Raspberry Pi Compute Module 3+ Promises Better Performance, Starts at $25 (venturebeat.com)

The Raspberry Pi Foundation is adding a new device to its suite of miniature computers for industrial and enterprise customers. From a report: The charity today unveiled the Pi Compute Module 3+ (CM3+), successor to the two-year-old Compute Module 3 (CM3). The Pi Compute Module 3+ comes in four variants, starting at $25. The Raspberry Pi Compute Module is derived from the CM3 board but offers better thermal behavior under load. That's possible because of the Broadcom's 64-bit BCM2837B0 application processor, which was also used in last year's Raspberry Pi 3B+, and 1GB of LPDDR2 RAM. The difference between the four variants resides in their storage limits. The CM3+ Lite does not offer a built-in eMMC Flash, whereas other variants include 8GB ($30), 16GB ($35), and 32GB ($40) of eMMC Flash. These eMMC flash chips are more reliable and robust than normal SD cards, the foundation claims.

Functionally, a large SDCard is a hardware RAID0 device, where the large erase unit size is derived from the stripe size.)
