Should We Leave 10% of Disk Space Free??

I'm wondering if anyone knows whether we should be leaving the usual ten percent of drive space free on these SSDs in the iPads like we should with normal disk drives? I've been looking around to see if anyone is talking about this but can't find any discussion. I'm having a hard enough time not totally filling up my iPad so it would be tough to leave 10% available for system operations.
(for those that don't know, with the spinning platter style drives it's important to leave at least ten percent of your drive space free so the system can read/write to it. Completely filling up a disk drive can cause serious corruption. I'm just not sure how SSD works.)

You actually don't need to leave a fixed percentage free .... you just need some free space in general.
For example, if you buy a 40 Gb drive, you may want to leave 4 Gb free (I would personally only worry when I got down to about 500 Meg free). But if you bought a 720 Gb drive, no way should you leave 72 Gb free and unused for "system work".
In any case, I haven't heard anyone suggest that you need to treat SSD's any differently than mechanical drives.

  • Why doesn't my disk space free up after moving files to an external drive?

    I have a 750GB internal HD but film a lot of movies. To free up space, I have moved my iMovie clips off to a secondary hard drive, but I have not seen my free disk space free up on my Macbook pro. Why is this? I moved, not copied the files. They only show now on the external hard drive.
    I am looking at the free space in Finder > Get Info.
    I have easily moved a few hundred GB off to the new drive, but my internal HD still shows as over 500Gb used.
    Help!

  • Why does Tiger need so much disk space free?

    Is this a drawback to a Unix based OS? I know there are a number of bells and whistles to OSX.
    But it just seemed odd that with the old Mac OS I could go very low on disk space (yet have plenty of RAM free) and the mac would still boot up, and store files fine. I would not experiene slowdowns, nor other issues.
    My Performa 6360 had a 6GB hard drive and it ran OS 9.1. There were times when free disk space would go below a gig. Yes I had problems, but the problems were extension conflicts, web browser issues, and other issues with the OS, not necessarily because of disk space.
    Thanks,

    John,
    I found an authorized service center would charge me $80 to upgrade the hard drive of my Powerbook. An 100 GB laptop hard drive can be gotten for $150 from:
    http://eshop.macsales.com/item/Toshiba/MK1032GAX/
    and an 80 GB for $120:
    http://eshop.macsales.com/item/Seagate/ST98823A/
    So in reality we are only talking just over a couple hundred.
    Of course a cheaper option would be to burn to CD or DVD the data you don't use frequently at least twice and take it off your system. To find out where files are, I've made this FAQ:

  • How do I move my movies from iTunes to a portable drive in oder to free up disk space?

    I have less than 10% of disk space free and often receive a message that my strat up disk is nearly full.  I therefore want to free up space by moving my movies to a portable drive.  How?  I want to keep the movies on my iPad, though.

    Patti23 wrote:
    How do I move purchased movies from itunes to the icloud? 
    Delete them from the local computer.  Nothing gets moved.  If the content was purchased from iTunes it should be available for download again in the future.

    I want to keep them on the ipad they have been moved to.
    If the device is synced with iTunes on the computer and the content is deleted from iTunes it will also be removed from the device.
    Realistically, if you want to keep the content, keep it stored locally.  Purchase an external drive to store the content on.  Keep in mind that iOS devices are NOT backup devices, they merely mirror the content in the iTunes library on the computer.

  • I need to free up some disk space?

    I'm still not used to these apples so I don't know what to do. I bought a mac computer game for my child and it says "Requires at least 1 MB of free disk space" Free up some space on your local disk and then relaunch. I don't know where to go to see how much free disk space I currently have. Also I don't know what things I can safely removing to free up that space. Can anyone help me with this?
    I have itunes with several songs on it .. . .. I'm assuming thats taking up some of the space but I can't really take any songs off because then my IPOD is screwed. But what other things can you remove to free up space? Please help thanks!!

