Scratch Disk a removable SSD?

Hi,
My Photoshop CS4 is now very slow
16gig of RAM plenty of HDD space + external hard drive
cache at 2 and 11 undo's
Tried to use SSD external removable but Photoshop does not see it in preferances
Can I make it see a removable drive or is this a safety feature?

You cannot use removable drives unless they use specific drivers that make them appear like intenral drives. It works as it is supposed to. It's probably beside the point, anyway. If your system is slow, it could have a million other cuases like the drives being fragmented or full of temp files. Some simple housekeeping may do more in the matter than buying expensive hardware...

  • Using SD Card or ExpressCard for Scratch Disk?

    On my old laptop, I know that the patch for Photoshop CS3 allowed using scratch disks on removable media. But on my new computer, I've updated all the software and cannot get these drives to show in the list of scratch disks. The expresscard and SD reader are both built-in to the computer so they are pretty darn fast.
    What trick do I have to perform to get these to appear and set them?
    Thanks!
    Kevin

    Do you have any mapped network drives? One annoyance (on Xp) is that card reader drive letter assignment appears to ignore drive letters assigned to mapped network drives and will always start assignment with next drive letter after your local fixed drives. If you un-map network drives your card reader drive will "magically" appear. (I get around this problem by assigning mapped drives starting at high drive letters.)

  • Hardware: SSD drives and scratch disks

    Hi,
    I am building a new system for Photoshop. Two quick questions:
    1. I note in Adobe's system reqs it says Photoshop cannot be installed on flash-based storage devices. Does this include SSDs? Is there a genuine problem here (i.e. if my application drive is an SSD the PS won't work)?
    2. I have not previously had a so-called "scratch" disk so I don't really know what it is or whether I need one, or more than one. What's the general advice here? - separate drive to the PS application drive? also separate to the Windows drive? How big? Will an SSD be a good choice for a scratch drive?
    Thanks in advance,
    Alastair

    G'day,
    In answer to your query SSDs work fine to install cs4 on bar the following I'm having.
    I've built a new system using ssds.and is working fine bar one problem
    Specs of the system is
    I7 920 cpu, Asus P6t se mb, 12gb ram, 128gb ssd, 64gb ssd, 4gb raid 1+0 array onboard, nvidia geforcegtx260. I use the 128gb ssd as the os and programs drive. The raid is the data drive. All works brilliantly except when I set the 64gb ssd as the scratch disk the following happens
    "Could not open a scratch file because the file is locked.  Use the 'Properties' command in the Windows Explorer to unlock the file."
    I hit OK and get this error -
    "Could not initialize Photoshop because the file is locked. Use the 'Properties' command in the Windows Explorer to unlock the file."
    Pressing ok then shuts the program and I need to reset cs4 prefernces and then it all works fine. OS is Win7 64 bit.
    Now I have just got to try and fix this problem Anyone got suggestions?
    Cheers

    Hmm, seems to have stopped doing this now after resetting the scratch to the ssd and then rebooting. All is now fine and wonderfully quick.

  • Photoshop CS6 scratch disk on hard drive or SSD?

    I've purchased a Windows 7 PC with 16 MB RAM, 2 terabytes and a 250 GB SSD. I'm going to load Photoshop on the SSD and the OS on the hard drive. Where should the scratch disk go?

    It's a bit tough to answer, as you have not described how you'll be using your system overall.  Are you going to be doing almost exclusively Photoshop work with it or are you looking for good all-around performance?
    What brand and model SSD is it that you have, specifically?  Generally speaking, if it's a modern model SSD with wear-leveling features in its internal controller, and with the other givens you mentioned, you will probably want to use the SSD for scratch, as SSD throughput is very high (hundreds of megabytes per second).  With SSD throughput levels, when Photoshop starts using its scratch space heavily the performance hit is much less severe than with an HDD.  There is also not nearly as much concern with an SSD about dedicating the drive to the task, as even if there are other activities on the drive the near-zero latency means that SSD supports multitasking much better.
    However, if you feel you'll never exceed 250GB for OS and applications (i.e., you're going to keep a relatively simple system), using the SSD for operating system and apps alike might be a better approach.  In that case there won't be enough space also for Photoshop scratch.
    Just keep in mind, when planning your "this goes here, that goes there" distribution that Windows and its apps are really most comfortable with EVERYTHING running on drive C:.  That's not to say it's a necessity, just that things tend to work more smoothly in that setup.  Given that, you might actually consider getting a second SSD and making a RAID 0 array for drive C: with plenty of space available.  That's the approach I took (in my case with four SSDs).

