Mushkin Enhanced Ventura MKNUFDVU120GB 120GB USB 3.0 Solid State Drive

Blazing fast USB drive! Mushkin's 2 year warranty is for real as well. After 18 months of daily use my 120gb version of this drive became difficult to connect to a PC (wear on the copper connectors in the USB plug), however after a very brief phone call Mushkin is promptly sending a replacement. While it's on the way I went ahead and purchased the 240gb unit. I thought the 120gb was fast.....the 240gb is an absolute hot rod! This thing screams. File transfer rates times are impressive to say the least. I run a complete portable software suite from portableapps.com on this unit and all apps display exceptional performance. In my opinion the best USB drive on the market. Coupled with world class support, it's impossible to go wrong by choosing this device.

This obviously isn't a replacement for a normal SSD and is only first light uses. That's what I need, and I need fast speed in short busts. Cloned my Hiren rescue stick to it and it boots Acronis, Parted Magic, Ubuntu, and others extremely fast. It's IOPs make tasks quick and easy. Yep it gets hot but I don't use it extensively.

Damn this thing gets hot. My infrared thermometer read about 150F when I was done filling it with /dev/urandom prior to setting it up as an encrypted drive. You can't beat this capacity in this form factor with this speed...but the silicon DOES slow down at these temps - I don't remember the numbers from palimpsest, but I ran the palimpsest benchmark immediately after insertion and again after it got hot, and it was definitely significantly slower.I tend to be cynical. I am somewhat expecting this to fail. Enough that I will definitely be backing up whatever I put on here. The aluminum casing definitely acts as a heat sink; I wish they'd made the chevron grooves deeper, even if it made the casing thicker, as I think the increased surface area would dissipate heat better.Still, it's awesome for now, even at the hotter/slower speed. And 240GB? C'mon you can't beat that.

[Note: I own both a VisionTek 240GB device and a Mushkin Ventura 240GB device - they appear identical - They both exhibit OS corruptionafter being used for awhile.]This device works quickly as long as it is cool for sequential transfers. When it heats up, it drops to about 1/2 USB 2.0 speed. My intended use was to make a portable bootable O/S for recovery, etc, specifically Windows 10 Enterprise "To go" (Portable workspace). Initially it worked great for 3 or 4 weeks. I then started getting "hangs". There was also filesystem corruption on CHKDSK.. I reloaded the Windows OS image from a drivesnapshot (www.drivesnapshot.de) backup back to the USB drive.. Shortly started getting hangs and filesystem corruption again. This also happens with the 240GB VisionTek 240GB device, which I believe is the same device, different brand. The VisionTek also worked fine for 3 weeks or so running Windows 10 togo OS, but then it also starting getting hangs and filesystem corruption just like the Mushkin.My hunch is that there is a design bug in the firmware in the device controller. The device works flawlessly (my hunch) for awhile. Active regions in the filesystem (metadata, etc), get written very often, followed my immediate re-reads. This eventually results in the "wear leveling" firmware to get invoked, which maps out (or moves out) the "hot" sector with a fresh one, with a low write count. My guess is that while this operation is being performed the OS re-reads the sector while the wear-leveling is in progress, and receives bogus data, thus corrupting the filesystem and crashing the OS.It is easy to reproduce. I used both Windows 10 Enterprise TOGO X64. and Windows 10 PRO X64. If using Windows 10 PRO, one must install it first onto a regular (non USB) drive, and then image it over to the USB device. It will boot and run fine at first. Download and install Malwarebytes trial. Now startup full virus scans of the installed OS using both Malware bytes, and Windows Defender (part of Windows).Things work fine for six or seven passes. At this point some sectors may be ready for wear-leveling, and the hangs, and filesystem corruptions start. It takes an hour or two and is completely reproducible. After a filesystem corruption, I reload the USB with a fresh image of the same OS installation. (the filesystem hotspots are in the same place). Even after reloading the USB, it will be lucky to make it one pass through the virus scans before crashing/corrupting.However, when this device (after failing OS/corruption) is used for "normal" USB type operations (not running an OS), such as saving a backup image, it works fine at full speed. Backed up data to the USB device, comes back with good checksums.I opened a case with VisionTek customer service, and updated it a few times, requesting that they notify engineering of this. I have heard nothing back. I even gave them the procedures to demonstrate the corruption.If I did not need to use this device to run a bootable OS, I would give it four stars.. with the only other issue being thelarge slowdown when it heats up on large transfers. If you are only doing a few GB, then it would be 5 stars.Also, one can take a "regular" SATA SSD drive (e.g. a Samsung), put it in a USB 3.0 adapter, and plug that in to a USB port,and run the same OS tests above, and it will run fine for days with no corruption. The test machines I used were only USB 2.0,which might indicate that the wear-leveling operation has a wide window (milliseconds?)--ghg

I was quite excited when I purchased this drive, thinking a USB drive that can read and write at 400+ MB/s for less than $150 is a steal. When I got the drive however, I was quite disappointed.As a start, the read/write speed gets nowhere near the advertised 400MB/s. The speed I was getting was only about 220MB/s for read, and 120MB/s for write for actual applied performance (large file copying, not from any benchmarking software). At first, I thought to myself this speed is still decent for the capacity and for what I paid. However, I quickly realized how big of a mistake this purchase was after a few minutes of using the drive.The drive's case is made of thick and tough metal. They made it this way not to make it durable; it's solely for the sake of heat dissapation. The drive's casing still doesn't dissapte enough heat apparently, because after continuously copying large files for about 5 minutes or so, the drive gets warm to the point where it starts to throttle to a sustained speed of merely 20MB/s to prevent overheating. If you unplug the flash drive and quickly cool it off by gripping it in your hand or throwing it in the fridge, the speed will immediately jump back to the original 120MB/s sustained write. In a nutshell, unless you can somehow externally and actively cool this flash drive, it WILL throttle after a few minutes of intensive use.Both the not-as-advertised IO speed as well as the thermal throttling has been widly noted on a lot of other sites that sells this flash drive. Do not get this drive if you're planning to use it for IO intensive purposes. If you only wish to use the drive casually (such as for archiving or carrying documents and movies around), and you don't mind the inconsistent performance caused by heat after long periods of high IO, then I'd say go for it. Otherwise, there are better drives for the money that can perform much better and consistently.

Es una memoria grande y es rápida, el inconveniente es que se calienta mucho.

Muy buena velocidad de transferencia de datos pero con archivos grandes se calienta y baja la velocidad, pero buen precio.

Too heavy, breaks from its own weight.

Like a little hard drive! Really good!

Hab diesen USB Stick seit Mitte 2014 in Einsatz.Heisses Teil - im wahrsten Sinne des Wortes aber sonst Gold wert.Mehrere Notfall-Einsätze bei Freunde und defekten MBs sowie rMBPs und auch bei meinem late 2013 nMP. Exzellente Geschwindigkeit und ein gutes Dutzend Mal die einzige Lösung im Notfall.Derzeit an meinem rMBP mid 2017 funktioniert er über einen USB 3.0 / 3.1 Adapter hervorragend und liefert stabil ca. 415 MB/s (lesen und schreiben mit AJA System Test Lite gemessen)Da Apple derzeit keine vernünftigen GUI Festplatten-Tools zur Verfügung stellt und AFPS zuweilen Probleme bereitet ein guter Helfer in der Not.Meine eigenen MACs laufen prima aber selbst beim Verkauf meines HighEnd nMP musste ich auf den Stick zurück greifen um die SSD im Rechner von APFS zurück auf HFS+ zu bringen um eine frische Installation des Betriebssystems zu machen.Bootet einwandfrei und leistet hervorragende Dienste.Der Stick ist bei mir mit HFS+ formatiert und läuft problemlos an MACs jeglichen Alters mit USB 2.0 angefangen bis USB Typ-C.Kann nur jedem empfehlen so einen Nothelfer parat zu haben um im Zweifelsfalls den Rechner neu von extern zu starten.Kaum ein anderer USB Stick ist so schnell und vielfältig. Besten Dank an Mushkin für das Produkt und das hervorragende Preis/Leistungsverhältnis. Ich würde gerne öfter solche Berichte verfassen - die meisten Produkte sind leider bestenfalls Durchschnitt und da lohnt eine Empfehlung aus eiern Sicht nicht.
