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.

Which M.2 SSD for Linux? (lemmy.world)

In the past, several SSD manufacturers had bugs in their firmwares. So to be sure that I can fix such issues with a newly bought SSD, I need some secure (and somewhat easy) way of updating the firmware.

I don't need to do the update on my own Linux installation. A bootable ISO would be fine, too.

Which manufacturer has some well supported way of updating SSD firmware, even if I don't have any Windows installations left?

Solidigm P44 Pro is a good choice. This model is based on the Hynix Platinum P41, which is well regarded. They provide a bootable linux ISO image for updating firmware, so you can boot that directly, or potentially extract the files and run the updater on your distro of choice. (It's probably best not to do it on an installation running from the SSD, of course.)

I don't see any firmware bug workarounds for these models in the linux kernel sources, which is a good sign.

Solidigm is the company resulting from SK Hynix recently buying Intel's NAND business. They apparently contribute to LVFS, which is another good sign, even if the current model's firmware isn't on there yet.

Have a ready Qemu image of a Windows install. Have a live distro that has (or can install to RAM) Qemu. Boot Windows using Qemu in the live environment, and VFIO-passthrough your NVME as a PCI device. Install and run the official Windows-based update tool, which now has raw access to the SSD.

At least that's what I'm doing for my WD.

Thanks. Nice to know. So I'll not get a WD, then.

To each their own.

I thought that the trick with exposing the raw hardware to a VM was the coolest thing ever, since it negates this entire "do their special tools support Linux" issue. And you do it once every 6 months, maybe 4 times in total, until releases taper off.

But I don't want to deal with Windows at all. Something like this may be acceptable for existing "pre Linux" hardware to have a solution after migration.

But I need new hardware in an environment where no Windows is left.

Any SSD manufactures will fine as long you remember to choose SSD with SLC type for fastest, more durable, less error-prone, and security integration (on this link for further information). With the longest guarantee from the manufactures too will be great for you in long term usage.

For secure thing, SLC is the best option you have as you can see this video from this source that I found week ago. SSD with SLC type will maximize your productivity than other types, while also keep your privacy when you want sell them in the future.

I know the sources I'll give to you are from 2011/13 research like this comment. But as far as I know, this sources are the best explanation that give me deep understanding on how SSD works, rather than just articles or simple explanation things from manufactures with no deep explanation how they methods works. It's up to you to in the end..

choose SSD with SLC

Drives made with SLC flash memory are practically nonexistent. Affordable ones completely so. Times have changed.

Here's a list of models: https://docs.google.com/spreadsheets/d/1B27_j9NDPU3cNlj2HKcrfpJKHkOf-Oi1DbuuQva2gT4

Yes, there are many SSD SLC with afforable price right now too, for example ADATA SU650 I used. The benefit SLC over other types in the video I provide before are after we secure erase our SSD. SLC provide less latency than others, and trim from SSD controller are not enough to clean the data or reduce the latency after using it for long time (based by research in the paper). And from point of security as the main topic in paper, show a good point that SLC give more clean data format than others for privacy minded people (focused on that right now). I'm still searching the latest paper about this topic.. still stuck in this because others not explain well or have proof with research / comparison as this.

No, that is a TLC drive. It only uses SLC for the cache.

Usually you won't be updating the firmware because it's baked into the Linux kernel.

Personally, I've got both a Samsung and Intel NVMe in my PC, they work fine.
