[Staples] Lexar Professional SDHC UHS-I Memory Card 32 GB - $7.99

Needed one, seems like a pretty good deal. OOS online, but price matched with Best Buy (orig. price at BB $29.99)

For anyone thinking of using these in a camera, drone, recording device, etc. note that the minimum sustained write speeds on these cards are extremely slow, only 10 MB/s despite the misleading advertising of the 95MB/s instantaneous maximums. Price is in line with the everyday price of other slow cards of similar capacity.

So it's a Class 10 (C10, U1 = minimum sequential write speed of 10MB/s) as advertised? https://en.wikipedia.org/wiki/SD_card#Class

95MB/s refers to the transfer speed not write speed, as fizikz indicated. As with everything people need to educate themselves before buying.
Would't call it extremely slow. Not optimal for 4K video recording, but 10MB/s should be enough for RAW format images on a DSLR for a non-pro user.

This card is definitely not fast, but it has a write speed faster than 10mb/s. I have the 64Gb version, and it is around 2x-30mb/s write.

It's advertised (if you click the link) as 95MB/s read and write which is highly misleading. Most people do not understand the symbols on the cards and just look at what the manufacturers shove in their face, so my post was to help those people out.

Look again - they are advertising 95 MB/s read and write with zero caveats if you actually click the link Smiling Face With Open Mouth That is typical of most manufacturers because it's what most people look at when shopping. The speed that matters for most usage is the minimum sustained write speed, denoted by the symbols on the card but never advertised by the manufacturer.

I also would definitely not be using this card in a DSLR, pro user or not - you are creating a severe bottleneck for the sake of a few dollars, it would make no sense. If that camera had a video function, it would be dropping frames unless the bitrate was extremely low. The last Sandisk 64GB U3/V30 card I purchased was double the capacity (64GB) and only $19.99.

To give you an idea of how slow that is, if you used this camera in something like a Sony RX100V (a popular point & shoot), a full buffer would take almost 4 minutes to clear. Sure it'll work, but you might miss a once in a lifetime photo to save $5.

I’m assuming this would be fine for a raspberry pi running Pi-hole?

No. This is the wrong sized card. Look for a microSD card instead

Description says it's U1 or U3 based on capacity, so sounds like the 64GB version is likely U3.

Same for me. Rfd does some redirection probably for analytics. Don't think they need to do it that way to add affiliate id
