Defrag Detects RAID-0 HDD as SSD

I originally posted this on the Microsoft Community Windows 8.1 forum.  A Microsoft Support Engineer responded by telling me it would be better suited in Microsoft TechNet forum.  So here I am.  Any help would be appreciated.
Anyway, I have Windows 8.1 Update 1 installed on a SSD drive.  I have a second SSD drive that is used for programs that benefit from high read rates.  Finally, I have four HDDs that are setup up as two RAID-0 arrays.  One is used for programs
while the other is used for storage.  Defrag detects the SSDs as SSDs, and the first RAID-0 array is detected as a HDD.  However, the second RAID-0 array is detected as a SSD.  As a result, I can't defrag the drive using the GUI utility.  (UPDATE: 
Running Defrag from the CMD line seems to work) 
The problematic array is identified as an HDD using Intel's SSD Toolbox and RST driver utility.  So I'm not sure why Windows thinks it is a SSD.  Rerunning WINSAT did not resolve the issue.  Is there a way to overide the Windows drive detection?

Hi
DarWun,
Disk Defragmenter uses the
Windows System Assessment Tool (WinSAT) to evaluate the performance of the device by getting the “random read disc score” of the device. The performance threshold was determined by some I/O heuristics
through WinSAT to best distinguish SSD from rotating hard disks. 
Here is a blog for reference:
Windows 7 Disk Defragmenter User Interface Overview
http://blogs.technet.com/b/filecab/archive/2009/11/25/windows-7-disk-defragmenter-user-interface-overview.aspx
There is a key in the registry, the Defragmenter will recognize the device as SSD when the value is above a specific valus.I recommend you check the values
of “randomreaddiskscore”.Here is the path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WinSAT
Here is a similar discussion(Pay attention to Tim`s response ):

  • Which is better 7200 RPM HDD or SSD for laptop upgrade to boost rendering times?

    This is my current setup
    RAM: 8GB
    Processor: Intel Core i7-3630QM
    GPU: Nvidia Geforce GT 635M - 2GB
    OS: Windows 8.1
    Storage: 1TB 5400 RPM HDD
    I am going to start editing raw footage in premiere pro. I would like to update my laptop to help with rendering times. Tommorow I will be installing 16GB of RAM. Which will be better for storage a 7200rpm HDD or and SDD drive? I am seeing conflicting views on the web. I figured that this will be the best place to ask, since I am upgrading primarily for this program. I appreciate the help.

    No clue what would be conflicting between the two. Both the internal operating speed of data handling and the i/o to the system over any sustained period of time are so vastly higher for a modern and large-ish SSD compared to any HDD that it is a total no-brainer. In fact, on the tweaker's page, they point out that for a really monster system, set up RAID's of multiple SSD's. Lacking that, RAID's of four or five linked fast LARGE HDD's which will be noticeably slower than the SSD option but typically better than single HDD's, even using one for each part of the process.
    For both the processing of data to present a view on the monitor during editing and during rendering, it's not the "burst" speed numbers that count ... it's the sustained long-term data transfer counts that matter. Which are different from what many think they are ...

    Turn the Mac on (or reboot it) and press command-option-R as soon as you hear the startup chime. Hold the keys down until you see a globe, then release. When the Recovery Menu appears you choose Disk Utility and format the SSD for use in a Mac (Erase>Set Format to MacOS Extended (Journaled), then exit Disk Utility and choose Install OSX
    You will need to be connected to the Internet and your Mac should detect your network and ask for a password automatically when Recovery Starts.

  • HP ENVY 17T - J100 I NED TO REPLACE THE MAIN HDD TO SSD

    I was just wanting to confirm that with the HP ENVY 17T J100 model can upgrade it's HDD to SSD? This model has the 1TB HDD. If I simply clone the HDD to an SSD of the same size.  will it work? Or is there more complex setup to get the raid working between SSD/SSD rather than SSD/HDD?
     also i try with 120 ssd and it didnt work. if i change the main 1 TB HDD to 1 tb SSd can i use the recovery disks to return all the windows as factory with the SSD or not and why if not
    Thanks for your time!

    Hi @sherifmadkour
    I understand you are looking at replacing your HDDs in your notebook with SSDs. I can help you with your question.
    Please see the following for your notebook family which shows the supported components.
    HP ENVY 17 Notebook PC HP ENVY TouchSmart m7 Notebook PC HP ENVY TouchSmart 17 Notebook PC Maintenan...
    You can find the drive list in the product description section,  and also under the Hard Drive list, in Component replacement procedures.
    Anything outside of that list would not have been tested with the other hardware, and so is unexplored territory. It is one of those things where if a device has different current requirements, it can put strain on the other hardware or an issue of driver compatibility.

