OK, obviously NOT playing cards, but I sometimes run into related (and not so related) items that I will offer here before I list them on eBay.
I have found a real deal on NAS sized internal hard drives made by the Hitachi division of WD (AKA Western Digital) branded "HGST He10 3.5" helium based UltraStar". Yes, that's a single drive with 10 Trillion bytes storage, actually closer to 9.1TB, but ten trillion bytes accurate.
These drives list for $459 and sell for up to $600 until recently, and now are down around the $350 price point factory refurbished or more.
I have one for $300 + actual shipping = $307 for 2- to 3-day Priority Mail delivery. It's $319 by PayPal if you can't send it as a gift.
If there is more than one person interested, I can get more at that price. Right now Seagate Barracuda Pro 8TB (6TB for that matter) and WD Red Pro drives af the same size are selling for more. Here's the listing for eBay that I have not posted yet.
Let me know if you are interested.
If you have gotten this far, these are the SATA3 512e Advanced Format (LE604) version.
