Know before you buy
pSLC (pseudo-Single Level Cell) technology is designed for higher endurance and reliability compared to standard flash memory. It allows the card to handle more intensive write cycles, making it ideal for professionals who record high-bitrate video or shoot in burst mode frequently.
The Delkin BLACK card is designed for broad compatibility with cameras that support the CFexpress Type B standard. However, it is always recommended to check your camera manufacturer's list of approved media to ensure optimal performance with your specific model.
While 150GB provides a solid balance of speed and storage, 8K video files are extremely large and consume space quickly. If you are shooting long-form 8K content, you may need to offload your footage frequently or consider a higher capacity card.
Delkin offers a specialized replacement service for the BLACK line, meaning if your card fails, they prioritize sending you a replacement within 48 hours. This is intended to minimize downtime for working professionals who cannot afford to wait for standard warranty processing.
Yes, the card is built with a rugged, shockproof, and water-resistant design. While it is engineered to withstand harsh environments, it is still a piece of precision electronics and should be handled with reasonable care.
