If you already are using a 256GB SSD and then have also filled a 128GB, you should consider taking some data off into a different sdhc / usb drive, something that you don’t always need. That will take away the need for a single drive thats as large and also give you better pricing.

The Lexar was the only one available for a long while. B&H had the PNY listed as arriving soon, so I signed up for the notification and ordered it as soon as they had it in stock on May 7th.

Performance is underwhelming. It’s acceptable for my purposes (backup drive) but I wouldn’t use it for video, even if on paper it is UHS-I certified.

I have the Lexar 256GB and thought it was the only of its kind…have you a link to any other as I cannot find one? Would be a great review comparison.

As I mentioned in my second comment, I made a mistake: the 256GB SDXC are PNY, not Transcend (or Lexar). The PNY are much cheaper, but I suppose you have to pay the price in reduced performance.

Hey Fazal are you sure that you have 256 GB SDXC cards from Transcend?
Only Lexar has 256 GB SDXC cards.
Transcend has 128 GB SDXC max.
Transcend has 256 GB Compact Flash Card 800X!
