Review: Peace of mind should you lose your drive. - This enclosure is great. It keeps your information secured until you provide the key and provides a great peace of mind for protecting your data in the event that you lose your device. The device comes with USB C which is a welcomed addition compared to some of their other product offerings. The enclosure is a good value if you are looking to have an added peace of mind if you ever lose your drive. While it won't prevent someone else from being able to use your drive, It will prevent them from being able to access what you lost. Drive powers up and is readily available for pin entry in less than 5 seconds from when the device is powered up. I do find that most computers will post and begin booting before you even have the change to unlock the drive and mount the ISO. Also, some computers interrupt USB power during a soft reset which can sometimes make it complicated to get your ISO to mount. There is a function that keeps the password cashed for two minutes which aims to alleviate this but I found that entering bios or pressing the pause print screen/scroll lock on the keyboard sometimes will pause the power on self test. This gives me time to enter my pin and mount my ISO. Or likewise, i'll enter the bios setup utility (mount my ISO) and immediately exit it without saving changes and my device will be ready to boot from. Something to keep in mind but all in all, a very useful enclosure and it does make safeguarding my files convenient.
Review: An IT tech’s best friend. - Ever heard of Rufus? Windows app that makes it quick and easy to copy ISOs and images to a USB stick. Good for making Windows or Linux installers. Notice how you can only do one OS at a time? Ever heard of Ventoy? It’s a mini Linux bootloader that allows you to just drag and drop ISOs, VHDs, images, and etc to the usb drive, and boot from them in a list. So much more convenient, but then you have to hope Venroy both supports the ISO you’re trying to boot, AND hope it plays nice with your computer’s BIOS. Ventoy needs to be updated on the usb stick to ensure compatibility. Notice how that adds a failure point and more finagling? Here comes IODD with the easiest, yet most powerful, boot tool ever made. Slap a 2.5 inch drive in it (or perhaps an M.2 with a Sata adapter) and connect. The onboard screen will show you all the folders and files present. Select an ISO, VHD, image, or bin file, and it’ll put it in a virtual CD drive attached via USB. Boot from that natively, and you’re good to go! You can drag and drop any file just like Ventoy. Use ISOs alongside your documents and data. You can encrypt the drive with built in hardware acceleration. You can emulate floppy disks and internal AND external storage. You can set multiple users and add or remove access. No IT tech should go without their IODD.

## Questions & Answers

**Q: Can someone please run a crystaldiskmark and post the result please?**
A: Additionally for Developer/IT/Tech Savvy perspective:

I would measure IODD Mini's internal ISO emulation performance against real CD/DVD mechanical drive (assuming that I still has a reliable one laying around), it shows from my test results that the IODD Mini's internal ISO mounted volume is equivalent to (at minimum) 90x read performance vs real mechanical DVD/CD read performance (which is commonly rated as 4x 8x 16x 24x +/- the actual quality of actual DVD/CD media inserted), installing VM Server 2003 fresh setup & install start to finish barely took 6 minutes (assuming good hardware/spec system).

**Q: Hi, could i replace original ssd to a 2to ssd (sata m2b+m key). i understood for warranty will be void but it is physically possible?**
A: Yes you can, but the SSD Max power consumption may be lower than 2W.
Internal interface: M.2 NGFF 42mm
all warranties are invalidated (IODD MINI body and m.2 ssd)
thanks!

**Q: Will you release an nvme-based, usb type-c, 10gbps version?**
A: t will be some time before chipsets are cheap enough and good enough for all 3 of those features. Intel is still having trouble with PCIe 4.0 and only AMD has chipsets to handle the new generation of NVMe speeds that came with it. Newer, faster stuff is always coming out so you get the best you can at the time you need it and worry about the next gen later. As for the IODD Mini, I wish they had designed it to hold an M.2 2280 instead of the shorter M.2 2242 SSD's it holds, but other than that it's great. Sometime in the future another generation will be much faster and I will probably buy one of those when it's out. I've worn out older IODD devices and this is my 4th. The 2nd(2531) vanished and 3rd(another 2531) is still running but the Mini is so much better that I don't use it much anymore. You can buy a USB 3.0 to USB C cable or just an adapter and use it in a USB-C port. It's not as fast as the fastest USB-C devices you can buy but it's the fastest you can mount ISO's and/or VHD's and get use out of. It's so easy that I don't have to carry a bunch of USB drives and can get away with it and a single USB drive(in case I need to do something special like make a bootable USB but can't do it as a VHD or ISO. Once you have one and get all your stuff setup on it, you will wonder how you got anything done without it. I would love to see a faster one(or even larger capacity than 1Tb) but I don't think they would sell a bunch if it had to carry a $1000 price tag. They will come out with a new version when the numbers make sense as they need to actually sell them to stay in business. They tried to bring a version of the Mini to market several years ago but had to wait for the parts to get cheap enough that they could sell them to more than a couple people with deep pockets. There was little buyer interest when the price was much higher so don't expect a 10Gbps version until you see PCIe 4.0 NVMe showing up in more than just AMD motherboards. It may be an even longer wait as it still has to make sense to produce them at a price they will sell in decent volume.

**Q: When will Russia shipping be available?**
A: This is item will be sold world wide in Amazon global selling after November.

### ⭐⭐⭐⭐⭐ Works great! Had to disable secure boot for linux
*by C***S on August 11, 2023*

This device works great. So far I've installed windows 11 and Armbianx86, each OS on its own .vhd. Windows 11 vhd booted fine first try. Initially I couldn't get Armbianx86 to boot. Turns out I had to disable secure boot even though it was a UEFI version of Armbianx86. I have two partitions on the drive. Each partition is selectable and can boot from vhd or iso. Lots of possibilities with this device. As others have said, the documentation is TERRIBLE! I had to play around with setting the USB/internal drive settings many times to get what they do. The "mode" CD, Dual or Hard Drive are apparently set by file name. Go to the IODD download site and download the vhd and util tools stuff and read through it and try to figure out what is relevant. I created vhd using Windows disk manager and IODD vhd tool. Creating a vhd in Windows takes a while. The IODD tool creates a vhd almost instantly. Both work fine. This is a fun and useful device. $90 seems a bit overpriced.