    Hi Jami320,
    Welcome to Apple Discussions
    As John said, you may want to move some of your files off your computer temporarily, until you can free up some space. You are in luck though, you already have one. You can use your iPod as a storage device, so you can put files on it as long as you have enabled disk use (Knowledge Base Document #61131 on Using your iPod as a Storage Drive).
    After you have freed up enough space; before you install the game, you may want to free up more space for future use.
    A great program to show you exactly what is on your computer is WhatSize.
    If you are going to use WhatSize to delete any files/programs/applications, please be careful and make sure you know exactly what you are deleting and if there are any repercussions. WhatSize will show you files that you would not normally see; they are referred to as "invisible files". These invisible files are hidden from the users view because they would clutter the desktop and they hold vital information that if corrupted or deleted may cause problems. Please make sure you know what you are doing!
    Have you deleted files that you don't use; like for my iBook, GarageBand. I use GarageBand on my iMac because it is much easier and faster, so I deleted it on my iBook. Have you tried the "erase install method"? The reason for doing this is because Mac OS X installs all the necessary fonts, languages, drivers, etc that people all over the world my need, by default. This tends to take up some room that you might want to get rid of (make sure first what you don't need and need). You erase and install your system software (Knowledge Base Document 301270 About Install Options w/ Mac OS X 10.4), and when installing, do a custom install. This way you can install the languages, drivers, and applications you want. The same technique can be done with iLife.
    I hope that helps,

    Get the new HD and an enclosure to put it into, then after formatting it to Mac OS Extended (Journaled) in GUID partition use either Carbon Copy Cloner or SuperDuper! to create a bootable clone of the internal HD. Then install the new HD into the computer. However rather than going through this excercise which is major surgery on an iMac I'd simply get external HD's to store large amounts of data. My iMac's internal HD is only 320GB however it staill has 219GB of free HD space because I store my large libraries on external HD's. Much easier and the performance doesn't suffer and I didn't run into any issues with breaking internal parts of making serious errors.

    That normally occurs because someone has turned on system protection for the partition. I can't see your image just yet. 
    Check to make sure that has not happened.
    The following image is how the system protection  window should look
    The following image is what you should see in your recovery partition if you have file options to show protected files. Anyhting else should not be there.

    Can You help me please?

    Sorry i can't find the bug!
    Of course is enough disk space free. The files are .bin, .img, .nrg and so on.
    Is it possible, that alle these postfixes wouldn't work? Or probably is it possible that ih make from the file zoom.nrg --> zoom.txt and then I copy it to the media folder on the mp3-player?

  • Cannot Back-Up Catalogue-Low Disk Space

    Elements 9. I get a low disk space-free up space message. I have had this happen enough to know that it is a problem with my "C" Drive, not my destination drive with 3TB. My "C" drive is 2TB and I have lots of media. I would like to know how I transfer all my media to an external drive and easily link the catalogue with the new drive without major problems. I prefer not to manually reconnect 25,000 files!!
    Thanks for your help!

    Thanks, but right now I can't do a back-up because I keep getting an error message that my drive is too full, and it must mean my C drive because my external has plenty of room.
    Do you get the message when in editor, in organizer or both ?
    Which operating system ? I suppose Windows : XP, Vista or Win 7 32 or 64bits ?
    From the explorer, when you right click on C: to show properties, how much free space is shown ?
    Now, when in the editor, look at the preferences/ performance. What is shown in the scratch disk box for C: ?
    Not sure I am able to guide you from there, but I am sure Windows experts can help you with that info.
    Yes, no problem about your second question : moving from within the organizer in folder view keeps the right drive/path correctly.
    Another question : what is PGT  ?

