Expand the storage capacity of your Sony PlayStation 4 with help from this Nyko Data Bank 83223 hard drive upgrade dock, which is designed to house most standard 3.5" hard drives. An LED indicator keeps you apprised of your device's status.
Q: How much memory does it hold?
A: You have to purchase a hard drive, recommended is 2tb max.I installed a 4TB and works great
Q: I already upgraded the internal HDD to 2tb; will I be able to add another with this unit?
A: No. Its replaces it with some plastic piece that goes where the hard drive currently resides. If you want to add more, get a 4TB hard drive. I have one and use a 4 TB . no issues and can use all the features
Q: Can you use multiple Nyko hardrives on 1 ps4
A: No you can't add more than one bay, but you don't need to just add a bigger hard drive with this. This is just a bay you also need to buy a hard drive for it. This lest you install a 3.5 desktop H.D.
Q: How easy is it to install and set up?
A: This only works for older models of the PS4. I bought it when I bought a PS4 recently (2014-Feb) and found that this didn't work with my PS4. I returned it and bought a standard notebook HD to upgrade my PS4 to 2GB storage and that worked just fine.
