Recommendation for a USB 3, SSD drive for a Raspberry Pi 4B?

A few years back my internet connection was only 6Mbps, then there was a competing LTE based service at 70Mbps and now I have FTTH at

Not on a Pi, but I've used these on similar systems:

and they seem decent enough, although I haven't pushed the limits of USB 3 (I was mostly interested in small-block performance). I couldn't tell you what the 256GB is like, but the 32GB was fine.

Yet, you can use the SDcard to hold only the /boot partition with the kernel and firmware etc and boot to a root partition on a USB attached device. You simply specify the relevant root partition in the cmdline.txt file.

Once set up I make the SDcard /boot partition readonly to prevent any corruption of the SDcard.

I workj wit gigabyte files across the network, but I dont need to pull all of them in to my local machine before working on them. The point is can yopu process the daty aqfaster tha t eethernet?>

In may case i cant, The bottleneck is CPU not network ]

I cannot say that I have a single reliable wifi comnnectuion in this house.

Especially since today I had 5 devices hanging off two access points (visitors). Apple kit couldnt get any bandwith at all, samsung was pooor, to none and the Pi zero got slow

Its less than 10 m from the wifi points to where we were accessing them.

Frankly Wifi here sucks.,

Since it happens in background, who really cares?

Yes, you can.

Especially if the fan fails.

I come from a backround that worships at the altar of cost benefit analysis.

Running a business puts one question at the front of the queue? - "Is this actually worth doing? will the time and money invested save me time and make me money down the line?"

In so many cases the answer was 'no'

OK its emotionally satisfying to leave scorch marks on the street with all that horsepwoer, but why are you running a computer at all?

For me,. although I am a hobbyist, each project or part of my systems here has a purpose to fulfil a need.

And SSDs in my (intel) server dont fulfil any need I have, nor does the cost of rewiring the house for gibgabit .

I upgrade when I need to after agonising for months. Not because I want to fulfil some emotional need to 'be fatser'

Sure compile time on my Pi was crap. Thats why I did all the code development on a much faster intel machine.

Then I only compiled omce or twice on the pi,

Almost never. I make sure they are created on and stay on the server. Thats the whole point of having it

Never copy files from a NAS?

Nope. Why? See above. I dont have a 'NAS' I have a server which does almost everything except run the user level GUI.

ALL the data is on the server. If I need to shove it on a USB disk for travelling, that plugs into the server. No network needed.

Never do

Nope. The machine backs up to itself.

You see my client machines have little more than an operating system, on them. There is NOTHING TO BACK UP.

All the moving data is on the server and that backs itself up every night

I have code on machines out there on the internet, and that gets backed up daily, but thanks to the magic or rsync,. , there isn't a lot to back up.

Sadly when I cabled this house gigababit and cat 6 didn't exist.

Sorry to hear that. With no visitors or children, and with the main PCs connected via LAN, Wi-Fi here is no problem at all, even downloading TV programs, certain iPad software upgrades (1 GB, really?), weekly Windows Insider upgrades (3-4 GB), plenty of bandwidth remains for the 20 or so other devices. I made sure to get a good access point (NetGear R8000) and not rely on the el-cheapo box supplied by the ISP. Bandwidth is split between 2 GHz and 5 GHz.

Well I had credited you with more sense than that, so I can only assume you are being deliberate argumentative - plonk :(

These are great devices, I have several, but they are USB3.1 pen drives, not SSDs.

They are very quick (both headline large file speed, small block performance), but not quite SATA3 SSD speeds. They are much more reliable than SD cards, but they wont have the longevity of an SSD.

What about 'i have a non-critical process running in background, so I dont care whether it takes ten minutes or 30' do you dnot understand?

I had credited you with more intelligence..

If it's cabled at 5e, you might be able to get 2.5 gig, 5 gig... and possibly push to close to 10...

Not I suspect for teh cable runs I have,

In a world ruled by Microsoft, the only surprise is that anyone should be surprised by this.

Have you looked at a SATA SDD and a SATA to USB3 converter?

Or an M.2 format SSD and USB3 to M.2 adapter.

You could try to future proof yourself a bit by buying an M.2 NVMe drive and USB3.1 adapter. It will cost more but NVMe drives are just insanely fast if you ever want to connect to something else.

And to this end they built themselves a stupendous super-computer which was so amazingly intelligent that even before its data banks had been connected up it had started from "I think therefore I am" and got as far as deducing the existence of rice pudding and income tax before anyone managed to turn it off. ... Stationary mice have bigger balls.

Whatr I ant is reliable wifi in the palces where iot isnt cabled. I cant even get a decint signal 6 meters from a wifi point opn either my Pi or my Laptop.

Both end up negotaitong down to 5Mbps or less. For no god reason., signal fluctuates around 20dB for no apparent reasons. Two different wifi routers, two different clinets.

Two common factors. Linux and Broadcomm.

Have a familyt staying - apple phones simply couldn't conect. Apple laptops did. Samsung phones connected reasonably.

I mean this is utter s**te , really.
