Fast, Reliable, and Great Value!
SanDisk Ultra 128GB USB 3.0 Flash Drive is an excellent storage solution for everyday use. With plenty of space for photos, videos, documents, and more, the 128GB capacity easily handles large files without slowing down. Transfer speeds are impressive thanks to USB 3.0 — I experienced fast read/write performance, making backups and file transfers quick and hassle-free (much faster than older USB 2.0 drives). The slim, lightweight design makes it easy to carry in a pocket or on a keychain, and the sliding connector protects the plug without needing a cap. Durability feels solid, and it’s compatible with both laptops and desktops. Great option for students, professionals, and anyone who needs dependable portable storage at a fantastic price. Highly recommend if you want speed, capacity, and reliability in one compact USB drive!

Fast, Reliable, and Highly Durable – Excellent USB Drive
I recently purchased the SanDisk Ultra USB 3.0 256GB Flash Drive, and it has exceeded my expectations. With a huge 256GB capacity, it’s perfect for storing large files, videos, documents, and backups. The USB 3.0 interface delivers fast transfer speeds up to 130MB/s, which makes moving files quick and hassle-free. The build quality is solid and durable. The drive feels sturdy and compact, making it easy to carry around without worrying about damage. I also appreciate the added security features—password protection helps keep my data safe, and the RescuePro Recovery Software is a lifesaver in case files are accidentally deleted. It’s plug-and-play, so setup is straightforward, and it works seamlessly on Windows, Mac, and other devices. I’ve been using it daily for both work and personal files, and it hasn’t failed me once. Overall, the SanDisk Ultra USB 3.0 256GB is a reliable, fast, and durable storage solution. It’s perfect for professionals, students, or anyone needing a high-capacity, high-speed flash drive. I highly recommend it for anyone looking for a trustworthy USB memory stick that delivers both performance and security.

Another reasonable , reliable and nicely priced offering from Sandisk. With decent speeds too.
For me and USB flash drives , I find SanDisk to be the most reliable of brands , especially if you're sticking to the lower and mid range priced products. Sure they're usually not the fastest , but I have found after owning dozens of different USBs from different brands , that somehow Sandisk never fails me. For over a decade I have bought least a few dozen different Sandisk USB flash drives (From USB 1 - USB 3) and none of them have failed me. When I say failed , I mean none have them have stopped working or none of them have started to behave strangely. None of them have even had any short terms problems lost me any files either. For that , Sandisk have my trust. They are reliable products. but not necessarily the fastest. I have also flash disks from many other brands too. I have bought less from other brands and some of those brands , I have had a few of those drives fail or just have something wrong that makes them work strangely. Some of those flash drives have also gone bad temporarily at times and lose/corrupt data and files. Some of these brands are even regarded as trust worthy and well established. It's funny I bought way more Sandisk branded USB Flash drives and none of them caused problems or failed. I bought way less from the other brands and some of those brands had failures.(One brand in particular had a pretty high failure/fault rate) Enough about my thoughts on the brand , now onto the product itself. The Sandisk Ultra seem to be their most widely availible and affordable USB 3 flash drives they've been making in the past few years. It's their among cheapest USB 3 and the Ultra actually comes in other variations that share similar prices. (The rubber-like Ultra Trek and the Metal Ultra Flair) Today we'll be looking at the plastic one. Sandisk USB 3 Ultras , probably aren't that fast for most people going by USB 3 standards , but if you came from USB 2 , the difference in speed feels like quite a lot. The Ultra also tends to be quite a bit faster than a lot of other Flash drives within in the same price range from other brands too. But the Ultra tends to be a little bit more expensive than these slower flash drives. The main difference I can tell when comparing it to these slightly slower USB 3 flash drives from other brands that are similarly priced , is that there seems to be alot less buffering when writing. These other flash drives can sort of achieve faster write speeds than Ultra , but only in short bursts , and then they have to buffer down to USB 2 like speeds for a few seconds , then go back to fast burst , then slow buffer , fast burst , then slow buffer .... etc ... (Buy a really cheap Kingston or Integral drive for example to see this happen) I noticed that USB 3 Drives from Sandisk don't seem to do this. They seem to maintain a steady write speed instead . There's a lot less pausing (In most cases almost none) to buffer , so I think Sandisk uses much more efficient chips to process it all , even in their cheaper flash drives. Maintaining an overall steady slower write speeds , seems to be overall much faster , than a cheaper flash drive that can't maintain their fastest speeds for long , as those ones tend to pause for a few seconds to allow for buffering , which almost makes their short term speed advantage redundant. A good analogy is almost like the Tortoise and the hare. The Sandisks are slow and steady , keep on marching at a steady pace and finish earlier. While the other brands cannot maintain their fast speeds for long and have to take frequent pit stops to catch their breath and buffer , so somehow finish later than the tortoise. So overall the Sandisk Ultra is a fairly good speed for it's price when it comes to USB 3. It beats alot of similarly priced flash disks from other brands around the same price , due to a lot less buffering. The main bad things about the plastic version , is well it's plastic case. I've owned dozens of Sandisk over the years and despite me having my full trust in terms of reliability , it pains me to say they created tons of stinkers when it comes to physical designs of their outer shell/casing. Especially with their extensively Cruzer USB 2 range. They had tons of variations of the Cruzer line up in the USB 2 era , it's like they didn't know when to stop , trying to out do itself in making awkwardly shaped designs. I wish they would stop creating flash drives in unconventional shapes and just back to producing the simple classic small rectangular / oblong slider , they were using for many of their USB 1 flash disks and the first few iterations of their USB 2 flash disks too. Those were the best. The plastic Sandisk Ultra USB 3 , is one of it's worst designs in their history my opinion. Which is a huge shame , because it seems to be their most widely available / produced and distributed model of USB 3 . The main disapointment is the tail end of the platic portion of the body , that the drive resides in is made of a very thin plastic and looks like it would be very easy to break. I remember reading a review that it was compared to the plastic that you would probably find on a cheap free toy prize, that you would find in a box of cereal. I unfortunatly tend to agree with that observation. Sorry Sandisk you real cheaped out on this one. In combination that the type sliding style method they chose is also slightly awkward to use , you shouldn't be too surprised if the thin plastic will snap one day if you're not careful. Another thing I noticed , is that they skimped out in another area, with newer revisions of this model. I have actually bought quite a few of these plastic Sandisk USB 3 Ultra flash drives over the years , and I noticed in earlier versions of this product : there was a blue LED light that blinked during data reading/transfer. Later revisions of the same model , seemed to have removed/omitted this blue LED light , presumely to save on costs. Although I guess it was not essential , it's still helpful in a way to still have the LED light. I do hate it when products have features taken away , especially when it's done coverly without drawing attention. So that's another downer for me. Overall despite the physical short comings , the Sandisk Ultra is still a reliable USB 3 Flash drive on the inside , that won't cost you too much. Although I do recommend actually you go for the rubber-like Sandisk Ultra Trek which I think has a better form factor if you don't mind lids. The Trek feels more sturdy and seems to have the same speed performance as the plastic . I have yet to try the metal Ultra Flair , but I'd assume it's the same on the inside too , since it shares the same name : Ultra. Ultra Plastic , Ultra Flair and Ultra Trek all share a similar price range , especially if you buy direct from Amazon. It's all a matter of preference in the outer shell/case. Although, if you can spare another extra few pounds , you might want to try Sandisk Extreme Go . Which is has a pretty significant speed boost over the Ultra and with less buffering , without breaking bank too much. without setting foot into premium territory. but in the end the Sandisk Ultra is a good choice for an reliable, reasonable fast, lower end USB 3 Flash drive at an affordable price. I still recommend it .

