- flaburgan 22d agoBoot time, loading game time, mostly.
- Kye 22d agoIt's nice when using large sample libraries so you can stream them off the drive without as much caching in memory. Local LLM workflows probably also benefit from being able to run models too big for RAM off the drive.
- mikepurvis 22d agoI bet this is a lot of what is driving it on the DC side, and just in general bringing disk closer to RAM as far more conventional database type workloads.
- eddieplan9 22d agoApple’s “LLM in a flash” paper [1] sheds some light on why this can be a big deal, especially if they are working on codesign of model and hardware in this dimension. [1] https://arxiv.org/abs/2312.11514 https://arxiv.org/abs/2312.11514
- Synaesthesia 22d agoIt's very important. Every time you launch an app or open a file it's critical for performance. Also when memory runs out and the OS swaps to disk it makes a huge difference.
- _zoltan_ 22d agoit's very very important, not at all something you can compare to WiFi. data processing, LLMs, model loading, MoE loading, etc, etc relies on very fast storage to keep your GPU saturated.
- t_mahmood 22d agoWhen I was booting from a spinning disk, at that time it took over a minute to boot. I upgraded the system to SSD later, and that same system took less than 20s. That was 10 years ago. Another example as a developer, one particular large project took an hour to build on a spinning disk, on a SSD it takes 2mins So, yeah, it's really noticable improvement
- ezst 21d agoThe big deal of a decade ago about SSDs wasn't throughput, but random read/writes. HDDs can be astonishingly fast, but by their very mechanical nature, they suck at jumping from sectors to sectors to gather small files, which is typical of booting an OS.
- mikepurvis 22d agoUnrelated to disk, I've definitely been thinking about this more on the network side recently. I upgraded to 1.4/900 home fibre a while back and then got a modern Unifi UCG/U6 wifi setup, and while I do get 1.4GB down from my hardwired workstation in an explicit speed test I have yet to get anything close to that on real-world workflows. Torrents, container-pulls, backups, all of it seem to cap out around 20-50 MB/s. So while have having this massive almost-symmetric fibre pipe is cool on paper, I haven't felt a huge need to install 2.5G gear all over the house.

- haldean 22d agoIt's definitely important for editing video and doing VFX work, and lots of the editors/VFX folks I know are using Studios. Raw footage from cine cameras now can be 50-100 MB per second now that we have 12 or 18K cameras, and even the low-quality proxies people work with are still pretty heavy, so in-memory caches aren't really an option and stuff is constantly being read from (and cached to) disk.
- toast0 22d agoShould make a big difference when you're running your system off swap cause RAM is too expensive :P
