Fast UHS-II write speeds
Even faster read speeds
Comes with UHS-II reader
Not the fastest around
The Lexar Professional 2000x 64GB SDXC UHS-II Card offers fast write and read speeds, but doesn’t offer stellar overall performance per dollar.
The Lexar Professional 2000x 64GB SDXC UHS-II Card, like many of the best SD cards, takes full advantage of the UHS-II SD standard (which you can spot by the second row of pins on the back) to push transfer speeds into the triple digits and cover a wide range of potential recording needs. Not only that, but they throw in a handy UHS-II SD card reader—a useful addition seeing as most people probably don’t have a UHS-II compatible card reader, or even know how to spot the difference. Lexar is hardly giving anything away, however, and the price reflects this decision that they’ve made for you.
Is it worth opening your wallet to Lexar in order to pay for this premium SD card? For some, it might be, but let’s take a look.
The Lexar Professional 2000x 64GB SDXC UHS-II Card comes with a black sticker with a gold trim on the side, where the advertised speed of 300 MB/s and 2000x are shown. You will also see a V90 on the label, which refers to the Video Speed Class, an SD Association standard. V90 guarantees at least 90 MB/s write speed. And if you’re curious about what exactly this card is 2000x faster than, it’s a throwback to the days of CD-ROM and their 150 KB/s drive speeds.
The Lexar Professional 2000x 64GB SDXC UHS-II Card can be used immediately after being unpackaged. When you are ready to transfer files from the card to your computer, make sure to use the included UHS-II adapter on at least a USB 3.0 port to guarantee you get the best speeds possible.
The Lexar Professional 2000x 64GB SDXC UHS-II Card makes good use of the extra headroom offered by UHS-II—we definitely saw the type of speeds we want to see out of cards in this class. There was still room for improvement, however.
In CrystalDiskMark’s 1 GiB sequential write speed test, we saw speeds of 177 MB/s across the 9 iterations of the test that we completed. Blackmagic’s Disk Speed Test was not able to produce the same results, however, and only saw 124 MB/s in its 5 GB sequential write stress test. We wonder how much variation there is between cards and if some people got luckier than we did, but this is what we were able to measure.
The Lexar Professional 2000x 64GB SDXC UHS-II Card takes full advantage of the UHS-II SD standard.
For read speeds, Lexar produced 221 MB/s speeds in CrystalDiskMark, and a healthy 249 MB/s in Blackmagic’s test. This will certainly make offloading large amounts of footage a breeze.
These speeds are definitely fast, and they will be enough to easily handle anything up to and including 6K video recording on cameras like the Panasonic Lumix S1H. The only place this card would start to struggle is with high bitrate recording modes on cameras like the Blackmagic Pocket Cinema Camera 6K, which mandates write speeds as high as 483 MB/s. You would still be able to record Apple ProRes 422 HQ at 4K, which requires only 118 MB/s.
The Lexar Professional 2000x 64GB SDXC UHS-II Card will run you about $84, based on the 90-day average price on Amazon. This is quite expensive for a 64 GB card at $1.31/GB. No other card that we tested even cracked $1 per GB. More expensive cards do exist (look at Sony’s Tough series or SanDisk’s Extreme Pro for evidence), but so do cheaper ones in this speed tier.
Lexar at least saves a decent amount of face by providing the card reader along with the card On the other hand, what if you want to buy several? What are you meant to do with all these readers?
Lexar faces the toughest competition from this Transcend card, which makes meek claims about its performance on the box, but managed to outperform the Lexar by every metric in our tests. Transcend delivered faster write and read speeds in CrystalDiskMark (186 MB/s and 250 MB/s respectively). The Transcend card also costs only $57 for the past 90 days on Amazon. The only point in Lexar’s favor here was their inclusion of the card reader. To their credit, this would be significant for users without UHS-II compatible readers currently.
Fast, but full of reservations.
The Lexar Professional 2000x 64GB SDXC UHS-II Card is certainly a fast card, but it’s not particularly inexpensive. There are cheaper, faster options worth considering if you don’t need the included UHS-II card reader.
