Are these two sheds actually the same product?

They share the same brand, footprint, height and weight, so they are almost certainly the same shed listed twice. The specs differ on capacity, floor and roof load, so check the listing you buy from.

Which has more storage space?

Product A states 693 cu ft and Product B states 605 cu ft for the same 120 sq ft footprint. The gap likely comes from how each listing measures interior height, so treat both as approximate.

Do I need to build a foundation?

Product A includes a floor frame kit. Product B lists no floor and no foundation, so you would need a slab or a base you build yourself.

Which handles wind and snow better?

Product B lists a 65 mph wind rating. Product A lists a 14 psf roof load against B's 10.24 psf, so A claims more snow capacity but gives no wind figure.

Is one worth paying more for?

Only if the price gap is small. The floor frame kit in A is the main practical difference, and a separate base costs money and time.

How hard is assembly?

Both are metal panel kits that need two people and most of a day. Product B ships with gloves; neither listing includes tools or a foundation.

10' x 12' Heavy-Duty Metal Outdoor Storage Shed with Floor Frame Kit vs 10X12 FT Metal Outdoor Storage Shed with Floor Frame Kit

These are the same 10x12 brown galvanized steel shed from the same brand, sold under two listings with different specs on paper. Product A lists a floor frame kit and 693 cu ft of capacity; Product B lists 605 cu ft, no floor, and a 65 mph wind rating. Buy A if you want the floor frame and the larger stated capacity. Buy B only if its price is clearly lower and you plan to build your own foundation. No current price is available for either listing, so compare store prices before you commit.
