What? Is a 200GB MicroSD card too much storage space?
The 128GB capacity cards are plentiful, and one good card worth considering is the Samsung EVO 128GB microsd. It is compatible with Linux, it offers decent read and write speeds, and it features the quality we expect from Samsung.
The typical packaging you would expect. Includes the microsd card and one microsd-to-SD adapter.
The Card Itself
This is a UHS-1 Class 10 card. I tested the card in Linux Mint 17.3 using the Disks benchmark, and here is the result:
The front of the package claimed “up to 48 MB/s transfer speed with UHS-1,” but cards rarely meet their advertised claims. That is why we see so many asterisks “*” on the packaging. This card is no exception. Despite repeating the benchmarks, the 32/8 MB/s read/write speeds were consistent in Linux Mint 17.3. This is actually fine for everyday usage, but it still feels disappointing when the package text makes claims that lead me to believe in better results. On the bright side, the read/write results seen in the graph were consistent, unlike the SanDisk 200G card that began with fast write results but then dropped to slower write speeds over time.
By contrast, CrystalDiskMark 5.1.2 (Windows 7) reported better results closer to the advertised 48 MB/s speed (sequential, of course):
In this case, the packaging is closer to the truth, which must mean a difference in benchmarks. Not certain why those differences exist, but this is still a good card that retains data well. I have not encountered any corrupted files — providing that the card was also safely ejected from the system first.
Will the Samsung EVO 128G Work with the PlayStation Portable?
Connecting the 128G microsd to the PSP using a MicroSD-to-Memory Stick adapter is possible, but the PSP will not use the card. The PSP will recognize the card and format it, but if you try to then connect the card to a computer in order to transfer files, you will be prompted with this dialog in Linux Mint 17.3:
Formatting the card in Linux and then inserting it into the PSP does not work either. This is the same situation when testing the PSP with the SanDisk 200G microsd. Apparently, the PSP is not compatible with 128+ GB cards, and this is strange because two 64G microsd cards in a dual adapter work perfectly by giving the PSP 128G of unformatted storage space (119GB after formatting).
This is another good microsd card for everyday use. As long as you do not need fast, 80+ MB/s write speeds, then this should fill the need at an average cost for its capacity. So far, this card is reliable, compatible with a wide range of devices when formatted as FAT32, and, best of all, compatible with Linux.
