overkill? fast drives, cheap machines, and maxing out usb 3.1
Posted by: mattkime

I recently discovered that the sd card in my raspberry pi 4 (4GB) is slow. SD cards, generally speaking, are slow. Sure, its basically a toy computer but who wants to leave easy performance gains on the table? A little reading later and I have a $85 500GB SSD drive and a $24 USB-C 10Gbps enclosure in my cart. The ssd should be 4x faster than the ssd card.

What about power? Can my pi power this thing? Probably not! Time for a $39 powered usb-c hub

Now I realize I just spent $150 adding a drive to a computer that cost me $55 to start with.

Now I'm wondering if the drive is overkill. Based on the page I linked to above - the drive provides more speed than other ssds even though on paper it seems like many ssd drives should easily exceed the speed of the pi's usb 3.1 bus.

Seems like they should release a Raspberry Pi with an SSD interface on it.

Not to worry. Allow me to introduce you do a thing I like to call, "photography." No, I meant, "old cars."

It has been called a "hamster."

$10 at the pet store.

$40 cage, $20 for bedding, $40 for a year of food, $20 for a wheel, $40 for a ball, $200 for a habitrail, etc. Like deckeda said, the same thing can happen with a lot of other hobbies.

Nah, of course you need a $45 Pi case with internal M.2 SSD support

Saw that, not impressed by the tiny tiny usb cable. I guess it works if you really need it all in the same case.

Speed might be limited by the pi.
