Necessary cookies are absolutely essential for the website to function properly. There are several apps that perform this function, but Tek Revue chose RAM Disk Creator from programmer Florian Bogner. You can create a RAM disk via the Terminal or with a third party app. If you’ve got good backups of your data and you’re willing to risk losing the contents of a RAM Disk in the event of a power failure, setting one up is easy and fun. However the big negative is that data stored in RAM is not persistent, meaning that it evaporates when the RAM loses power due to a reboot, shutdown, or power loss.ĭespite this drawback, TekRevue notes that there are still circumstances where you can greatly benefit from the speed of a RAM Disk, such as using it as a Photoshop scratch area, manipulating large video files, or testing complicated databases. RAM Disk benefits are still easy to understand since RAM operates at speeds far beyond current hard drive capability. Speedier than the poky hard drive, and stone quiet with the HDD spun down. I ran for a year or so in the mid-late ’90s on a PowerBook 5300 booted from a RAM disk. TekRevue notes that RAM Disks, as the name indicates, are logical storage volumes created using a computers memory (RAM) instead of a traditional hard drive or solid state drive.īack in the day, RAM disks were very popular, and support for creating them was a standard feature of the Classic Mac OS. Up to you how you would like to do this.How To Create A 4GB/S RAM Disk In Mac OS X I have chosen to copy and paste the first menu entry and simply change it's name and add the toram option as you can see in this photo. Navigate to /boot/grub and open up grub.cfg in gedit or your favourite editor. The mounting location should now appear at the bottom-right. Mount the 128MB partition of your USB by clicking the Play button when it is highlighted: To make the 'toram' permanent you will have to edit GRUB and add another entry to the boot options. To compare, here is my computer before and after using the 'toram' option: Booting will take a little longer as everything is being copied from the USB to memory. Add the word ' toram' right after the word ' boot=casper' and before ' quiet' then hit F10 or Ctrl+X to boot. The easiest way to test this out is when booting, hit the 'e' key to edit the boot options of Ubuntu. For this to work you will need around 4GB or more of memory to be sure you don't run out. A way around this is to have everything from the USB to be pushed into memory (RAM) which is a faster storage medium. This can be slow depending on the type of USB used. When running applications or any read operations, everything is run from the USB drive. In some cases you may have to change your BIOS from Legacy to UEFI or vice-versa if nothing is showing. When finished, you will be shown this screen: Any remaining will be normal USB storage: For the partition table, it is safe to go with GPT in most cases.Įnter how much of the remaining space should be used for persistence which sits on-top of the Ubuntu Live USB. If your computer only has secure boot then you must either turn it off or choose ISO file. Select the boot system and partition table which suits your needs. Select your USB from the next screen or select toggle USB-only show all drives if your USB is not showing, as it is being seen as a hard drive.įinally you will be brought to this screen which is the final confirmation before it wipes your drive: Next, click on the Live only selected option to toggle it to Persistent live selected mode: The first thing to do is select your source, use the file browser to select the Ubuntu ISO file. The program will then prompt for your password: Xubuntu have the repository Universe activated automatically.) If you run standard Ubuntu, you need an extra instruction to get the repository Universe. Open up terminal and run the following commands: There are a zillion guides how to get this up and running but usually you'll need another computer first if you got a dead hard drive. The first you want to do is boot up an existing 16.04 or later Live CD or installation. Mathieu Trudel-Lapierre Fri, 12:37:41 -0500Ĭomparison of Startup Disk Creator from 15.10 to 16.04: * Update UI and frontend code to drop the persistence widgets. Use an equivalent of dd to make an exact copy of the image to the device * Rework the whole imaging process for writing to devices: Usb-creator (0.3.0) xenial urgency=medium
