Samsung P9 Express 256GB microSD Express Card Review – A Performance Value Compromise

TSSDR TEST BENCH AND PROTOCOL

SSD testing at TSSDR differs slightly, depending on whether we are looking at consumer or enterprise storage media. Our newest system is comprised of the latest Intel Ultra 9 CPU set into the ASUS Z890 ProArt Creator motherboard with 64GB of Corsair Platinum Dominator DDR5-6400 memory.  For Creators, this motherboard contains two Thunderbolt 5 (80Gbps), a Thunderbolt 4 (40Gbps) and a USB 3.2 2×2 (20Gbps) Type-C port, something no other has done to date.

For this Test Bench, there are just a few standard performance tweaks and our new ProArt Z890 Test Bench is set at 5.4GHz while the 64GB Corsair Dominator Platinum DDR5-6400 memory settled in at 6600MHz.

MICROSDXS EXPRESS CARD READER

For our testing today, we are using a Realtek 9211XD SD7.1 Express card reader which bridges the card to Type-C USB where it travels via PCIe 3.0 x1 (single lane).  As the original card reader is SD compatible, we were also provided with a microSDXC Express adapter as a typical UHS-II SD/microSD adapter does not work.

BENCHMARK SOFTWARE

The software in use for today’s analysis is typical of many of our reviews and consists of ATTO Disk Benchmark, Crystal Disk Info, Crystal Disk Mark, Anvil’s Storage Utilities, and TxBench, as well as testing utilizing Nintendo Switch 2 comprising of transferring data to and from the media and game load times while running MarioKart from the Samsung P9 Express card.

CRYSTAL DISK INFO VER. 9.6.0 X64

Crystal Disk Info is a great tool for displaying the characteristics and health of storage devices. It displays everything from temperatures, the number of hours the device has been powered, and even to the extent of informing you of the firmware of the device.

Crystal DiskInfo validates that our Samsung P9 Express microSD Express Card is operating within the NVMe interface which means it is using the PCIe 3.0 lane and follows the NVMe 1.3 standard. It is also interesting to note that these cards are TRIM compatible, whereas a normal UHS -I/II card does not even show up in this software.
