Samsung's 64-GB Solid-State Drive 249

Anonymous Howard writes "Just a couple of weeks ago Sandisk introduced a 32-GB solid-state drive. Now Samsung has one-upped them, unveiling a 64-GB solid-state drive. They are expecting to begin shipping in the second quarter of this year. Samsung says the device can read 64 MB/s, write 45 MB/s, and uses just 0.5 W when operating (0.1 W when idle). In comparison, an 80-GB 1.8-inch hard drive reads at 15 MB/s, writes at 7 MB/s, and consumes 1.5 W when either operating or idle. No pricing yet."

      You don't need that speed for all your slews of videos and images, just put them ( and all data) on a regular disc, and use this for applications only. It'll last longer that way, anyways.

            They specify 10 years for flash memory to hold it's data, but in practice (e.g. not at the highest temperature or most extreme operating voltage) it is significantly longer. I don't know to what extent the hard drives work around bad sectors, but they probably do it for both flash drives and the traditional magnetic type.

              unless you're planning on treating it as WORM memory, flash has somewhat limited lifespan. the flash we're using at my collage for our integrated processing stuff is rated for 1 million write/erase cycles, but the datasheet doesn't even mention MTBF.

          It's not about the MTBF (the wear with age), yes you can almost indefinitely read data from you flash drive, when compared to harddrives, because there's no mechanical wear.


          The flash cells have a limited number of write cycles, which is very small compared to hard drives. If you write too much data on the same sector, the sector get very quickly broken.
          If you used a flash card for swap, it won't last long at all (because some sectors get constantly written over).

          To limit those damages, flash controllers use "wear level". That means that the small RISC controller that interface between the flash cells and the computer interface (ATA/CF, SD, USB, etc.) dynamically remaps the sectors so the wear caused by write cycles is distributed over several different sector.
          Let's say that an OS constatly writes data on the first couple of sectors. Instead of always writing on the first few cell, the controller remaps a different physical flash cell, to the logical disc sector seen by the OS.
          This works as a charm for flash media storing files likes used in digital cameras and such.

          But doesn't perform as well when used by an operating system.
          Windows XP is specially bad at this.
          Other OS - such as Linux or *BSD, that already have good support for running on slow read-only media (LiveCDs) for a long time, that don't need writing that much (except /var and /tmp, most of the rest of the installation can be read-only), and that support special file systems designed for lower wear (JFFS and such), may fare better : for example there are some Linux distribution that are tested for running from flash, like Damn Small Linux.

          • But doesn't perform as well when used by an operating system.

            Since flash doesn't have sectors that are faster than others; Thus, this is incorrect.

            Flash chips each have a read and write speed limit the more of them you have in parrelel the faster it can read/write. It's trivial to make the chips within a flash drive have JBOD(F) properties.

            This is one of the major advantages for me, disks that will be able to max out gigabit+ ethernet with increadible seek times, data redundancy, and massive througput.

            As disks get bigger it may become nescessary to have some space for a read/write buffer (normal HD's have ram for this) which will increase the life or need for higher MTBF sections, both of these properties are showing up in variations on flash.

            So if you have a flash disk with 1 Increadible MTBF chip, 1 super speed no storage sector (like ram), 1 massive storage space, and a bunch of standard flash you can have all the advantages of every kind of disk with the internal controller handling performance and wear leveling (not a trivial programming problem but one which we have a bunch of excellent solutions in place for).

            My personal problem with flash disks is that industry seems to be holding back development, trying to develop an upgrade cycle instead of realeasing a perfect solution.

            I can get a 1GB microsd flash card for $15 about 400-600(conservative) of them would fit into a 2.5 disk enclosure. With JBOD and wear leveling across the chips and I'm assuming it would be cheaper because you wouldn't need hundreds of cases/interfaces a 200GB drive with read/write speeds of 100-300 Gb a sec and seek time of
            Hmm, well maybe the price does need to come down but the other concerns about flash seem unjustified, write wear isn't a problem, it's not scary. losing all your data to a HD failure, now that's scary.

      Hard drive capacity growth has slowed the last years in notebooks, they just haven't been increasing in size that fast as in the early 00s. I think flash will surpass notebook harddrives in size within 2-3 years. As it is, 64GB is in the same magnitude of existing typical notebook drives now, just halfway down on the scale.

      The price may or not go down enough within that time period to kick out harddrives completely - in which case we'll just see hybrid drives take over.

      yes. a solid-state hard drive is exactly that - a normal HDD that uses a different mechanism for storing data. Usually its a pinning platter, this uses non-volatile memory chips. The interface and size are the same, so you just use it as you otherwise would.

      Personally, I think 64Gb is a bit much for me, I'd stick the OS and swap files on there - which come to about 10Gb on my current XP machine.

      Not totally certain, but I would guess so. Depending on how big the pagefile was, perhaps the drive does some intelligent load-balancing that would keep you from frying it too quickly, but it might be better to keep another drive around for that, or loading the machine up with enough RAM to keep it from swapping often.

      I used to know people who swore that, after adding RAM, the best thing you could do for speed was to add a small-but-fast SCSI hard drive and use it for nothing but your swapfile. I've never gone that route personally, because I've never thought it worth the expense, but I bet it would make for a pretty nice system. And I also suspect there have to be a lot of SCSI drives on the used market if you look.

