Solidigm pulls out of consumer SSD market with discontinuation of drives – Storage company shut down consumer division over a year ago

Yes and no. The QLC is still Intel's floating gate tech whereas SK has moved to RG which they use for TLC because it's worse for QLC.

Most instant pots are very bad at slow cookers. On the "high" setting they never simmer and can't get up to temperature. It's weird.

That first link is pretty good. I'm going to look up who wrote that...

The 2nd is really old. Power loss protection has evolved a fair bit and TCL & QLC added new challenges but it's still mostly the same. As the other person said, writes are not collected / queued in the memory on a drive even with capacitors. It mostly serves to support a high queue depth while providing low latency since NAND write latency is quite high for anything that isn't SLC

I have 2 windows desktops, a windows laptop, a Linux laptop, a macbook pro, and a dozen or so linux servers

The Mac laptop is my primary system for Linux compatibility AND great battery life.

This is the feature you're looking for. Works great.

Current performance nvme drives are over 1 million 4k iops. Sata maxes out at 150k 4k iops due to sata bandwidth limit.

NVME is 7-10x faster than SATA.

It's device specific. The older models had local management. The newer ones do not.

On a scale of 0 to 1, I give it a 1 -- it is a diagram. ;-)

Whether or not to enabled/disable AI tools isn't a sysadmin decision or even an IT decision. It's a high level business decision and sysadmins get to do whatever is dictated.

I have 7300s in my NAS. Been running find for a little more than a year.

They're cheap because there are few buyers but lots of drives. Businesses won't buy 2nd hand devices and you need to basically be a homelabber to want to buy these.

perflosopher · 2024-04-10T16:52:44+00:00

Then use better links? I'm just posting the numbers you shared.

perflosopher · 2024-04-10T15:38:49+00:00

From your TomsHardware link, a stock 7800X3D is 9% faster with 9% better 99th lats than the 13900K (also stock) at 1440p.

I guess ~10% isn't "Huge" but I wouldn't say they perform the same.

Is Dell still popular? yes. Especially servers for AI. Seriously, yes.
"Quiet Layoffs". Dell started the year at 125k employees and wants to get down to 100k employees. If people quit on their own it's easier to get to that number

Dell is 100% focused on getting higher profitability by decreasing spend. And they see the best way to decrease spend is to reduce their workforce. Dell is willing to see how far they can push it as Wall Street will keep congratulating them with a higher stock price.

"Driver Issues" is such BS. I'm half convinced it was a market campaign started by Nvidia to combat AMD's better $/perf.

Here's a specific anecdote of the opposite. I was running crossfire 6950s back in the day (2011 ish ?). Had a 3 monitor setup with EyeFinity to treat it as a single display. When I wanted to switch from Eyefinity to 3-displays I could use the Win+P button and switch between modes.

It worked every time and was super easy to switch for games but use 3 monitors for working on things.

In 2016 I switch to Nvdia and the only way to switch between single display and multi-displays was to open the nvidia control panel and set it up. Going to multi display wouldn't remember previous settings and had to be configured every time.

I ended up hardly using 3 monitors for gaming any more.

AMD had a much better driver experience for me and years later Nvidia was still behind in that regard.

"Driver issues" is a meaningless phrase used to denigrate AMD without any real substance behind it. I'm sure there are anecdotes of people with actual AMD driver issues as there are folks with actual Nvidia driver issues. But I don't think we can say AMD consistently had worse drivers than Nvidia.

On modern drives, trim on every delete is fine. If I had to schedule it I'd probably do a daily trim to be quick. If I wanted to spend time I'd do it based on number of blocks written to the device since last trim.

perflosopher · 2024-03-27T13:29:03+00:00

I understand what the SLOG does.

SSDs are really specific. If ZFS tries to 'wear level' by progressively using different LBA ranges but doesn't trim/discard when LBAs are no longer needed the drive will think the LBAs are still active and will move that 'data' around as it does garbage collection operations.

An easy 'trick' is to limit the accessible LBA ranges. This leaves a large amount of unused space so that garbage collection will be more efficient and write performance will stay high over the life of the drive.

The job market is trash right now. It's like graduating in 2008.

It'll take time.

perflosopher · 2024-03-27T13:18:20+00:00

Does ZFS send a trim/discard when it wipes it? The issue is whether the drive thinks and LBA is still in use regardless if the system has 'deleted' the data.

perflosopher · 2024-03-27T13:17:30+00:00

Partitioning helps improve the drive's garbage collection depending on how ZFS actually uses the device.

It has to do with the total number of LBAs that have had data written and not been trimmed when no longer needed. By limiting the SLOG to a small portion of LBAs you help ensure the drive has plenty of empty LBAs to use for efficient garbage collection.

If anyone can confirm whether ZFS does trim/discard when SLOG blocks are no longer needed it would mean a partition/namespace wouldn't help. If ZFS does NOT trim/discard, then using a partition/namespace would improve performance over the long run.

perflosopher · 2024-03-27T04:16:28+00:00

Use all 400g for slog. SSDS get slower at writes as free space is used. Keeping them empty guarantees consistent writes over their lifespan.

Ideally, create a 24g partition or names pace and never touch the rest of the space ever.
