May look different but genuine Sandisk product confirmed by Sandisk

Reviewed in the United Kingdom on 4 December 2018

I must admit when I received my 64GB Sandisk Flash Drive I immediately took to the comments as something I previously read about a fake made me want to double check. Some of the reviews show two different looking flash drives next to each other and they look different, one looks like Amazon's photo and the other looks like the one I have added. Some others have stated that one flashes and the other and have branded the one I have as a fake. I had my concerns and even reached out to Amazon who let me return said flash drive. I did not however do this and wanted to dig a little deeper so reached out to Sandisk themselves who looked into this for me.

After a few back and fourth with information and pictures I had the confirmation I wanted

Your drive is a genuine SanDisk product. I have already registered the drive under your account and your 5 years warranty period has been validated.

Now the Drive itself is light weight feels solid when the USB is in or out and the data transfers pretty quickly. I knocked off a star because my first attempt crashed after 30% however it has been working ever since.

Should I have any other feedback I will come back and update my review. Any questions please do ask.

Unfortunately received a version reviewers have described as "counterfeit"

Reviewed in the United Kingdom on 9 September 2018

I bought 2 of these, one 64GB and one 32GB, but it seems there are serious issues in quality control from the dispatcher, as the 32GB version I was delivered was clearly different from the 64GB and from the advertised images. The same version this reviewer received: https://www.amazon.co.uk/gp/customer-reviews/R208HUJ91I3UKP/ , it had bent up metal over the connector, other connector differences and no flashing blue light during operation. It was also lighter, and the connector was looser in the casing. It seemed to perform just like a normal drive, but when I realised the flashing blue light was missing that's when I decided to return it, as I shouldn't be receiving an item not conforming to the product specification and advertisements. I won't be buying another SanDisk Ultra after this, but sadly there aren't many good alternatives for USB 3.0 flash drives. Might have to go with the SanDisk Flair.

Note: in pics 1 and 2, the "counterfeit" is on the left. In pics 3, 4 and 5, the "counterfeit" is on the right.

Reviewed in the United Kingdom on 30 July 2018

Colour Name: BlackSize Name: 32 GBStyle Name: SingleVerified Purchase

Product arrived on time a while back - I didn't ever get round to reviewing it. In this case, the product is simply a larger version of the previous USB flash drive I had - the 16GB variant. This one is just as good, with the added bonus of having a larger storage space.

As a student, I've been using the device consistently for a length of time - read and write operations are smooth and at a decent speed, though not break-neck fast. One wouldn't expect tremendous speeds from a device with a memory controller as small and low-power as this, so that's anticipable.

The build quality is decent - the case feels fine when the USB port is retracted, though when it is extended it feels a little flimsy. This is expected - since all the circuitry is on a tiny PCB inside the device, mounted onto the USB port. The case is designed to do the main job of protecting the USB stick, and that it does.

There is a small light, not shown in the photo, to indicate that the device is powered and operational. It has endured countless read and write operations as it is where I transport all of my code and documents - and it comes with a free encryption software.

All in all, the very same kind of excellence I've come to expect from all SanDisk memory.
Don't expect to be blown away - it's just a thumb drive.

But do expect a satisfactory product, and it won't let you down!

Hi speed data transfer and good capacity

Reviewed in the United Kingdom on 27 August 2019

Colour Name: BlackSize Name: 128 GBStyle Name: SingleVerified Purchase

The item was delivered quickly and is exactly what I wanted. The shape means it doesn't quite sit right in the small space dedicated to it in my laptop bag. Not sure why they can't make them rectangular as normal but a small thing. Data rates are great, both read and write.

All right.
People please don't write if you not sure how to get full speed.
First thing you must be sure about usb 3.0 in your system or notebook....
Second think format your usb drive to exfat (by standart it's fat32 or ntfs) . Exfat have no limits on single size file.
Third think if you got true usb 3.0 and right format Exfat. Be sure that in your system controller got correct driver installed - to be true stok driver don't give you full speed.

And yes its hot on full speed 100% . Controller on usb flash gets hot in 2-3 mins but no issue.
Please right useful competent comments.
Good luck fox ;-)

Low-Quality

Another reasonable , reliable and nicely priced offering from Sandisk. With decent speeds too.

Reviewed in the United Kingdom on 4 May 2021

Colour Name: BlackSize Name: 64 GBStyle Name: SingleVerified Purchase

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 .

