用来将原来PS2记录卡上的数据转移到PS3的相关存储介质上。可以在PS3上继续自己的游戏。

November 28, 2006 - With the PlayStation 3 having only been in stores for 11 days now, various add-ons and peripherals are still making their way into stores. One of the hard to find items is the Memory Card Adaptor, a boxy device that allows you to transfer your PS2 or PSone saves from a Memory Card onto your PlayStation 3's hard drive so that you don't have to start from scratch while making use of the system's backwards compatibility.
For those of you who don't know how it works, here's a quick recap on how PS2 and PSone saves are handled on the PlayStation 3. Under the Game section on the Cross Media Bar, you'll find the Memory Card Utility. Your first option here is New Internal Memory Card which creates a save space for backwards compatible games. After choosing the card type and giving it a name, the PlayStation 3 then sets aside the appropriate amount of space for the given card type on the hard drive. When you play a game, you choose which virtual card is in Memory Card Slot 1 and Slot 2, which you can swap on the fly. You're able to create an unlimited number of cards, though you can't surpass the usage of 8MB or 15 blocks on any one card.
The Memory Card Adaptor for the PlayStation 3 is a rather simple looking box that measures approximately 2.25" x 2" x 0.75". A single Memory Card slot is located on one side and a USB connector is on the other - you use the same USB cable to connect the adaptor that you use to charge the controllers. The device does not ship with its own USB cable.
When you connect the unit to the PS3, the inserted Memory Card will show up inside of the Memory Card Utility. Pressing X will bring up a message that says, "The saved data on the selected memory card will be copied to the hard disk. Do you want to continue?" Choosing yes brings up a naming prompt and allows you to give your new Internal Memory Card a name, and then it copies over to the hard drive full and intact.
Note that there are no advanced options to bring up by pressing Triangle while the card is highlighted - all you can do is copy its contents. You also can't explore the card and copy over specific game saves. It's all or nothing, though you're of course free to delete saves at will once the card has been copied over to the hard drive.
While all of this is rather straightforward and painless, the first bit of bad news is that you are not able to copy saves back to a physical Memory Card. You can copy them between Internal Memory Cards of course, but not back to a physical card. Once they're on the PS3's hard drive, it looks like they're there for good unless you go through a series of other copying processes by using a SharkBoard or some such, though we haven't tried jumping through these hoops ourselves yet.
An issue for some folks is that the adaptor will not work with cards that have more than 8MB of storage space. We have a Mad Catz 16MB card that we tried to copy, and while the card is recognized, a non-descript error is returned as soon as we try to copy its contents.
The Memory Card Adaptor also cannot be used as a save device directly, so you aren't able to assign it to a card slot and use it directly with PS2 or PSone games. Lastly, Windows XP recognizes the adaptor as some sort of USB device, but doesn't know what drivers to install, rendering it useless with a PC.
At $14.99, the Memory Card Adaptor does fill a very large void, though it certainly isn't without drawbacks. It would be very nice if you could copy saves back to a card, though it's possible that this will be remedied in a future firmware update.
