SanDisk Extreme Portable SSD 1TB up to 550MB/s read Solid State Drive

Product Information

Get fast NVMe™ solid state performance featuring 1050MB/s 2 read and 1000MB/s 2 write speeds in a portable, high-capacity drive that’s perfect for creating amazing content or capturing incredible footage. While Toshiba sells a gaming-specific version of its Canvio external HDD, the Canvio Flex is the current king when it comes to price, performance and value. It’s cheaper than most competitors, yet also one of the fastest portable HDDs we’ve tested. Our PC benchmarks place its sequential read/write speeds over a USB 3.2 Gen 1 Type A connection at 151.5MB/sec and 158.9MB/sec, and there’s precious little in it between the Canvio Flex and Canvio Gaming when it comes to random read/write speeds. Plugged into the Xbox Series X, it’s very competitive with the Seagate FireCuda Gaming Hard Drive, taking four seconds longer to load a saved game in Prey, but coming first by just under three seconds in Red Dead Redemption 2. You can also save a minute or so over slower drives when it comes to moving or copying installed games. Sure, it’s nowhere near as speedy as an SSD, but if you just want a drive for archiving Series S/X games and playing your old Xbox One favourites, this could be all you need. Remember: no matter how fast the port is, if the hard disk or SSD within the drive can’t run fast enough, you won’t see any benefits. The same goes if your computer doesn’t support that connection speed; you’d be surprised how few desktops and laptops have even a single USB 3.2 gen 2×2 port. It’s also built to withstand working in extreme conditions, thanks to an ultra-rugged aluminium and rubber enclosure that’s IP68 dust and water resistant, 3m drop resistant and 4,000lb crush resistant. It is extremely pricey, but if you want the fastest, toughest drive in town, then you’re just going to have to pony up the dough.

Just how much faster is it to access data stored in flash cells? Typical read and write speeds for consumer drives with spinning platters are in the 100MBps to 200MBps range, depending on platter densities and whether they spin at 5,400rpm (more common) or 7,200rpm (less common). External SSDs offer at least twice that speed and now, often much more, with typical results on our benchmark tests in excess of 400MBps for the slowest ones. Practically speaking, this means you can move gigabytes of data (say, a 4GB feature-length film, or a year's worth of family photos) to an external SSD in seconds rather than the minutes it would take with an external spinning drive.

The best external hard drives you can buy in 2023

ROTATIONAL SPEED. If you're talking about a rugged platter hard drive, as opposed to an SSD, drive rotation speed matters—but only a little. It's the rate at which the physical platters inside the drive spin, and it used to be a significant determining factor in overall performance. But these days, many models spin at a modest 5,400rpm or thereabouts, or have a variable spin rate, rather than the 7,200rpm that used to signify performance-oriented drives. This means that much of the speed will be wasted on the Xbox Series S/X and PS5 consoles, where the P50 could be used to store games you aren’t playing or run last-generation titles. On a fast PC with the right connection, though, it’s an absolute beast. It’s also happy working in the most demanding content creation apps, making it one powerful and versatile external drive.

We hooked up each external hard drive to a current-generation Dell XPS 17 laptop, using the best connection interface available to that drive, always in the same port, to minimize performance differentials. Open the enclosure and disconnect the drive. Then, connect the drive to your desktop or laptop, following the manufacturer's instructions. This new drive from Toshiba has a few advantages over older favourites from Seagate And Western Digital. First, it’s relatively fast by HDD standards, with sequential read speeds of over 150MB/sec and write speeds of 160MB/sec. It’s actually a smidgen faster than the excellent Canvio Gaming. And while its random read/write speeds aren’t anything to write home about, they’re no worse than those of comparable drives, and we’d recommend an SSD these days for actively running Windows apps or games. Most such multi-bay devices are sold without the actual hard drives included, so you can install any drive you want (usually, 3.5-inch drives, but some support laptop-style 2.5-inchers). Their total storage capacities are limited only by their number of available bays and the capacities of the drives you put in them. The storage industry refers to these (as well as smaller-capacity externals as a whole) as DAS—for "direct attached storage"—to distinguish them from NAS, or network attached storage, many of which are also multi-bay devices that can take two or more drives that you supply. (See our separate roundup of the best NAS drives.)An added benefit, of course, is that the Seagate Storage Expansion Card is also extremely fast, and we were able to transfer the entire 104.6GB Red Dead Redemption 2 file in less than three minutes during our tests. If you’ve got the money, and you’re fast approaching the upper limits of your Xbox’s internal storage, then there’s simply no better external storage option at the moment. A footnote about the branding. G-Tech (from which G-Drive is derived) started life as part of HGST, which was acquired by Western Digital. G-Tech survived as a rival to Seagate’s LaCie, supplying rugged, external, reliable storage devices and accessories to outdoor enthusiasts, prosumers and professionals. With the recent launch of Sandisk Professional, it is likely that G-Tech and G-Drive will be sunsetted in the near future.
