The PRO-CINEMA CFexpress Type B Memory Card is designed for professionals seeking cinema-quality footage with sustained write speed performance to deliver cinematic footage. The new card has a durable enclosure to protect the disk and the all-important video footage. ![SanDisk PRO-CINEMA CFexpress Type B Memory Card front ]() We reviewed the previous Type B memory card, the [SanDisk Professional PRO-CINEMA CFexpress VPG400 Type B](https://www.storagereview.com/review/sandisk-professional-pro-cinema-cfexpress-vpg400-type-b-review), released by SanDisk just over a year ago, and concluded that the card did pretty well. We didn’t see any problems with the card itself, but we noticed it failed to match the performance of Lexar’s professional DIAMOND CFexpress. We are interested in seeing if this has changed this year since both companies have released updated memory cards for their respective lines. ## SanDisk PRO-CINEMA CFexpress Type B Specifications The PRO-CINEMA line features SanDisk’s highest-quality CFexpress cards on the market. The card is built for high-level professionals looking for the best 8K video-capturing technology. ![SanDisk PRO-CINEMA CFexpress Type B Memory Card Package]() The card has a claimed minimum write speed of 1500MB/s and a maximum write of 1600MB/s. The read speed is listed as 1700MB/s. ![]() The SanDisk PRO-CINEMA CFexpress is available in 320 GB and 640 GB. The 320GB version is currently going for $399.99  and the 640GB is going for $660 on [Amazon](https://amzn.to/3GpCvLe) (affiliate link). The card reader can be purchased for an additional $74. The memory card comes with a lifetime limited warranty. See the full list of specifications below: | Category | Details | | --- | --- | | Capacity | 320GB, 640GB | | Form Factor | CFexpress Type B | | Connector | CFexpress Type B | | Compatibility | Cameras with CFexpress Type B slots | | Sequential Read Performance | Up to 1700MB/s | | Sequential Write Performance | Up to 1500MB/s | | Interface | CFexpress | | In The Box | SanDisk PRO-CINEMA CFexpress™ USB Type B Card | | Warranty | Lifetime Limited Warranty | | Dimensions (L x W x H) | 0.09″ x 1.43″ x 1.68″ | | Weight | 8.5gms | ## SanDisk PRO-CINEMA CFexpress Type B Performance We plugged a Lexar USB 2×2 reader into our [Lenovo ThinkStation P520 Workstation ](https://www.storagereview.com/review/lenovo-thinkstation-p520-review)as the test platform for our tests. We were sent the 320GB memory card for our review. SanDisk quotes a sustained performance of 1400MB/s write and a maximum of 1500MB/s. For our iometer testing, we will compare the SanDisk PRO-CINEMA to two relevant CFexpress type B memory cards on the market. The [Lexar Professional DIAMOND CFexpress](https://www.storagereview.com/review/lexar-professional-diamond-cfexpress-type-b-card-review) is a rival to SanDisk in the CFexpress memory card industry. The [SanDisk Professional PRO-CINEMA](https://www.storagereview.com/review/sandisk-professional-pro-cinema-cfexpress-vpg400-type-b-review) is the previous generation of the current PRO-CINEMA CFexpress memory card. As always, we are starting our testing with the Blackmagic DiskSpeed Test. Our tests revealed the memory card had a write speed of 1378.9MB/s in Blackmagic, although higher in our subsequent testing with higher load levels. The read result measured 1458.8MB/s during our testing. ![]() Next is the IOMeter testing, where we put the SanDisk PRO-CINEMA CFexpress through single-thread and four-thread workloads. The SanDisk PRO-CINEMA CFexpress performed significantly better than its previous counterpart. Read results are better, but the immense difference can be seen in writes. Performance against the Lexar Professional DIAMOND CFexpress is much more competitive than the previous models. The numbers are pretty close, with the Lexar pulling ahead in 2MB sequential reads but falling behind in IOPS counts. | **IOMeter (1-Thread)** | | | | | --- | --- | --- | --- | | **Test** | **SanDisk PRO-CINEMA CFexpress 320GB (current)** | **Lexar Professional DIAMOND CFexpress 256GB** | **SanDisk Professional PRO-CINEMA CFexpress 256GB (previous)** | | 2MB sequential write | **1158.2MB/s** | 1,256MB/s | 871.4MB/s | | 2MB sequential read | **1262.7MB/s** | 1385.4MB/s | 1,091.8MB/s | | 2MB random write | **1106.3MB/s** | 1,130MB/s | 341.0MB/s | | 2MB random read | **1223.7MB/s** | 1,204.1MB/s | 972.3MB/s | | 4K random write | **17234 IOPS** | 14,897 IOPS | 2,985 IOPS | | 4K random read | **4908 IOPS** | 4,328 IOPS | 10,785 IOPS | The 4-thread performance for the SanDisk PRO-CINEMA CFexpress was better than expected. Writes are above the claimed value of 1500MB/s and reads hover near stated levels. The numbers between SanDisk and Lexar are close, but SanDisk wins in four of the six categories. | **IOMeter (4-Thread)** | | | | | --- | --- | --- | --- | | **Test** | **SanDisk PRO-CINEMA CFexpress 320GB (current)** | **Lexar Professional DIAMOND CFexpress 256GB** | **SanDisk Professional PRO-CINEMA CFexpress 256GB (previous)** | | 2MB sequential write | **1541.3MB/s** | 1599.9MB/s | 1,276.5MB/s | | 2MB sequential read | **1702.7MB/s** | 1767.5MB/s | 1,320.9MB/s | | 2MB random write | **1544.8MB/s** | 759.4MB/s | 392.4MB/s | | 2MB random read | **1644.6MB/s** | 1552.4MB/s | 1,306MB/s | | 4K random write | **68,608 IOPS** | 54,167 IOPS | 8,705 IOPS | | 4K random read | **24,370 IOPS** | 14,913 IOPS | 40,332 IOPS | ## Our Final Thoughts ![SanDisk PRO-CINEMA CFexpress Type B memory card, frontside]() The SanDisk PRO-CINEMA CFexpress performed well, considering it had somewhat equal performance to the Lexar Professional DIAMOND CFexpress 256GB, a good overall improvement. The SanDisk PRO-CINEMA also boasts significant improvements in write performance compared to its predecessor, more good news for SanDisk, who’s working to repair their brand image with creative pros. Ultimately cards in this class need to perform well enough to enable the super high-res imagery to write to the flash media. The SanDisk PRO-CINEMA CFexpress gets the job done on this front, while also delivering a little more capacity than both the prior model and the Lexar competitor. **Engage with StorageReview** [Newsletter](https://www.storagereview.com/storage_newsletter) |  [YouTube](https://www.youtube.com/user/StorageReview "Opens in a new window") | Podcast  [iTunes](https://podcasts.apple.com/gb/podcast/storagereview-com-storage-reviews/id1060681115 "Opens in a new window")/ [Spotify](https://open.spotify.com/show/1y6VnznABhHeOSMOmbDTz0 "Opens in a new window") |  [Instagram](https://www.instagram.com/storagereview/ "Opens in a new window") |  [Twitter](https://twitter.com/storagereview "Opens in a new window") |  [TikTok](https://www.tiktok.com/@storagereview?