  • Additional SSD as Scratch Disk?

    I have the NEW MacPro which is fast & virtually flawless. I am a photoshop power user (VERY large files), and am thinking that an additional (external) SSD drive dedicated to use as a Photoshop Scratch drive, should be extremely fast, and save wear & tear on the internal drive. SSD's are more than twice as fast as a top Thunderbolt drive. And as a Scratch Disk the low capacity to cost won't be a factor.
    Opinions from other PShop power users? Anyone already doing this?
    Thanks!

    Yes, read up on the tips here:

  • I'm using PSCS6 on a 500GB SSD. Do I still reach a better performance by adding a scratch disk?

    Hi,
    OS X and PS are running on a 500GB SSD. Since I'm working with a MacBook Pro with 8GB RAM, I'm wondering if an external scratch disk would help to reach a better performance? The files, I'm working on, are usually between 300MB and 900MB.
    I appreciate your suggestions.
    Thanks,
    Daniel

    Photoshop PC version anyway seem to fill up the first scratch disk before allocating space from any other scratch disk.  So if you has sufficient free space on your scratch SSD  you don't need more scratch disk for Photoshop.   A raid 0 of ssd will stripe data across ssd devices and my improve performance.

  • SSD as capture scratch disk?

    Given that SSD disk aren't that big in size yet - does it work to have a SSD disk as capture scratch disk (DVCPRO50 and DVCPRO HD)?

    DVCPro50 and HD are relatively low load codecs. I can edit multiple streams of 720p24 easily from a good quality sata drive.
    It seems to me there is no real advantage for capture. It probably makes more sense to use one as the system drive.

  • What size for OS/apps SSD and scratch disk SSD ?

    Hi !
    I need a SSD for my OS with the full CS6 Cloud and few others apps (but no games, pictures, songs or other personnal stuff),
    that's mean between 70 and 80Gb. So I think I'll need only a 128Gb for that.
    I also need a scratch disk, so despite I prefer a fast and large disk like the Barracuda 3Tb, I read it will be better to take a SSD.
    My workstation is a 6x core, with 64Gb RAM, and 6x HDD for projects, render and footage (4K R3D and 1080p PRORES).
    My questions are :
    1) OS/apps SSD :
    Even if I only need 80Gb (or a few more like 90Gb max) of storage, do I need to take more than 128Gb ?
    Is it possible that the OS fill my disk with lots of temporary files ?
    And the same for Photoshop, Premiere, After Effects or others apps ?
    I know those apps will use the scratch disk, but maybe others temporary files will be write on this OS/apps drive ?
    2) scratch disk SSD :
    Like I said, I prefer larger drives, but as I understood, SSD will be better for preview and temp files,
    and actually I'm working with 4K R3D footages and 1080p PRORES.
    So do you think 128Gb will be enough for a scratch disk, to use with CS6, Blackmagic Resolve, and others 3D apps, like Maya ?
    Of course I can empty them regularly.............. but is it enough ? Or 256Gb, or higher will be better ?
    Or just a fast WD Velociraptor 1Tb or even a cheaper Barracuda 3Tb hard drive will be good enough ?
    Thanks guys.

    Thanks for your fast reply.
    But, I'm confused.... if the OS and the apps can fill my disk with lots of temp files, how a 128Gb can be enough ??
    Maybe you mean that those apps will fill the SSD with "hidden" files, but not reach the limit of 128Gb ?
    About Windows, I didn't knew I could make a scratch disk only for this temp files.
    Do I have to put the Windows temp files in the scratch disk also ?
    And you don't think a Velociraptor with 1Tb will be a good solution between the speed of a SSD and the size of a HDD ?
    My drives (alone or in RAID 0) are directly connected from the motherboard P9X79 PRO, trought the X79 chipset, and the Marvell chipset.
    But I read that the Marvell chipset has only 500Mb/s in total bandwitch divided between the 2 drives..... I'm not really sure....
    but even if it's true, I don't think the OS/apps will take a lot of bandwitch (except when I'll start an apps),
    and it will surelly let the full bandwitch for the scratch disk. Don't you think ?
    4 drives are connected to the X79 chipset :
    - 1x SATA 6Gb/s - Barracuda 3Tb (projects)
    - 1x SATA 6Gb/s - Barracuda 3Tb (renders)
    - 2x SATA 3Gb/s / RAID 0 - Barracuda 3Tb (footages)
    - 2x SATA 3Gb/s / RAID 0 - Barracuda 3Tb (footages)
    2 drives will be connected to the Marvell chipset :
    - 1x SATA 6Gb/s - SSD (OS/apps)
    - 1x SATA 6Gb/s - SSD or HDD (scratch disk for CS6 and other "video" apps)

