Lexar Professional 2000x SDXC UHS-II Card Review (64GB)

A little over a year ago we were able to take a close look at a new breed of SD cards thanks to SanDisk releasing the world’s first UHS-II SD card, the SanDisk Extreme Pro. The standard was so new, besides the Fujifilm XT-1, no other camera even supported the form factor at the time. In September Lexar finally released a product to compete against it, but not only did it compete, it took the crown as the fastest SD card in the market. Today, we get to put the Lexar Professional 2000x SDXC UHS-II through its paces and see how it performs.

WHAT IS UHS-II?

For those who do not know what UHS-II is, it is the latest adaptation of SD card standards which, through the addition of another row of contact points, allows for increased bandwidth over older SD cards. Right now, however, even a year after its release there aren’t many cameras that support this new interface. So, you may be wondering what’s the point in buying this over a cheaper UHS-I card? Well, it all comes down to speed. Just like the SanDisk Extreme Pro, this Lexar Professional card is not your ordinary storage media, it can deliver astonishing read speeds of up to 300MB/s!

For those with HDD RAID 0 arrays or SSDs, you can utilize this card’s read speed to help expedite your workflow. With some cameras’ RAW files reaching 40-50MB in size as well as 3D and 4K video being storage hogs, having reads speeds of up to 300MB/s off your storage media can substantially better your workflow or user experience.

Okay, so now that you understand the use for such fast storage we are sure you are wondering about compatibility, especially since only a handful of cameras actually support the interface natively today. Well, luckily UHS-II media is backwards compatible with UHS-I and non-UHS devices, so you can go out and use this in almost any camera you want and still benefit from fast read speeds.

PACKAGING, PRICE, SPECIFICATIONS, AND AVAILABILITY

As just mentioned the Lexar Professional 2000x is a SDXC UHS-II storage device that is capable of read speeds of up to 300MB/s. It also carries a U3 rating, which means that it has a minimum write speeds of at least 30MB/s, but as you will soon see in our benchmarking, it is much greater than that. It is available now in capacities of 32GB and 64GB for $59.99 and $99.99 respectively.  Finally, this card is covered by a limited lifetime warranty.

The packaging is standard of their product line. On the front it states not only the capacity and speeds, but that it comes with a UHS-II card reader, which is USB 3.0. It also includes a media recovery software called Image Rescue to aid in the recovery of your accidentally deleted photos and videos, even if your SD card is corrupted.

FLASH MEDIA TEST PROTOCOL

Lexar Professional 2000x SDXC UHS-II 64GB Card ReaderTo connect the SDXC card to our computer we will be utilizing the included USB 3.0 UHS-II card reader. In order to test the rated speeds of the card we choose to use a few popular synthetic benchmarks which include ATTO, CrystalDiskMark, and Anvil Storage Utilities Professional. Not only are we going to use these benchmarks, we are going to run a comparison against other cards we have on hand and test in a real world use scenario. This should give us enough to confirm the rated specs and give us a more in-depth view on how it performs.

    There is a big difference for maximum IOPS compared to the fastest SanDisk Extreme.

    Anything smaller than 32KB per transfer is much slower with the Lexar. The 4K R/W performance gap is 2.9/26.5 -vs- 57.5/143.7 MB/s (Lexar -vs- SanDisk). 256KB sequential R/W speed favours the Lexar but real world cameras don’t seem to use the pattern (more like 32KB ?). The SanDisk low write latency is great, however the small read performance and higher queue depths are not optimised.

    • When it comes to cameras all that matters is large block sequential speeds. Small block performance is useless.

      • tygrus

        If you are right then why does the SanDisk beat the Lexar when in a camera, albeit camera not UHS-2 compatible, Queue=1? The high seq benchmark has little indication of real world in camera performance.

      • Well, we didn’t compare the SanDisk UHS-II card. That was against an older UHS-I card. Also, the numbers on the chart are rounded. The SanDisk on the chart = 7.43s while the Lexar = 7.64s average…not really much of a difference, but you can see that after rounding the SanDisk = 7 seconds while the Lexar – 8 seconds.

        Even if we did compare the SanDisk UHS-II card, we would still be comparing them in a non-UHS-II camera and they would be running at UHS-I speeds. You can’t really show how much better one card vs another is in that bench when they are actually capable of so much more speed. I just included it to show that there weren’t any inherent slow down issues that I have seen with other cards in the past. Essentially I look at that graph and conclude that all perform practically the same. Unless one takes significantly longer, varying 1-2 frames doesn’t really matter.
