What Disk Allocation Units should I use, RAID0 or JBOD

Hi, what Disk Allocation ubits should I use for drives.  The default in NTFS is 4k, is that OK or should I make them bigger?  If I use different drives to store different things should the different drives have different Allocation Units.
I have a USB3 enclosure with 2 TB drives in it.  Would it be better to use JBOD (i.e. pass throught) so I effectivly have 2 seperate drives I can put different stuff on or RAID0 whitch gives better performance in a single volume?

Thanks, was not sure if it should be in HW forum as it was conserning configuration of storage not chosing hardware.  Sorry about that.

  • What type of restore should I use?

    My computer is properly backed up using Time Machine. I created a partition using Bootcamp so I could install Windows (I haven't actually installed Windows yet). However, after testing Parallels, which is an amazing program!, I want to get rid of the partition and use Parallels instead.
    My understanding is that I have to wipe my hard drive to erase the partition. Assuming this is true, what version of restore should I use? I want the computer to be exactly as it is in the backup, except for the partition.

    When I go into the Partition tab, the diagram and text shows my HD as having 148.73 gigs of space (it appears in blue on top in the diagram) and "available space" being 49.5 gigs (it appears in white on the bottom).
    Once you deleted the Boot Camp partition, you now have only a single partition. The light-blue shading represents the data in the partition; the white are represents the rest ("available space").
    Is this how it should be? I clicked on both the blue area and the white area but that doesn't select them. There is no line between them for me to drag. Also, the "-" and "Options" buttons are grayed out.
    If there's only one partition on the disk, the whole diagram, containing both the blue shading and white area, covering the entire disk, should be outlined in medium blue. The "-" sign is grayed-out because there's only the one partition. If there were 2 or more, you could use it to delete one.
    If you wanted to make a second partition, you would click the plus sign. DU would then change the diagram, splitting the existing partition. Then you'd see a line between the two, which you could drag up or down, etc. The Options button is used when setting-up a new or erased drive "from scratch," to specify the *Partition Map Scheme* for the entire drive.
    Browse Disk Utility's help for a general idea of what it can do. (It's one of the few apps that has fairly comprehensive explanations and instructions.)
    I should mention that I installed Parallels so I could run Windows and Mac OS simultaneously (it is quite amazing!). Could it be that Parallels creates an unlabeled partition?
    I don't do Windoze, but it's my understanding that Parallels makes one huge OSX file that contains the entire Windows system, rather than the way Boot Camp uses a separate partition. I also understand that this huge file is automatically excluded from Time Machine, so it doesn't back the whole thing up every time anything is changed. You can check this via TM Preferences > Options.

    You'll need to be much more specific; there are 20 or 60 different kinds of high definition. Some require nothing, some require superfast RAID, some require specialized hardware support.

  • What XA JDBC driver should I use with Oracle 8i 8.1.6

    I need to use an XA JDBC driver for Oracle 8i 8.1.6. I am using the driver in
    a ConnectionPool in a TxDataSource for use by some entity beans using EJB 2.0.
    I'm running WebLogic Server 6.0 sp2, EJB 2.0, Java 2 SDK 1.3.1 Server VM, Solaris
    2.7, and Oracle 8i 8.1.6.
    I know of three different Oracle XA drivers: WebLogic jDriver for Oracle XA, Oracle
    OCI type 2 driver XA, and Oracle Thin tyoe 2 XA. Are there any other drivers
    that I can use for Oracle 8.1.6? Which driver and which version should I use?
    For example, can I use the Oracle 8.1.7 JDBC drivers with the Oracle 8.1.6 server,
    or would the Oracle 9i drivers work with the Oracle 8i server? Which drivers
    are faster, and which support more features? I assume that I should not use the
    type 4 driver since I am not using an applet, but I don't know if there are bugs
    in the OCI C library for Solaris or in the JDBC drivers that use it that prevent
    XA from woking. Which version of the Oracle C OCI library should I use if I use
    a type 2 driver?
    Thanks,

    Hi,
    I think you can't use the 8.1.6 thin driver for XA, you would have to
    use the OCI driver or 2PC-enable your datasource. AFAIK this has been
    changed for 8.1.7
    Check http://e-docs.bea.com/wls/docs61/////jta/thirdpartytx.html.

    Subject: Re: What XA JDBC driver should I use with Oracle 8i 8.1.6
    I've asked this question before. This is the reply from Joe
    Weinstein:
    For reliability and JDBC 2.0 compliance, I recommend the
    Oracle thin driver.
    If not that driver, you should verify that a type-2 driver
    actually does
    deliver better performance, but then I would not have a
    strong preference
    between their type-2 and ours. Theirs may be faster, and JDBC
    2.0 compliant.
    Both are succeptible to OCI bugs, some of which only they can
    fix, but we
    listen.

    Not quite. Downloading the current version of NeoOffice is definitely not free (downloading the previous version is). The developers of NeoOffice (the most Mac-like of the StarOffice descendants) make a distinction between the application itself (which is free) and downloading it, for which they require what they are pleased to call a "donation" (since it's mandatory, I would call it a fee).

  • What frame rate timeline should I use for 1080p 60fps premiere pro

    When using 1080p 60fps clips what sequence should I use when creating a timeline that would work the best for slow mo application?
    I read that you should use a 24 fps timeline but i'm not sure?
    Also I have a few 720 @ 120 fps, should I create a separate sequence for that and what kind of timeline should I use since cs5 only has 1080 @ 60fps option?

