Samsung EVO Select

Samsung is most noted as a smartphone and electronics manufacturer, but the company also makes proprietary microSD cards for its smartphones. While this does not automatically mean the best experience, Samsung’s EVO Select memory card is perfect for the Galaxy S9.

Samsung EVO Select

Inter-brand compatibility is nice, but what we really like about the EVO Select is its steady mix of data speed performance and affordability. With a 90MB/s write speed, this Samsung microSD is better at handling intensive data writing tasks compared to rivals. When you want to transfer files from the EVO Select, its 100MB/s read speed will get the job done efficiently.

As a Class 10 cards with UHS 3 support, the EVO Select delivers a level of core performance to suit most Samsung Galaxy S9 users, even those who use the camera at an enthusiast level. Whether recording in 1080p or taking succession shots on your smartphone, this card handles the load.

SanDisk Extreme

SanDisk is the leading name in the memory card market and is notable as the inventor of both the compact flash card and SD card.

The company’s Extreme is the mid-range of its core series, sitting between the budget Ultra and elite-grade Extreme Pro. We think the Extreme cuts a nice balance by offering excellent performance at a good price.

SanDisk Extreme

It’s an ideal candidate as a microSD card for the Samsung Galaxy S9 because it is such a good all-rounder. If you like to hold the camera shutter down on your smartphone, the SanDisk Extreme is a good choice because its (up to) 90MB/s write speed allows superfast data processing. That write performance also makes taking high-resolution videos a breeze.

Read speeds are arguably more important to smartphone users, who want to move files quickly between devices and destinations. With up to 160MB/s read speed, the SanDisk Extreme makes file processing fast and efficient.

Kingston Canvas React

While the SanDisk Extreme and Samsung EVO Select represent good value for money, the Kingston Canvas React is a bona fide bargain.

It may not be as powerful as those rivals, but for a majority of Samsung Galaxy S9 users, this is all the microSD card you will ever need. Most smartphone users want decent data performance and not pro-level abilities, so the Canvas React fits the bill.

Despite costing under $10 (32GB model), Kingston is still offering an excellent amount of data transfer speed. For example, the Canvas React can deliver a write speed up to 80MB/s. While that figure is unlikely under most scenarios, this Class 10 memory card can deliver consistent data writing in most situations.

Thanks to its UHS-I U3 speed rating, the Canvas React can offer read speeds up to 100MB/s, allowing file transfers to happen in snap. For Android devices like the Galaxy S9, Kingston’s card provides A1 performance for faster app launches.

PNY U3 Pro Elite

PNY is one of the leaders in the memory card market and the company’s U3 Pro Elite microSD rivals the Samsung EVO Select and SanDisk Extreme in terms of performance. However, it is admittedly more expensive than those rivals. Still, for Galaxy S9 owners, the U3 Pro Elite will be more than enough for most scenarios.

PNY U3 Pro Elite

We would describe this as supreme performance, with a write speed of up to 90MB/s. Like the Samsung and SanDisk above, this is enough data capability for even pro photographers who use their S9 for shot-to-shot bursts and high-def video recording. PNY backs up this write speed with up to 95MB/s reading, allowing files to transfer to a PC in seconds.

Whether you are transferring videos, music, photos, or files, the PNY U3 Pro Elite is an excellent choice. It is also a bomb-proof card that should last you for years without any signs of data corruption.

Gigastone Prime 600X

Gigastone is not a well-known name in the memory market, but the company is gaining a good reputation on Amazon. That’s large because its cards deliver excellent performance and are hugely affordable compared to most rivals.

For example, a 128GB version of the Prime 600X microSD card is available for around $15.

Gigastone Prime 600X

What’s interesting about Gigastone cards is the company clearly bases its design on SanDisk memory cards. That’s ok we guess as no one cares what a microSD card looks like, but for full disclosure, we believe SanDisk cards are better than Gigastone so don’t think they are the same just based on looks.

All that said, the Gigastone Prime 600X is an excellent microSD card for your Samsung Galaxy S9. Its 90MB/s data speed ratings will allow for most camera tasks and will handle general data file management and app opening with ease.