  • Hard Disk Space Usage

    I am at a trying to figure out how to retrieve some of my hard disk space as my Powerbook G4 with an 80 GB HD is now running painfully slow.I remember reading that Apple recommends keeping 20% of your disk space free for best performance and there is no doubt that since I dropped below 20 GB of free space the performance has been noticeably worse with many many more spinning rainbow balls. The Finder shows that I have 15.97 GB available.
    I have looked at the Finder and done a ⌘-I (Get Info) for each item listed.
    Desktop: 984 KB
    [My Home Folder]: 24.66 GB
    Applications: 4.41 GB
    Documents: 386.2 MB
    Movies: 3.96 GB
    Music: 13.14 GB
    Pictures: 5.04 GB
    Within this I looked at Library Info: 2.14 GB and Mail info: 1.38 GB. Clearly there is a lot of overlap since Movies, Music and Pictures are all under [My Home Folder]. I have only loaded about 30% of my CDs into iTunes so as you can imagine I am concerned that if I add more I'll have no space left. It seems silly to have an iPod that has a 60 GB capacity yet my hard disk clearly does not allow for that much music (I do not have any desire to use my iPod as a calendar or address book - it is a music device) and with the system software etc I know that there is a big imbalance.
    Any ideas? I've also noticed that mail has suddenly slowed down massively. I do not delete emails so that could be hoarding disk space I suppose.

    I only have 512mb ram and my computer works fine although it is always better to have more. An external hard drive such as Lacie is also a great bet - I just purchased a 300 GB drive and its the biz.
    I would suggest that you download whatsize from versiontracker - its free software that tell you exactly what you have on your computer in a table columned format - its brilliant and it lets you delete whatever you dont need within the software.

  • I deleted unwanted photos from my iPhoto library, emptied iPhoto trash & Finder trash... this did not free up disk space. please help!

    I deleted unwanted photos from my iPhoto library, emptied iPhoto trash & Finder trash... this did not free up disk space. please help!
    I have a 15-inch MacBook Pro (Late 2011) with OS X Mavericks 10.9.5
    Last week, my 500 GB Harddrive had 120 GB free space. I was feeling crumby and decided to make productive use of taking a day off to lounge around. I snuggled up with my laptop and dedicated hours to meticulously combing through my iPhoto Library. I had 13,000 pictures, and I got rid of those I didn't want. Having said "sayōnara" to about 6,500 pictures, I then emptied the iPhoto trash and the Finder trash. I took delight in the iconic paper crumpling sound of them vanishing into the digital void.
    Everything seemed perfect: the photos I loved were still there, the photos I loathed were gone, both trashes were beautifully empty. Having thrown away all of those awful, boring, and unflattering images of poorly light lunches and selfies gone wrong, my iPhoto library was half the size as before! I felt renewed, a little lighter, somehow more free, and I expected my hard drive to be a bit different to.
    I eagerly checked my storage stats. My heart sank to see that my 120 GB of free space, was still only 120 GB of free space. I restarted my MacBook; this did not help. I restarted it the next day; this also did not help. It's been 5 days and the hard drive still has 120 GB free space. This is not an emergency and it will probably be a good while before I clutter my laptop to the brim. Yet while I am glad I don't have to see cringeworthy pictures of my ex's unmentionables every time I'm showing off things I do want to remember, I'm still disappointed and now obsessed with solving this mystery.
    What is going on? I don't see them, so where are they hiding? How do I get the free space I should have earned from throwing away 1,000's of photos?!

    Thank you, Terence!
    Yes, I only emptied the trash when it was really full, once I waited until the trash cans contained 2,600 photos and then I emptied them - Oooops! In the future, I'll keep in mind your suggestion of deleting less than 100 photos at a time.
    I downloaded the iPhoto Library Manager and used it to rebuild my iPhoto. After a few hours of rebuilding, it generated a new copy of my iPhoto Library. This versions was nearly identical to the original (it was missing 5 photos and was therefore only 5 mb smaller). I guess my Library wasn't defective.
    I checked my storage stats, and interestingly, using iPhoto Library Manager did help with the problem that developed after I re-indexed my hard drive. My hard drive is able to properly recognize data categories again, instead of listing almost everything as "Other". Understandably, my free disk space changed from 120 GB to about 60 GB, because my hard drive now contained a second copy of my iPhoto Library as well as iPhoto Library Manager. It seemed like all I needed to do was throw these away, but when I emptied the trash, my problem was not solved. My Hard drive now looked like this:
    It appears to me that when I empty the trash, the things I throw away are just hanging around as backups instead of leaving! I went into System Preferences and turned of my time machine OFF. Now my hard drive looks likes this:
    The back ups of the iPhoto files, and the program which I deleted, are still on my hard drive some where but now they are listed as "Other" instead of "Backups". Do you know where they might be and how I can delete them for good?

