Well, that didn’t take lengthy. A number of brief weeks after reviewing the Samsung T7, SanDisk’s Extreme Portable Pro SSD (1TB) confirmed up at our door and simply surpassed its rival for the top-performing USB 3.1 Gen 2 drive. SanDisk’s drive doesn’t provide the T7’s useful and enjoyable fingerprint safety, but it surely’s about the identical worth and affords software-based password safety if safety is a priority.
This assessment is a part of our ongoing roundup of the best external drives. Go there for info on competing merchandise and the way we examined them.
Design and options
The Extreme Pro Portable SSD is a bit bigger than the previous iteration, measuring roughly 0.4 x 2.25 x 4.34 inches, but it surely’s nonetheless compact sufficient to reside comfortably in a shirt pocket. Unlike the Samsung T7 competitors, there’s an attachment level (a really giant one!) for a lanyard or key ring.
The Extreme Pro Portable is designed with an aluminum chassis and ABS high, and is IP55-rated (Ingress Protection), that means it should fend off mud and low-pressure water. The ingress weak spot with storage units has traditionally been the connection port, however Type-C ports, such because the one on the Extreme Pro, are much better sealed than earlier varieties.
Note that the IP score signifies survivability when disconnected. With electrical energy flowing by way of a cable connection, fluid can brief cable pins, inflicting digital injury.
The Extreme Pro Portable SSD lacks the fingerprint reader that graces the Samsung T7; nevertheless, it does include SanDisk’s personal SecureAccess software program safety resolution. It supplies password safety for the drive’s 256-bit AES encryption (when enabled), although it should, after all, be put in on any gadget or PC from which you want to entry your knowledge—not as handy. Neither drive is FIPS 140-2 licensed (Federal Information Processing Standards safety), which is able to restrict enterprise curiosity and rule it out for conforming authorities companies.
Why is the Extreme Pro Portable so quick? While it does switch knowledge through speedy USB 3.1 Gen 2 (10 gigabits per second), it is possible much more necessary that the interior storage makes use of the NVMe communications standard, as an alternative of the slower SATA customary utilized by its Extreme Portable SSD predecessor. Beyond that, SanDisk supplied no particulars, and I didn’t need to destroy the drive to seek out out what’s inside.
The WD retailer (SanDisk’s father or mother firm) sells the Extreme Pro Portable in three sizes: 500GB for $120 at the moment, 1TB for $230 at the moment (the scale we examined), and 2TB for $430 at the moment. We discovered the identical costs on main on-line websites: 500GB for $120 on Amazon and 1TB for $230 on Amazon. The five-year guarantee is in impact regardless of the place you purchase.
SanDisk squeezed much more efficiency throughout the board from the Pro model, a lot in order that it’s the quickest USB SSD that we’ve see up to now. Burst efficiency is roughly on a par with the Samsung T7’s, but it surely blows that drive out of the water throughout lengthy writes. All the outcomes proven beneath are from the 1TB model SanDisk despatched us.
CrystalDiskMark 6 rated the Extreme Pro, Samsung T5, and Samsung T7 drives almost equal, however as I simply famous, real-world testing revealed a definite benefit for the Extreme Pro throughout lengthy writes. In the 48GB write checks proven beneath, this sway was obvious…
Those are eye-opening outcomes, nevertheless, take a look at the 450GB write numbers beneath, the place the benefit grew to become overwhelming.
The major cause for the landslide victory was that the Extreme Pro Portable wrote at a comparatively regular 600MBps or so, whereas the T7 began at over 500MBps and dropped to round 300MBps when it ran out of cache. That occurred at round 4 % of complete capability, or the 20GB mark with the 500GB T7 we examined. More capacious fashions of the T7 will run out of cache later within the course of, narrowing however not eliminating the margin of defeat.
The Samsung T7 is a barely quicker reader, however being a distant second writing actually damage its conglomerate rating within the 48GB checks. How a lot the gradual writing will have an effect on you depends upon how you employ your drive. For small quantities of information, the distinction received’t inform. However, the time you’ll save on writes with the Extreme Pro Portable will inform over the lengthy haul.
Testing is carried out on Windows 10, 64-bit operating on a Core i7-5820Okay/Asus X99 Deluxe system with 4 16GB Kingston 2666MHz DDR4 modules, a Zotac (NVidia) GT 710 1GB x2 PCIe graphics card, and an Asmedia ASM2142 USB 3.1 Gen 2 (10Gbps) card. Also on board are a Gigabyte GC-Alpine Thunderbolt 3 card and Softperfect’s Ramdisk 3.4.6, which is used for the 48GB learn and write checks.
It’s the winner
The Sandisk Extreme Pro Portable SSD is quicker and solely a bit bigger that the Samsung T7. I admit that I benefit from the Samsung T7’s fingerprint swiper, however in any other case, the Sandisk Extreme Portable Pro is the transportable USB SSD you need if you’re coping with giant quantities of information.
