Everything really depends on what you want to use them for. All claims of speed by mfr's and retailers are questionable as marketing hype. My wife and I recently purchased these cards for our phones. We didn't really check the Read speed, but my initial Write testing using a USB3.0 card reader on my desktop system capped the write speed at about 30MBs. However, that 30MBs is ONLY with a single large (4GB) file being copied and written sequentially. Writing a large group (2000) of small files (average 5MB each) to these cards brings the write speed to a crawl. (Note: It took just over 5 hours to write 90GB of data (music & photos) to the cards. Note: These cards come preformatted as exFat. Unfortunately, due to our phone limitations, we had to reformat them to fat32 (which slows them further). However, after reformatting, these cards work with our phones and record video and photos with no problems (so far). In my experience over the last thirty years with computers and photography I have tried numerous mfr's cards. My favorite/recent/current fastest (but yet not ridiculously expensive) is the SanDisk, UHS-3, Extreme-Pro. Even when copying large groups of small files it maintains higher speeds. You will definitely pay more for them. So the question is - do you want speed (buy the Extreme-Pro), or do you want high capacity, at a low price (buy these)? If you are a professional photographer shooting high speed (10fps) 20Mpx photos these are not the cards for you. But, if you are a pro you wouldn't be asking this question. So I am assuming you are the average user who wants a high capacity card, for a phone, or maybe point and shoot camera, I say go for it you won't be disappointed
Sorry, there was a problem. Please try again later.I checked the sandisk.com web site. For this particular card, it is explicit on read speeds as up to 48 MB/sec. It is silent on write speeds except in the disclosure fine print - "8-128GB up to 48MB/sec (320X) read speed; 200GB up to 90MB/sec (600X) read speed; write speeds lower". Generally, most brands have a slower write to read speed (the one exception I found was Samsung's Pro+, but it could also be a mis-print). However, with Class 10 certification, that's good enough for Full HD video recording. If one is downloading videos on to the memory card, then, a higher speed will be beneficial, But if one is recording video real time, this card will do. Great value with the Black Friday discounts. p/s. I haven't bought/used yet, but it's in my cart.
Sorry, there was a problem. Please try again later.I'm getting 40 read 14 write
Sorry, there was a problem. Please try again later.On the sandisk website it is listed at 48MB/s
Sorry, there was a problem. Please try again later.it lists the manufacturer part # ,, just go to sandisk and you will see it ,, as opposing to viewing other websites ,, even BB
Sorry, there was a problem. Please try again later.I ordered this, and they sent the Ultra Plus, not the Ultra. I'm guessing the Ultra is discontinued, replaced by the Plus. It's got a 90 MB/s speed rating.
Sorry, there was a problem. Please try again later.The company keeps bumping the speeds on a regular basis - NOW have a product that doesn't make me wait so long to take the next picture.
Sorry, there was a problem. Please try again later.It is 48. It says so right on the package. There is a slower speed model available but this one is 48.
Sorry, there was a problem. Please try again later.Speed is measured in megabytes per second. It varies by how much is transfer and ability of receiver to handle the speed. 48 mbps is fast. 30 mbps is reasonable. Many variables exist so a definitive answer is unknown without more data. Read your users guide for the receiver to see what the capture rate is.
Sorry, there was a problem. Please try again later.The Pixtor Brand is ONLY sold at Best Buy. They are different versions of the memory card.
