32 GB Flash Storage Drive Announced

Audrius writes to tell us TG Daily is reporting that Samsung has just announced a new 32 GB Flash storage device. The aim of this new solid state disk (SSD) drive is to completely replace the traditional hard drives in many laptops on the market. Some of the advantages offered are the 1.8" form factor, read speeds more than twice that of a normal hard drive, and the promise of 95% less power use.

      Those are real hard drives, with flash memory interfaces. Good try though, and $6400 probably is too high anyway (4 GB CF flash cards can be found for approximately $300).

      Hmmm ... are you sure about that? They call it a Solid State Disk and say it's based on NAND Flash memory.

      The article certainly sounds like it's not using any spinning-platter/read-write heads technology -- that would not really be solid-state. That seems to be how it uses less energy and makes no noise.

      To me, this doesn't sound like a "hard drive", but a big whack of Flash memory which is treated like a hard-drive.

      The $6400 figure comes from the article:
      One of the few 32 GB Flash disks on the market is currently sold by Silicon Systems: The device comes in a PCMCIA form-factor and is priced around $6400.

      So, it's not like the posted pulled the number out of thin air.

      If it's got no moving parts, it's not what we would traditionally call a hard-drive.

      Flash memory that works has a much longer MTBF than hard drives, but each cell fails at approximately 10000 writes. HDDs fail randomly, Flash fails predictably, so this can be a good thing. Just make sure your filesystem rarely does or needs defragging, and does not log every read.

      On a flash drive it's not really important into how many segments a file is split or where they are located since there's no head spinning back and forth. So there's only a problem if your fs does defraging automatically, but it's quite easy to switch this off (at least for developers)
      Guess we have to reconsider some habits we've got accustomed to if traditional hds are replaced.
  4. What about the limited number of writes? by jay2003 · · Score: 4, Insightful

    I have the understanding that flash memory has a finite number of writes and that conventional filesystems with their update of metadata even on file read could essentially wear out a flash drive quickly if it was used as the main disk drive (as opposed to digital camera use or the like where access is comparably infrequent)

    1. Re:What about the limited number of writes? by kebes · · Score: 5, Informative

      This is certainly a valid worry. As I understand it, however, modern flash memories have more or less dealt with this problem, because:
      (1) The number of rewrites is now quite large (hundreds of thousands?)
      (2) The writing-to-disk software/hardware implements "load balancing." If you rewrite the same file 1000 times, it won't use the same exact block on the flash disk for each of those writes. Instead it will move from block to block with various writes/deletes/modify actions. This, coupled with some "slack" (the actual disk size is a little bit bigger than the "useable" disk size) allows for the wear to be distributed over the whole device.
      (3) The system uses conventional error-correction and flagging of bad blocks.

      As another poster pointed out, magnetic hard disks also have a limited number of rewrite cycles. But in practical terms we usually don't reach this limit. For critical applications I imagine you'd use a RAID of flash disks just like a RAID of magnetic drives.

      The nice thing about Flash is that after a cell has failed, it just becomes read-only. You can get around this quite easily in the OS by just marking the failed block as bad in your inode list. Over time, your flash drive will shrink in capacity. When it gets too small, you just copy it over to a new one and repeat the process.

    This technology has already been put to use in a commercial environment, and has given outstanding performance from what I've seen. The game EVE Online http://www.eve-online.com/ has already done this with their clustered servers and greatly reduced the lag. Keep in mind that this is a game where there is only a single universe (No shards or other servers) and they quite often push over 20,000 simultaneously logged in accounts at a time.

      I very much doubt they use flash based SSD's for performance enhancements.

      Most large scale systems that use SSD's to increase DB performance do so using DRAM (mainly) or SRAM based units with battery backup, RAM based RAID and controllers that dump the data to disk either on an ongoing basis or in the case of a power failure (using battery power to keep things up at least long enough to write a consistent snapshot to disk).

      The units are ridiculously expensive, but far faster than anything you'd manage to get with flash or harddisks (typically they're maxing out the controller/bus you connect to them via).

  17. flash wear-out by soundofthemoon · · Score: 4, Insightful

    Flash memory cells will indeed wear out after some number of writes. This number is typically pretty high, on the order of a million writes. For most file operations that will probably be a higher MTBF than a magnetic disk with moving parts. Any significant problem would be with hot spots, like VM backing store and file system tables. However you can level wear by using cells in a something like a round-robin fashion. Remember that contiguity isn't an issue with flash because there is no seek time waiting for the head to move. There will probably be some challenges in balancing wear leveling against optimizing file system and VM performance, but in the long run flash drives will likely be much faster and more reliable than magnetic disks.

      If you want to kill a flash drive compute the block size and write enough data to fill n-1 blocks then continuously update a small file with new data. you'll burn away that last block in a few weeks to a month

      Actually, this won't work. The wear levelling doesn't know if a block is 'full' or not, so it will just switch the contents of a pair of blocks. Your frequently-written file will move all over the flash chip(s), and so will your static files.
