Put PS4 HDD in PS3, upgrade PS4 HDD?

I was about to upgrade my hard drive for my old fat 60GB PS3 to a 500GB drive. I was thinking I should just put my PS4 drive in the Ps3, and buy a hybrid drive or something for the Ps4?

I really don't know if I will need more storage for the ps4, but definitely need it on the Ps3. I am very impressed with all the PSn offerings (I barely gave it a look until I got the ps4). The drive I was going to buy for the PS3 was a seagate momentus for $58. It looks like I can get a hybrid 1TB Seagate for about $100. For a difference of $40, I think it's a good idea to just upgrade both. Just bouncing the idea off you folks.

I read instructions for transferring data from the Ps3 to an external, and I'm hoping it's similar for the Ps4. I'll just use a 500GB external I have. Once on the Ps4 (backup/restore to new drive), and then again on the PS3
Ps3 (backup/restore to old PS4 drive).

Thanks!

Just a tip when you're putting in a new drive into the PS4. Make sure you download the full restore firmware its above 800mb. The one that's 300mb is just a update and doesn't contain the full image.

IMHO I don't think the Hybrid drives are worth the extra cost. From the benchmarks someone ran on youtube and in comparison to my load times for the same game with my 7200RPM drive the difference I think was a second or two in the load times on the PS4. I'd personally rather put that $40 to another game.

I think hybrid drives are the way to go. Just make sure you get ones that do not require drivers to unlock the SSD. Seagate Laptop Thin 500GB or 1TB would be the way to go.

They need to hurry up and release 16GB NAND version of these as it was found 8GB isn't enough for PS4.

I put a hybrid 1TB in my PS3 and got a nice speed boost in booting and game loads. Not huge, but it is noticeable. Don't really need it in the PS4 yet because I play the PS3 so much more.

Thanks guys. I bought this popular seagate 1TB hybrid for the PS4:

Kicked the Ps4 drive down to my old fat PS3. Of course my external I haven't used for anything in awhile took a dump. I had to get creative for backing up the PS3, and use spare disk I had with a USB converter after making a fat32 partition on it. But all is well that ends well.

That's what I would do. 1TB might be as low as you should go anyway for a PS4. My 250GB SSD is holding me up so far on my PS3, but 500GB would have been safer. A hard drive died in one of the desktops laying around so I used my old 500GB 5400RPM from PS3 for it and put Windows to it. It's good to have HD's laying around lol!
