actual vs Predicted"