Seems like a Good Memory Pen. Beware Slow Tranfer Speed

Reviewed in the United Kingdom on 20 June 2020

Colour Name: BlackSize Name: 256 GBStyle Name: SingleVerified Purchase

Just opened it and there is 232 GB space (not 256 GB as advertised). Still a huge amount.

Inserted into the blue USB slot, it copied 11,967 items (worth 38 GB) from my 8-yr-old laptop onto the memory pen in 1 hour 31 minutes. Idk if this is really bad or reasonable, or if my old laptop is to blame. But it was a one-off big transfer so I'm not too upset.

It does flash blue during file transfer and when browsing files. I'm glad about that, as a reviewer from 2018 said counterfeits don't light up.

It quickly got a bit warm to the touch during the file transfer (not boiling hot tho). And now plugged into my new laptop for just browsing the files, the memory pen feels cool again, maybe a teeensy bit of heat.

It has a security feature where you can drag your files into a password-protected bit if you want to use that.

I spent ages researching which memory pen I should get lol. And I'm happy enough that I went with this one. But maybe I should have paid more for a 400 MB/s speed.

Not too bad for the price

Reviewed in the United Kingdom on 6 July 2020

Colour Name: BlackSize Name: 16 GBStyle Name: SingleVerified Purchase

I don't find these sandisk usb sticks too bad for the price, they seem to have excellent read speeds and reasonable write speeds.

However over the last 6 months I've purchased 5 of the 16gb sticks all at different points in time, all direct from Amazon, no third party sellers. All of them have the same model number SDCZ48-016G but some are made in Malaysia and some in China and there is a difference.

When I ran a benchmark using CrystalDiskMark I found the read speeds for sequential reads were about the same only a few mb/s difference, but for the write speeds the one made in Malaysia benchmarked at 30mb/s whereas the one made in China only reached 14 mb/s.

I guess Sandisk get away with this by only stating the read speeds and not having to state a write speed or just state that write speeds are untested.

I bought several of the TRIPLE packs.

Reviewed in the United Kingdom on 22 February 2022

Colour Name: BlackSize Name: 32GBStyle Name: Triple PackVerified Purchase

I tested several of these. Some included a few Sandisk Security files. Some devices will format drives and remove these. Having spare drives not formatted means these can be useful if required. The slie feature on the connector helps with many USB connections but some connectors could be extra tight and not prove as user-friendly. The handle feature is quite thin and slippery to handle so take extra care to hold and not let fall to the floor. The USB3 option is much faster than the USB2 so why buy the USB2 drives? USB3 32GB info clearly seen on the back of each drive. A serial number is shown above the SDCZ number. USB drives over 32GB may require a software program to format these correctly, so use Google search for extra info. When Sandisk USB3 drives are bought in bulk and reduced by Amazon's discount deals the prices are even more reasonable. As soon as my tests stopped storing Freeview recordings with a set-top box I have I was able to switch to a different USB3 drive and continue that way instead. I could then use the PC to transfer recordings to from several of these drives. Once emptied again, I separated the Sandisk drives for future use as many devices seem to favour the 32GB drives such as the Kingston DataTraveler drives. So check bulk buys when possible.

Sandisk USB3 mem stick -Are USB sticks the same?

Reviewed in the United Kingdom on 26 November 2019

Colour Name: BlackSize Name: 32 GBStyle Name: SingleVerified Purchase

Owning quite a few usb mem sticks, I have come to know some of the good and bad points about them. These sandisk ones are quite reliable and apart from the odd glitch that a format has cured they have been trouble free. The one thing that seems to let most of them down, this sandisk included is the design. This is of the slider type which is ok, but unfortunately the case is very thin plastic and if like me you keep it on a key ring, it won’t be there for long because I expect the plastic where you can use for a key ring will either crack or snap off. A bit of a disappointment really as I expected better. These 32gb ones come with the normal sandisk security program that works but it can be a nuisance. Running in a USB 3 port makes it faster file transfer and it will also work on a USB 2 port but not as fast. No the best for keeping in your pocket as there is nothing to stop fluff getting into the interface which will stop it from working. A cheap throw away item that with care will last and store files reliably. Better designs are available, but you will pay more.

Does The Job

Reviewed in the United Kingdom on 24 May 2022

I've been using SanDisk products for years and generally found them to be very reliable. I bought this to put photos of a wedding a photographed on, and it was quick and easy to use. The sliding USB plug is mildly fiddly, but other than that I would recommend it if you haven't already gone taken to storing your files on "The Cloud" by now.
