While such configurations deliver on the 20Gbps promise, they are not particularly power-efficient.6 Pin To 8 Power Cable China Suppliers - CableCreation/8 Tube to 1/2 NPT Male 304 SS Pipe Compression,6 Pin To 8 Power Cable OEM/ODM - CableCreation.Thunderbolt 3 to 2x Mini-SAS Ports (SFF-8088) Cost-effective, high-speed, mass-storage RAID solution for Thunderbolt 3 Connectivity Integrated RAID 0, 1, 5, 6, 10, 50 & JBOD Support Directly supports up to 8x 6Gb/s SAS or SATA drives and up to 112TB of Storage Capacity Works with any Thunderbolt 3 capable Mac or PCThe power efficiency aspect changed earlier this month with the introduction of the Kingston XS2000 portable SSD. Many device solutions have turned up in the retail market over the last couple of years – all of them have been based on ASMedia's ASM2364 bridge chip, with a discrete PCIe 3.0 x4 NMVe SSD downstream of the bridge. The USB 3.2 Gen 2x2 (20Gbps) ecosystem has been slowly gaining traction. This article refers to Thunderbolt 1 and Thunderbolt 2.Thunderbolt SSDs are at the top in terms of both performance and price, but the last few years have seen various high-end portable SSDs with a USB interface. Learn about the Apple Thunderbolt cables and adapters that you can use with your Thunderbolt-capable Mac. The growth has mainly been in in bus-powered flash-based storage devices.Thunderbolt is a revolutionary I/O technology that supports high performance data devices and high-resolution displays though a single, compact port.The firmware used in the Kingston XS2000 and the reference design are pretty much identical, with the only difference being the absence of the casing and thermal solution. Use the external power plug at the adapter.1.Looking to show off their new controllers, Silicon Motion sent across a bare reference board on which the Kingston XS2000 is based. Additional 12V power might be required for some 3.5 HDD.
![]() Thunderbolt 1 To Sata Cable Mac Or PCThe2.5GBps+ class: Thunderbolt SSDs with PCIe 3.0 x4 NVMe drives Traditionally, these portable drives have fallen into one of the six categories below, depending on the performance profile and the components used. Thanks to rapid advancements in flash technology (including the advent of 3D NAND and NVMe) as well as faster host interfaces (such as Thunderbolt 3 and USB 3.2 Gen 2x2), we now have palm-sized flash-based storage devices capable of delivering 2GBps+ speeds. IntroductionExternal bus-powered storage devices have grown both in storage capacity as well as speeds over the last decade. Except for the analysis of the thermal design aspects / temperature profile, it also tracks what consumers can expect from the Kingston XS2000 portable SSD. 400MBps+ class: USB 3.2 Gen 1 SSDs with SATA drives 500MBps+ class: USB 3.2 Gen 2 SSDs with SATA drives 1GBps+ class: USB 3.2 Gen 2 SSDs with PCIe 3.0 (x4 or x2) NVMe drives Macos iconThe SM2320 USB 3.2 Gen 2x2 controller actually promises 2GBps+ speeds, while the SM2321 USB 3.2 Gen 2 enables 1GBps+ flash drives. However, they managed to get their design wins shipping along with the public announcement of their SM2320 and SM2321 controllers. The Crucial X6 Portable SSD lineup was upgraded earlier this year to utilize the Phison U17 controller, but the U18 controller doesn't seem to have hit retail yet.Silicon Motion, on the other hand, was late to UFD party in terms of putting out their press release. While we were not on Kingston's sampling list for the end product, the SM2320 reference design gives us quite a bit of insight into the XS2000's operations.The SM2320 board measures 62mm x 25.4mm x 5mm, and weighs a puny 7g. Integrated security features preventing hardware-based security attacks possible in a bridge chip / NVMe SSD solutionSilicon Motion sent across their 1TB SM2320 reference design for evaluation around the same time that Kingston started sampling their XS2000 portable SSD (based on the same board). Reduced space requirements leading to more compact UFDs More space on the PCB to integrate additional flash packages for extra performance Reduced BOM cost, leading to lower retail price for the consumer products The advantages of a native UFD controller over a combination of a bridge and NVMe controller are self-evident: ![]() In this review, the SM2320 and SM2320XT are used interchangeably. A small note is in order here: While the Silicon Motion UFD controller is the SM2320, it is often interpreted by monitoring programs as the SM2320XT due to its DRAM-less nature. S.M.A.R.T Passthrough - CrystalDiskInfoThe table below presents a comparative view of the specifications of the different portable SSDs presented in this review. The temperature monitoring worked well, though. Since the program handles each bridge chip differently, and the SM2320 is quite new, many of the entries are marked as vendor-specific, and some of the capabilities (such as the interface) are deciphered incorrectly. Despite its USB 3.2 Gen 2 (10Gbps) performance rating, and its quadrupled capacity point, we believe it offers insights into the power efficiency possible with non-dual chip solutions.CrystalDiskInfo provides a quick overview of the capabilities of the internal storage device. Since the Quartz Canyon NUC doesn't have a native USB 3.2 Gen 2x2 port, Silverstone's SST-ECU06 add-in card was installed in the x4 slot. This still allows for two add-in cards operating at x8 (x16 electrical) and x4 (x4 electrical). In fact, we also added a spare SanDisk Extreme PRO M.2 NVMe SSD to the CPU direct-attached M.2 22110 slot in the baseboard in order to avoid DMI bottlenecks when evaluating Thunderbolt 3 devices. In the absence of a discrete GPU - for which there is no need in a DAS testbed - both slots are available. Testbed Setup and Evaluation MethodologyDirect-attached storage devices (including SD Express cards) are evaluated using the Quartz Canyon NUC (essentially, the Xeon / ECC version of the Ghost Canyon NUC) configured with 2x 16GB DDR4-2667 ECC SODIMMs and a PCIe 3.0 x4 NVMe SSD - the IM2P33E8 1TB from ADATA.The most attractive aspect of the Quartz Canyon NUC is the presence of two PCIe slots (electrically, x16 and x4) for add-in cards. Keeping these in mind, our evaluation scheme for portable SSDs and UFDs involves multiple workloads which are described in detail in the corresponding sections. Game install sizes have also grown steadily even in portable game consoles, thanks to high resolution textures and artwork. High bit-rate 4K videos at 60fps have become quite common, and 8K videos are starting to make an appearance. Over the last few years, the typical direct-attached storage workloads for memory cards have also evolved.
