I bought the *previous version* of the Ultra Fit around 2016, and it started off pretty great - usually full USB 3.0 speeds for read, and a decent ~40 MB/s write. Not bad for the deal I got on the drive back then. Then, once I started putting more than 5GB of files on it (years later), its issues started showing up. Drive got very hot, and often ejected itself (Windows would do the unplug and replug sound). Move it to a USB 2.0 port, and the issues were gone, but you'd rarely beat 20MB/s writes. Now (of course after the warranty period), but after having written less than a terabyte or 2 on the drive, the drive is dying. With use on USB3 making errors and/or ejecting itself, I can only use it on USB2, but it now writes at ~6 MB/s, and I wouldn't be surprised if it ...

But I don't.Great look, it was on my keychain for years and I didn't even loose the cap, but alas, the design is clearly heavily flawed, and these small drives just can't cool themselves fast enough. At least, not the SanDisk ones. I would have recommended it as a USB 2 drive, but even so, it seems like it can't even handle more than a dozen overwrites, which is woefully low for any flash tech (and this must have been TLC or better). That, or the heat killed it.

There are two companies involved here: Sandisk (hardware) and SecurStick (software). What you're paying for is the hardware, so I'm rating this 5 stars, but beware that the software is really pithy, and not always stable. They turned off about 1/3 of the features and made it very clunky to use, to "encourage" (force) people to "upgrade" (pay even MORE money than they already just did) in order to have full functionality and a half-way decent GUI interface.It's also only 128bit encryption "for free" with higher SSL-type numbers available if you cough up more dough. I think that's pretty lame, and SanDisk needs to write their own fully-functional software that doesn't cost their customers anything more than the cost of the hardware itself.

Half the cost of the drive is associated with the "secure encryption" it "comes with," so people are already being charged extra for that in the first place! SanDisk needs to cut the price of all their flash/thumbdrives in half if they're going to stick with SecurStick's software, otherwise, it's a bum deal.Still, as always, the quality of the hardware is excellent! SanDisk is the one brand that can be truested to get the hardware side of storage correct.

I bought this drive in December, 2021 but didn't open the package or begin to use it until October, 2022. Immediately, there were problems: The drive simply quits working during file transfers that last more than a few seconds. It will disconnect and the transfer gets interrupted, which means I need to cancel the file copy process and start again. This has been happening for months, and I don't trust the drive not to fail, so I've submitted it to SanDisk (Western Digital) for an RMA. Fortunately it has a 5 year warranty. Unlike prior generations of this type of drive, it feels light, flimsy, and cheap, with a plastic rather than a metal housing around the USB port. I'm very disappointed in the quality of this product and if I had known how badly it would turn out, I ...

This flash drive is tiny; it's the same size as the wireless mouse dongle it's parked next to on my Surface laptop. If it weren't for the little "handle" on the end of it (the better to make removal easier) the little blivet would be even smaller. I can leave it in place and not have to worry about breaking it off. And I'm guessing this is the the whole obvious raison d'etre for this SanDisk Ultra Fit.The body is made of metal with a thin plastic overlay and a small loop handle at the end. There is no cap to protect the USB end of it, adding to the idea this drive is designed to be left connected. And it's made by SanDisk which, for me, has a reputation of making long lasting and reliable flash drives.So if your looking for a thumb drive you can plug and forget, ...

Ever since Apple Inc. has decided to replace iTunes with that primitive Apple Music app disaster I started using Windows devices to run iTunes. The irony. . .This drive works perfectly for hosting my iTunes library, custom equalizer settings for every song, and playlists for every occasion.In the Apple Music app you can no longer set custom EQ for every song the way you still can do it in iTunes under Windows. When you run a four-thousand-Watt sound rig capable of 137dB, being able to readily equalize each and every track is of critical importance. Some songs can sound dangerously harsh and aggressive without proper EQ. You don't want your audience to suddenly bleed out of their ears!No latency and no issues of any kind with this drive.

