Lexar Professional CFexpress Type-A 4.0 2TB Memory Card Review – Sony Lovers Finally Get Twice the Speed & Capacity in Type-A

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.

BENCHMARK SOFTWARE

The software in use for today’s analysis is typical of many of our reviews and consists of Crystal Disk Info, ATTO Disk Benchmark, Crystal Disk Mark, Anvil’s Storage Utilities, AJA, TxBench, as well as Sustained Disk Transfer, Temperature and True Data Transfer Rate Testing. Our selection of software allows each to build on the last and to provide validation to results already obtained.

CRYSTAL DISK INFO VER. 8.17.7 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 identifies this memory card as running in single lane PCIe 4.0, having TRIM and also shows our high temperature reached of 76°C.  Considering the small nature of this card, the high temperature is expected.

AN ADDITIONAL POINT OF INTEREST

Every so often, most recently, in fact, we get called out by a reader for testing only a card’s external performance through a card reader rather than in-camera speeds like frame rate, buffer handling, or sustained writes. And to that reader, you’re absolutely right! We’re testing the card, not the camera.

Honestly, if we focused on internal camera transfer speeds, we’d probably be replacing a few windows after tossing cameras through them in frustration. Camera data transfer performance is still terrible, and yes, I mean horrible… HORRIBLE! Why can’t I just plug my camera in and get 4GB/s transfer speeds? That would be a dream. At least the Canon R5 has solved the dreaded buffer issues that plagued older models. No more losing that once in a lifetime shot at weddings right?

That said, if we had the right equipment to measure in-camera performance directly, we absolutely would. Hope that clears things up, and thank you for reading and keeping us going strong. You’re the reason we’re still here after 17 years as the longest-running site of our kind.
