#Blackmagic disk speed test for windows 7 professional#
The final test was the shock test in the specifications, LEXAR Professional states that the card is Shock resistant (50, 11 / half sine wave. Either way, the card worked well in both conditions. Just a not, I let the card return to ambient temperature between the two tests rather than shocking it from one to the other.
However, with a storage range of between -25✬ and 85✬, it seemed OK to pop it into a freezer bag, seal it and then pop it in the freezer for 24 hours and then leave it shaded in a spot in the garden that was reaching just over 40✬ in direct sunlight. Unlike most UHS-II cards that now offer some moisture protection, there’s no mention of this in the specifications. The card’s speed will ensure that the storage media keeps up with the action with transfer speeds that are benchmarked at roughly three times that of a standard UHS-II SD Card.Īnother important feature of any memory card besides the camera is its robustness. This means they make an ideal choice for cameras such as the A7S III, capable of capturing 4K at 120fps. The card is designed to fit cameras such as the Sony A7 IV and A7S III that are compatible with the smallest of the new CFExpress card formats.Īs memory cards go, the CFExpress cards’ size is about half that of the more popular CFExpress Type B cards and a touch smaller than a standard SD Card.Īs with the range of all CFExpress cards, this new release has been designed to keep up with the action offering transfer speeds that exceed those possible by the current cameras. The Lexar 160GB Professional CFexpress Type A Card Gold Series is one of the only alternative Type A CFExpress cards on the market against Sony’s Tough range.
