[Older Version] SanDisk 64GB Ultra MicroSDXC UHS-I Memory Card with Adapter - 100MB/s, C10, U1, Full HD, A1, Micro SD Card - SDSQUAR-064G-GN6MA

Still works, really reliable, huge capacity have one of each generation of Pokémon games(Arceus, Shield, Violet, let's go eevee, diamond), have both breath of the wild tears of the kingdom, animal crossing new horizons and its DLC, skyrim, monster hunter rise, I could go on so many games downloaded to my switch at once and I STILL have about 30GB left. WORTH every penny

working as advertised, delivering in all conditions

Solid, fast, unit - as described.

This lasted I don't know how many years, well from purchase to just last year when I went to load my songs back on to it and it said there was no space on it.No clue what happened but definitely had gotten my money worth.

200 Giga Bytes SanDisk Ultra micro SDX UHS-1 A1 U1 SDSQUAR-200G-GN6MARead and write test on usb3 with usb3 card reader. FAST Formatted on the micro SD card is NTFS cluster size=default.Established and first noted, is that the equipment used to test, by far supersedes the capability of the item being tested.Major and primary type files in the folder used for the test are strictly video files of different extensions, different bulk size's,and different in frame size's.This test is not intended to find out transfer and write speed rates for teeny tiny mega files, IE note pad, word doc's, officedoc's small photos, mp3 etc.The Read test folder HBPVR size=28,993,187,364 bytes, Read speed=89.3 to 90.6 MB's constant=yes, dropped down on read speed=yes=one occurrence for approx. 2.5 seconds @ 70MB's. It is noted that during the full 28.9 GB data read test, the card core temperature reached 139 F. (the read test was non stop)The Read test full folder was copied onto a solid state drive and then named the same HBPVR-2, The card ,with the reader was ejected and the laptop on a/c plug in was shut down and restarted. It is noted, settings on the laptop were set to high performance during reading and writing test's. Also original folder will be left on the card whilst accomplishing the write test which may perhaps give an idea of how fast the write goes as the card gets fuller toward the 60GByts of data.The Write folder HBPVR-2 size=28,993,187,364 bytes, A burst write speed off the bat 49MB's for about 2.5 seconds then calmed down to a consistent 29.1- 33.5MB's throughout the write but with a few lower and higher write spikes for a (very short time) during the total write time, -was 14 minutes and 50 seconds, which averaged out to an 32.54MB's with an internal temperature 154 F at the core, 138 F at the mid body, and 132 F at the outer edge end of the card. (the write test was non stop)Phone APP expedite well? show me an application that will need to burst open 89.3 megabytes of data in a second to get going on your phone screen? Though perhaps here would be where the small file size read test would help. However in summary the card is developed as A1, but also consider in fairness your phone micro SD card reader capable of at least reading at these speeds? If not tested, then one really wouldn't be able to blame the card as fault. Is your phone processor capable to execute a single phone application of 89.3 megabytes of data in a single second?If not tested, then one really wouldn't be able to blame the card as fault. One might want to install the card in the phone and set up the phone into a USB 3 port and read and write to the card this should perhaps give an understand how fast the phone may be accessing or communicating with the card.Full HD= This card should by far exceed 1920x1080 with video and audio capturing at high bit rate.DCI 4K (native resolution) is 4096 × 2160 1.90:1 (256:135) 8,847,360 mega pixel frame size. Well one would have to be a bit"" carefulwhen\ or while wanting to achieve this type of video capture using this card, as its capabilities are no slower thanwriting at 29.1 mega bytes per second, thus one would have to configure their frame size, bit rates, both audio and video,. As long as the overallconfigured calculations don't exceed the write speed you should be successful to capture 4k on this card.I was not able to achieve 100MB/s (read) speed, thus 4 star.

it work great

Gracias

Perfect price. Needed a small SD card to put in my Roku ultra devices. This now prevents the constant errors from coming up then I'm out of memory. I hardly even had any streaming channels installed on the devices. I've been using this with my Roku for the past month and it's been working perfectly.
