Sony Tough SF-G Series 300MB/s UHS-II V90 64GB SDXC Card Review

Sony Tough SF-G Series 300MB/s 64GB SDXC UHS-II V90 Memory Card

Introduction

The new Tough SF-G series Secure Digital memory cards were announced by Sony on August 28, 2018. Sony Tough SD cards combine 300 MB/s read and 299 MB/s write speeds of the SF-G series with a new ultra-durable construction. Tough cards are the first SD cards to have a monolithic sructure with no external case to break or voids within the card. The result is a card 18 times stronger than the SD specification. Tough SD cards are able to withstand 16 foot (five meter) drops. Further enhancing durability, the cards have no external write lock, connector ribs, or other moving parts to fail. The cards are waterproof with IPX8 rating (deeper than 1 meter) and Sony further specifies that the card with retain data after being submerged at a depth of 5 meters for 72 hours. The card is also dustproof to IP6X which means the card is fully dust-tight. When the card is dirty it can be washed with water and wiped clean without damage.

Sony Tough SD cards are V90 rated for stable recording of high resolution video including 4K and 8K. Tough SF-G cards are available in 32, 64 and 128 GB capacities. This review covers the 64GB SDXC card, model SF-G64T/T1 with UPC 027242908321. The card tested is marked Made in Taiwan on the back. Tough Series SD cards are covered by a five year warranty.

The Tough cards are backwards compatible and will operate in Standard SD and UHS-I modes although their speed will be limited when used in such devices. In UHS-I mode the card supports SDR104 mode which limits the read and write speeds to under 104MB/s.
