The LG Optimus 7 has performed impressively well in head-to-head speed comparisons with other Windows Phone 7 devices, and now we may know why: a teardown has revealed that it’s one of the rare launch devices to use flash NAND for storage instead of microSD cards. In fact, Samsung’s Omnia 7 is the only other shipping WP7 handset we’re aware of that has eschewed the slower-but-cheaper-and-more-abundant cards. While some folks may bemoan the inability to upgrade these two handsets’ storage, the truth of the matter is that only the Samsung Focus grants card slot access without risk of voiding the warranty, not to mention the fact that day-to-day performance improvements would seem to outweigh the capability to double existing capacity.
Much ado has been made about the Windows Phone 7 storage situation, with Microsoft initially trashing microSD as a whole, only to later begin working furiously to test and certify as many cards as possible. However, as of this writing, there are still no cards on the market that have been approved by Redmond as having the necessary characteristics to support the WP7 file system.
