    So - today, I got a little curious with my SSD so I decided to run a few benchmarks.

    [​IMG]

    For some reason it seems to be stuck in SATA I mode despite my board supporting SATA II.

    All my current hard drives support SATA II the only thing that comes to mind is that im using a SATA DVD-RW which only supports SATA I transferates.

    Ive done what a few people did and installed intels rapid storage drivers but the results are still the same.

    Could the Sata DVD-Rw be forcing the system to run the hard drives at SATA I Speeds?

    if not what else could be the cause of the slow speeds?

    Just thought id add that the Drive is an OCZ Vertex 2E 2.5" with quotes R&W speeds of 285mb/s and 275mb/s on sata II but im not getting the same speeds

    Sorry I have nothing more insightful to say than did you try what you already asked yourself?

    set Crystal Disk to 0-Fill and see what you get

    I did not think you should use 0-fill for a SSD...I thought it was VERY bad for its longevity. I could be wrong though.

    That could be your problem. Try running AHCI only for your SSD and SATA for the rest.

    people on the OCZ forums said thats what your suppose to use or use ATTO program
     
    FreedomEclipse and JATownes say thanks.

    but why would Crystaldisk give such bad scores?

    ---

    And MM, I dont get the choice in the BIOS which drive to run AHCI on - its either IDE, RAID or AHCI on all of them.

    did you run CrystalDisk with 0-Fill?? also Crystal Disk is not very good to run actually. if your going to run it run it sparingly (VERY RARELY)

    Crystal Disk is basing the score off a different file system with 1-Fill. which is probalby what you have ti set to. with 0 fill its running off a more i dont know what to call it.... normal file system??

    no i didnt - someone said that it might be dangerous and the stress of thinking my system was 'locked' in Sata I mode really didnt help my nerves. and i have had enough dealing with RMAs recently and i dont want to add to that.

    How is your system locked in Sata I mode? you have Sata II motherboard dont you with updated bios??

    Yes CrystalDisk is a dangerous program to run frequently but if you do it like once to check to make sure its running right then your okay just dont run it ALL THE TIME! it rights critical data to the SSD which is why it can be dangerous

    yeah - but crystaldisk remember? Sata 1 is 150mb/s so i thought it was 'stuck' in that mode or something. ive even flashed my bios twice just to make sure that wasnt the problem. I was in a panic. i tested with crystal disk a fair few times just to make sure it wasnt a bad run but every time i saw 146mb/s.

    its sata II but i thought it was f**ked up and running in Sata 1 mode. not that it matters anymore as ATTO have proved it wrong. I think ive run crystaldisk enough times for one day lol

    Not sure if your affected by this or not but.....

    OCZ Technology Group Official Statement – Driving down the cost of SSDs

    As the industry transitions to the 2Xnm process, OCZ is notably the first to market with this
    technology that aggressively reduces the costs of our consumer‐grade SSDs. Most of our
    customers are aware that as the NAND flash technology process nodes are shrunk, the price of
    NAND comes down substantially. OCZ continues to focus on delivering the highest performance
    and highest reliability drives available at a lower price point…paving the way for SSDs to
    become more accessible to the complete range of consumers and to take the place of
    traditional mechanical hard drives over the next few years.

    Due to this natural transition to next generation NAND flash components, certain 2Xnm‐based
    SSD configurations may see a slight difference in the IDEMA (International Disk Drive and
    Equipment Materials Association) capacity, particularly lower density drives, due to the higher
    64 Gbit die density of 2Xnm flash solutions. This is due to the need to reserve additional space
    for the drives’ sophisticated performance and reliability features which provide real world
    benefits and are not offered by many other manufacturers. These features include RAID‐like
    data protection and recovery in the event of flash block malfunction, as well as advanced wearleveling
    to enhance the SSD’s endurance and lifespan. Due to the use of higher density chips,
    the quantity of blocks reserved for this functionality doubled as we reserve a single plane of
    flash for additional redundancy.

    Many users familiar with SSD technology understand that over‐provisioning flash is designed to
    increase, not only the life of the SSD, but the performance of the SSDs; however, OCZ is
    sensitive to issues particularly related to RAID arrays where capacity alignment becomes critical
    for optimal functionality. Even the smallest variance in size can create issues. In order to help
    resolve issues such as this and to clarify the situation we are disclosing (for vendor ordering
    purposes) the part number significance for our SSD capacity configurations. While we cannot
    guarantee (primarily due to price variance) that all of these parts are available at retailers, we
    as a company will extend our efforts to make these parts available throughout our Global
    channel. In addition, we’d like to point out to our customers that these products have always
    remained in production and are readily available directly from OCZ.

    We should note that this only effects smaller capacity drives with the “E” series of firmware.
    Non “E” drives have no capacity variance and higher capacity drives also have no variance.

    For those customers that have already purchased an “E” part and wish to move to a 32 Gbit die
    based drive solution, OCZ will offer a program in which customers can trade in their “E” drive
    and receive a credit towards the more expensive 32 Gbit die‐based drives. Customers only need
    to pay the difference in the raw NAND price and OCZ will ship the replacement drive once the
    original “E” drive is received. If you are interested in an exchange please contact an OCZ
    customer service representative and we will be happy to assist you.


    They've been dealing with angry customers since last week. Weird, I sent a PM to a mod last week about this and still haven't seen anything posted about it anywhere. Basically if you got a 25nm based drive instead of a 34nm you'll get less performance and capacity. You won't get the advertised speeds of the 34nm Vertex2 originals. Basically if you own a Vertex2 that came with Firmware 1.24 or newer when you got it, you got the lesser performing drive which they fully admit they hosed everyone on by not saying there was a difference. Anyways, here's the full link.....
