Western Digital is about to start selling its own storage expansion cards for Microsoft's Xbox Series X|S game consoles. BestBuy listed these cards on its website over the weekend, ahead of a formal launch, revealing that these devices will be cheaper than those exclusively offered by Seagate for well over two years (via The Verge). 

The WD_Black C50 Expansion Card for Xbox listed by BestBuy (archive link) has a 1TB storage capacity and is priced at $180. By contrast, Seagate's 1TB storage expansion card has a list price of $220, but is now available for $190 at Amazon. Meanwhile, Seagate's 512GB drive has an MSRP of $110, whereas a 2TB drive costs $360 (down from $400 originally).  

Interestingly, Amazon has placeholders for 4TB, 5TB, and 8TB expansion cards too, which suggests that Seagate might be prepping higher-capacity versions of expansion SSDs for Xbox Series X|S consoles.

Microsoft's latest Xbox Series X|S game consoles use proprietary storage expansion cards. These cards come in the CFexpress 1.0 Type-B form factor, but they use two PCIe Gen4 lanes, which goes beyond the two PCIe Gen3 lanes that the CFexpress 1.0 Type-B specification requires.  

Microsoft charges a royalty for storage expansion cards designed for Xbox, and so until recently, Seagate was the only company willing to make them. Since these cards have been available exclusively from Seagate since the launch of the latest Xbox machines in late 2020, they have been pretty expensive.

It's noteworthy that an enthusiast has demonstrated that it is possible to build an expansion drive for the latest Xbox consoles by using a CFexpress-to-M.2-2230 adapter (which was initially intended for constructing storage devices with greater capacity for cameras), provided you bring your own SSD. These adapters are currently available for $30 from Amazon.

    Still literally double the price of PS5 SSD for $90:
    Or you can buy the PS5 2TB drive for $160:
    In case you're wondering, Nextorage was an SSD company started by Sony, then bought out by Phison who makes the memory controller chips for most of these SSD's anyways.

    Still not buying that overpriced crap.
    Stop trying to charge double for your "proprietary" format which is no better than what you could get from industry standard implementations.

    Sure a small premium for the form factor and ease of use but almost DOUBLE? Stick it.

    This is one of the few things that I have always disliked about Xbox consoles. As long as there has been expandable proper drive storage there has been proprietary storage.
    A Xbox is basically just a stripped down appliance PC and very similar hardware wise to a PS5. Sony couldn’t care less about your storage device, even if it doesn’t meet their hardware requirements you can still use it.
    Meanwhile MS is selling half speed not quite industry spec drives for outrageous mark ups. Even back when they were SATA hard drives.
    Sure you’ve always been able to “make one work” but the fact that it’s so easy to do that is biggest reason for why you shouldn’t have to. Just drop an industry standard drive in and go about your life.
