The key detail is drive generation: Alpha One Gen 1 and Alpha One Gen II use different sealing layouts, so checking the drive serial number before ordering prevents an expensive mismatch.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping:\u003c\/strong\u003e Ships same or next day for fast Canada wide shipping. ⚓\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":43563851776036,"sku":"32511A1","price":116.24,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/9f0cdc9b-7619-476f-be9d-6b2da9a9d276.png?v=1779393490","url":"https:\/\/marisolmarine.com\/products\/merc-133","provider":"Marisol Marine Company","version":"1.0","type":"link"}
