Die 64er lag bei ca 158 und die 128er bei ca. 280. Jetzt 148 bzw. 264. Immerhin ein Sprung von 10-15Euro.
Tach,
Würde meiner Workstation gern eine SSD spendieren. Und zwar das Supertalent Ultradrive ME

MojoKid writes "A common concern with the current crop of Solid State Drives is the performance penalty associated with block-rewriting. Flash memory is comprised of cells that usually contain 4KB pages that are arranged in blocks of 512KB. When a cell is unused, data can be written to it relatively quickly. But if a cell already contains some data, even if it fills only a single page in the block, the entire block must be re-written. This means that whatever data is already present in the block must be read, then it must be combined or replaced, and the entire block is then re-written. This process takes much longer than simply writing data straight to an empty block. This isn't a concern on fresh, new SSDs, but over time, as files are written, moved, deleted, or replaced, many blocks are a left holding what is essentially orphaned or garbage data, and their long-term performance degrades because of it. To mitigate this problem, virtually all SSD manufacturers have incorporated, or soon will incorporate, garbage collection schemes into their SSD firmware which actively seek out and remove the garbage data. OCZ, in combination with Indilinx, is poised to release new firmware for their entire line-up of Vertex Series SSDs that performs active garbage collection while the drives are idle, in order to restore performance to like-new condition, even on a severely 'dirtied' drive."

Na das sieht doch pe-herfekt aus!

I have been working closely with OCZ on this new firmware and wanted to clear things up a bit. This new firmware *does not*, *in any way at all*, remove or eliminate orphaned data, deleted files, or anything of the like. It does not reach into the partition $bitmap and figure out what clusters are unused (like newer Samsung firmwares). It does not even use Windows 7 TRIM to purge unused LBA remap table entries upon file deletions.
What it *does* do is re-arrange in-place data that was previously write-combined (i.e. by earlier small random writes taking place). If data was written to every LBA of the drive, then all files were subsequently deleted, all data would remain associated with those LBAs. This actually puts OCZ above most of the pack, because their algorithm restores performance without needing to reclaim unused flash blocks, and does so completely independent of the data / partition type used. This is particularly useful for those concerned with data recovery of deleted files, since the data is never purged or TRIMmed.
Slashdot-specific Translation: This firmware will enable an OCZ Vertex to maintain full speed (~160 MB/sec) sequential writes and good IOPS performance when used under Mac and Linux.
Hardware-nut Translation: This firmware will enable OCZ Vertex to maintain full performance when used in RAID configurations.
I'll have my full evaluation of this firmware up at PC Perspective later today. Once available, it will appear at this link:
