Sony has announced a new SD cards, the SF-G series, which the electronics giant claimed “will be the world’s fastest SD cards” when it becomes available this spring. And what is the speed we are talking about? A write speed of up to 299 MB/s. That’s blazing fast as compared to the measly 80 or so we are getting on a Class 10 UHS-I variety and easily topping SanDisk Extreme PRO SDHC UHS-II and Lexar Professional 2000x UHS-II – both which touts read and write speeds of 300 MB/s and 260 MB/s, respectively. Without going too much in depth though, it is without doubt that this super speeds card is reserved for the pros, you know, for those who requires quick successive shooting and of course, 4K video recordings, for examples.
According to Engadget, Sony’s SF-G series card is not your run-of-the-mill SD card; in order to facilitate speedier transfer of large amount of data, this new card has UHS-II interface that presents a second row of connection pins on the card to bump up the transfer rates and it will need the speed it can get because the biggest storage available is pegged at 128GB, which means if you are doing 4K videos, transfer will occur quite frequently. However, it is a new thing and therefore, as far as the desired rate of transfer is concerned, it will only realize its full potential when used on compatible hardware. As such, Sony has a specialized card reader to ensure a speedy transfer to most machines even if they are not UHS-II compatible.
Other side bonuses of this new speedy removable storage include compatiblity with Sony’s file rescue software and a robust, rugged designed that would enable it to survive assaults dished out by water, extreme temperatures, shock and even harmful beam of X-ray. Though it is coming out this spring, it has no sticker on it yet, but a check with Amazon indicates that a 32GB Sandisk Extreme Pro SDHC UHS-II is priced around 60 bucks and so, we expect a new tech like such to command more. Maybe, a lot more, depending on Sony’s strategy.