Das SanDisk Ultra USB 3.0 Flash-Laufwerk mit 32 GB Speicherkapazität hat sich als zuverlässiger Begleiter für meine Daten erwiesen. Hier ist meine Bewertung: Dieses Flash-Laufwerk bietet nicht nur ausreichend Speicherplatz, sondern ist auch äußerst erschwinglich. Es ist eine großartige Option für diejenigen, die eine kostengünstige Möglichkeit suchen, Dateien zu speichern und zu übertragen. Die handliche Größe des Laufwerks macht es ideal für unterwegs. Es passt problemlos in die Tasche oder den Rucksack und ist daher perfekt für den Einsatz im Büro, in der Schule oder auf Reisen. Ein herausragendes Merkmal ist der einfahrbare USB-Stecker. Dieses Design schützt den Stecker vor Beschädigungen und sorgt dafür, dass er sicher und geschützt bleibt, wenn das Laufwerk nicht verwendet wird. Das gibt mir ein Gefühl der Sicherheit, dass meine Daten vor versehentlichen Schäden geschützt sind. Die USB 3.0-Technologie ermöglicht schnelle Datenübertragungsgeschwindigkeiten, was besonders praktisch ist, wenn ich größere Dateien wie Videos oder Fotos übertrage. Die Übertragungsgeschwindigkeiten sind deutlich schneller im Vergleich zu älteren USB-Versionen. Die Qualität und Zuverlässigkeit von SanDisk-Produkten haben mich nie enttäuscht, und das SanDisk Ultra USB 3.0 Flash-Laufwerk bildet da keine Ausnahme. Es hat eine solide Konstruktion und ist langlebig, so dass ich mir keine Sorgen um mögliche Ausfälle oder Datenverluste machen muss. Ein kleiner Nachteil ist möglicherweise die Kappe, die das USB-Ende schützt. Sie kann leicht verloren gehen, wenn man nicht aufpasst. Es wäre praktisch, wenn das Laufwerk eine integrierte Kappe hätte, um dieses Problem zu vermeiden. Insgesamt bin ich mit dem SanDisk Ultra USB 3.0 Flash-Laufwerk sehr zufrieden. Es bietet eine kostengünstige und zuverlässige Möglichkeit, Daten zu speichern und zu übertragen. Die handliche Größe und der einfahrbare USB-Stecker machen es besonders praktisch für den täglichen Gebrauch. Ich kann dieses Laufwerk jedem empfehlen, der eine einfache und effiziente Lösung für seine Speicherbedürfnisse sucht.

Ich habe mir den SanDisk Ultra USB 3.0 Stick mit 128 GB gekauft und bin sehr zufrieden damit. Die Übertragungsgeschwindigkeit von bis zu 130 MB/s ist wirklich beeindruckend und macht das Kopieren von Dateien, Fotos oder Videos richtig schnell. Im Vergleich zu älteren USB 2.0 Sticks merkt man deutlich den Unterschied. Besonders gut gefällt mir, dass man mit der SanDisk Secure Access Software seine Daten mit einer 128 Bit AES Verschlüsselung schützen kann. So bleiben sensible Dateien sicher, was für mich ein großer Pluspunkt ist. Auch mit der Kompatibilität gab es keinerlei Probleme, der Stick funktioniert sowohl an meinem Laptop als auch an meinem Fernseher und Autoradio. Die Verarbeitung ist hochwertig, das Design schlicht und robust. Trotz der kompakten Größe liegt der Stick gut in der Hand und wird beim Gebrauch nicht zu heiß. Fazit: Ein schneller, zuverlässiger und sicherer USB Stick mit viel Speicherplatz und toller Leistung. Ideal für alle, die große Datenmengen bequem und sicher speichern oder übertragen möchten.
