SanDisk Ultra and Extreme series show a clear differentiation in their write speeds. The SanDisk Ultra reaches a maximum write speed of 80MB/s, which is suitable for standard photography and 1080p video recording. In contrast, the SanDisk Extreme offers a higher write speed of up to 90MB/s. The Lexar may be inferior to the SanDisk Extreme, but it's still infinitely better than an Ultra. The cost difference is usually even less, if existent at all, with lower capacity cards. The Samsung Evo Select 512GB is actually on sale on Amazon for $45, while the SanDisk Ultra is actually $53. The Ultra is just a rip off. Im currently using Sandisk Extreme 128GB U3 and so far Ive had no issues. But Ive been advised to either Nextbase Cards or Sandisk High Endurance Card. Looking for any first hand advise re your experience with Sandisk cards. p.s just checked halfords website and they are selling Sandisk Extreme marked as suitable for dashcam. Thanks S. The Sandisk Ultra Plus has an above average consumer performance profile and is available at a fantastic price. It's one of the cheapest SSD's we have reviewed and we like it a lot. With a real world speed of 488.1 MB/s and an AS-SSD Total score of 910 points, the Ultra Plus is able to handle consumer workloads reasonably well and enterprise .