  • Hdd to ssd??? is it posible on my gt70 ond???

    is this posible???

    Quote from: Ruudt on 06-August-12, 18:01:33
    Yes, that should be possible.
    Which GT70 do you have (HDD Raid (2 HDDs) or non Raid version (1 HDD))?
    First make sure you have made the MSI Recovery DVD set.
    If it's the non-raid:
    1.) Open the back remove the hdd and install the ssd in its place.
    2.) Use the MSI Recovery DVD set to recover your Windows installation.
         If you want to use the hdd as extra storage place the hdd in the second HDD drive bay.
    3.) Check if the bios is starting from SSD (instead of the HDD).
    If it's the HDD raid version (2HDDs) it's basically the same but you should turn off RAID in the bios, before step 2 and remove one of the HDDs.
    Or flash the non-RAID bios: http://www.msi.com/product/nb/GT70-0ND.html#/?div=BIOS
    i have HDD RAID, thank you 

  • RAID 0 array of SSDs: not a bad idea, but not easy

    I thought you all might find this interesting, and in any case, I'd enjoy hearing feedback as you might also audit these conclusions based on your own expertise with PC systems.
    I'm pushing technology to the furthest limits at all times, because I'm grinding through highly compressed 28 Mbps AVCHD 1080p footage while applying numerous layers of GPU-accelerated effects, onto multiple tracks and camera angles inside the Adobe Premiere Pro CS6 workflow.  We all know that one of the critical ingredients to surviving in that context is disk access speed (complementing CPU power, which for me is an Ivy Bridge 3770K overclocked to 4.4 GHz) -- and this is one area where a RAID 0 array of SSDs actually results in meaningful performance gains.  For people playing games, not so much.
    The dilemma, taking my Gigabyte GA-Z77X-UD5H motherboard as a typical example, was this:  I wanted my RAID 0 SSD array (two PNY XLR8's comprising half a gigabyte) to co-exist with my Vertex 3 SSD boot disk.  The typical Z77 motherboard only has two Intel SATA-III ports, and those ports are the only ones (to my knowledge) that offer native TRIM, while the supplementary Marvell SATA-III ports do not.  Since junk collection (of the kind that supplements any modern SSD's own internal junk collection) is more critical on the boot drive, and is almost useless on a mostly read-only drive, I didn't have the option to move my Vertex 3 SSD boot disk over to those Marvell SATA-III ports.  In the meantime, I did try out the RAID 0 SSD array on those Marvell SATA-III ports, which are supposed to provide a theoretical headroom of 1.2 GB/s (i.e., 600 MB/s x 2), but I got a stunningly offensive, ridiculous, laughable 350 MB/s or so read rate -- from a RAID 0 SSD array!  Those PNY XLR8's are rated at around 500 MB/s read speeds on their own!
    Bottom line, I felt that the optimal compromise was this:  move the boot SSD onto the Intel SATA-II ports, hitting up against the bottleneck of 300 MB/s (whereas the drive normally performed at around 500 MB/s on the SATA-III port).  Then, assign the RAID 0 array to the two native Intel SATA-III ports.  No joke, in that configuration, using ATTO Benchmark, I got over 1.2 GB/s read speeds.  That's a godsend for constantly pulling multiple compressed HD video source files (many of them over 1 gigabyte in size) into any complex video editing workflow.
    I haven't found conclusive proof, but I suspect that the motherboard's Marvell SATA-III controller is grabbing (for life) onto a singlular PCI-E x1 lane, leaving way less bandwidth than necessary to live up to even one single 600 MB/s SATA port spec, let alone the aggregate of several SATA-III ports.  Does that sound right?  And moreover, what moron would engineer things this way, calling a port SATA-III when it performs sub-SATA-II?
    I also suspect that this is fairly typical on today's best Ivy Bridge motherboards.  Thoughts?  We are all obviously trying to avoid the clutter of adding a dedicated RAID card, which would probably underperform in comparison to the native Intel controller anyway.

    Alex DeJesus wrote:
    So, is anything being done about the Marvel ports on newer motherboards?? Is it a firmware issue? I would like to put this behind me at some point. I find it hard to believe this topic hasn't come up before.
    I'd like to get two RAID 0 arrays on four SATA 6 GBs ports for storage and another RAID 0 of SSD for system and programs
    The only way to get more RAIDable 6Gb/s ports is to either get yourself a RAID card which in the case of your Z77 MB is not practical (it will cause your GPU x16 slot to operate at x8) or get the Asrock Z77 Extreme11 MB which has an on-board LSI SAS 2308 controller which interfaces to a PCIe 3.0 bus via a PCIe extender PLX 8747 bridge chip

  • I want to change my HDD to SSD for macbook pro 15 2010 need some help

    i want to change my HDD to SSD what will work with my macbook pro 2.66GHz (15-inch Unibody w/Intel Core i7) - April 2010 and do it will make my macbook pro low timp and do my macbook pro will be more faster ?

