The best free RAM Disk programs for Windows
The following guide provides you with an overview of the best free RAM Disk programs for devices running Microsoft's Windows operating system.
A RAM Disk, also called RAM Drive or RAMDisk, works in many regards just like a hard drive. The core difference is that it is a virtual hard drive that uses RAM for storage. With it come notable differences born out of that: a RAM Disk is faster than hard drives, and the storage space that it offers is only available during the session unless the software supports the saving and loading of disk images.
These traits make RAM Disks ideal for a lot of purposes. You may use it as fast, temporary storage for temporary data. Move the browser cache to the RAM Disk, and never have to worry again about it filling up valuable disk space (as it is only available during that session).
You may even install applications or games on the RAM Disk to benefit from faster loading times and less performance related issues while playing those games or using those apps. Another option is to move files that you want to process to the RAM Disk to speed that up.
The best free RAM Disk programs for Windows
Requirements are simple: the programs must be offered as a free version, and they must be compatible with at least Windows 7 or newer versions of Windows.
AMD Radeon RAMDisk
AMD Radeon RAMDisk is not limited to devices equipped with AMD Radeon hardware. Anyone can download and install the program, and use it to create a single RAM Disk with up to 4 Gigabytes of space. The limit is raised to 6 Gigabyte on systems with AMD Radeon Memory.
The program is compatible with all versions of Windows starting with Windows Vista, and supports the saving and loading of the RAM image on start or shut down for persistent storage.
The program is created by DataRAM, a company known for its RAM Disk products. The program displays an ad for the commercial versions of AMD Radeon RAMDisk on start.
Check out our full review of AMD Radeon RAMDisk here.
Dataram RAMDisk Software
The resembles to AMD Radeon RAMDisk is obvious. It is more limited than AMD's version, as you may only create RAM disks up to a size of 1023 Megabytes using it.
Changes may be saved on shutdown, and you may select to load the saved image on start. The program lacks features that AMD's version offers, such as selecting a drive letter for the disk.
Check out our review of Dataram RAMDisk Software here.
Gavotte RAMDisk
Gavotte RAMDisk supports the creation of a single RAMDisk on Windows machines -- XP or newer as well as Server 2003 and 2008 -- with no size limitation. The interface is basic but functional. Install and remove the RAM Disk, configure its size, drive letter and media type, and use the load or save image buttons for persistent storage.
The program has not been updated in a while though, and does not support Windows 8 or Windows 10 officially.
ImDisk Toolkit
One of the interesting features of ImDisk is that you may use it to create dynamic RAM Disks. Instead of specifying a size during setup, you may check the "allocate memory dynamically" option to have it changed on the fly.
The program does not limit the size of the RAM Disk, and you may use it to create multiple disks. It supports the loading and saving of images for persistent storage options.
ImDisk Toolkit offers more than just the creation of a RAM Disk. You may use the program to mount image files as well.
Read create a dynamic RAMDisk with IMDisk Toolkit for additional information.
OSFMount
Designed primarily to mount virtual disk images, OSFMount comes with capabilities to create RAM Disks as well.
Actually, it offers two options here. First, you may load a disk image file in RAM, or create an empty RAM drive instead.
OSFMount supports the creation of multiple RAM drives, and does not limit the size of them. You may select drive letters during setup as well, and may set them to read-only. Data can be saved to image files so that you can load it in the future again.
Softperfect RAM Disk
Softperfect RAM Disk is no longer available on the Softperfect website. You may still download it from portals such as Major Geeks though.
The program ticks all the right boxes. It does not limit the RAM that you may use to create RAM disks, and you may create as many as you have free drive letters for.
It supports the saving of images so that data persists across sessions, a lot of command line switches, file system selection for each RAM disk, and an option to launch programs when RAM disks load.
StarWind RAM Disk
StarWind requires you to create an account on the website before the download link of the company's RAM Disk software is sent to the email account you used to register the account.
The program may be used to create multiple RAM Disks that are not size limited. It offers basic functionality besides that however: you cannot assign drive letters to disks, and there is no option to save and load disk images as well.

