<p>Hi Richard,</p>
<p>So you're happy with the RPi4 as your daily use machine? I'm
seriously considering this to replace my aging i3 All-in-one. <br>
</p>
<p>Cheers</p>
<p>Andrew<br>

<div>I use RPi 4 with dual monitors as my main desktop machine
daily. I use a Samsung Portable SSD T5 500GB, bought from
PBtech just about as soon as RPi4 came out. The was possibly
not the cheapest solution but hardware wise its plug and play
and readily available. I reckoned that if I ever needed more
space then SSD's would have reduced in price. Creating and
enabling a swap partition prevents the pi locking up when
Firefox or Chromium have too many active tabs. The SSD is just
used as my home drive as USB booting from SSD arrived after I
had my setup all working. Let me know if you would like some
measurements done.</div>

</div>
<div>Looking at the PBTech web site it looks as though the T5
has been replaced by T7.<br>

<div>I moved to Pi after blowing up my laptop motherboard using
a new chinese usb supply on a usb connected arduino nano. The
supply was well designed but was manufactured with a sticky
foam pad bridging the safety barrier. Consequently I bought a
new laptop motherboard, rpi, and a HV insulation tester! If
I'm ever daft enough to repeat the mistake I'm hoping to just
replace the Pi.<br>

<div>Would you mind letting us know what SSD you ended up
getting and from where? I've looked into this briefly
and I couldn't seem to figure out how to find one of the
Pi compatible ones known to work.</div>

<p>And for something more aligned to the list, I
replaced my Windows Laptop after I discovered my
Raspberry Pi 400 compiled the same C source in ~40%
of the time. So I went to the New Years sales and
$1100 later the Raspberry Pi is still quicker.</p>
<p>To reward it for its efforts I now have the Pi
booting from a $69 USB3 SSD rather than usual uSD
card. It now reads disk at 300MB/s.</p>
<p>It is much more capable than expected.</p>
