    Author says his system only used 35% of the 16 GB ram. He is obviously clueless about the huge Windows cache usage in RAM clearly shown.

      Ngan Tengyuen [ Reply ]

      “By default, Windows caches file data that is read from disks and written to disks. This implies that read operations read file data from an area in system memory known as the system file cache, rather than from the physical disk. Correspondingly, write operations write file data to the system file cache rather than to the disk, and this type of cache is referred to as a write-back cache. Caching is managed per file object.”

      source: https://learn.microsoft.com/en-us/windows/win32/fileio/file-caching?redirectedfrom=MSDN

      Windows Cache is written on disk, not in RAM. RAMDISK will transfer the cache + other data from disk to RAM. The 35% is correct.

    In 2020 nobody needs a RAM disk.. modern OS will do this itsself..

      Ngan Tengyuen [ Reply ]

      Depending on the OS, is it 32 bit or 64 bit. Letting the operating system cache the file into RAM is more effective however on a 32bit system there is more justification for its use, as the disk cache can’t use more than 2GB of RAM. This is where RAMDisk shows it true performance for 3D Rendering, Games, Large Computing and etc.

      Ram disk are a good to prevent ssd wear down by extensive writes using torrents and download folders, also for applications that writes a lot to the user folder like firefox or chrome.

    I suggest that you consider adding ERAM to this list. It works on Windows XP/NT/2000/7/10 (32 and 64-bit) and has a maximum limit of 4 GB on Windows 7/10 (until I fix the BSODs caused by using a disk that is larger than that after removing the limit). Its driver and source code can be found by going to https://github.com/Zero3K/ERAM.

      Ngan Tengyuen [ Reply ]

      The problem with GitHub is not everyone is a tech wizard, the need to compile the software is a big turn off for most. That is the reason why it was not added to the list. The list I compiled is meant for beginners.

      • Gravatar

        You don’t need to compile the software. Binaries are provided in the releases tab, for both 32-bit and 64-bit systems. Most systems (and those who are looking for RAMdisks) are using 64-bit systems with tons of RAM, so if you’re reading this comment, you might as well check out ERAM and download the 64-bit version from their GitHub.

    I have a server that ingests and writes many GB of data per day. This is hard on a data drive. So, instead of writing all this to a physical drive, we write it to a ramdisk. And it doesn’t matter if it goes down…we use the “latest” data of this immense stream, so it would repopulate anyway. I don’t see any downside to using a ramdisk. Super fast, and saves wear and tear on physical drives.

    RAMDisk (WinRamTech) is the fasted RAM Disk out there. I have done several tests over the years and WinRamTech RAMDisk consistently takes the top spot in terms of performance.

    For those that say you don’t need a RAM Disk with a modern OS, I disagree. The level of control you have with a RAM Disk vs. letting the OS guess what’s best for you is night and day. One of the biggest reasons (IMHO) to use a RAM Disk is to help prevent viruses. Most viruses use temp storage for some part of the attack, so if you point all your temp variables, temporary internet files, etc., to a RAM Disk, every time you boot, all of that is automatically deleted.

    Halla – 1) A RAM Disk is much faster than an SSD.
    2) RAM Disk software takes a portion of your RAM and presents it as a Drive to the OS, so it looks and acts just like any other hard drive you have in your systems, except way faster.
    3) Install RAMDisk (WinRamTech)
    4) They are 2 different things. More of both is good! ;-)

    If someone want have fast working Programms, he need a RAM-Disk and Sandboxie. You can transfer the Sandboxie Container to the RAM-Disk in the Sandboxie-Settings. Now you must except the files, which should work untouched (bookmarks / history / cookies /settings). Webbrowse becomes very quick. I myself have a slow N3530 Atom-CPU with HDD inside, but it works very very quick.

    Who uses 32-bit OS anymore today?? It’s all 64-bit by default. I see too much info about benefits of using invisible memory etc while almost nobody has that anymore because of the 64-bit OS. More and more users have 16GB RAM installed with a dedicated graphics card (so no shared memory either), 32GB RAM or more is also becoming more common.

    On both old and the newest 2021 systems RAM-disks are far superior in speed then the fastest possible SSD’s. You can read/write old spinning HDD’s all day long without degradation in lifespan and performance. But SSD’s are very prone to wear and tear, specially in writing. Having the Temp-folders on the SSD is not bad, but lifespan degrades quicker.

    With the nowadays larger amount of installed RAM it’s easy to use it as a regular drive too besides the Windows Temp-folders. When editing photo, audio and video you’re talking about large amounts of data. When used on a RAM disk it works so much more smoothly. And just save the final results to a HDD or SSD for pemanent storage.

    The best possible configuration is put Windows and all programs on your fastest SSD, games on another (fast) SSD if possible, leave personal data on a real solid HDD (never store personal data on the OS drive anyway), and use a RAM Disk for Temp-folders and temporary working space.

    Why isn’t a RAM disk created in Video Memory? Today’s video cards have so much 6x memory. I can’t find a reason why nor a program that creates a graphics card memory ram disk.

    So Primocache is what I use and purchased, works amazing. Makes your hard drives feel like SSD’s. The more system ram you have the better. What I am looking for is a software similar to PrimoCache that will use system memory to cache hard drive read/writes but that is free. Some of the software here is for RAM Disks (taking memory and creating an E drive that looks like a hard drive, not what I want). Does anyone know of similar software to PrimoCache that is free?

    I did recent 2023 test with Ramdisks listed here, whichever were free, and claimed to be “faster than the rest”. My results on AMD 3900x DDR4 3200MHz Windows 10 22H2 are:
    – not StarWind, they openly agree
    – not OSFMount, middling perf
    – Sofperfect RamDisk reigns fastest! (and was for many years!)
    but one newcomer beat it.
    It was UltraRamDisk Lite.
    It got 1400 on 4k 1T reads, while Softperfect got 1000. Just to give you the scale.

    Free version is limited to 2GB, which could be enough for you.
    Softperfect still has older version available for free, which supports 4GB RAM disk (or slightly less, due to bug). You can find it on MajorGeeks etc.
    Imdisk was my go to solution as it is free and supports ISO mounting. Imdisk is the slowest RAMDisk – I tested their latest ImTools package. It is atrociously slow for RAMDisk duties. Avoid it.
    UltraRamDisk comes with ISO support too! I need 4 or even 8 GB RAM disk, and the only way to use it with UltraRamDisk is to buy their Pro version for $30.