Other RAM Disk programs
The following programs are not listed in the main section above for one reason or the other. They may still prove useful to you in some situations:
- Bond Disk -- The program supports a maximum size of 640 Megabyte. The main purpose of the program is however not the creation of a RAMdisk, but storage for files that hold valuable information. Additionally, it has last been updated in 2010. Read our review of Bond Disk here.
- Gizmo Drive -- Gizmo drive is part of Gizmo Central, and cannot be downloaded separately. The program's main purpose is the mounting of disk images or encrypted hard drive images. One of the features that it supports however is the creation of RAM drives. You may use it to create multiple RAMDisks that are not limited in size. Program has not been updated since 2011.
- VSuite Ramdisk Free Edition -- Last updated in 2010, the program is only available as a 32-bit version. It supports a size of up to 4 Gigabytes, and multiple RAMDisks. Also, supports the saving and loading of data on system boot and shut down.
Additional resources
The overview and description of each program is certainly helpful in determining the best suitable program for your use cases. I suggest you check out Raymond's RAM Disk Software benchmark to find out how many of these programs perform.

Closing Words
On a personal note, I have used SoftPerfect RAM Disk for the past years (the latest free version), and cannot be happier with it. It offers great functionality, and the downside that it is no longer maintained does not bother me as it works fine and without issues.
Now You: Do you use a RAM Disk on your system?
@Martin Brinkmann: with all due respect, this is now such a basic function, esp. for people reading your articles, that this article is like explaining to the readers how to calculate 1+1.
Yes, I have to agree with this. I can’t imagine that there are many spreadsheet users who are computer literate enough to even casually read ghacks, but don’t know how to use a SUM function.
@Klass Vaak & Herman Cost
Ever thought that people might google it so this artice might show up in the search results. So..no it’s not useless. I think it’s a good strategy explaining stuff even if it’s just basic things. Every day there is a new user on the internet searching for this kind of tutorial.
@Malte: you make a good point, in principle. Nevertheless, nowadays telling people how to do a sum calculation, the simplest of the simple, in a spreadsheet is like teaching grandma to suck eggs.
If say an elderly person would be sitting in front of a spreadsheet wondering how to sum a number of cells, that person is unlikely to look it up on internet, but would ask one of her/his children.
And in any case, Ghacks is not a spreadsheet tricks and tips site, so it would not show up high in the ranking in a Google search.
I`m an elderly person. 71.
My experience in computers spans 50 years, focused on Unix internals, advanced degrees.
I look to the internet for answers, since my children hate me and wouldnt tell me “jack”, even if they knew the answer.
I dont know how to “suck eggs in principle”, or anything else for that matter. I’m retired and not interested in learning. Some other guy learned “the theory of sucking things.”
Never needed spreadsheets, always too darn busy. Thanks for this info. Now I know how to sum two cells.
Everyone starts somewhere.
I am an elderly person and I can use sum, sumif, sumifs and so on. My kids come to me for knowledge on how to use excel and other programs ;)
But then, I was in IT my entire career before I retired :)
There are basic sites, and there are advanced sites. GHacks used to be more for people with technical knowledge. You can’t be everything to everyone though that seems to be the trend these days. Since it’s all about clicks and click bait the wider the topics the more you can remain “relevant”…
However, that mentality tends to alienate the more technical people. I find myself spending less time here every month. It won’t be long before I stop coming here altogether.
I have no mobile or wireless technology.
Anything google or apple is insidious to me. And that accounts now for most of the content here.
As to this article. Avast, and all of their products are untrustworthy. There has been much controversy and negativity regarding their products. I would think a reputable site would be more careful in what they publish… err, sorry, advertise.
@Klaas Vaak: In Martin’s defense, it’s the day after Christmas, and some eggnog recipes pack a *real wallop*. Maybe we’re lucky he could type at all. ;-) More seriously, I don’t use Calc super-often, I typically type in the =SUM() function manually, and I’d actually *forgotten* where the Σ button is located in Calc. (The last time I was a heavy spreadsheet user, it was in an older version of Excel and I’m pretty sure the Σ button was somewhere on one of the “regular” toolbars.) So, the article actually did have a small payoff for me. Plus, there might be other intermediate or advanced users of other types of programs (graphics, audio, video, word-processing) who have never used a spreadsheet in their lives. It’s kind of hard to imagine, I know, but it’s possible.
