Customer Ratings & Reviews

Very reliable And affordable. The transfer speed is lightning fast for a movie and it's very convenient for keeping secure documents.

This was a great flash drive for a great price. I can’t recommend this flash drive enough. Five stars!

This was a great USB at a really fair price. I bought 3!

Cloud continues to be all the rage in 2019, and SanDisk is riding the wave with the new SanDisk Ultra USB thumb drive. It offers a generous 256GB of storage for a reasonable price, but also includes a year of cloud backup for said drive. 256GB of cloud storage for a full year is included making this disk an excellent value if you are looking for a cost effective backup drive. The SanDisk Ultra 256GB is not overly different from other SanDisk drives. It's clad in a semi-gloss black with a slide mechanism to protect the type-A usb port when not in use. It's a tried and true design, and SanDisk rightfully doesn't mess with what works. Performance wise, the disk boasts performance up to 100MB/s. This claim is not exaggerated for sequential read speeds (in other words, large files). Crystal disk mark placed sequential read speeds around 135MB/s. The drive appears to use a fast write cache buffer. Sequential writes hover around 65MB/s for the first gigabyte or so but sharply and predictably drop off to 20-25MB/s. Writes in bursts benefit from this cache, but it can easily fill up during large writes. The cache recovers pretty quickly however, so writing performs well in small batches. This squarely puts the SanDisk Ultra in the budget category as far as performance goes. The real interesting proposition with this drive is the cloud storage that comes with it free for the first year. You can backup all the data found on your drive - meaning that if you have a 256GB drive, you can backup that amount of data to the online 'FlashBack' service. I tested this theory by copying our family photos of around 70GB to the drive. While this took quite a while to accomplish, the backup took place during the copy, so I left it overnight. The FlashBack service not only had a copy of all my files, but presented them with a friendly photo browser, and broke down my files based on metadata, type, and provided a handy search feature. The user interface is modern and worked well with my files. You can share links to files, which is a plus, and manage those links. Essentially you could share out a document with someone, and then revoke the access to that link by simply deleting the sharing link. It's clear there was a lot of time spent to ensure a positive user experience with this service, which is appreciated. The app used to do the backup is unobtrusive and seemed to work well. It does get angry if it’s in the process of backing up files and you unplug it. It does take time to get to resuming a backup. If you delete files, they’ll go in the ‘Trash’ bin in FlashBack, and can be restored for up to 30 days. The first year is on the house, but after that pricing looks reasonable. At $9.99 for the 256GB drive a year, it’s hard to argue that’s a bad deal. Having access to any of your files remotely and securely even with your pc off, and your thumb drive in the drawer is a nice selling feature. Do keep in mind that while SanDisk does look like they did a decent job with security, while still being able to provide sharing features, etc - it’s still hosting your data remotely. Be sure to secure your account with a good password. I’d like to see them implement two factor authentication to help bring further peace of mind to those backing up sensitive data and/or financials. The SanDisk Ultra 256GB is a decent performing everyday USB pen drive with a large capacity. The real selling feature of the Ultra series here is the FlashBack service, and it seems to really hit the nail on the head. If you’re looking for a good backup drive that can double as a carbonite or other backup service replacement - this might fit the bill if your needs are simple. In any case, it’s a decent alternative to using Google Drive and offers a ton more storage for the money (and gives you that storage free the first year). This new model of storage actually seems pretty compelling, I highly recommend trying it out.

This Sandisk Ultra Plus 256gb usb 3.0 flash drive is really a must have for people that need to store movies, audio books, photos, videos, & files of any kind from their mac, pc, or laptop. This 256gb usb flah drive is super fast and quite easy to use - just plug in & transfer your files to the drive! I have already loaded my apps, music, & personal files onto it, so my laptop runs much, much faster! I experienced no issues what so ever with this device. Sandisk is a top brand for its flash drives and micro sd cards, so I feel confident about its performance and longevity. The flash drive has so much storage space on it and my files are safe & organized. The quality and performance is great! I would absolutely recommend this flash drive to my friends & family. I would definitely buy this product again! Especially since the cost of this flash drive was really reasonable.

I like the Sandisk usb flash drives because of how simple they are to operate. They are reliable, fast and how a good amount of storage at a great price. I alos like how the the thumb drive has a slide to protect the usb connection.

I purchased this item primary because of the price and capacity. I have a ton of USB 2 sticks but this one seems promising. I have used it pretty heavily in the last month. - Bootdisk for reloading my MacOSX. - Storing backup software to reload while I am offline on new systems - I have even used it for temp caching on a data mining project due to the device I was currently on it was very limited on ram/hdd space. It held impressively and did not unmount under very heavy load. I was very tempted to buy a few more but after since I primary either have it in my laptop bag or key-chain it opens very easily (its obviously designed to be on a key-chain and mobile has the loop on it). It Drives me nuts. That is the only reason I took off a star. Yes I know they have a carrying pouch but I am not very interested in buy another product for something I feel should be handled on here. It should not be that difficult to add either a locking mechanism such as a pocket knife has or perhaps stiffen up the sensitivity of it opening up. Other than that I would strongly recommend the product for the price and quality. If I was not so mobile I would own several more!

This flash drive works well. It keeps all my pictures in an easy-to-carry unit The price was good and I needed something to reduce the amount of storage in my phone. This was a good solution. I recommend this flash drive if you need to keep some memory but reduce your phone's load.

This disk is great. The slide mech works smooth. The size, space and price are perfect.

Easy to use. Reasonably priced. Fits my key chain.

A Flash Drive unlike any other, the fastest with biggest gigabits and yet affordable!

I needed a second flash drive to archive a big set of documents, and this was the perfect choice: a large capacity, fast and reliable operation and a good price.

I needed a big flash drive to upload all of my wedding pics. After reading reviews I decided on this one because of the size, the speed, and the price. It did the job great!

It's big, it's fast and the price was a perfect match for my wallet. I probably should have bought more because devices like this make great birthday and Christmas gifts.

To think you can get this much storage in such a small package at such a great price. I use mine to store movies to move back and forth between my computer and tv.

No spinning disc to be affected by motion, with storage on a par with portable hard drives at a decent price. Very easy to carry around.

Great flash drive with lots of storage for a great price. USB 3.0 is great for high speed transfers.

Great product for the price and storage amount. Fast transfer for USB 3 and 2. Highly reccomend this product if you can get it in sale.

Plenty of space for my needs and very fast when transferring files. Will be getting one more for my wife. Great price Best Buy !!!

Crazy to think they can provide such large amounts of space in such a little device! Excellent transfer speed and amazing price!