    Personally I am not a fan of SSDs because they are not cost effective for my personal requirements.  However I do recognize that the days of the disk are numbered, but I suspect that day is still a few years off.
    Crucial is a fine company and is one of the two I personally recommend for RAM (OWC being the other) so I suspect that would be a good choice to make.  They are a consumer responsive company.  Indeed the Amazon price is attractive but before you commit yourself, see if you can find test information and reviews on this product.
    I personally cannot give you first hand information on SSDs because I have none of my own.  But perhaps some one will read this post and chime in.
    Ciao.

  • Changing HDD to SSD, what are the options?

    hi, guys, new to the forum, I just bought a thinkpad x130e during an on sale event at one of the local retailer, pretty excited, since i like the rugged design.
    I am looking at an upgrade from 320G HDD to a 128G SSD... but i don't have any windows 7 installation disc handy, so what are the options for me to install the operating system (windows 7).
    I don't know if there is a way to transfer the whole system from HDD to SSD? will there be any trick to perform? or simply i just have to purchase new copy of windows?
    cos i noticed i do have a windows7 pro product key at the bottom of my thinkpad, i kinda don't want to waste the money.
    please help..
    Solved!
    Go to Solution.

    You don't need to purchase another copy of Win7. You will need
    1. SSD. This must be 7mm thick, not the more common 9.5mm thick.
    2. USB enclosure for your HDD,
    3. Software to "clone" the contents of your HDD to your SSD. Acronis True Image is a well-regarded package that does this. There are also some free utilities that can do this, however, I'm not familiar with them.
    Procedure:
    1. Move the HDD to the external enclosure.
    2. Put the SSD in the X130e.
    3. Reboot from the HDD. (You'll need to interrupt boot with Blue ThinkVantage button to specify.)
    4. Install Acronis (or equivalent.)
    5. Perform disk clone operation. You will need to tell the software how you want to resize partitions since you're going to a smaller disk.
    6. Reboot from SSD.

  • Going from hdd to ssd

    I would like to change a hdd to ssd on macbook pro (mid 2010). If I use time machine backup from old system on new ssd will it be copied with the old disk faults ? I would like to install fresh OS X on ssd, but at the same time I wish to keep aperture librery with all my pictures and iweb where I created my website.
    This are my priorities and the rest of data I can move to external hard drive and bring them one by one to new system on new ssd.
    Could you please, tell me how to do it and what is best solution ?

    A clone of a HDD will have loads of empty blocks, all those blocks would be written to the SSD...
    Incorrect.  Most backup programs don't do a block-for-block copy (though some have such an option on very restricted conditions).  They copy the files (like cp -rp).  So blank space on the source won't be the same blank space on the destination. 
    But serious question for a moment, do these Carbon Copy Clone drive 3rd party softwares have some kind of special function? Some people have crazy devotion to them and its peaked my interest as to why.
    If you want to go through the "exercise" of creating lauchagents or cron tasks for constructing and easily changing scheduling backups, more power to you.  I for one just want to schedule the stuff, possibly change the schedule if need be, and move on to more important things like doing the work that actually needs to be backed up!   If you don't believe in scheduling periodic backups, well, that's another story.
    Though, to be honest, I still question its usefulness when Disk utility does the same thing; select a hard disk ( "TOSHIBA MK2561GSYN Media" on my MacBook Pro), click "new image" and then click go. Then use restore in Disk Ulitity to restore the disk from the image - carbon copy goodness!
    So do most other people that do backups, i.e., creating a .dmg (what you get from DU's New Image) is not the way to do backups.  DU's Restore, maybe, but I've never used DU for backups.

