  1. No, I don't have to prove it. I'm talking about this possibility as the justification for the irregular writing pattern from the 16GB onwards. The burden of proof is always on the one that claims that something is impossible This argument is flawed, as manufacturers don't care about what you expect or what is your notion of mold.
  2. Care to elaborate and prove on what I'm wrong

    Fastest single SATA-II drive?

    Buying used disks is a bad idea. And why would you prefer an older, small, slower, noisier and less safe setup?
  4. 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"

  6. Sorry for the multiple posts!
  7. Western Digital 6400AAKS 640GB is the drive you are searching for! Mine costed 75€ and it is very fast!
  8. So SSD are also extremely vulnerable to filesystem fragmentation? Imagine NTFS trying to fill gaps. 64KB here, 256 there, 512 more. To save 832KB, it has to read-modify-write 30MB!
  9. I'd suggest an alternative. The Western Digital Caviar 6400AAKS 640GB 90$: http://www.newegg.com/Product/Product.aspx...N82E16822136218

    New OCZ SSD

    Ok then. But there's already an controller that allows it, please see here: http://www.storagesearch.com/ssd-slc-mlc-notes.html

    This is very interesting: Note how write performance starts to be very irregular at 25% of the drive. I wonder if the drive has both SLC and MLC. So, the first 16GB would be SLC and the remaining 48GB be MLC This has evident cost, performance and reliability advantages. - On NTFS, after windows installation, the MFT, pagefile and hibernation tend to be created at the beginning of the drive. - The beginning of the drive is most intensively used, it fills with time. So statistically, most of the access will be to the beginning of the drive - The odds of quickly finding small gaps for "Temporary Internet Files", small temp files, folders and a place for small writes typical of log files, are very high when the system scans the $Bitmap for free clusters So, this would make it much closer to SLC-only longevity, performance and reliability, being just a bit more expensive than MLC-only.