You were not born with the knowledge you have now. You once had to learn too.
So get down off your high horse, grow up and show a little respect for others who need details.
Overall LO has become a good SW, what prevents me to use it is:
https://wiki.documentfoundation.org/Development/Calc/XMLSource
“it will not store the information about the data source once the data is imported”
Until that functionality is implemented I’m forced to use M$ Office (2003).
@SpywareFan: an interesting alternative for M$ Office is Softmaker’s FreeOffice.
@Klaas Vaak
I have the Softmaker’s Free Office Suite in my computer – – and I LOVE IT!
intelligencia
In the FreeOffice manuals there is no reference to XML data mapping functions.
Another vote for Softmaker’s Free Office, a very nice alternative to MS Office.
Yes, I use functions in Calc: Average, Min and Max. I use the mouse to select the cells.
I don’t usually have to use Sum.
Thanks for the info, and could we have more tips for LibreOffice?
I find that the documentation does not keep up with the changes in LibreOffice.
Also, it is hard to find info in the help documentation.
Thanks Martin for all your great work you put in to make our live easier. Have a nice and healthy 2021.
To all those complaining about this being a simple ‘101’ function: it’s Martin’s blog, he can write a deep-dive review of Windows Calculator if he so wishes. Do you pay his salary or something?
@ShintoPlasm: yes, it is Martin’s blog, but it is a public blog with a comments section, which means he invites people to comment. And having been an avid reader for several years now, I am pretty sure Martin does not expect commenters to agree with him all the time.
You do not help him with agreeing with everything willy-nilly and “honouring” him with praise. Martin, like everyone else in the world, is not perfect, therefore he can only learn from constructive criticism.
Unfortunately you look at constructive criticism as a complaint. I do not agree with you on that and will keep making constructive criticism because I believe in keeping this website one of the best ones – refraining from constructive criticism won’t do that.
Absolutely. People could rather than leaving constructive criticism just stop visiting the site. How is that in the best interest of the site’s authors?
A new way to sum with the latest version is to place the cursor under the numbers to be summed, then press Alt-=, then ENTER.
The SUM function doesn’t work. It just keeps putting the same total no matter what figures I enter.
I would like to know how to make the sum function work. I know how it should work and it works in excel. But when I put the sum function in, it will not make changes when I edit and change the data, the total remains the same
Ditto, Marty. Everyone starts somewhere. Thanks.
Instead of being snarky, maybe you could be helpful. I’d like to add two numbers in a cell;
In Excel, it would be
=5+6
I try that in this piece of crap software, and get a message “Invalid value.”
I used Excel a lot when I was working. Retired now seven years. Excel was great, especially for macros. I now use LibreOffice, which works similarly but the macros are difficult in comparrison to Excel. I couldn’t find anything on macros for Free Office, which was disappointing, so I uninstalled it. I find Zoho to be the most similar to Excel but there you’re stuck with your spreadsheets in the cloud which I didn’t like.
Um… When was this article posted? The date says today (August 23, 2023), but I’m seeing comments from 3 years ago.
I was going to amuse myself and check out the comments for this Avast AV sponsored post since there were so many comments. I thought it funny since they have an article bashing the product in 2019.
What do I see when I go to the comments? Ghacks pulled an “Amazon” and replaced an article on Excel SUM functions with a sponsored post to make it look like a good article.
Anyone and everyone who even has a clue about tech knows that Avast is utter garbage and focuses on spying on you and spamming you with ads these days. Just check out the bad article from 2019 on this very site! If you run Windows 10/11, you already have better antivirus than Avast built-in to Windows.
@graham
surely more importantly is why an ad for dodgy anti-virus has the whole thread on office suites instead.. something in the db is messed up.
On a slight tangent, does foobar2000 have a built in lyrics plug in? I mostly used Linux and Deadbeef, the closest alternative to Foobar there has a very old(and kinda broke) plug in.

