Review on 💾 128GB Lexar Professional 1000x SDXC UHS-II Card by Carlos Massey

I have a Panasonic DMC-LX100 that can record 4K 30p video at 100Mbps and sometimes the recording stopped with an error saying, that the recording speed cards are not supported high. This was done with an Elite Performance SDXC 64GB UHS-1 90MB/s card for PNY 28, so I have a 128GB 150MB/s UHS-3 Lexar SDXC card and it works great for 4K 30p. UHS-1 guarantees a minimum write speed of 10MB/s, while UHS-3 has a minimum write speed of 30MB/s, which is probably where the UHS-1 card falls short of 4K. I unofficially tested the Lexar by taking four 15-minute recordings in a row. The 4K and LX100 recordings got very hot, but there wasn't a single bug. The Lexar card also took 100 12-megapixel shots in high-speed 11fps burst mode before slowing down. The PNY can take 95 shots before it slows down, so it's not a huge difference for photos, but I don't want to risk using PNY for video and suddenly stopping recording 4K. Running Windows 7 with an OCZ Vertex 4 SSD and a Transcend USB 3.0 card reader, I copied a 6.5GB file to and from a Lexar card and the average write speed to the card was around 60-65MB/s when copying from the card was 87 -90 MB. /With. Overall, this Lexar Pro card seems solid for 4K capture, and I'll update this review if I run into any issues. By the way, it annoys me that while most cameras format SD cards in exFAT format, which no longer has the 4GB file size limitation of FAT32, it still splits a 30 minute clip into 6 separate 4GB files becomes. . I want to be able to record videos in one huge file. Also, most camcorders limit video recording to 30 minutes due to some EU taxes on camcorders, but being in the US I don't see why we have to stick to that limit. Luckily, the US version of the upcoming Panasonic DMC-FZ2500 4K camera doesn't seem to have a recording length limit and can even support files up to 96GB with an SDXC card. I can't wait to find out if that's true. UPDATE (29/09/2015) - I have uploaded test results using the new Kingston Digital MobileLite G4 USB 3.0 Multifunction Card Reader (FCR-MLG4) and CrystalDiskMark 5.0. 2x64, Windows 10 Pro. READ (MB/s): 152.7, 14.67, 152.3, 11.52. WRITE (MB/s): 86.69, 1.231, 85.15, 1.180. 13.18, 92.92, 10.04WRITE (MB/s): 75.92, 1.134, 75.50, 1.093UPDATE (2016-11-16) - My card is still working and I haven't had any problems. I'm looking at new cameras like the Panasonic DMC-FZ2500, Fujifilm X-T2 (two UHS-II card slots!) and Sony A6500 so I can buy more of those Lexar SDXC cards and use the old reliable one as a backup.
