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

Any recommendation for an SSD drive for a Raspberry Pi 4B? Must be
USB-3, of course, but capacity not critical. Seems that 256 GB is
likely the sweet spot for value per GB.
Thanks!

Samsung or SanDisk are my recommendation. The only risk is they will stop making such small sizes before long.

Yes, brands I would trust as well. Thanks. I was hoping that someone might have actually used one of the USB-3/SSD drives!

I only need about 40GB for my SSD to boot from. And store its programs.
Data? All on a networked server running big spinning rust. The switch is only 100Mbps so whats the pont of making that disk SSD?
Anyway its well fast enough.

Quite a few devices on my network run at gigabit speeds, as does the RPi-4B. Two reasons for going SSD: speed now a full-speed USB 3 port is available, better life than an SD card (larger capacity, designed for more write cycles [perhaps]).
The more I think about it, having the SSD as the system boot device might be a good idea as well. Seems like that should be easy at least with the 3B+, and perhaps therefore the 4B.

I don't like the idea of the one-time programming required for earlier models, though.

yes, but do they in fact NEED to?
My router and my desktop both have gigabit capabiliy but really, what IS the point when internet is only 7Mbps?
And the house is wired CAT5 anyway.

Thats a bit like saying the reason to drive at 150mph is that the new M1 can handle it.
It is good to have fast booting on a desktop, that does get booted fairly often
(Of course the whole rationale behind systemd was fast *server* booting, which shows you what a swine poettering really is, but I digress...)
Mainly my complaint is that technology for the sake of it is really a waste of money and effort.
So much of it doesnt solve an existing problem and introduces new ones.
Take 'let's not wire stuff up: Let's use wireless"
Now all that happens is speeds are down, because interference is up and the whole spectrum is a mess, and connectivity is massively unreliable.

Definitely a good idea but doesn't work yet. They're working on updates that will enable net boot and usb boot on the Pi4. You could easily boot a minimal image from sd card and move the root file system to the ssd, though.

You are it seems ot of date. USB boot already exists. Albeit a bit of a hack

Which makes one wonder if not that article was written before the 4 existed. And if it applies.
I think I read that article at least a month before the relase of the pi4

First sentence, in bold: "USB boot is available on the Raspberry Pi 3B, 3B+, 3A+ and Raspberry Pi 2B v1.2 models only." So not on the Pi4, yet.

I assumed that was because the article predated the 4.
It would be strange to remove a feature from the 4 that worked on the later 3s...
...But I see that, yes, the boot stuff for the pi 4 is COMPLETELY different.

Yes, I'd noted it was "in progress".

I'm often working with 100-200 MB files across the network, so the gigabit Ethernet is justified.
My feeling, and reports, show a significant speed gain (operational speed - time is precious) from having as fast a disk as is (within reason) possible.
Wi-Fi is a major boon here, and in many other places. Phones and tablets, and not having to rewire the house with whatever UTP cable. Not to say it shouldn't be done carefully, or that's it's appropriate in all circumstances. What suits me, won't suit others!

For the Pi, its not the headline large sequential read and write speed that's important, but the 4K random access reads and writes. Theses are vastly faster on an SSD than a hard disk, even with a USB2 interface, and make a lot of difference when used as a boot disk.
Running a big apt update, which does a lot of disc reads and writes, can
be 3x to 5x faster with an SSD.
You can never have to much fast!

The internet isn't everything! Do you never transfer files between machines within your network? Never copy files from a NAS? Never do backups to another machine?