  • If you have an SSD system drive, is a second dedicated scratch disk recommended?

    Looking to buy a new MacBook Pro which has one PCIe-based 512gb SSD system drive. Unlike earlier MacBook Pro models, there is no internal DVD drive to replace w. a second disk drive.
    I know that with HDD's a dedicated scratch disk that run's at least as fast as your application drive enhances performance of Photoshop. Is this also true with SSD's?  Thanks.

    Here's a suggestion (not aimed at anyone in particular, and I realize it may not be possible in all systems)...
    If you're going to set up a system to access a certain amount of storage interactively - and what I mean is storage that's used all the time in the normal operation of the computer - consider making one big system partition out of a RAID array of SSDs.
    With I/O operations averaging larger than the bare minimum (e.g., 4K bytes), RAID 0 effectively adds together the performance of the drives.  This is because there's effectively no seek time with an SSD.  It essentially randomly accesses stored data by address (it's quite complicated internally, but externally it works out that latency is almost negligible - literally measured as a few millionths of a second on a modern drive).
    So...
    Consider building your next system with multiple SSDs on task, making up an array of, say, a few terabytes.  This yields the following:
    Everything done by the system is done at the speed that's the sum of the drive speeds.  With a modern system using SATA III, that's essentially about half a gigabyte per second per drive.  Imagine throughput of more than a gigabyte a second - that's real.  Forget about dedicating drives to tasks - EVERYTHING gets the benefit of the entire RAID array speed.
    Since latency is virtually nonexistent, a great deal of multitasking can be done on the same volume without introducing any thrashing.  Photoshop can be writing to scratch, the system swapping like crazy, and you just keep working without notice.
    Everything's consolidated on one volume, which simplifies a lot of things (e.g., backup is simpler, applications install where they like on the C: volume).
    All the free space pools together, so what's available as transient storage for whatever you're doing at the time is maximized.  This tends to offset the extra cost of SSDs some.
    SSDs themselves are fairly new tech, and it's not been widely known that they RAID together EXTREMELY well.  They really do.
    People sometimes worry that using multiple drives to make up a single volume increases the chances for failure, but consider that SSDs are solid state, and so by nature have a good bit higher reliability (higher MTBF; often 2 million hours), and they don't generate nearly as much heat (they consume just a few watts).  Having SSDs in your system can actually increase the reliability of everything somewhat, because when everything is cooler it lasts longer.  Plus they don't make any vibration.
    This is not fantasy, I've done it.
    My current Dell workstation has a nearly 2 TB C: volume made up of four 480 GB SSDs.  My sustainable disk throughput is literally around 1.7 gigabytes per second (that's 15 times faster than a typical single hard drive).  I do also have some HDDs in the system, but they normally spend all day spun down.  They're for backup and very low access storage (e.g., downloads I've accumulated over time).
    I wait for NOTHING on this system.
    Oh, and it's been 100.0% reliable with this setup for 2-1/2 years now.  ZERO glitches.

  • Does anyone know if running Photoshop thru a external SSD (using firewire) as a scratch disk, on a imac early 2008- make photoshop any faster doing tasks?

    Has anyone tried this and if so, was there a noticable difference in photoshop doing its various tasks?  Again, its a imac early 2008, and I looking to use a firewire to attach a Solid State Drive to use as the scratch disk. I am maxed out a 6gb ram.
    Thanks

    CanadianBear
    KiltedTim's right of course. You seem to have adequate RAM.
    I would ask you if this sluggishness is NEW?  If so, what has changed that you can identify? Updates or upgrades? New software etc?
    What kind of tasks? Any operation on a big image is processor heavy, but you have the RAM so scratch disk is the right direction. What is your 'History' preference in PShop? Keep that as small as you can afford to. Save often. Keep as few images open as possible - each image has its own History. Save often.
    For scratch info on an image, choose that from the 'triangle' pop menu at the bottom of the document window. That seems a good way to tell if scratch disks are even at fault.

  • Scratch disks and RAM usage

    i would like to understand the relationship between scratch disks and RAM usage in Photoshop.
    While i was working on a fairly big psb file (2gb), photoshop kept prompting that I was out of memory, but in fact the utilization was only 75% (i had 16gbs total, photoshop was only using 7gb, and i allowed PS to use up to 14gb in total). when it says out of memory, it was actually my scratch disk at fault ( i only set 1 scratch disk, which was my 120gb SSD running out of space).
    any idea how I can optimize PS to use up all my RAM first before even touching my scratch disk? (short of using a RAMdisk, please).
    thanks!

    I am curious about this also. I just reinstalled W-7--have 11 G of physical memory--a ton of hard drive empty space also, and I have been wondering why PS_CC is so slow--since basically I have only put my Security and Browser in addition to Adobe back on the Dell XPS computer..... At least now it does show the downloading percentage (like .psd file) , but that must be what is happening.  I do think that some of these "frozen" screens I have been experiencing, was because the program was using scratch disk, instead of the Ram... I came up from CS-5, and can't describe it in detail, but just realize how slow PS-CC is in most everything.  Going back and see if reallocating will help...

  • Question about Photoshop scratch disk and specific setup

    Hi Folks
    Thanks for the help in advance.
    I'm a novice and need help finding a solution to a new PC Build. (Windows 7 Pro 64bit with Photoshop CS6)
    I only recently found out about having a scratch disk dedicated for photoshop (very novice i know ), and was wondering if a 120-128GB SSD would be enough? (Please bear in mind I can't fit large SSD raid configs to my budget, plus I live in New Zealand, so prices are higher for SSD at the moment). 
    I only edit single camera RAW files at a time around 25mb per file, with no large amount of layers and very rarely do large images i.e. Panorama etc.  I have searched the forums but could not find a concrete answer.
    My setup was originally meant for a HTPC (I don't intend to overclock), but I will also be using it for light photography projects. Specs below:
    CPU: Intel i7 3770
    Mobo: Asrock B75 Pro3-M (or Asus P8H77m Pro, depending on budget)
    16gb Ram (maybe bump up to 32gb later)
    120-128gb SSD for OS and apps
    120-128gb SSD scratch disk
    2 TB HDD for storage
    If anyone knows, the motherboards I've listed have 3x Sata3 ports, Asrock has one Intel chip and two Asmedia controlled Sata3 ports, while Asus has 2x Intel controlled and 1x Marvell controlled Sata3 port.  If I went with the Asrock, would it be okay to connect the OS/Apps SSD to the intel controlled sata3 port and have the scratch disk and storage HDD to the Asmedia sata3 ports?
    And one more novice question, when I begin to edit my images, is it best to transfer my photos from memory card to storage HDD then work from there? Or would it be quicker opening images direct from a USB 3.0 card reader / USB 3.0 external hard drive?
    Thanks again everyone, really appreciate it

    Just to clarify, if/when I get one 256gb SSD for my main C: drive, I can load the OS/Apps and store some data for the time being (until I get another SSD) and use the 2TB HDD for scratch disk only?
    Yes, that's what I meant.  You could try putting Photoshop scratch on C: at least temporarily, and watch your free space carefully.  If you don't work on big documents or set your history states to be very large, it might be workable.  But be careful.  The safe "set it and forget it" configuration is to make your HDD the one and only Photoshop scratch drive.
    When I do get around to getting the second 256gb, I will look at installing the two SSD's in RAID configuration.  If i were to do this, can I load the OS/Apps to the RAID SSD's as well as using them for scratch disks and have the 2TB HDD for storage? I hope that makes sense.
    Sounds about right; with 512GB on tap you should be able to run just about everything from C:, as long as you don't keep your entire photo library on there.  Realistically, on a big system that's got a lot of apps installed and has been used for some time, Windows and your apps may end up consuming 100 to 150 GB, so that would still leave you a lot of breathing room.
    Keep in mind that what you describe may require 3rd party re-partitioning software and/or backup and restoral, or a complete reinstallation of Windows and everything (usually the latter is what is recommended when moving up to a RAID system volume).
    By the way, SSDs stay in best working order if you overprovision - i.e., maintain a fair amount of free space.  The internal controllers need the free space to keep the data organized well and maintain top performance.

