USB 3.2 Gen 2×2 State of the Ecosystem Review: Where Does 20Gbps USB Stand in 2020? – AnandTech

The easier escape is to buy an off-the-shelf external SSD. There are 3 choices currently in the market, defined here in the order of retail accessibility date:.

Western Digital had tested an evaluation system of the WD_BLACK P50 (1TB version) previously this year, however I had actually put it at the bottom of my evaluation line for a number of reasons. For starters, none of our direct-attached storage testbeds were SuperSpeed USB 20Gbps-capable. The other reason was that the WD_BLACK P50, in spite of its wide retail launch, appeared to be more of a technology-demonstration product, with the ecosystem for SuperSpeed USB 20Gbps still in its infancy. Last month, Western Digital doubled down on targeting the USB 3.2 Gen 2×2 gadget market with the launch of the SanDisk Extreme PRO Portable SSD v2. A review sample was also supplied together with the SanDisk Extreme Portable SSD v2, which was examined in detail recently.

The rest of the review details the actions taken to set up an appropriate testbed for evaluation of USB 3.2 Gen 2×2 gadgets, followed by a conversation of the functions and attributes of the WD_BLACK P50 and the SanDisk Extreme PRO Portable SSD v2. In the last section, we offer some concluding remarks while touching upon the outlook for the USB 3.2 Gen 2×2 (SuperSpeed USB 20Gbps) basic.

USB has become the mainstream interface of option for data transfer from calculating platforms to external storage gadgets. Thunderbolt has actually typically been considered a high-end alternative. USB has made rapid strides in the last decade in terms of supported bandwidth – From a leading speed of 5 Gbps in 2010, the environment moved to devices supporting 10 Gbps in 2015. Late in 2015, we saw the retail availability of 20 Gbps support with USB 3.2 Gen 2×2 on both the host and gadget sides. Practically a year down the line, how is the environment shaping up in regards to future potential? Do the Gen 2×2 devices presently available in the retail market measure up to their billing? What can customers do to take advantage of the requirement without breaking the bank? Western Digital just recently released the SanDisk Extreme PRO Portable SSD v2 with USB 3.2 Gen 2×2 support. A hands-on review of the SSD sets the ideal background for discussing the above elements.

The presently available options for adding a USB 3.2 Gen 2×2 port to systems that do not included one constructed in are noted below:.

Premium motherboards with USB 3.2 Gen 2×2 ports built-in started appearing towards completion of 2019 with the introduction of the AMD TRX40 chipset, followed in the future by the Intel Z490 boards. All these boards made it possible for the function using the ASM3242 controller. Vendors likewise released stand-alone PCIe 3.0 x4 expansion cards to gear up older PCs with USB 3.2 Gen 2×2 (SuperSpeed USB 20Gbps) ports. On the customer devices front, initial demonstrations were carried out with USB 3.2 Gen 2×2 enclosures equipped with PCIe 3.0 x4 M. 2 NVMe SSDs. A few of these enclosures have made it to the retail market. Suppliers such as Western Digital and Seagate have actually likewise launched external SSDs supporting the USB 3.2 Gen 2×2 requirement in the last 12 months

Western Digitals SanDisk Extreme PRO Portable SSD v2 (2TB @ $380).

The USB Implementers Forum (USB-IF) has been hard at work in bringing brand-new features into the world of USB – In the last five years or so, we have seen the introduction of Type-C, and several updates to the USB basic itself. USB4 has been making a lot of news recently (thanks to its application in Intels Tiger Lake, along with the truth that Intel provided its high-performance Thunderbolt 3 specifications for USB4). However, this piece handles the most recent specification update prior to that – USB 3.2 Gen 2×2.

Intro

Coupling any of the above with a high-end NVMe SSD like the SK Hynix P31 (1TB/ $135) or WD Black SN750 (1TB/ $150, or 2TB/ $310) must result in a fast SuperSpeed USB 20Gbps external SSD for around 20 cents/ GB. Note that the SSDs discussed here are specifically those that regularly keep 1.5 GBps+ direct-to-TLC composes without a considerable cost premium.

Unless one relocations to the high-end of the capability line with the 2TB models, the cost-per-GB metric (above 20 cents per GB) is merely not competitive versus the SuperSpeed USB 10Gbps external SSDs that have taken over the market in the last couple of years. We evaluate selected components from the above list in an effort to find the answer.

Western Digitals WD_BLACK P50 (500GB @ $134, 1TB @ $232, and 2TB @ $350).
Seagates FireCuda Gaming SSD (500GB @ $200, 1TB @ $271, and 2TB @ $485.

On the gadget side, among the most cost-effective methods to embrace USB 3.2 Gen 2×2 stays the purchase of a suitable ssd and an appropriate enclosure:.

Yottamaster C5 and Silverstone ECU06.

AbleConn PEX-UB159 and the ORICO PE20-1C.

USB 3.2 Gen 2×2 allows this set likewise to be used for information transmission (when the alternate modes are not needed). At MWC 2019, USB-IF made public the branding strategy for the various USB 3.2 flavors – SuperSpeed USB for USB 3.2 Gen 1 (5Gbps ), SuperSpeed USB 10Gbps for USB 3.2 Gen 2, and SuperSpeed USB 20Gbps for USB 3.2 Gen 2×2. At the exact same show, Phison likewise revealed a single-chip USB 3.2 Gen 2×2/ NAND flash controller, the PS2251-17.

A fascinating aspect to note is that the Silverstone ECU06 and the AbleConn PEX-UB159 do not need any external power. For factors we have not taken the difficulty to examine, the ORICO and Yottamaster cards need external power supplied by means of a SATA power adapter. The Yottamaster C5 and the ORICO PE20-1C both seem to use the very same PCB, with just the branding on the bracket being various.

USB 3.2 Gen 2×2 (or SuperSpeed USB 20Gbps) – A Brief History

Consumers desiring to get into the USB 3.2 Gen 2×2 community can opt to develop a PC with one of the TRX40 or Z490 boards supporting SuperSpeed USB 20Gbps. GIGABYTE was one of the very first tier-one vendors announce such a card – the GIGABYTE GC-USB 3.2 GEN 2×2.

The Test Devices.

The USB Implementers Forum (USB-IF) has been hard at work in bringing new functions into the world of USB – In the last 5 years or so, we have seen the emergence of Type-C, and several updates to the USB standard itself. At MWC 2019, USB-IF made public the branding strategy for the different USB 3.2 flavors – SuperSpeed USB for USB 3.2 Gen 1 (5Gbps ), SuperSpeed USB 10Gbps for USB 3.2 Gen 2, and SuperSpeed USB 20Gbps for USB 3.2 Gen 2×2. Suppliers likewise introduced stand-alone PCIe 3.0 x4 expansion cards to gear up older PCs with USB 3.2 Gen 2×2 (SuperSpeed USB 20Gbps) ports. Customers wanting to get into the USB 3.2 Gen 2×2 community can choose to build a PC with one of the TRX40 or Z490 boards supporting SuperSpeed USB 20Gbps. In the last section, we supply some concluding remarks while touching upon the outlook for the USB 3.2 Gen 2×2 (SuperSpeed USB 20Gbps) standard.

The SanDisk Extreme PRO Portable SSD v2 line will also have a 1TB design, but that will not be available in retail up until later on this year.

Having 2 Gen 2×2 devices in hand, we felt that the standard was getting market traction. To get started with the evaluation, we connected to a number of the aforementioned growth card producers, and Yottamaster was the first to react with a retail sample of the C5 growth card.
