Samsung, SanDisk, and Kingston are three of the most well-known memory card brands. This article will be a comparative test of three memory cards from the above manufacturers. The memory cards participating in the test have different capacities: from 128 GB to 512 GB. Therefore, the comparison may not be entirely correct. But, in general, the speed of memory cards of the same model (the capacity of which is from 128 GB to 512 GB) does not differ much.
I bought these units at different times to use in the player. I first bought a Samsung. Then I had a player with support for two memory cards. Therefore, 128 GB from Samsung (+ one more card in the second slot) was enough. After changing the player, I had to order a memory card that would replace two cards in the old player. As a result, SanDisk was purchased for 256 GB. But over time, these 256 GB were no longer enough. I had to buy another 512 GB. For various reasons (mainly low price), the choice fell on Kingston.

Package
All reviewed memory cards are delivered in simple blister packs with a transparent window, behind which the adapter and memory card are hidden. On the front of the packages it is indicated: manufacturer, model, class, capacity, as well as the read speed (and Samsung also has write speed). On the back of packages, you can find additional information, manufacturer contacts, barcodes, a hidden authentication code (SanDisk only), and warranty information. All tested memory cards are guaranteed for ten years. Kingston has a “lifetime warranty”, but it’s really the same ten years.

Appearance
All memory cards come with an SD adapter. The adapter’s Samsung plastic feels stronger, while the Kingston’s feels less. The lock switch is the tightest on Samsung and the softest on SanDisk.

The Samsung memory card has a red and white design, the SanDisk has a red and gray design, and the Kingston is black with a stripe that changes color depending on the viewing angle. All important information is printed on the front of memory cards: manufacturer, model, capacity and recording class.

Tests
The tests were carried out using the following devices.
- Lenovo Legion 7 Laptop
- Ugreen card reader with Tronsmart adapter
- Motorola Moto G100 phone
The test was carried out using the following software.
- CrystalDiskMark v8.0 (Windows 10)
- ATTO Disk Benchmark v4.01 (Windows 10)
- Flash Memory Toolkit v2.01 (Windows 10)
- SD card test v1.9 (Android 12)
All settings are set to default. exFAT file system (Samsung SD card test tested with FAT32 and exFAT file systems).

Windows showed such a volume of monitored memory cards.
- Samsung: 128GB (119GB)
- SanDisk: 255GB (238GB)
- Kingston: 495GB (461GB)
Confuse the ability of “Kingston”. There should be 512 GB (476 GB) in there. Due to the peculiarities of the calculation, the real capacity of the disks is approximately 7% less than the declared one, while for Kingston it is 10% less.

In CrystalDiskMark, Samsung and Kingston show equally good results, but SanDisk is inferior to both in writing speed. This is to be expected given that SanDisk has a V10 record class, while Kingston and Samsung have a V30 record class. In ATTO Disk Benchmark, Kingston has the best speed, SanDisk has the worst. Flash Memory Toolkit repeats the previous test result, only sandisk is lower here even more.

I then copied the same 10 GB file to all memory cards. Kingston shows an ideal graph: the speed is stable at 82 MB / s. Samsung has the same speed, but from time to time there are reductions of up to 50%. SanDisk significantly lost to competitors – the speed almost immediately dropped to 49 MB / s and remained at this level until the end of the test.

A slightly more difficult test. I copied a data packet consisting of 20800 files with a total volume of 180GB to Kingston and SanDisk memory cards. Since Samsung has a lower capacity, I copied a data packet of 13,000 files to this card with a total volume of just over 100 GB.

On the phone, the speed of memory cards was measured using the SD Card Test app. After testing memory cards and taking screenshots, I found that Samsung card had FAT32 file system. I formatted it to exFAT and repeated the test. The read speed stayed the same, but the write speed was cut in half.

conclusion
SanDisk ordered from China almost three years ago. Samsung and Kingston shopped at local stores: Samsung more than four years ago and Kindston this year. All these memory cards work perfectly. Kingston’s capacity turned out to be lower than expected, but the speed is the highest there.