  • Cloning Hdd to SSD boot drive and what happens with Music/Logic Plugins

    Hi, my computer is a mid-2012 Mac Pro 12 Core
    It's a great computer but I'm considering upgrading my main boot drive (WD Caviar Black 1TB HDD) to a 1tB Samsung EVO 840 SSD drive (I'm using a sonnet tempo PCI card to mount an SSD that holds audio at the moment and will add another SSD for the boot drive I'm referring to) so I just had a question - if I clone the HDD to the new SSD, what happens with things like licenses for my audio plugins, such as Native Instruments Komplete, programs by IKMultemedia. programs that use an ILOK such as Steven Slate Plugins and also, WAVES plugins?  Will this info all carry across to the new SSD drive or do you think I'll need to reauthorise some things?  I have all the serials etc so this shouldn't be an issue, but just wondered.
    Any help would be appreciated as it feels like quite a big step in that it's my main system drive!
    Thanks in advance
    Sam

    CCC is excellent. If it doesn't work then sure, just always have a safety net of your system that is untouched.
    Also, after a clean install, CLONE it!
    And then use Setup Assistant. Migration Assistant.
    Clone of the system can go on sparse disk images too so you don't have to partition (should have at least one though) and you can have clone from different stages and versions: 10.9.4, without Setup Assistant, migrated, full loaded with all your apps. Multiple versions.
    CCC is designed to make a working bootable copy of a system so you can move the system to another boot device like hdd and SSDs without the worry.
    But I think we were talking about a system that did not see a clean install of Mountain Lion or Mavericks so it is over due for one!

  • Upgrade HDD to SSD (Do i need to re-install?)

    I just bought an SSD (Samsung 470 series is the one thats best with MBP right?) and i want to replace it with the stock HDD that came with my 2011 MBP 13".
    What if i upgrade RAM from 4GB to 8GB and transfer from HDD to SSD by carbon copy cloner. Do i need to re-install Lion then?
    Is TRIM automatically enabled if i transfer from HDD to SSD?

    Upgrading the RAM is fine by itself. Just know you only have two slots, and thus need matching pairs of 4GB modules to increase the RAM from 4GB to 8GB. If you have $900, OtherWorld Computing has 16GB of RAM (two 8GB modules) for sale. (no compensation)
    Use the online Crucial checker and MacTracker to make sure your getting the correct specs of the RAM (and the amount of modules) before purchasing.
    What you need to do is use the free to use (donations accepted) Carbon Copy Cloner on the HDD while it's still in the machine, clone to a external powered drive and hold option to boot from it, test it out that it works.
    Then make the HDD to SSD switch and option boot from the clone again, format the SSD HFS+ Journaled and use CCC to clone it onto the SSD.
    OtherWorld Computing and iFixit has videos, pictures, instructions and tools needed.
    When you clone, it clones the OS X partition only, not both your OS X partition and the Lion Recovery Partition, which in your case is unnecessary to have if you have a "hold option" bootable clone. (should keep two at times)
    If you need to download Lion installer again, simply use MacAppStore and hold option and click on Purchases, either in Lion or Snow Leopard and then make a couple of " hold c" bootable DVD's from these instructions.
    http://www.eggfreckles.net/notes/burning-a-lion-boot-disc/
    These DVD's made from these instructions contain the full OS X Lion, not a Recovery Lion disk or the Lion Recovery Partition which Apple provides a download for and requires a lengthily Internet connection to download Lion before it's installed.
    Far as setting the TRIM, I don't know about that. Hopefully someone else will answer.
    If not ask Dave (Bmer) over here:
    http://macosg.com/
    He replaced his hard drive with a OCZ Vertex, the fastest SSD's on the planet and also his Superdrive with a 7,200 RPM 750GB drive for storage (note: you can't boot from a Lion/Snow/Windows DVD from a external optical drive) so he would know best what to do.
    Also OCZ just came out with a 480 gb or so very fast SSD, the Vertex 3 series, just as fast as the smaller SSD's but with more storage capacity, so that would be worth checking into. (smaller SSD's are faster, larger older ones are just a bit faster than a regular hard drive)
    Also check out your Mac model's SATA number using the fre MacTracker and System Profiler, this way you can by the right SSD for the price and know your bus speed limitation accessing the SSD.
    Good luck.

  • Will the new 2012 iMac support 2 hard drives (HDD and SSD) like the 2011 iMac?

    Will the new 2012 iMac support 2 hard drives (HDD and SSD) like the 2011 iMac?

    Well, I'm not sure how anything can fit into a 5 mm depth, so I can see why they've removed the CD drive -  there probably wouldn't be enough room for the laser, LOL. Can't imagine speakers, hard drive (of any flavor), logic board and so on and so forth. Fortunately, my iMac has Applecare through early 2015 so I'm set for a while; I may check out a Mini at that point - saw that it is configurable with a fusion drive, which would make it interesting for me.

    Hi, Christian:
    Yes, if you replace the hard drive or memory, the warranty will be voided as neither component is a DIY (do it yourself) project.
    Please see the service manual at the link below, chapter 6 for the authorized service center removal and replacement procedures for those components.
