From what we’ve been told about Magician 8.0, this release combines all the Samsung software tools, including data migration software, PSSD software and card authentication, into a single tool. And that it should support Windows, Mac and Android. Bright, Peter (26 July 2017). "USB 3.2 will make your cables twice as fast ... once you've bought new devices". Ars Technica . Retrieved 27 July 2017. BTW, 10Gbps USB3 introduces a new channel encoding which is more efficient. So while the 5Gbps variant translates to at most ~450MB/s real data (after accounting for channel encoding and protocol overhead), with 10Gbps you get ~1100MB/s. Consequently, Gen1x2 is slower (2x450 = 900MB/s) than Gen2x1 (1100MB/s). But it might work over longer distances.
USB3.2 is supported with the default Windows 10 USB drivers and in Linux kernels 4.18 and onwards. [66] [67] [68]The USB 3.0 Promoter Group announced on 17 November 2008 that the specification of version 3.0 had been completed and had made the transition to the USB Implementers Forum (USB-IF), the managing body of USB specifications. [15] This move effectively opened the specification to hardware developers for implementation in future products. A factor affecting the speed of USB storage devices (more evident with USB3.0 devices, but also noticeable with USB2.0 ones) is that the USB Mass Storage Bulk-Only Transfer (BOT) protocol drivers are generally slower than the USB Attached SCSI protocol (UAS[P]) drivers. [43] [44] [45] [46] Note, we said ‘can be’ because the exercise of testing this drive proved to be much more challenging than we’d anticipated. In January 2013 the USB group announced plans to update USB 3.0 to 10Gbit/s (1250 MB/s). [56] The group ended up creating a new USB specification, USB3.1, which was released on 31 July 2013, [57] replacing the USB 3.0 standard. The USB 3.1 specification takes over the existing USB 3.0's SuperSpeed USB transfer rate, now referred to as USB 3.1 Gen 1, and introduces a faster transfer rate called SuperSpeed USB 10 Gbps, referred to as USB 3.1 Gen 2, [58] putting it on par with a single first-generation Thunderbolt channel. The new mode's logo features a caption stylized as SUPERSPEED+; [59] this refers to the updated SuperSpeedPlus protocol. The USB3.1 Gen 2 mode also reduces line encoding overhead to just 3% by changing the encoding scheme to 128b/132b, with nominal data rate of 1,212 MB/s. [60] The first USB3.1 Gen 2 implementation demonstrated real-world transfer speeds of 7.2Gbit/s. [61] Most computers have USB 3.2 Gen 2, and some only have Gen 1. If you have either of these, there is little logic in buying the T9. Because it will perform much like any Gen 2 SSD design, like the much cheaper Crucial X8 at around 1,000MB/s. Gen 1 connected drives will only see around 450MB/s since that’s the limitation of that interface.

The buffer on the T9 is determined by the drive capacity, with the sizes 22GB, 88GB, and 180GB on the 1TB, 2TB, and 4TB drives, respectively. Our review drive has a 4TB capacity; therefore, the speed difference between the 1GB and 64GB was minor, where it might have been markedly less on the 1TB based on this information. We also saw the introduction of the USB On-The-Go specification with USB 2.0, which allows smartphones and tablets with USB-based connectors to host other USB devices. For example, you can plug a mouse, USB thumb drive, or digital camera into the USB port on a Samsung tablet or Google Pixel phone. USB 3.0 / 3.1 / 3.2 (2008 / 2013 / 2017)
The table below presents a comparative view of the specifications of the different storage bridges presented in this review. Comparative Direct-Attached Storage Devices Configuration
In May 2018, Synopsys demonstrated the first USB3.2 Gen2×2 operation mode, where a Windows PC was connected to a storage device, reaching an average speed of 1600MB/s, [66] [67] which is 66% of its raw throughput. Unfortunately, you usually cannot tell if a laptop’s USB-C port can deliver video just from looking at it. You’ll need to read the computer’s instruction manual or spec sheet or you could just experiment. Initially, the Elite-X PRO refused to use Gen 2x2 mode and instead defaulted to Gen 2 operations, capping the speed to around 1,000MB/s. In 2017, the organization rolled out a 20 Gbps speed for USB 3.x devices. In honor of the new speed, the version number changed for all speeds so the 5 Gbps speed became USB 3.2 Gen 1 and the 10 Gbps speed became USB 3.2 Gen 2 and the 20 Gbps speed became USB 3.2 Gen 2x2. As we mentioned at the outset, USB 4 is based on the Thunderbolt protocol which Intel made freely available to the USB Promoter Group (which it’s a member of, along with many other tech giants), allowing USB 4 to offer Thunderbolt 3 equivalent speeds of 40Gbps; twice that of the preceding USB 3.2 Gen 2x2 standard.USB3.1 Gen2 – new, marketed as SuperSpeed+ or SS+, 10Gbit/s signaling rate over 1 lane using 128b/132b encoding (nominal data rate: 1212 MB/s). The USB3.0 Powered-B connector has two additional pins for power and ground supplied to the device. [54] Even before working directly in Information Technology, Josh had a passion for technology. He rooted Android phones and flashed custom ROMs on them; gamed on all major consoles and with his PCs; and built his own computers. However, it isn’t quite as simple as everyone suddenly being able to benefit from 40Gbps data transfer speeds going forward. More on that later, but first let’s concentrate on detailing the rest of the spec, speed levels aside.
