    Don't use the guide for changing default folder locations, I use this all the time for multi hdd/partitions.

    1. Once setup and at the desktop, don't bother doing any customisation, but start up Computer Management via Control Panel\System and Security\Administrative Tools.

    2. Local Users And Groups\Users, select Administrator and enable the account.

    3. Reboot.

    4. Logon as Administrator, no password, go into normal User Account management and delete the account created during setup and any and all files.

    5. Startup Regedit and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

    6. Change the ProfilesDirectory from %SystemDrive%\Users to for example D:\Users.

    7. Close down regedit and reboot.

    8. Logon as Administrator and create a user account with admin privileges.

    9. Logoff and logon using new account and let system create profile, which is now on your D: drive which of course now the default location for all your personal files.

    10. Start up Computer Management via Control Panel\System and Security\Administrative Tools.

    11. Local Users And Groups\Users, select Administrator and disable the account. Leaving this enabled is a big security risk !!!

    I have seen these words the other day~~~

    Based on the information Anand has given in his articles about Intel's technology, Diskeeper's "whitepaper" sounds like crap advertising by a company who's afraid their technology might be considered not only useless but detrimental to use with SSDs.

    I'm inclined to agree since Diskeeper's own results show a 4x write loss by just *one* "optimization" while Anand's article clearly suggests that the proper design (which he says Intel has accomplished) eliminates the need for Diskeeper's service.
    July 13, 2011 1:45:43 AM

    Things like automatic drive defragmentation with Vista does nothing for SSDs except to slow them down.

    Properly optimized, even low cost 2007 generation SSDs test out as equivalent to a 7200 rpm consumer grade drive, and typical SSDs made in 2008 or later tend to outperform mechanical hard drives.

    The tests done here have done nothing to "tweak" the OS to remove design hindrances to SSD performance, and thus, have no validity or technical merit.

    What's the current state of Raid0 and trim? I'm thinking of saving a little bit of money by buying two SATA II drives and putting them in RAID, but I don't want to lose trim support.
    a c 143 G Storage
    July 16, 2011 8:59:18 PM

    Currently, TRIM is still not supported by RAID between two SSD. It is supported with 1 - SSD (non-RAID) & 2 - HDD's in RAID. There is talk that Intel is working on a updated RST to give TRIM support in RAID. Until than, you would have to rely on the firmware's Garbage Collection to do the job.
    July 19, 2011 4:39:22 PM

    Is there a non sponsored site that keeps track of failure rates i.e. a Consumer Reports type deal? I'm currently in the market for an SSD, and one of my concerns are the failure rates on these things. I can look at benchmarks and product details, and of course there's no guarantee that any product will work right out of the box, but wading through the drives that are least likely to give issues is like a minefield.

    I understand that consumers may be partially to blame by not doing simple things like RTFM, but not all of the problems are with tech novices. What companies/drivers should I be looking at that are least likely to give me problems?
    July 19, 2011 5:04:44 PM

    I know that this is a difficult question to answer, but when I see a lot of people complaining on vendor sites, and at manufacturer forums how much of that should I disregard?

    Is it truly just people who don't know how to RTFM/ don't know that there's more to these than mechanical drives, or are there vendors and drivers that I need to avoid? A lot of the complaints seem to be against the newer Sandforce drivers, and that article looks like it's taking data from >13 months ago. I realize that this is a technology in its relative infancy in the consumer market, but besides pure speed would you suggest anything else to look for?

    Brilliant guide!!! Been looking for something simpler than the Win 7 method and this seems to be that something. Win 7 doesn't allow the original Admin account to be deleted so I had to create a second Admin with a different name then log in to that acccount and delete the original Admin account. Thanks :)

    the SSD and the HDD are not even related (except the i/o port (SATA III and AHCI/IDE)

    one is rotating memory. (imagine the head moving from track 0 to track max to access the swap file , slowly.....100 times more so.)

    the SSD is a EEPROM FLASH memory , made up of 960gig , Floating gate, EEPROM Flash transistors. (120GB SSD) the gates are charged or uncharged.
    reading the gates on Flash transistors has always been fast, but discharging them ,, in the early days , causes damage, the first EEPROM only lasted 100 writes and died.

    Windows prior to Vista and W7 do not protect the SSD at all. so dont run XP. (sure it runs, but dont run RIGHT !)
    But W7 still thrashes the HDD, or things like Antivirus, and csrss.exe(w7) ,etc.

    i use this prog to see this effect easy. free. (im sure there are better progs(apps)...)

    http://www.itsth.com/en/produkte/Whats-my-computer-doin...

    another great monitor program is famous, security task manager , that shows all processes, not blind like windows, task manager does. (i have a full license)

    The OS uses the HDD for many reasons , and some are to over come the horrible slowness of HDD . It is slow... (im on SSD as i type, and FF loads FAST !)
    Many of the killer processes are not even windows caused, AV/skype/FreeDNS tracker/Firefox / COMODO ,etc....
    Be sure to stop all processes you added to the system to see what windows really does by its lonesome.... do not assume.... (run msconfig)

    The What needs to be done in W7, (IMHO) is have an agent that allows me to set up a ram disk in memory that lets windows thrash away there.
    I have that now, for the swap page (pagefile.sys) see my sig. url for links to that free software .
    Put the internet cache there, and lots of other things, that are not needing permanent storage on SSD. (lots of ways to tune there are, do not give up)

    The windows OS , knows the HDD is slow and has , fast load drivers setup and other things (caches) to overcome HDD latencies. (gross it is)
    Using a SSD , many of those Ideas, are not valid, and in fact harmful to a SSD. 1,000,000 hits, is the spec. so avoid that. ( do you leave PC on when at sleep?)