  • CS2 not recognizing external hard drive as a scratch disk

    I have an external hard drive that I want to use as a scratch disk but while I can navigate to have Photoshop open files from the drive, when I go to my prefs and try and select it as a scratch disk, it's not listed as an option - i.e. Photoshop only shows "start up" and "Mac Hard Drive" as choices. But when I go in that same dialogue box, and look for an additional plug-ins folder, I can navigate to the external drive. It's also doing the same thing for a thumb drive I have and two other external hard drives which mount fine.
    I have restarted the program, removed the Prefs file, and restarted the program again but it still doesn't see any of the external hard drives.
    Any ideas?

    mike,
    Most drives are not optimized for Mac as purchased. Unless marked otherwise, consider that every drive you acquire, whether a fast-spinning hard drive or USB flash drive comes formatted as FAT so it can be recognized and used by both Macs and Windows machines. Use Disk Utility and reformat it as HFS+ "Mac OS Extended (Journaled)".
    Just be aware that if you are reformatting your existing drives, you need to back up your data first or it'll be gone forever.

  • Save as Photoshop PDF Scratch disk locked?

    I searched  the forums, but apparently my issue only crops up when someone tries to launch PS. I can launch and do everything else just fine; however, I attempted to save as > PDF and received the scratch disk locked message. I can successfully save as PDF if I use the launch as admin option, but this seems odd since I can do everything else just fine without the need to do that.
    Here are my steps:
    Save as > Photoshop PDF
    Click OK on "The settings you choose in the Save Adobe PDF dialog can override your current settings...."
    I change [b]nothing[/b] in the Save Adobe PDF dialog. I simply click Save PDF.
    Select Yes for "Preserve Photoshop Editing Capabilities" in the prompt.
    Here is where I get the error message.
    "Could not open a scratch file because the file is locked, you do not have necessary access permissions, or another program is using the file. Use the 'Properties' command in the Windows Explorer to unlock the file."
    At this point, Photoshop does not crash or exit. It just simply will not save the file. This is the first time I've tried to save as  PDF, so it could just be a user error > replace user situation. :d
    I have tried the CTRL + Shift + Alt method of launching to wipe my preferences only to have the same result. My scratch disk is an internal drive used only as storage with 1.30 TB available.
    Photoshop CS6 Extended
    Windows 7 64bit
    User account is an admin, but I have never had a need to launch PS as an admin specifically.
    Thanks in advance.

    Checked my permissions on C:\Users\***\AppData\Roaming\Adobe\Adobe PDF\Settings and everything is fine.
    Taking that info and some google work I came across this: http://help.adobe.com/en_US/photoshop/cs/using/WS23B45D06-1977-4006-8BEB-2DBB08CA502Ea.htm l#WSA79FA899-BC95-401e-BD44-5B26BC31B369
    Apparently, there should be PDF settings files in C:\Users\***\AppData\Roaming\Adobe\Adobe PDF\Settings; however, my folder was empty, but the article above also says to move them from an 'Extras' folder located within ProgramData. Copied the settings over, tried again, same result.
    Am I supposed to have Acrobat installed for this to work properly? I don't have Acrobat, nor do I even use Reader (I use a different program for in-browser PDF).
    //edit
    Apparently it was in my settings on the PDF save dialog. I removed the settings that I moved over and tried again. This time I actually fiddled with the settings and used Smallest File Size instead of HQ Print, and that seemed to have worked. Messed with things some more, and narrowed it down to the Preserve Photoshop Editing Capabilities option. As long as that option is UN-checked, then everything works smoothly, including HQ quality.

  • Could not use the type tool because the scratch disks are full in Photoshop CS5.1?

    How do of get rid of the scratch disk error in photoshop? I'm using Photoshop CS5.1 extended and this error message apperars each time I try to do anything in Photoshop that message comes up. Anyone have any suggestions on how I can remove this error?

    What operating system are you using?