It works flawlessly with 64-bit Windows 11. I have it formatted to the NTFS file system as opposed to FAT. Custom equalizer settings for each song are flawlessly loaded every time, sound quality is as good as ever, and the physically small drive is almost too small to notice. I am 100% happy with it.
Lets face it. All USB flash drives are pretty much the same, as long as they have the same capacity, form factor and have the same basic specs. One USB3 256GB drive pretty much works the same as any other.But SanDisk is throwing in a nice little bonus with some of its new models. This SanDisk 256GB Ultra USB 3 Flash drive comes one year of free cloud backup for everything on the drive. It works with a nifty little app called Flashback, which is a breeze to install and setup and works seamlessly every time you plug your flash drive into the computer with the app.Once installed, all you have to do is drop the files you want backed up into the Flashback app and you are done. Since it is USB3, it uploads quickly, giving you a backup copy even if you dont have the flash ... MoreLets face it.

You can even download it from the cloud.As another bonus, you can share files with anyone you choose. Simply click the link icon that appears on the file when you open it in Flashback. It copies a Web link to your cache, which can be pasted into anyone you want to email. They can access the file simply by clicking on the link.Even better, this is not one of those come on deals where you have to give them your credit card and it renews automatically and your credit card charged if you forget to cancel it before the free trial runs out. This deal truly is free. No strings attached. Cant beat that.Advantage SanDisk, if you are in the market for a flash drive.Be aware that although this drives looks identical to some older SanDisk Flash Drives, those will not work with Flashback. The app reports they are not compatible.The app only works with Ultra flash drives like this one and the more compact SanDisk Ultra Fit flash drives.This particular drive is my preferred form factor, ie, not one of those tiny mini USB flash drives that are so easy to lose. Or one twisted into some bizarre shape. This one is an old school traditional size and shape about the same as a thumb with a USB connector that slides in and out.
I have been an avid SanDisk drive fan, whether it be SSD, compact flash, SD, or their older USB drives. However, over the past few years, I have found their USB drives lacking, and getting worse. Previously, I purchased some USB 2.0 Cruzer Glide drives, and found them painfully slow when writing compared to others I had from other companies. This week, I wanted to give them another try by buying the newer USB 3.0 Ultra SBCZ48032G and 128G the price was very attractive when on sale.Bottom line, I am returning the Ultra drives. They are still too painfully slow to use. I bought USB 3.0 drives and expect to get somewhere near that speed I do not expect USB 2.0 flash drive speeds with a USB 3.0 device.Comparing these drives to a PNY 128GB USB 3.0 drive I purchased a few ...

I bought USB 3.0 drives and expect to get somewhere near that speed I do not expect USB 2.0 flash drive speeds with a USB 3.0 device.Comparing these drives to a PNY 128GB USB 3.0 drive I purchased a few years ago, I did some testingbenchmarking. My tests were simple1 Use CrystalDiskMark 7.0.0f to benchmark the drives this is a commonly used tool.2 Copy 15 files, 8.62 GB total from a Corsair MP600 NVMe drive to selected USB Drives all using USB 3.0 ports, and as a checkpoint, to my local NAS this latter to ensure the MP600 NVMe drive was not the bottleneck.Summary see attached picture as well The PNY drive performed well and within what I expected regarding speed. It copied the files quickly, roughly 88 MBs consistently, taking approximately 1 minute, 41 seconds. The Ultra128 ran the benchmarks OK, but when it came to real world usage, it fell on its face after what appears to be that its internal cache was filled it went from roughly 78 MBs down to about 12 MBs after a few seconds of copying. It took approximately 3 minutes, 50 seconds to copy the same data to the Ultra128, more than twice the time required by the PNY. The Ultra32 ran the benchmarks fairly, but its internal cache appears to be smaller, and the 1GB benchmarks picked up on it. Unfortunately, the drive died become read only and I could no longer test it. And for those tech savvy folks out there, yes I did try DiskPart and other tools to fix it. From untimed tests, the 32G drive performed slightly worse than the 128GB drive.These benchmarkstests were performed with a home assembled machine Windows 10 Pro Asus TUF Gaming X570 WiFi motherboard AMD 3800X CPU Corsair MP600 NVMe 1TB Drive Corsair Vengeance memory, running at 3200MHz.SanDisk, time to pick up your game, or someone else will come along and beat you at it.

It's incredibly user-friendly, requiring no formatting—simply plug and play. I do regret not purchasing multiple units during the sale period; it's that good!
