    Storage Review Site Update

    I am glad to hear that SR may be back alive soon enough. I'd be nice to see similar quality HDD reviews as SR used to have. Nowadays most sites only do "windows boot" and "HDBench/HDTach" reviews, which seem rather dull. I'll check back in a month. Best of luck

    Hitachi Travelstar 7K200

    I'd love to see that as well.

    DC++ fileshareing server

    I am curious how you plan to add files to your queues on the server, since I was looking for a similar option in the past, but couldn't eve find anything allowing me to add files without having to remote desktop into the machine.

    New System RAID 5/6 CARD help

    I would always get a separate system disk from the data storage. Even if your RAID-5 controller is very fast, a RAID-5 array is not well suited to host a pagefile, for example. Also, having a separate boot disk will make installing and recovering Windows (I assume that is what you will be running) easier, since you most likely will not need to load special drivers in order to access the boot disk.

    How do I best set up my five hard drives ?

    If you are using VMWare, it makes a lot of sense to have the virtual HDD on a fast HDD. It may be a good idea to not have a page file on the HDD that will be hosting your guest OSs. Note that using VMWare does not require you to partition your HDDs.

    Raid hype?

    Yes, you made the right choice.
  7. After finally moving my data files off my RAID array and onto my SLED, I had a PC and a RAID card to play around with. System setup: A64 3000+ (1.8GHz) 1 GB of RAM Asus A8N-E Promise SX4-M (64MB onboard cache, set to write-back) Samsung SP1614C (SATA) Maxtor disk - booting Software: WinXP SP2 nVidia driver 6.70 Promise driver 2.00.0.25 I ran a bunch of HDTach tests to see how my controller would hold up. It's in a regular PCI slot, no 64bit or 66MHz goodness. The results were partially straighforward, but some of them I cannot explain at all. So let's get started. The title links lead to the HDTach results if you want to compare. Maxtor Boot Drive 4 Disks in RAID-5 4 Disk RAID10 4 Disk RAID-0 3 Disk RAID-0 2-disk RAID-0 so far everything looks ok, doesn't it. Now for the weird part. I would appreciate some input on this: 2-Disk RAID-1 seeing that the CPU utilization was 'high' I re-ran it a little while later: still a weird outcome, huh. so let's see what a single disk (promise calls it JBOD) does: I have not tested the Samsung drives on the nvidia controller, but I think something is fishy. It surely cannot be that my drives are so crappy, can it?

    Let's see if Germany goes all the way. That would be a surprise.

    Impossible to install Raid0 on WinXP?!

    ps.: read page 157 of your manual, it explains how to make a driver disk.

    Does mechanical storage have a future?

    yes, mechanical storage will have a future, how long that will last is a different story.

    Impossible to install Raid0 on WinXP?!

    Let me verify that I understood you correctly: you have a working WinXP install. You created a RAID-0 array and loaded the driver onto the working windows install. Now the array does not show up in "My Computer". Have you checked disk management? certainly not. Provided that you have the correct driver, WinXP SP2 will support pretty much anything. If you are talking about a new windows install, you will need to hit F6 at the beginning of the install in order to have windows LOAD the driver. If nothing happens and you have a floppy with your "driver" in the drive then the driver is not in the correct format. There has to be a OEMSETUP.TXT on the floppy and a bunch of INF files.You may want to consult this: http://www.short-media.com/forum/showthread.php?t=32751 which is the top result on google, when searching for: "how to install windows on nforce raid"

    !Floppy Drive can't recognize disc!

    If you were a bit more verbose about your problem, it is likely that we'd be able to help you better. For example: Are you in windows, or are you booting off the floppy? If in windows, does it 'see' the floppy drive. Does the LED come on when you insert a floppy? Also, if you kepts your threads about your "I need help to create a RAID-0 array and install windows on it" problem together, it'd be easier for people to understand your problem.

    What's the fastest processor available?

    If, for example, you were profiling function invocation the profiler would overwrite the function calls with its own, which would be wrappers to your functions and keep track of the number of invocations. A similar technique would be used to compute the time that your programs spend in each function. I am assuming that fortran has some form of a function/ procedure call. By looking at the time that the executing program spends in each function, you'd be able to consider where you could look for improvements.

    What's the fastest processor available?

    Dual Opteron systems and the new AM2 chips have significantly more memory bandwidth than older chips. The soon-to-be-realeased conroe may be to your liking too, with more cache and possibly more memory b/w. that is surprising, considering that in most instances a dual-operton platform is considered to be superior to a notebook. from what I know about HDDs, they are much more efficient if you can commit larger amount of data at once (sequential write) rather than sub 512B chunks. there is, it's called perfmon, assuming that you are on windows AND using system calls for HDD access it should be able to help you. Alternatively, you could run it on a virtual machine just to analyze the process better. indeed that should not be a problem, but depending on the access pattern the "average" speed may have little reflection what speed the HDD needs to support at certain instances. well, if that is your goal, then you should take the person's advice and profile the program execution. While the profiling run will take longer, due to the overhead, it will tell you where your program is spending the time, which may be useful in determining not only the bottleneck, but will provide a starting point for future improvements as well.

    WD Settles drive capacity lawsuit

    the bad thing is that this Class Action Lawsuit was not even brought on by consumers, but by the attorneys themselves... Utter rubish. How on earth did they win it? Maybe I should sue the lawyer for increasing the price of my products? ps.: keep the political oppinions out of this. Bashing Americans or other peoples contributes little to the discussion.
