SanDisk Breaks Storage Record With 400GB microSD Card

[Dima007]

SanDisk is offering a new 400GB microSD card, a breakthrough that would make it the largest microSD currently on the market. SanDisk, which is owned by Western Digital, hasn’t revealed details beyond stating that the capacity breakthrough was the result of WD “leveraging its proprietary memory technology and design and production processes that allow for more bits per die.” Western Digital set the previous record two years ago, when it launched a 200GB microSD card.

The speed appears to come with a tradeoff. SanDisk trumpets its A1 speed rating, saying: “Rated A1, the SanDisk Ultra® microSD card is optimized for apps, delivering faster app launch and performance that provides a better smartphone experience.”

They should repair their 16 gb cards first. " Safely remove" almost always shows " Drive is being used " ?!?!

I'm using SD card from this company for many years, this is the first time I've heard about this issue. Are you sure that the cause of said issue is from SD card itself?
Maybe something actually accessing your SD card like your AV's.

Blimey, that's a lot of storage for an sd card, it will probably cost and arm and a leg

Quite a few months ago i had this issue with my external hard drive and i got it sorted by asking good old Mr Google, the steps were similar to this video and it worked for me so perhaps you should try it. I doubt it was the hard drive or indeed your SD card but more likely to be a pc problem. Anyway, here is the link if you want to try it

The issue is probably caused by security or optimizer software locking the device... Download some unlocker software and see who is locking the disk.

I would search for solutions, BUT, my Sony 16 gb ALWAYS EJECTS SAFELY.. So, Sorry, its the Sandisk!! & other Sandisks too..(we have 2 or 3)

That has nothing to do with brand of SD card, something (some program) is using it. Sometimes the AV keeps scanning USB files and makes removing them a hassle.

Try this code, copy it to a text file and save as .bat.

@echo off
@cls

set tempfile="%TEMP%\diskscrp.dsk"

echo.
echo   === Disk removal tool ===
echo.
echo   Select the disk volume number
echo   (if the disk has multiple volumes, select any of them)
echo.
echo list volume | diskpart | findstr /C:Volume /C:---
echo.
set /p volume="   Selected volume: "
echo.

echo select volume %volume% >>%tempfile%
echo offline disk >>%tempfile%
echo online disk >>%tempfile%

diskpart /s %tempfile% | findstr /C:"not valid"

if "%ERRORLEVEL%"=="1" (
  echo   Disk has been unlocked successfully.  Try to safely remove it now.
)

del /F %tempfile%

this usually works for my 1TB WD portable hdd & 32 GB HP flash drive
Edit: I forgot to mention run it as Admin.