    24 is a good frame rate for most animations but some people like 30 and for the max stress on user systems and animation smoothness, use 60.

  • What type of repeater should I use with my new Airport Extreme?

    what type of repeater should I use with my new Airport Extreme? Thanks.

    If you want to repeat both bands of your dual band AirPort Extreme, another AirPort Extreme would meet these requirements.
    If you only need to extend one of the bands that the AriPort Extreme provides, then an Airport Express would do that nicely.

  • What RAID storage system should I use?

    To set the stage here. I'm somewhat of a newbie to the video industry. I've worked as a videographer for a non-profit for 5 years. At that job, we just skimped by on what we could afford, which wasn't much. I just started a new "professional level" job for a school district and have been given the keys to a fairly substantial budget to get whatever I need to do the job.
    I want to do right by them and not waste money, so I want my purchase decisions to be educated. I'm an intermediate computer user, but have never used raid configurations before, so please be kind. Also, we can really only purchase through a few vendors. B&H is where I'm getting all my other video equipment, so I'm only looking at options available there for my storage needs as well.
    Right now we record using Canon XA10 and XA20 model cameras. I'm hoping to upgrade to XF300's with this new budget, but still we're only talking MXF files, 1920x1080 at 50Mbps 4:2:2. So I'm not dealing with huge uncompressed footage.
    Still I record a fair amount of footage. In the first 2 months on the job I've accumulated about 460GB of raw video, and I don't expect demand to go down in the future.
    Right now, my idea is to purchase two Western Digital 12TB Raid Arrays in Raid 0.
    http://www.bhphotovideo.com/c/product/1053138-REG/wd_wdblwe0120jch_nesn_12tb_my_book_duo.h tml
    (I should note, I'm using a Windows 7 PC, so I only have access to USB 3.0, not Thunderbolt)
    The first raid array would be my scratch disk, the second would be used for manual backup at the end of every day. (Using a utility like SyncBack)
    Once my projects are complete, and I'm sure I won't need to access them, I'd like to move them off to a 3rd RAID array like this set up in Raid 5 for redundancy.
    http://www.bhphotovideo.com/c/product/1018063-REG/owc_other_world_computing_mercury_qx2_4_ by_hw.html#specOWCM3QX2K0GB
    This array would serve primarily as an archival unit, with only occasional transfers to it and use in only rare circumstances where I need access to several month old footage.
    Do you have any suggestions of a better system or workflow?
    Thanks so much!

  • What type of partition should I use? Range or Hash or ..?

    Hi,
    I am on Oracle 8.1.7.4 .
    I have a table with 10 million rows and looks like its a good candidate for partitioning.
    There is a varchar2 column and the data is evenly distributed on the string value. If I want to partition the table on that string value what type of partitioning can I use. How can I give the range, if I use range partition, on the string value ?
    Can/Should I use hash partitioning?
    I know that there is a list partitioning in O9i, but I am on 8i.
    Please help.

    Table volume, in itself, is not enough to warrant partitioning … hope you have some other reasons.
    <quote>
    … but would like to partition the table on the mentioned varchar2 column, so that queries would be efficiant.

    Since you don’t mention the actual query or class of queries, maybe it is worth mentioning that partitioning could speed up some queries but also can slow down a lot more other queries.

    There may be a case for partitioning … but you haven’t presented any reasonable justification for it … so, why bother?

  • What kind of motor should I use for lifting a heavy load?

    I'm working on an automation application in which I need to control a lifting mechanism with heavy load (about 120 lbs).  I will be getting constant temperature readings and based on that data I can determine the rate of change of the temperature.  If the temperature rate is too fast then I need to be able to slow down the motor, if it is too slow then I need to speed it up.  I'm looking for some support with choosing the right motor and hardware so that I have full speed control, while still being able to lift this heavy load, hold the load in a certain position, and then raise the load back to its original position.  I was considering a stepper motor for this due to its ability to brake so the load can stabilize.  Is this the right call or should I use a continuous servo?  Where can I get such a stepper that can handle this type of load and has software that interfaces with LabVIEW?  Would I be safe getting low-cost hardware for this application?  Any guidance would be sincerely appreciated.  Thanks.

    Thanks for your replies to this topic.  I just discovered the worm gear option yesterday while talking to a professor.  I think that is the route we are going to take because the DC motor won't be as expensive as a high-torque stepper or servo.  Also, I have three engineers that will be calculating the motor size based on gear reduction, spool size, cable length, and the load that we have to lift (which is about 120 lbs.).  If any of you would like to suggest a motor size, that would be great too.  I'm thinking something around 1HP should probably do it.  My goal is to stay cost-effective while making an easy apparatus.  I know that the worm gears may also be inefficient at times but it seems like the best solution for this application.  Not to mention it's not to hard for our mechanical engineers here to make the spool and bearings.  And I believe you can buy a DC motor that interfaces directly with a worm gear.  However, a follow up question is what computer hardware do I need to control the voltage of the motor so I have speed control?  Is this done through an RS232 board?  My output from the LabVIEW program will be voltages, from which device is that binary signal converted into physical voltage?  Thanks for your help so far.