  • My mac is runnug out of disk space. Do /i need to by external drives?  how much memory should i get

    My imac is running out of disk space. I download a lot of media from itunes. The HD movies and TV shows use so  much space. Should I switch to the cloud, clean up my memory or buy an external memory drive? If i get an external drive how much memory is suggesyed? 1TB, 2TB or more?

    Buy an external hard drive on which to save your media. The drive should be large enough to handle your entire iTunes Library plus how much you would anticipate adding to the library over the next few years. Then backup your existing library to the external drive: iTunes- Back up your iTunes library by copying to an external hard drive.
    After you have backed up the library to the external drive you can configure iTunes to use the library on the external drive in iTunes > Preferences > Advanced. Change the path to the external drive. Once you do that quit and relaunch iTunes. It should now be using the library on the external drive. Now you can delete the library on the internal hard drive to free up the space.

  • HELPDeleted user account with file vault on to free disk space, to no avail

    My saga is a long one. Quick telling: I am the administrator on my eMac, and was locked out of my desktop last spring when the disk became overly full. File vault was turned on, and I was told by my computer repair folks that since the desktop was encrypted, it could not be accessed. A sad situation, since I had not backed up the disk, and had years of family photos that were lost, not to mention iTunes, Quicken, and more.
    Since then I bought a back-up disk, and saved a copy of that desktop, just in case.
    My computer is overly full again, and today I decided to delete my old user account in order to free space. Of the 160G in this computer, 80% was associated with that user (that is, me). I deleted account via the System Preferences window and its Accounts window.
    I emptied the trash, and 'got info' on my hard drive, only to see that nothing had disappeared, memory-wise! I am still nearly full--only having 2G available, rather than the 130 or more that I had hoped to free up.m I restarted too.
    I went to Apple Support to find that one should turn off File Vault before deleting a user account. Unfortunately, this is impossible for me, since I can not/could not access the user account to turn it off.
    SO here is my question: is there a way to delete the files of a user account that had file vault turned on, but that is inaccessible? There is no deleted user file in my User folder, by the way.
    I am not suer what to do. Any help is appreciated.

    Thanks for your insights.
    The Tech Tool report happened after AppleJack, and never showed up before that. Restarting again just now, it showed up again.
    I had not emptied the trash, but did now, and the 'get info' on my hard drive still shows that I have used nearly all of my 160 GB.

    buy an external HD   1TB for $60
    NO notebook is a mass storage device, so dont try to turn it into one, it doesnt work that way.
    Unless youre using it every couple weeks, its static data and should be on an external HD
    In the case of a Macbook Air or Macbook Pro Retina with ‘limited’ storage on the SSD, this distinction becomes more important in that in an ever rapidly increasing file-size world, you keep vital large media files, pics, video, PDF collections, music off your SSD and archived on external storage, for sake of the necessary room for your system to have free space to operate, store future applications and general workspace.  You should never be put in the position of considering “deleting things” on your macbook SSD in order to ‘make space’.
    Professionals who create and import very large amounts of data have almost no change in the available space on their computers internal HD because they are constantly archiving data to arrays of external or networked HD.
    Or in the case of the consumer this means you keep folders for large imported or created data and you ritually offload and archive this data for safekeeping, not only to safeguard the data in case your macbook has a HD crash, or gets stolen, but importantly in keeping the ‘breathing room’ open for your computer to operate, expand, create files, add applications, for your APPS to create temp files, and for general operation.
