RAID support for NVMe SSD with Raspberry Pi Compute Module 4 for IIoT

With latest Raspberry Pi Compute Module 4, the Raspberry Foundation added NVMe SSD support via M.2 (PCIe 2.0) interface. Jeff Geerling tested 3 piece M.2 SSD RAID array which is another example how Compute Module 4 is a milestone in IoT applications.

SSD/eMMC benchmark scores for Compute Module 4

With the debut of Raspberry Pi Compute Module 4 and ModBerry 500 CM4 from TECHBASE, another addition came to Industrial Controllers and Edge Automation. New module carried the likelihood to associate NVMe SSD module by means of M.2 slot utilizing PCIe 2.0 interface.

Common test of storage for Raspberry Pi is a solution from James A. Chambers’ blog found here: https://jamesachambers.com/raspberry-pi-4-usb-boot-config-guide-for-ssd-flash-drives/?amp=1. Following test steps allows you to benchmark storage performance and shows a score based on registered storage parameters.

Storage test scores for Compute Module 4

We took our ModBerry 500 CM4 device, utililizing latest Raspberry Pi Compute Module 4 and carried two test:

  • eMMC built-in standard Raspberry Pi Compute Module 4
  • selected NVMe SSD via M.2 slot

Both eMMC and SSD drive perfomed really well, achieving very high benchmark score: 5078 for eMMC and unbelivable 13807 for NVM. SSD. For direct comparison, you can check some tests performed by over 20.000 users of this benchmark here: https://jamesachambers.com/2020s-fastest-raspberry-pi-4-storage-sd-ssd-benchmarks/?amp

ModBerry M500 series with SSD/M.2 support and next level configurability

In 2017, TECHBASE Group introduced an industrial-grade automation controller, based on popular Raspberry Pi 3 board. The device called ModBerry M500 incorporated latest Raspberry Pi SBC and TECHBASE’s standard industrial board to enhance the capabilities of market RPi3.

ModBerry M500 added wide range of I/Os to the board, including RS232/485 serial ports, digital and analog I/Os, 10/100Mbps Ethernet port, USB, 1-Wire and optional CAN. ModBerry series also offers additional wired interfaces and wireless communication modules with their proprietary modules called ExCard. The range of wireless modules include 3G/LTE, NarrowBand-IoT (NB-IoT), Wireless M-Bus, ZigBee, LoRa, Sigfox, Wi-Fi, Bluetooth and many more.

Rasbperry Pi 4 upgrade of ModBerry M500

In 2019, with the premiere of Raspberry Pi 4, TECHBASE upgraded their ModBerry M500 device with the latest revision of this popular SBC, further enhancing the performance of their device. New 1.5GHz quad-core 64-bit ARM Cortex-A72 processor (approximately 3 times better performance than previous Cortex-A53 powering Raspberry Pi 3+ Model B and Compute Module 3 and 3+). ModBerry M500 can now be configured from 2GB / 4GB LPDDR4 SDRAM options.

Revised ModBerry M500 features Gigabit Ethernet, USB3.0, two microHDMI ports supporting OpenGL ES 3.x and 4Kp60 hardware decode of HEVC video. The device is fully compatible with previous versions of Rasbperry Pi based Industrial IoT devices and accessories from TECHBASE.

M.2 SSD support for ModBerry M500

Latest software update for Raspberrry Pi 4, now available in beta, makes it possible to boot directly from USB 3.0 connected drive, without the need for an SD card. With a possibility to run the OS directly from SSD is a massive breakthrough, allowing users to improve the performance of the system and data access speed.

ModBerry M500 offers now a feature to include M.2 SSD drive in industrial-grade device. The merge of industrial interfaces and SSD-boosted Raspberry Pi 4 is a perfect solution for on-site data management and gateway application.

ModBerry M500 roadmap for 2020+

Difficult times of coronavirus outbreak in early 2020 changed the expectations for new Industrial IoT devices. Slowed market needed some adjustments to overly expanded devices with reserve of not quite necessary features for different applications – often raising the price of the device.

New addition to ModBerry M series and Industrial IoT Ecosystem offered by TECHBASE Group is the revised ModBerry M500 Lite device, to ensure the full configurability of device’s resources.

ModBerry M500 Lite features:

  • Quad-core ARM Cortex-A72 1.5GHz processor
  • 2/4GB and new 8GB LPDDR4 RAM option
  • SSD M.2 support for mass storage boot
  • Industrial-grade enclosure with DIN-rail mount
  • RTC

ModBerry M500 Lite optional resources:

  • Serial RS232/422/485 ports
  • Digital and Analog I/Os
  • Relays
  • 10/100Mbps Ethernet
  • CAN, 1-Wire
  • M-Bus Master / Slave
  • TPM Security chip
  • OLED 0.96” screen
  • SuperCap UPS

New ModBerry M500 Lite not only is a versatile device with wide array of available optional resources, but also incredible fast with quad 1.5GHz processor, up to 8GB RAM and last but not least, M.2 SSD bootable drive for system, applications and rapid data availability, without the need to bootstrap an SD card. RTC with watchdog option and additional TPM Security chip ensures data safety and breach protection.

Pricing and availability of ModBerry M500 Lite