Magnificently,
I was able to clean up “all articles” by other authors on the Ghacks site.
It’s refreshing to be able to see only useful articles (instead of being buried among inferior articles) by clearing out the obtrusive articles.

What silly click bait article. Even the actual article is ridiculous.
“The launch of HarmonyOS for PC could pose a serious threat to Windows.”
Who cares what people in China use.
Don’t do drugs before working maybe.
What’s next? Look up the biggest Android fork in China and write pointless long article about it how it’ll take over Google’s Android.
HarmonyOS and Excel comments are mixed up.
HarmonyOS is not an open-source OS, only partially components.
P.S.
What is happening with these comments from other articles?
this is funny. it looks like the same base article, comments and all has been repurposed and edited or something for 3 (or more) different articles.
started off as something for some office suite… and then it was some antivirus thing.. and now it’s some iffy os.
wtf is that writer doing? no one reads or comments on the ad articles and he has to reuse old ones to make it look like it’s getting traction? (though it shows up as 0 comments on the homepage, so that can’t be it?)
“HarmonyOS does not have Google. Huawei’s HarmonyOS is a proprietary operating system..”
vs
“HarmonyOS is open-source, which means that it can be customized by developers and manufacturers.”
Both are quotes from the article. So which one is it, open source or proprietary?
Without windows-based videogames able to run, it’ll stay niche.
Huawei better put serious money into a harmonyOS port of Wine, DXVK or Proton if it wants its machine being more than web browsing thin clients.
I won’t trust a foreign OS.
Deeply foreign, I meant. In so many ways.
“I won’t trust a foreign OS.”
You trust Microsoft Windows, Google Android and Apple operating systems just because they are from businesses in your country ? Talk about blind nationalism.
Do not forget also that there is a world outside of USA and that for most of human beings, your favorite operating systems are also of a foreign origin, and as hostile towards them as they are towards yourself.
HAHAHAHA – did you really say “it could pose a serious threat to Microsoft’s Windows operating system”?
It won’t run programs or real games, so it will be useless.
I mean, there are some people who apparently love using tablets and phones for everything, but mostly are people who will barely do anything with their brain in life.
I mean, even if Photoshop, and others are available for iPad, do people think iPad is a threat for windows? not really, maybe for useless consumers who will just, like with a phone, be happy and move on, but not for professional industries which are the ones who matter the most, because are the ones who generate more revenue, since they buy the most expensive hardware and software.
Nothing consumer computing related really makes much money, unless it is data from users that get sold for AI or Ads.
Who knows where this comment is going to wind up. It’s in response to the article about Huawei’s HarmonyOS (HOS) operating system.
Two places in the article it says HOS is open-source. One place the article says HOS is proprietary. Uh, I’m pretty sure it can’t be both. Which is it? If there’s some fine distinction, somebody needs to explain it.
After all of these issues with Ghacks articles and misplaced postings, I’m reminded of this

@vanp,

By the way, if you use an RSS reader, you can track exactly where your comments are (I’m an iPad user, so I use “Feedly Classic”, but for Windows I prefer the desktop app “RSS Guard”).
RSS Guard: Feed reader which supports RSS/ATOM/JSON and many web-based feed services.

Regarding “Huawei’s HarmonyOS” you asked about, the developer has stated that it is planning to open source, however the actual situation has been shelved (no such movement).
HarmonyOS – Wikipedia

Therefore, it is “proprietary software”.
Moreover, both the company and its production base are in China. China, Russia, Israel, etc. are “Authoritarian state” and products and companies based in those countries are under state control, and privacy policies can become “famous and innocent.” Those products should be avoided.
Correction of sentence
Before correction: “famous and innocent.”
After correction: “nominal name only titular.”
owl, thanks again for the great info.
HarmonyOS doesn’t run Windows apps. It is no threat to Windows.
I agree.. i bet it cant even run wallpaper engine, it probably has the worst compatibility with software.
