What is Industrial Grade eMMC?

eMMC has seen strong adoption and become the storage of choice for consumer devices such as smartphones, e-readers and tablets. These small devices all run on battery power and require high-density storage with low power consumption -- at a low cost.

Wish Granted

OEM customers have told us for years that struggles with NAND supply and lack of standards costs them a great deal of time and money. A shortage or EOL on a key component like NAND flash memory can cause product delivery delays that impact topline revenue and potentially company reputation. What they wish for is a "plug and play" option that lets them multi-source their flash memory.

Software Power Consumption

One of the questions we received at Datalight is whether our software affects the power consumption of embedded devices. Not being power experts ourselves, we found an intern and faculty advisor from our nearby University of Washington to help us out with the process.

Comparing Two Protocols for USB Devices

The USB Mass Storage class (also called UMS) is a protocol that allows a device connected through USB (Universal Serial Bus) to become accessible to a host computing device. This allows file transfers between the device and the desktop, as long as the file system used on the device is known to the desktop. One common example of this is the FAT file system.

Why CRCs Are Important

Datalight's Reliance Nitro and journaling file systems,such as ext4, are designed to recover from unexpected power interruption. These kinds of "post mortem" recoveries typically consist of determining which files are in which states, and restoring them to the proper working state. Methods like these are fine for recovering from a power failure, but what about a media failure?

fsck and chkdsk

Before embedded devices, file systems were designed to work in servers and desktops. Power loss was an infrequent occurrence, so little consideration was given to protecting the data.
