![]() ![]() Once you entered USB 3.2 gen 2x2 and TB3/USB 4 space, you start to see a lot of NVMe SSDs cannot really provide sustained throughput and compatibility issues start to happen (especially when using Apple devices). However, honestly, Samsung T7 1TB is good enough for most people. There are now USB 3.2 gen 2x2 and Thunderbolt 3 / USB 4 external SSDs on the market. It only has to be backward compatible to USB 3.2 gen 2 (or gen 2x1 if you like). Just an FYI, USB 4 does NOT have to be backward compatible to USB 3.2 gen 2x2. Anyway, right now, you can put PCIe gen 4 x4 SSDs in a Thunderbolt 3 / USB 4 enclosure, but it runs in PCIe gen 3 x4 mode.Īnyway, most people probably don't care about the details. Maybe there is technically a way to wire PCIe gen 4 x4 to Thunderbolt 3, but even if that's possible, there will be some bandwidth reduction since Thunderbolt 3/4/USB 4 just doesn't have that kind of bandwidth. So, use PCIe gen 4 x4 eh? Um… nice thinking, but that's not how it works, at least not currently. The issue is using PCIe gen 3 x8 doesn't quite make sense (good luck finding a consumer SSD that supports that) and using PCIe gen 3 x4 means you cannot get the max out of Thunderbolt 3 / USB 4. Problem is, USB4 has the same issue as Thunderbolt 3 (and even Thunderbolt 4). A non-Intel USB4 chipset will take some time to become available. However, a lot of makers are simply re-packaging Thunderbolt 3 external SSDs as USB4. T7 maintains its skin temperatures below 48c at all times, following the Samsung internal quality standards for heat management and safety. ![]() Problem is, the main objective of USB4 is you don't have to use the Intel Thunderbolt 3 chipset. The T7's advanced thermal solution uses the Dynamic Thermal Guard to withstand and control heat, so the compact SSD stays at an optimal temperature even at fast speeds. Note that this chart was corrected after initial publishing to show the T5’s true, and lesser performance.ĬrystalDiskMark 6 rated the Extreme Pro and Samsung T7 drives nearly equal, but as I just noted, real-world testing revealed a distinct advantage for the Extreme Pro during long writes.They have been available (as Thunderbolt 3) for some time now. In CrystalDiskMark, the Extreme Pro was rated as far faster than its predecessor and Samsung’s T5, but only marginaly faster than Samsung’s newer T7. All the results shown below are from the 1TB version SanDisk sent us. Burst performance is roughly on a par with the Samsung T7’s, but it blows that drive out of the water during long writes. SanDisk squeezed a lot more performance across the board from the Pro version, so much so that it’s the fastest USB SSD that we’ve see to date. The five-year warranty is in effect no matter where you buy. We found the same prices on major online sites: 500GB for $120 on Amazon Remove non-product link and 1TB for $230 on Amazon. The WD store (SanDisk’s parent company) sells the Extreme Pro Portable in three sizes: 500GB for $120 Remove non-product link currently, 1TB for $230 Remove non-product link currently (the size we tested), and 2TB for $430 Remove non-product link currently. ![]()
