SanDisk Extreme PRO 512GB World’s Highest Capacity SD Card

Since SanDisk unveiled its first 512MB SD card in 2003, capacity demands have increased exponentially and the new 512GB SanDisk Extreme PRO SDXC UHS-I card represents a 1,000-fold capacity increase in just over a decade, yet maintains the same size footprint. SanDisk’s most powerful and highest capacity SD UHS-I memory card yet, the 512GB card delivers write speeds up to 90 MB/s* and UHS Speed Class 3 (U3) recording speed for high resolution, real-world color and stutter-free 4K Ultra HD video1. Transfer speeds up to 95 MB/s* move data quickly for efficient post-production workflow.

International Broadcasting Convention, AMSTERDAM, Sept. 11, 2014 – SanDisk Corporation (NASDAQ: SNDK), a global leader in flash storage solutions,  launched its 512GB** SanDisk Extreme PRO SDXC UHS-I memory card, the world’s highest capacity SD™ card on the market. The new offering is designed to meet the demands of industry professionals who require the most advanced gear available for shooting 4K Ultra High Definition (3840x2160p) video, Full HD video (1920x1080)1 and high-speed burst mode photography.

The 512GB SanDisk Extreme PRO SDXC UHS-I card delivers both the speed and capacity needed to support 4K Ultra HD video capture, enabling users to shoot tremendous amounts of content without disrupting the moment.

The new offering comes with key features designed for pro-level action:

  •     Built for and tested in harsh conditions—temperature proof, water proof, shock proof, and x-ray proof2
  •     Lifetime limited warranty3
  •     RescuePRO® Deluxe data recovery software download offer4, for bringing accidentally deleted images back to life
 The Extreme PRO comes in SDXC format and utilizes UHS-I interface, which is good for up to 104MB/s.

The 512GB Extreme PRO consists of 32 x 128Gbit (16GB) dies. The photo above is from SanDisk's 2014 Investor Day presentation where the company claimed that it has the technology for a 32-die SDXC card and with the Extreme PRO the technology has made it into the retail. Since SanDisk/Toshiba doesn't have a 256Gbit NAND die (nobody has one in mass production yet), the only way to achieve 512GB is through a 32-die stack. SanDisk hasn't specified whether the NAND is MLC or TLC, but given that it is a high-end product I'm guessing it is MLC based.

Stacking more dies on top of each other will always have a negative impact on yield as the wires have to be longer and there are more wires to connect, so the room for errors increases and thus the manufacturing cost goes up as well.

 All capacities are available now and the MSRP for the 512GB model is $800, which is certainly high since 512GB SSDs retail for close to $200.
