I have purchased five or six of the Samsung Pro Plus micro SDXC cards in the past 2 years, in sizes ranging from 128 to 512. When I test these on USB C 3.0 card readers-I have two different brand card readers- I have never had a single write speed below 79 mb/s, Which makes these consistently faster than some of my V60 cards. In the case of the 512gb card specifically, I've had write speeds consistently over 105 mb/s. The Reed speeds tend to be around 110 to 130 mb/s in my tests. An incredibly strong performance given the price of the cards.For the price, these cannot be beat. Even for my highest bit rate Canon and Panasonic consumer hybrid bodies, I can use these cards and not worry about dropping frames.

I picked one of these up to double the storage of my Steam Deck without installing a new SSD. I wanted something that was inexpensive, high quality, fast enough to load games from, and had the capacity to hold 10-20 games.I've been a longtime Samsung memory customer dating back to their 2.5" IDE SSDs before NVMe SSDs were a thing. I built my desktop using a couple of their NVMe SSDs and wanted the same reliability with my Deck. My Nikon camera also has a Samsung memory card so I know this should perform well.It has served my Deck nicely for almost a year without having issues. Games quickly install and load. I don't really notice a difference between a game installed on the memory card and internally. That's mainly thanks to SteamOS's optimizations.

Still, I think it's a testament to the memory card that I have used for about a year, constantly uninstalling and installing games, without any issues. Most other memory cards I heavily use end of getting corrupted by now.I highly recommend this card for anyone looking to add reliable, fast storage to their Steam Deck without breaking the bank or going through the trouble of installing a new SSD.

For the price, you won't find a better microSD and USB adapter with reputable name like Samsung.On top of the high quality microSD, the USB adapter is by far the best adapter I have ever received with a SD, or microSD card. This isn't a cheap piece of plastic, it's a fully shielded USB 3.0 adapter. When comparing it to my old "LEXAR" adapter (which is finicky and works only if you insert it half-way), it is clear that the Samsung adapter is made with much higher standards.High-speed transfers, recognized across multiple Operating Systems. I have confirmed it to work Out of The Box with :-Debian Linux (Kali, RecalBox, and RetroPie)-Mac OSX-Windows 11
I wanted Windows as a secondary OS on my new OLED Steam Deck but was afraid the Windows installer would somehow wreck my Steam OS install if I attempted to put it on the internal drive...My solution?This nifty little pro card! It has beefy specs with plenty of write speed (a rarity among most SD cards) and doesn't seem to suffer from any slow downs once you start filling it up! I imaged Windows To Go on this card, inserted it into my Deck and it booted into the Windows initial setup perfectly!The OS didn't have sort of slow loading, weird hang-ups or "lag" typical of most portable installs, which really speaks well for the quality of this card, more so given how resource-hungry Windows can be!Overall an amazing card, especially for the $30 (512GB) sale price I ... MoreI wanted Windows as a secondary OS on my new OLED Steam Deck but was afraid the Windows installer would somehow wreck my Steam OS install if I attempted to put it on the internal drive...My solution?This nifty little pro card!

To help you decide which one to purchase, let me break it down for you --Pro Plus only costs a dollar more compared to EVO Plus at the time of purchase, Pro Plus has a Max Read Speed of 180mbps and Max Write Speed of 130mbps. While EVO Plus have a Max Read Speed of 130mbps and Max Write Speed of 100mbps.The Tech Specs of Samsung Pro Plus Micro SDXC are comparably the same with SandDisk Extreme Plus (A2, UHS-I, C10, U3, V30).SD is short for Secure Digital. SDHC or "High Capacity" cards range from 4GB to 32GB. SDXC or "Extended Capacity" cards go from 64GB up to 1TB.Value: ExcellentQuality: ExcellentEase of Use: ExcellentHighly Recommend, 2 Thumbs up!
These were on sale, and I had some rewards built up that were to expire. I purchased one of the first usb drives for $200 and it was under 2 gigs i guess and not that small. I know that SD cards have gotten cheaper, but I may place more value on them for reasons most would not. I have never had one as big as 256, and my new Air 3 was in need. On sale for under $20 and I was able to buy 3 for about $10 with using my rewards. The Air 3 uses about a gig of space per minute of recording. In the past I had to pull the card, upload it to the computer, and basically wait. Now I have 1 for the controller and 2 to swap from the drone. The cards seem to be top notch, and they are faster than I had used before.
I did a good bit of research comparing the Samsung to the Sandisk and found no logical clear winner between the two. It seems that the Sandisk is a micro fraction faster than the Samsung but the Samsung is more reliable. I also read that the tiny difference in speed has no impact on anything.I bought three of these to use in my GoPro and have found them to be excellent. I have had no reliability issues nor have I had any problem with read/write speed. I have recorded hours at 5k with no issues whatsoever.I recommend this product because of the fair price and the quality.
I currently have the 128 GB Samsung Pro Plus in constant use with my new-ish Hp Envy 17.3' 12th Gen Intel Cpu Laptop's integrated standard sized SD Card reader with the micro SD card size to standard SD card size adapter included with this micro SD card and I am very very VERY impressed with the noticeable increase in performance compared to the prior generation of this card. The prior model generation that I used was I believe 160MB reads and 120MB writes and this one that is the newest model for this year 2023 which increases the speed to 180MB reads and 130MB does perform faster and I do notice it when I use my software installs from the just fantastic micro SD card.If you have a newer-ish laptop that has a working SD card slot and the latest drivers for the SD ... MoreI currently have the 128 GB Samsung Pro Plus in constant use with my new-ish Hp Envy 17.3' 12th Gen Intel Cpu Laptop's integrated standard sized SD Card reader with the micro SD card size to standard SD card size adapter included with this micro SD card and I am very very VERY impressed with the noticeable increase in performance compared to the prior generation of this card.

I love this Samsung microSD card. It performs very well for my need. I use it as the second staorage for my smartphone in daily use. In addition to provide me extra memory spaces for taking photos, I can download video files online for my personal view. It is very important because I would like to save those files for later reviews. Another good advantage of this order also including a full-size SD adapter so that I can put the microSD card in it and bring it to my labtop or desktop computer to do file management use. The 512GB size is perfect and I have plenty of room to save files. This compact size card is great and I wouldn't mind to purchase additional pieces as spare in case I need it.