    I am sure that soon, there will be vast improvement in this area, W8? and will have a wizard to let you decide. ( i can only hope, MS are listening? hah)
    Life or convenience? (eg: do you want to store history permanently here... or do you want max SSD life. it asks....)

    See the 18 steps for tuning on my page (i just have a link to the best page , not mine, on tuning....)
    my page is to cover , how to install SSD, the hard way. (adding easy way soon, besides, boot , install, take nap, run)
    a fresh install is easy, childs play if you mobo is not an antique and if it is , i have solution for that . (there are only 2 solutions)

    I was a system integrator. and certified ET, and am retired now. If you have questions, ask. I worked Intel for 6 years, testing , yes, memories.
    cheers

    or

    SSD's load many games faster. Once loaded most games run from memory so you do not get an FPS change in most cases.

    Some games that use heavy compression will not even be faster as the cpu is the limit in decompressing data.

    Many MMO(and some FPS) games load textures on the fly. If they do, SSDs will improve this because they are simply faster at getting to data so you may see less textures appearing in the near distance. This is all dependent on the game too. some will do this not matter what.

    The SSD+HDD is my method of choice as I can have anything that gets a boost from the SSD(Windows and most games[load times]) and files/desktop/documents/ect on the hard drive.

    I see no reason not to.

    I personally use an M4 256(well 2 of then because I wanted more space, they are NOT in raid.) + 2TB 5900 rpm drive with no issues.
    January 16, 2013 6:08:16 PM

    i was also thinking about doing the combination like you said, i would keep that HDD but i guess add

    30 GB Corsair Nova 2 SATA II 3.0Gb/s SSD - 270MB/s Read & 220MB/s Write (Single Drive) [-3]

    OR for 3 dollars more

    64GB SanDisk SATA III 6.0Gb/s SSD - 490 MB/s Read & 240 MB/s Write

    Are you going to have the 250 gigabyte Samsung + 30/64gigabyte SSD + HDD? You do not want to try to cache one SSD with another right? Its not a good idea and does not even work as far as I know. A smaller cheap scratch SSD may work for some users.

    Or are you looking at 30/64gigabyte + HDD. those are small so may have trouble getting much more then Windows on it. At least with the 64gigabyte one you will have some room to work. Turn off hibernate. Reduce the page file and system restore if you can as well.

    I do have Win8 on a 64gigabyte drive with some programs takes up about half the drive. You always want some free space on SSD's so they can perform better.

    February 22, 2013 5:33:34 PM

    Most if not all of the Win7 stuff works with 8.

    To be honest, Windows 7 and 8 take care of lots of stuff when they first run a WEI test anyway.

    So both 7 and 8 should not try to defrag ssds, but 8 will optimize(trim) the drive.

    Can you access system restore to try to undo this.

    Also note, I do not think that trick works for ALL versions of Windows.

    For instance, Windows 7 Home Premium does not even have Local Users And Groups\Users as far as I know that was limited to PRO and better.

    Another way around this is to just right click the users folder and more it with the location tab(works for most folders, but will NOT move appdata).

    This is not a perfect solution, but better for most newer users.


    May I also recommend starting a thread if you get stuck on this issue because we may start to fill this thread with too may support requests(and the title is not going to help people find your issue to help.).

    Just read the article regarding adding memory to increase SSD endurance and have this to say in response with a link to further explain.

    I see sooo many articles about reducing writes to an ssd to extend nand life. Unless the drive is in an extremely write intensive environment like a server, it is VERY UNLIKELY that you'll EVER 'use up' all your nand in today's ssds. Limiting writes is yester-years thinking...before all the new gen controllers with advanced wear leveling came to be. Here's an example of nand durability in the ssd endurance thread at Xterme Systems...scroll down till you see the most recent graph...and notice the Samsung 840 that endured over 6 PETABYTES of writes. This endurance testing is very hardcore...it's harded on ssds that any work environment.

    Would moving a user profile to a spinning disk slow logon to desktop time?
    a c 159 G Storage
    August 10, 2013 9:52:24 PM

    Not that I have noticed(on Win7. Win8 seems to have a slower desktop load in general), but I just moved the "users" folders(Desktop/pictures/documents/ect), so appdata is still on my SSD.

    Not that I have observed, though I have mainly worked with new setups and never moved an existing user profile from SSD to HDD on the same computer. User logon accesses your user profile information (hidden file in your user profile folder), loads your desktop icons, and loads your startup programs (Skype, Steam, Java Updater etc.).

    I firmly believe you are better off setting your entire user profile location to the mechanical disk. AppData would be one of the worst folders to leave on the SSD as that is where all your cookies and temporary internet files are stored. I have seen people who do a lot of web browsing add ~1 GB per month of data to that folder alone. Then you have to go through and clean it out with a program like CCleaner and you are cutting into your write/erase cycles on the SSD. The Desktop folder stores any data you place on your desktop and gets loaded when you log in, so if you are really concerned about login time to the point of splitting your user profiles folder between your SSD and HDD then the Desktop folder would be one you would want to put on the SSD.

    In a nutshell my advice would be to keep your entire user profile on your mechanical disk and save your SSD for only Windows and applications. If you want to split the user profile folder between the two drives then you can, but it is a lot cleaner and easier to manage if you don't.
