Newer things are assumed to be more relevant?

Not if you're facebook but that's a subject for another thread

Glad I stay away from social media AND Windows.. yuck.. my father uses a laptop with 10 on it, that OS is a crime against humanity..

As for new things, bought a USB stick a while ago and the damn thing came with a USB-C connector, uugh, of course no adapter was added so I had to buy one, and one extra just in case, USB-C doesn't look as sturdy as USB-A..

USB-C was designed to be more sturdy than USB Type-Micro-B.
The USB standard requires a minimum of 1,500 cycles of insertion / removal.

USB Type-C ports are rated for 10,000 insertion/removal cycles.

Is that usually before or after the connector breaks?

Yeah, I've never had bad luck with the actual USB-C connector. The cable itself, now, I think most modern cables are made poorly, but the connectors have never broken on me. I like USB-C because I don't even have to look when I connect them to the system.

Before

More devices/standards need to be made with reversibility in mind

Modern RAM / DIMM sticks is one of those that I wished would have that feature.

There's no logical reason why RAM / DIMM sticks can't be designed that way.

I have 40 terabytes of media that I am constantly moving around every time I buy more storage, with USB two.

For Christmas I am being gifted an old ass computer from the extended family that a ten year old turned his nose up at.

USB3 FINALLY!!!!!

DIMMS would probably be twice as wide in that case so nope and that's without talking about crosstalk and other rather unwanted issues. :biggrin:

Here's the pinout of DDR4 https://www.micron.com/-/media/clie...-sheet/modules/parity_rdimm/asf9c512x72pz.pdf

DDR4 has already been established. No point in crying about spilled milk.

But when DDR5 was being formalized / finalized until very recently, they could've looked at the USB group and the Type-C connector and said to themselves: hey that "Reversibility" feature is nice, maybe we should do something like that for DDR5.

They intentionally split DDR5 into A & B channels on the Left / Right side of the PMIC area.
They could've moved the I2C-I3C bus contact to the center of the contact stack and move the notch to the center or have the notch be moved to the outside of both CMD (A/B) Address pins and seperate the Address pins from the DataBus pins.

Then the CMD (A/B) & PMIC power feed pins could be in the center prong while the Data Bus be on the outter prongs.

But they chose not to go that route for some reason, probably sunk cost reasons.

^^ Designing crowded PCB's is really hard, you can't just move pin assignements around because it would come in handy, again, you can have issues with crosstalk and other palaver, and yes cost is indeed something they are trying to keep as low as possible so adding another layer to the PCB for example to make something possible might just be too exensive.

It's just 1x Contact pin
=:::

I'm sure an engineer can be spared.

I'd leave the rest of the pins where they are =D

Just move the alignment notches =D

Santaman · Dec 19, 2021

Well maybe they simply don't want it to be handy? :biggrin:

That could always be one of the reasons, who knows what these standard bodies think.

Marc · Dec 21, 2021

sometimes it just doesn't pay to restart.

Rebooted my server today to change a configuration only to have my 2TB WD drive decide to shit it's self without warning.

Nothing that can't easily be replaced just some backups and a few LXC's but still a pain cos now I have to replace the drive and find one that isn't shitty magnetic recording. Replacing it with an SSD would be nice but not affordable at the moment. Can get a 4TB spinning rust for half the price of 2TB SSD (no NVMe support in the server) Though I could move the 2TB drive from my workstation into the server and put a 1TB SSD in it's place.

Only thing is that drive isn't a spring chicken with 21043 POH and current read error rate is 200 though crystal disk info says the drive is still good.

The drive has been spinning away since May 2014 so it's not new by any stretch of the imagination and more much of it's life it ran 24/7 because I don't shut the server down).

Santaman · Dec 21, 2021

Hmm.. personally I would buy a new drive for the server, spinning rust would do fine , using another old(er) drive I would probably not do, SMART data is nice and all but can change faster than you can scream headcrash.

Gingerbread Demon · Dec 21, 2021

Have you tried retailers in Melbourne or wherever you are like PC Case Gear or such, they have a wide selection of regular hard drives.

Oh frak forgot you are in Canada aren't you?...... Well try Best Buy

It was mainly used for temp storage and backups while I was building the LXCs and VMs so I didn't waste writes on my SSDs and I just hadn't move the things to the faster storage (done enough of that moving from ESXi to Proxmox).

So even I move the old spinning rust from my desktop to the server it won't be super critical because they'll be backuped from there to an external (which probably be replaced in the next few months - it's hours are getting high).

guess it will come down to how much of a tight wad I am. Though everything that's important has at least two copies and off-site.

Santaman · Dec 22, 2021

If it isn't really critical then indeed you can use the old drive.
I don't use external drives as a backup device, they're a transfer device, for backups I use other computers.. had one external drive fail a few years ago, pulled the drive out which was still okay, it now is the internal drive of a frankenmachine. :biggrin:
