CamelCamelCamel.
what is the actual use case for pro plus vs standard?
also standard was cheaper on bing lee sale etc
The PRO Plus is faster than the EVO if you are using the included USB card readers for file transfers. Some other card readers also support the faster speeds but it is not universal support so you would not be able to take advantage of the faster speed with any random card reader.
But that's about it, you won't notice any real world difference for use in most devices (e.g. cameras, dashcams, switch, steam deck etc.)
yeah that is why I said what is actual use case for the pro
other than a bit faster transfer in the usb reader.
also someone mention the reader gets too hot to use safely
@eecan: Not rhetorical..
I did want to know the actual use case for the pro vs standard..
since many devices still can only make use of the standard card..
Someone answered below..
which are for those video recording devices that probably recording in 4k etc.
@pinkybrain: Note that they are using custom adapters to trick the camera into thinking the card meets the V60/v90 certification (the PRO Plus is only V30, same as the EVO). So yes, it seems like it is potentially useful for that but not out of the box and not with off the shelf components.
If it can reliably be reproduced, would be a cheap way to get around having to use V90 SD cards which are super expensive (~$800+ for 512GB) which is why it would be worth the trouble in that scenario.
@eecan: if the device needs V60/v90 then I would get officially supported one
rather than trick it.
since the card could have issue with corruption or whatever
or warranty void etc..
samsung certifiy it as v30 for a reason.
what is the speed difference between V60/v90 vs V30?
~$800+ for 512GB
that is riddiculously expensive..
can get a steam deck for that card.
@pinkybrain: It's just a minimum speed guarantee. The cards can go faster but the V rating just indicates a floor.
V30 = guaranteed minimum speed of 30MB/s.
V60 = guaranteed minimum speed of 60MB/s. These cards can usually write at 100-150 MB/s
V90 = guaranteed minimum speed of 90MB/s. These cards can usually write from 200-250 MB/s
Would I be wrong in thinking it might be slightly better than the EVO in something like a Raspberry Pi device? Or is the difference so indiscernible you wouldn't even be able to tell?
what is the actual use case for pro plus vs standard?
Pro works fine in Sony A7Siii, Panasonic GH6 and Canon R6II with the 800Mbps all-I codecs whereas the standard will error out less than 2 mins into recording :P
Are you sure about the Siii? The Pro won't even let you hit the record on a 400Mbps+ codec on a Sony A1 because it wants a V60/90 card and the Pro is only V30 rated. Just tested this myself with the 512GB PRO Plus card.
@eecan: Make sure it's a UHS-II SD Card adapter!
I have a couple 256GB PRO plus that the A7Siii will record to, but I have more than a few it wont! The Sony A7Siii is definitely the most picky of the bunch … (The GH6 works with them all, the R6ii doesn't like a couple of them)
@7ekn00: Ah didn't consider that. Have you got a link or source you can recommend for the UHS-II microSD > SD adapters? I'll buy some to retest the cards.
@eecan: I had some made up by Makerfabs as an experiment after buying a few of their M.2 to CFExpress adapters …
@7ekn00: How much did it cost to get them made and shipped? I was thinking it would be something common/off the shelf i could order!
@7ekn00: That's garbage, the PRO plus is a UHS-I card, putting it into a UHS-II adapter does absolutely nothing.
@AwesomeAndrew: Except trick the device into actually writing to the card rather than rejecting it outright ;)
But whatever, feel free to give us your vast awesome experience using these cards in high speed devices …
Pro works fine in Sony A7Siii, Panasonic GH6 and Canon R6II with the 800Mbps all-I codecs whereas the standard will error out less than 2 mins into recording :P
interesting..
so the pro plus is needed for recording videos..
what codec and resolution + bitrate/bits ?
e.g 4K or 8K h265 10 bit hdr?
800Mbps all-I codecs
This is a high detail codec for 4k@60p, 4k@120p, 8k@30p, etc All-I infers a H.264 codec with all "I-frames"
(none of the low detail P-frames that appear in H.264 and H.265 codecs, H.265 "all-I" and H.264 "all-I" are identical)
H.265 is a low bandwidth codec, most devices don't go above 250Mbps for H.265, even with 8k
800Mbps = 100MB/s write speed + audio codecs, standard cards write ~ 80-85MB/s, pro plus ~ 95-120MB/s
Yes it's an edge case as these devices typically support CFExpress Type B and UHS-II Cards ;)
(I was just curious to see if I could use microSD in these devices as I had plenty for GoPros)
someone said the reader gets too hot
and may damage the usb port plastic
Yeah the average person has NFI what is too hot. 50 C feels hot, completely harmless.
person said it could have been like 65 C
"What I found was that a 10gb file copy would make it too hot to touch easily 65c+."
hot to touch..
of course it is not scientific unless they were able to actually measure it
the person mention it here.

Wait for Prime day (6 days to go)?
I'm sure microSD cards are great for cameras and dashcams.
But if you are just using them to store valuable data or transfer it between devices with USB ports you should think about the fact that small capacity M.2 SSDs are now cheaper than the same capacity microSD cards. There's a lot of 256GB gen4 SSDs around for about $20 that are either new or have been taken out of new laptops to be swapped for bigger SSDs now they're cheap.
MicroSD cards are too small to label what's on them. Their readers overheat if worked hard, and still struggle to do much more than 100 MB/s. By comparison an external adapter with an M.2 NVMe SSD plugged into it, and it plugged into a 10 Mb/s USB port is ten times as fast, and isn't working hard enough to overheat doing that.
if someone buying microsd, it is cos they are using it in a device that needs it.
if they wanted to store data or transfer stuff, then that is another matter.
then there is
-usb flashdrive
-portable hdd / ssd
Someone buying M.2 SSDs
then they are generally using it for OS boot drive..
Does anyone know if that card reader is USB-C or just old school USB-A?
Yes, anyone would know if they looked at the image above, or went to the deal and looking at the images there.
Decent price for the PRO Plus but anyone buying these should really have a think about why they need a PRO Plus over the cheaper standard EVO Plus. In the vast majority of use cases you'll find that the PRO Plus cards provide no discernible benefit over the EVO.
