The SanDisk Ultra Dual Drive USB Type-C Flash Drive is compatible with all current operating systems including Windows, Mac OS X, Linux, and Chrome. Dual USB connectors ensure compatibility with all USB 3.1 capable devices. You might see USB-C ports marked with this speed standard.SanDisk 128GB Ultra Dual Drive USB Type-C Flash Drive offers both connection types (USB Type-C and USB Type A), fast data transfer, and is easy to carry along with you. If you don’t see it marked out this way, also look for descriptions like SuperSpeed USB, SuperSpeed USB 10Gbps, and SuperSpeed USB 20Gbp. A true 3.2 connection at 20Gbps speeds will be noted as USB 3.2 Gen 2×2 – which literally means 2 times (“2x”) the speed of Gen 2 (10Mbps). If it’s USB 3.0, you’ll see it written as USB 3.2 Gen 1, while USB 3.1 is indicated as USB 3.2 Gen 2. The 3.2 standard encompasses both USB 3.0 and 3.1 – so how do you tell them apart? Here’s where things can get slightly confusing, thanks to a naming convention change announced in 2019 by the folks who decide this stuff (it’s the USB Implementers Forum or USB-IF). In fact, you might even see USB 3.2 Gen 2×2 on some USB drives, which supports maximum speeds of 20Gbps. While USB 3.2 Gen 2 (previously USB 3.1) is theoretically twice as fast as 3.0, right now you won’t find very many computers or other devices that feature 3.1 ports, so most of the time you’re unlikely to take advantage of the extra speed.īut wait, does your laptop or PC list USB 3.1? Chances are it’s still 3.0. You shouldn’t necessarily get drawn into the hype though. You’ll also see some memory sticks that support 10Mbps. The Ironkey D300S startw at a 4GB capacity but you can find options with 8GB, 16GB, 32GB, 64GB, and 128GB of storage. The only downside is it is expensive, but it is worth it. While operating on the 3.0 standard, the Ironkey D300S blazed through our speed tests, achieving 315.31Mbps read speeds and a similarly impressive 209.31Mbps write speeds – undoubtedly the highest we’ve seen. Without using any emphatic expletives: this drive is fast. Also loaded on the drive is a user manual with additional support information. Be sure to remember your password because after 10 attempts the D300S will automatically delete everything on the drive. The process is simple and only took a minute to complete. When you first plug in the drive, Kingston’s pre-installed software will prompt you to set up a password. The Ironkey D300S boasts FIPS 140-2 Level 3 security – a standard set by the US government – which means it’s tamper-resistant and requires authentication before you can access what’s stored. Here’s an excellent encrypted USB drive for those looking for a secure option for sensitive work documents, especially those who commute or hotdesk. At the time of writing, there’s better availability fromĪmazon US so UK shoppers will have to pay more to have it shipped across the pond. The big downside right now is the availability. The Kioxia TransMemory U365 is available in four capacities: 32GB, 64GB, 128GB, and 256GB. Between the design, speed, and large capacity, this is our recommended memory stick for playback of 4K video. While it isn’t as sleek as the SanDisk Ultra Dual with an all-plastic body, it does have a neat minimalist design with a slide-out connector. In our tests, the U365 breezed past the 150Mbps peak promised on the box, clocking at 224.07Mbps, though write speeds capped at a less impressive 10.06Mbps. It now just described as ‘USB 3.2 Gen 1’, which means the same thing.īut thankfully, it’s still extremely fast. The U365’s original branding marked it as USB 3.0, and despite the update, the speed hasn’t actually changed. After all, Kioxia spun off Toshiba in 2018. If you’re nerdy enough to know the Kioxia TransMemory U365 looks strangely familiar, that’s because it’s a rebranded version of the Toshiba TransMemory U365.
