Create a RAM disk.

Overview

Note: iRamDisk is no longer under development, and it is no longer available for sale.

iRamDisk uses a part of your RAM to create a new volume shown as an ordinary drive that can be mounted and used independently in your Finder.

Since the access time to these datas is way more faster than usual (it can reach over 10 times of the normal speed for some configuration), it lets you do some things you would not be able to realize with a classic hard drive (along with relieving your internal one) such as getting a writing speed amazingly fast or moving the temporary files of some apps (Safari, Xcode, ...) over it when you want to optimize their own access time along with minimizing the impact of these files on your SSD.

However, do not forget that your computer does not have as much of RAM as your disk space and that you will lose the data placed on the new volume when you restart it. So, be careful when using it!

Why would I pay anything for a front end to some simple terminal commands? There's also free GUIs that will make you a RAM disk.

As a tribute for this great utility; I'll write a last review: If you have more than 8 or 16 Gb of RAM, chances are you rarely use it at full blast, so creating a small RAM disk with iRamDisk is a nice option that can be useful (search the Internet for typical uses...) iRamDisk is very easy to use, works perfectly (here on 10.11.6, but chances are that it runs as well on recent OSes). I have 8 Gb and never met a situation where my 1 Gb RAM disk could be an issue. I use it in combination with a RAM utility such as Memory Clean 3. Perfect!

The dev's site raises a security alert, except in Safari, where you can see it has turned into the most basic html page! I can even paste its content here: <html><br><a href="iRamDisk.zip">iRamDisk</a><br><a href="MailSatellite.zip">MailSatellite</a><br><a href="popCalendar.zip">popCalendar</a><br><a href="SpotFiles.zip">SpotFiles</a></html> I've downloaded iRamDisk to check if it's ok and while I haven't tried it, it looks a real app saying version 3.6.15... Does anybody have information about that?

Oh, I now see your message "End of story. You can download my apps for free."
So sad to hear that, but thank you for making your apps free, not many devs do this move when they stop their activity.
I wish you the best! :-)

I've tried a few ways of using ram disks and here is my best trial: Browsers' caches can use a large amount of disk space and have a lot of read-write tasks on your SSD — which in the end are not that useful... 1) I deleted the caches of Safari and Firefox in ~/Library/Cache 2) ran those apps and went to my most used websites, then quit the apps. 3) moved those folders to a 512 Mb ram disk 4) created the necessary symlinks in ~/Library/Caches So now, I've got my basic web caching working in RAM for the sites I use most and all the rest gets deleted at shut down (I think that caching a website where you go every six month, wearing out your SSD and wasting space is nigh on useless ;-) ) It's hard to tell if its faster or slower, as the bottleneck is generally the site itself, the server or your connection, so I haven't noticed a huge difference, but at least I'm saving a few gigs of space and may hopefully extend a bit my SSD's lifetime. Of course, this is not for basic users and everybody can live without. But I'm quite sure it may be useful for apps using cache a lot.

RAM disks are always a compromise as creating a RAM disk reduces the amount of memory available to applications and the operating system, and should their be a power interruption, everything in the RAM disk is usually lost. Instead I recommend saving the monies you are thinking about putting into a RAM disk and purchase an SSD (Solid State Disk Drive) instead for your computer. Prices have come down significantly and this purchase can effectively add years of life to your existing computer given the dramatic performance increase you obtain for your entire machine for all your tasks.

I agree, an external SSD would be a more stable alternative. And you wouldn't need a large one to equal the space you would dedicate RAM to. Still, either alternative is for power users. After all, who knows how to direct application caches to an alternative disk? As far as I know only Photoshop enables easy access to alternative disks for swap files.

A more useful application would be a GUI that enabled the management of selected application caches so that you could move them wherever you liked. In theory, of course, if you're using a laptop with an SSD there would be no significant advantage to a RAM disk anyway. Still, it would save read/write cycles to your internal SSD if you could direct cache files to an external drive. Now that would be worth $20. iRamDisk, not so much.

