You didn't understood me or I wasn't precise enough. Technically You can always clone sector by sector devices, whatever they are (SSD included). But in PS3 case, You will not be able to extend "game partition" using free sectors because PS3 don't doing it and no one wrote homebrew for that on PS3 or PC side (also it is one of the partitions in the middle of drive so since PS3 fw doesn't support LVM, it demand to move "dev_hdd1" ( game/fw upd cache) and if exist "dev_hdd2" (OtherOS partition)). So if user will make SBS copy and write it on larger media, it will be in the same size as in old which is pointless in other purposes than data recovery scenario (which is pointless more if user have dumped ERK).
Cloning in meaning of copy data from occupied sectors written in fs tables is currently impossible because:
- we don't understand whole logic (mostly VFLASH area which is device image written raw on partition and encrypted second layer; and empty islands (none encrypted areas filled by zeroes in most cases))
- we don't know how to rebuild it from scratch
- almost whole HDD is encrypted per console keys which must be dumped and algos depend of model family (excluding GEX units on which ATA and VFLASH keys are always the same and in the same way used for encryption)

X360 case is totally different. Their HDDs aren't encrypted and their easy to understand mappings, including FATX, is rather easy to crate from scratch. The problem with those HDDs are that console read they signing which based on i.e HDD fw version. We haven't private key used to forge that sign (put somewhere in MBR, don't remember now, so I could be wrong) so we cannot changed HDDs. Why then only WD? Because for few models their service software allowing to change some data in SA, allowing user to fake this information, matching to old HDD so X360 thinks it is the same drive. If we have that key, then we would be able to prepare any drive, including cloning (of course it still needs dedicated app for that, not any cloning software for PC stuff).

Well, in summary. Every platform have it's own "issues". Some are very hard to beat because they are part of security ecosystem (like i.e PS3 or X360), some easier like i.e NVidia Shield (which using GPT from last sectors, not first, so many peoples thinking that hard drive change is impossible ;p). Cloning is always possible if we goes strictly to this word meaning but limited usage by closed environment.