              The numbers you used, approx 900/100, are also a special magic point on 32-bit CPUs under Linux. Above about 960MB, Linux uses "highmem" mode on x86, and that slows things down. A 32-bit x86 PC runs faster when you restrict it to 960MB instead of letting it use the full 1024MB.

              For those of you who wonder how a computer could run faster w/ a little swap in RAM instead of just using all the RAM, the answer is complicated. Mainly, all the VM algorithms assume the existance of swap, and so when they get backed into a corner, they expect to be able to dump a bunch of stuff overboard into swap. They only start making the really hard choices once swap fills up. If you take away swap, then you hit the "out of swap" condition much more readily.

              You might be thinking "ah, but it's all just a shell game! You'll still run out of swap at the same time, since your total memory is fixed!" Not true. The OS prioritizes disk buffers and other caches relative to the work it's doing and the RAM available to it. RAM dedicated to a RAM disk is not available for other purposes. Thus, a RAM-based swap partition dedicates some portion of RAM to only hold dirty program pages. No disk buffers, no network buffers, no inode information. Just dirty program pages. By forcing austerity on these other discretionary structures, you can compensate for the VM's inbuilt assumption it can just "dump things to swap", and that running out of swap occurs "almost never."

    Quality hard drives are fairly reliable. They can last 10 years or more and you can usually count on them to last their warranty period - 3-5 years - and then some.

    They also have error detection/correction, bad-sector remapping, and "I'm about to die" notification.

    At one time, solid-state devices were good for about a thousand writes for any given memory cell, a lot fewer than HDs.

    I worked with some industrial PCs back in 98, and they came equipped with solid state hard drives. They were around 120 MB, but the could load Win 98 in a few seconds. They solid state technology was important in that application, because it was highly resistant to shock and vibration. They could withstand like 80 g's of shock. Is there any reason that solid state cannot ultimately replace the current HD technology? It seems like a logic progression. Horses to Automobiles Propellers to Jets Vacuum Tubes

      For a long while I think you'll see more hybrids, and more use of a solid state drive to accelerate application loading, while platter based discs hold the mountains of "data".

      Other than application loading, there isn't too much use for these on personal PCs. They'd improve the hell out of database server performance, though.

      I think that the SSD is going to compete far sooner than most people realize. Looking at the numbers, we now see that laptops are almost outselling stationary computers, so people may actually turn to SSD as soon as 2.5 inchers at 200 GB come at competitive prices.

          Have to disagree with your thinking. I was obviously thinking of the most vital parts of the computer. I agree that the CD/DVD player could be included in that list, but a computer fan is only optional. You can get coolers with no moving parts too, you know.

          I am not sure if you're being sarcastic, but I was talking about the computer and not any mice, printers or whatever.

      But do you really need ssd in large volumes?
      No os partition + apps should require more than 10GB, and that gives you about 20GB+ of temp data to play with.

    Hm, based on the cheapest (without rebates) memory available at $8.50/GB, figure 20% markup between the manf and retailer, thats $6.8/GB.

    $435 for memory

    +10% for R&D
    +10% for manf (including controller, parts, etc)
    -10% for manf efficency when producing 64GB/run

    While 64 MB/s reads are definitely fast compared to =2.5" hard disks, can anyone explain what caps the access rate to 64 MB/s? I'd think the bus should be able to go way higher. Is flash memory inherently slow?

    If comparing these to 2.5" drives instead of 1.8" drives the advantages aren't as drastic.

    * 2.5" drives consume between 0.8W to 2.5W (ok, seeking eats a lot, but during sequential read or write, they consume similar amounts), almost no power consumption when they spin down.
    * 2.5" drives give 53MB/sec read and write.
    * 2.5" drives are very cheap and have triple the capacity.

    The solid state drives are still at an advantage, but it's not quite as large as compared to 1.8" drives.

  • Obviously, from a technical standpoint, flash drives should ALWAYS be faster than mechanical ones. MUCH, MUCH faster. That seek time, which is a fraction of the time that a hard disk takes, shows that the electronics can get to their data quicker. The catch is the electronics in convential flash disks have been designed to drive very small drives, and so there are bottlenecks that can make their transfer rates slower. However, in theory flash memory can be read in parallel and have a transfer rate of "t

    IANAL, but I have studied law and I have worked in the litigation field. I have read many letters that have had me wanting to ROFL, and this is in that category. But the best part is also the last bit:

      "From there, it should be a short trip to dismissal even if it means getting our clients to mediate Mr. Merchant's positive claims in the absence of an appropriate settlement."

    Translation: If you have read this far, you realize that you not only have no case, but that you are entirely out of your league because the standards of evidence in the court system where I have major influence, would procedurally bar you from even entering your case on the docket. Despite this, my client's claims against you are already demonstrated, and our claims will continue to have merit even after your case is dismissed with prejudice (and we have not offered to drop our case.)

    This letter is a masterpiece because it manages to hand the plaintiff his ass, in a rather respectful colleague-to-colleague way, while at the same time threatening a counterclaim that could end up with far greater damages than the initial claim!

    And the real beauty is that even though the RIAA seems to have withdrawn its claim, the damages from the malice might still hold, if they really want to push it.

    Who did they sue? Directors of a Silicon Valley bank? They should do some research before they pull the pin on the hand grenade!
