Lexar Professional 128GB Cards
I greatly favor high-capacity cards because they act as an accumulative backup for my field work (redundancy to laptop download+backup).
There was a lot of interest in the Lexar 128GB Compact Flash deal I posted about a month ago. POI: a recent photo tour client indicates that the Lexar 128GB card was noticeably faster in his Leica S when shooting than the previous card, and worked without issues (current model Leica S).
While not quite as deep a discount, the Lexar 128GB CompactFlash and Lexar 128GB SDXC cards remain highly appealing on a speed+capacity+price basis.
Lexar 128GB CompactFlash and Lexar 128GB SDXC
What caught my eye was a 2-pack Lexar 128GB SDXC 1000X cards for only $126 with free expedited shipping.
Even more appealing for those needing the capacity, see the 2-pack Lexar 256GB SDXC 1000X cards for only $275 with free expedited shipping. In the past, the 256GB cards have carried a steep price per GB premium, but the price per gigabyte now is only marginally higher than the 128GB cards.
Card readers: what has worked well for me for some years is the Lexar Professional USB 3.0 Dual-Slot Reader, but see also Lexar CFR1 card reader for Compact Flash or a fast USB3 card reader.
