Random thought...

I feel like a #Pcie5 #NVME #SSD could be worth the investment, just for the #OperatingSystem (be it #Linux and its Libraries/Swap or #Windows) and other main-load programs like #Steam and #Firefox (or another #WebBrowser), but the cheapest ones are nearly $200 and they're all at least 1TB... I wonder if we will see cheaper quarter-TB ones in the next couple years, because that feels like it'd be a good way to utilize the PCIe5 NVME slot in my fancy motherboard...

...or I could be wrong: it has been pointed out that PCIe5 drive speeds are mainly only useful for sequential reads, as lookup times create latency comparable to PCIe4, and that makes up the majority of read-time for smaller files. Maybe that can be improved? Maybe Linux distros will implement something that makes core libs load as big blocks? Or we'll have a way to speed up common lookups on the #OS side?

If possible, it'd be good for keeping current-gen #computers relevant over the next decade.

I'd rather like to meet this hardware engineer:

Sensor 1: +33.9°C (low = -273.1°C, high = +65261.8°C)

tl;dr - laptop can survive mordor

Don't get me wrong, I'm glad the Steam Deck is back in stock... and I'm also glad that I got mine before it shot up in price $500 (before GST).

But this is why I'm anti-AI. The #RAM crisis is fucking awful and the prices of #NVMe storage aren't much better. #steamDeck #antiai

io_uring без розовых очков: 5 граблей, которые сожгли мне неделю, и где он реально быстрее epoll

io_uring продавали как убийцу epoll. На деле на HTTP keep-alive разница 0-15%, иногда не в его пользу. Но на NVMe с queue depth 128 - в 3 раза быстрее. Честный разбор с бенчмарками, реальными граблями (SQPOLL, cancel race, partial recv) и почему Google отключил io_uring в ChromeOS.

Friends don't let friends run production etcd on SATA disks (or basically anywhere other than local NVMe)!

I was deploying 50 kubernetes virtual clusters (with vcluster) on top of a bare metal cluster running Talos.

All the nodes had NVMe disks, except one, which had SATA SSD... And it did not go well at all.

I was expecting to see a difference, but not that big. The SATA disks were saturated while the NVMe were hovering between 1-5% of I/O load.

The SATA disks were so overloaded, that I had to kick out their node from the etcd cluster (because the API server was extremely slow).

Oh well, it'll be 100% NVMe on this cluster from now on!
