From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Uses for a 2 GB internal USB flash module? (lemmy.ml)

Got my hands on a Dell Latitude ON module. Turns out it's nothing more than a 2 GB flash module that fits in a mPCIe slot and is wired to the USB lanes. Shows up as /dev/sdb.

I do have a couple of old laptops that don't have a secondary SATA drive slot, but do have open mPCIe slots with USB lanes (no mSATA lanes). The Latitude ON module would allow for a dual drive system, albeit a rather crappy one. What would you put on a secondary internal drive if it were limited to 2 GB and USB protocol?

Back in my day, we had this feature on Windows Vista called ReadyBoost that took advantage of the low-latency of flash media to supplement our slow HDDs. I'm not sure if there was a direct replacement for this in the Linux world. There are filesystems that take advantage of faster tiers of storage, but different latency tier exploitation isn't something that I know to be readily available.

Today, 2GB of USB flash is next to useless, but I would consider a homebrew rescue system to restore your backups and fix problems without needing to prepare an external flash drive.
