== Incompatible drives ==
* smaller than 160GB (20GB is smallest for ps3, 160GB smallest for ps4)
* multidrive bridging / port replicator ([http://www.psdevwiki.com/ps3/Dual_Firmware#Solutions_for_swapping_.2F_externalise_the_harddrive same limitation exist on ps3])

==== Western Digital 1TB HD + 120GB SSD ====
In early 2013 the Western Digital Black-II WD1001x06xdtl looked promising, as a SSHD with 1TB of platter storage and 120GB of NAND SSD storage, but as the review in november 2013 shows, it is ''not'' a hybrid drive, does not transparently combine both platter and SSD to a single addressable storage over SATA (the primairy storage is the SSD, it needs reinitialisation for accessing the 1TB platter storage, as such it is not recommended for non Windows systems including MAC and ps4/ps3) and in fact the overal performance is not even rememberable: http://www.storagereview.com/wd_black2_ssd_hdd_review / http://www.anandtech.com/show/7682/the-wd-black2-review

: This drive will not work since the PS4 will not boot properly and it displays a error message that the [[System Firmware|Operating System]] needs a [[Harddrive]] with 160 GB of free space at least - and it seems that this [[Harddrive]] would be totally insufficient even when the SSD part, which it seems that the PS4 has access for it, would have 160 GB or even more of free space. The PS4 is not able to access the 1 TB of space from the HDD part, so you would not have any space advantage. Even if it would have access to both parts, how it can manage both parts when it needs to create [[Files on the PS4#Partitions|15 Partitions]] for running properly (15 Partitions distributed on the SSD and HDD together)? It's a similar situation when you want to run this [[Harddrive]] on a normal Computer '''before you installed a operating System'''. Windows Operating Systems NT 6.0 and higher (thus not BSD, MacOSX, Linux, DOS, CP/M, AmigaOS, OS/2 etc.) detects the HDD part first and you can use the SSD part only after installing ''closed source Windows drivers''.).

==== Western Digital 4TB HD + 128GB SSD ====
[http://anandtech.com/show/8820/western-digital-shows-off-a-128gb-ssd-4tb-hdd-35-sata-express-dualdrive Western Digital showed another model], but since it uses SATAe (PCIe 2.0 x2 over SATA Express connector) it is not compatible. Also, the drive consists of a 128GB SSD along with a 4TB hard drive and thus is not a true hybrid SSHD.
