Fujifilm LTO Ultrium8 Magnetic Tape Can Store up to 30TB of Compressed Data

Fujifilm magnetic tape

What year is this? 2019. So I was a little surprised when I saw the news about Fujifilm recently releasing a 12TB magnetic tape, as I truly thought those were relics of the past. But apparently, magnetic tapes are still a thing in some countries such as the United States in applications where a large amount of data needs to be stored over an extended period of time. Fujifilm LTO-8 (Linear Tape-Open Ultrium8) data cartridge was unveiled last month with 12TB native capacity, up to 30TB compressed capacity, and data rates of 360 MB/s. Fujifilm is said to be the world’s largest manufacturer of magnetic tapes, and since there’s virtually no demand in Japan, most of the tapes are exported. Nikkei Xtech reports the maximum capacity of the new magnetic tape is double the one of Fujifilm’s LTO-7 previous generation magnetic tape. The LTO-8 cartridge includes a 960m-long, 1.265cm-wide magnetic tape with  6,656 tracks for data and the magnetic head …

Ugoos X2 Cube Android 9.0 TV Box also Serves as a SAMBA Server

Ugoos X2 Cube

Ugoos X2 Cube is a tiny Android 9.0 TV box powered by the latest Amlogic S905X2 processor coupled with 2GB RAM and 16GB flash storage. The new Amlogic processor happens to have a USB 3.0 port which provides good storage performance, and the box is also equipped with a Gigabit Ethernet port, which should make the device especially suitable for network storage beside the usual 4K HDR video playback or streaming offered by any typical Amlogic S905X2 TV box. However in most cases, the firmware provided for such TV boxes does not offer an option to easily configure a SAMBA server (aka Windows network share), so you’d need to either mess up with the firmware configuration yourself, or install a paid app. Ugoos is different since they long have had the option to enable NFS & SAMBA client and/or server in the settings, and Ugoos X2 Cube is no different. Ugoos X2 Cube specifications: SoC – Amlogic S905X2 quad core …

M.4 SSD with PCIe 3.0 x8 Interface Showcased at Computex 2019


M.2 SSD’s are now pretty common and rely on either SATA or PCIe interface, but  apparently there’s a new form factor with an M.4 SSD showcased at the  recent Computex 2019 exhibition, and with Silicon Motion SM2270 controller leveraging a  PCIe 3.0 x8 interface for up to 3,200 MB/s sustained sequential reads, 2,800 MB/s sustained sequential writes, as well as up to 800K/200K IOPS for respectively 4K read/write random operations. Spotted by Anandtech at the event, Agylstor’s M.4 NVMe SSD come with the following specifications: Silicon Motion SM2270 controller with a three dual-core Arm Cortex-R5 processors with 2KB LDPC error correction and 16 NAND channels with 8 CE per channel (128 CE in total) Host Interface – PCIe Gen3 x8 Command Protocol – NVMe 1.3 Max Capacity – 16TB Anandtech explains the M.4 SSD is essentially two M.2 SSDs glued together with (8) NAND packages on each side of the board. The company has now announced when we can expect …

Silicon Motion SM3282 is a Single Chip Solution for Portable USB SSD Sticks

SM3282 USB SSD Stick

Portable USB SSD drives are nothing new, but they are usually implemented using a stand-alone SSD with its own SSD controller combined with a USB to SATA or PCIe bridge chip in order to interface the SSD drive with the host computer or board. Silicon Motion has recently unveiled SM3282 SSD controller that also comes with an on-chip USB 3.2 Gen 1 interface providing a complete single-chip hardware and software solution for portable USB SSD sticks. This should enable smaller and cheaper USB SSD drives. Some of the key features of the SM3282 controller include: Peak sequential read and write transfer speeds of over 400MB/sec Supports USB 3.2 Gen 1 type A and type C Crystal-less design for bill-of-materials cost savings Built-in 3.3V/2.5V/1.8V/1.2V voltage regulators Supports LED for indicating access status 68-pin QFN package Compatible with Windows 10, Mac OS 10.x and Linux kernel v2.4 and greater The chip also supports the USB Attached SCSI Protocol (UASP) and 2 NAND …

NODE Mini Server V2 is a Raspberry Pi Based Storage Server for the Decentralized Web

Node Mini Server V2 3D View

We’ve previously covered networked hard drive enclosures with Ethernet and/or WiFi running OpenWrt or Ubuntu that allows you to easily and fairly cheaply connect SATA drives to your local network with models such as Blueendless X3. NODE has done something similar with a DIY project featuring a Raspberry Pi 3 Model B+. NODE Mini Server V2 connects the popular SBC to a 2.5″ SATA hard drive over USB and is designed to build out the physical infrastructure for the decentralized web (e.g. IPFS) that would allow users to replace remote servers with nodes that they themselves own and operate. Having said that nothing would prevent you from using this as a simple NAS although performance will not be as optimal as the aforementioned products due to the lack of SATA or USB 3.0 interface, as well as having “Gigabit” Ethernet limited to 300 Mbps. Having said that the design could also be easily be adapted to one of the Raspberry …

Embedded Linux Conference & Open Source Summit 2019 Schedule

Embedded Linux Conference 2019 Schedule

In the last few years, I covered the Embedded Linux Conference and IoT Summit schedules since both were happening at the same time and in the same location. But the Linux Foundation have recently announced the Embedded Linux Conference will combine with the Open Source Summit, so the IoT Summit appears to have been phased out. The full schedule for the events taking place on August 21 – 23, 2019 at the Hilton San Diego Bayfront, USA, has also been released, so I’ll create a virtual schedule with some of the sessions most relevant to this blog. Wednesday August 21, 2019 11:30 – 12:05 – What’s New with U-Boot? by Simon Glass, Google LLC U-Boot is a widely used bootloader in embedded systems. Many users are unaware of the wide feature-set of U-Boot, particularly features added in the last few years. This talk aims to bring users (and prospective users) up to speed on the state of the art in …