RE:B-Jefferson-Le-Blanc: I am not suggesting an external aux SSD. I am suggesting replacing you primary drive and running your machine from it. I just checked pricing and 512MB SSD's are less than $150, with some under $100. Many come with step by step instructions on how to install them. Even with an installation charge it still beats buying a new Mac for an performance upgrade.

@Jimw: OK. I misunderstood you. There was a time when upgrading the HD in a MacBook Pro was easy to do, and I've done just that. But upgrading the drive in an iMac is a tricky business best reserved for skilled hands. Meanwhile, Mac mini's have not been accessible for years. So perhaps a little clarity in your suggestion would have been helpful. But yes, if you are looking to upgrade performance on a Mac that can be upgraded, replacing a standard hard drive with an SSD will do the trick. And it would alleviate the need, supposing there is one, for a RAM disk.

That said, I just had another idea: Use an SD card, as most macs, until recently, have SD card slots. SD cards are even less expensive than SSDs and come in appropriate sizes for the kinds of things you would use a RAM disk for. This would be simpler than upgrading the hard drive, particularly on an iMac. Of course there is still the issue of the technical expertise necessary to direct application caches to an alternative drive. An app with a UI for that would be really useful.

Your last comment is a "Hot Button" for me. Apple is now making most of their products as closed systems, even the MacPro Desktop. In my opinion this policy makes the Mac significantly less attractive to prospective buyers. It my be a good tactic to immediately appease short term stockholders, but I believe it is a long term ticket for product failure. Professional users demand open systems. That is why I mentioned the professional installation option in my last reply.

@ Jimw: for the code to create a RAM disk, see https://www.tekrevue.com/tip/how-to-create-a-4gbs-ram-disk-in-mac-os-x/. It's pretty simple—and doesn't cost $20. Make a text clipping of the code and you can use it as easily as any app: just past it into Terminal.

This page also has benchmarks for an SSD compared to a RAM disk. Hint: the SSD is way slower.

@ Jimw: I agree with you that Apple is no longer serving its "pro" users very well. It's been over three years since the "new" Mac Pro came out and it hasn't received a single update in that time. However, you are mistaken about it being a closed system. It is in fact upgradeable, though components for it are not cheap. But then it's not a cheap computer. The shell pops right off providing easy access to everything. None of the main components are soldered in, as they are with most new Macs. But the Macbook Pros are hardly pro machines, closed and limited as they are, and with non-standard ports all around. With dongles or a Thunderbolt 3/USB-C Dock the cost of ownership is significantly increased. This whole thin-is-in thing is driving Apple down a dead-end street. What's more, once Microsoft's Surface Studio grabs some mind-share, even the iMac is going to look parochial.

As for Macs being hard, or impossible, to upgrade, from day one Steve Jobs frowned on user access to the Mac's internals. From time to time this barrier was lowered, particularly with the old Mac Pros. But this has been a tide that ebbed and flowed. Right now it's ebbed big time, no doubt thanks to their design guru Jony Ive, whose genius has faded, though Tim Cook hasn't noticed. But then he was never much more than a bookkeeper.

All this is, of course, way off topic. But for anyone who want's or needs to create a RAM disk, they are easy to make, though not so easy to use. Twenty dollars is too much to pay for a tool that only does the easy part.

My understanding is that the only things that can be upgraded by the average user after purchase in the MacPro "Coffee Can" is the RAM and the main 'hard drive' which is very expensive and proprietary(sole source-OWC). Unlike the 'Tower' machines here is no provision or room in the machine for any other cards or drives and that all such items must be external via Thunderbolt. That intrinsically excludes graphic cards and while Thunderbolt may be fast, it is not as fast as PCIe. An person with advanced hardware experience might also be able to upgrade the processor or have OWC do it for them at a significant cost. Given I do not have one of these machines I have no actual experience with them.
