PS4 External HDD RAID setup for PS4

[amirzaim]

Recently I came up with the idea of bringing RAID storage as the external drive for PS4 console and then I bought a special external HDD enclosure that allow user to set up the RAID disks from hardware level and I tried it out by putting both 500GB disks which came from PS3 and PS4 console respectively.

In order to set up these disks as RAID 0 setup, I have to look at the instruction manual on how to setup RAID 0 disk and then it worked initially when my PC detects RAID 0 disks as single 1TB storage. Then, I'm tried it out by connecting these drive with my PS4 slim console, it detects the drive and also formatted as the external drive for PS4. Why you have to trade-in your existing drive to bigger drive when you can just combine both disks as one big capacity drive?...

However, this method have its drawbacks as the hard drive failure risks is same as ordinary RAID 0 disks and you can't just simply put 2TB and higher capacity disks for RAID setup. This is because most of 2TB and higher capacity disks have something called Shingled Magnetic Recording (SMR) technology which allows more capacity but sacrificing write speed performance. Putting these disks for RAID setup will eventually fail and the worse thing is the write speed is just terribly slow.

I have an internal raid adapter for my PS4 pro. It houses 2 m.2 drives in raid 0. Downsides have been: I can't suspend the PS4, and if a brown out happens the system shuts down (it's connected to a battery backup). I'm thinking of getting a couple drives for an external raid instead. Either raid 10 or raid 5. Redownloading 5tb of games would suck.

I don't think your config would work in RAID because both drives are of different sizes.

RAID 0 requires drives of the same size.

you should've kept a copy of your pkgs, because you can't remarry or even create a patch without the base pkg. there's an app to take them from the system, since they're essentially app.pkg on there, but I don't recall the name nor have I used it. they're going to have to remarried now though, since the base and patch must be from the same dump or else it will error when installing the patch.

My current raid 0 is 2 2tb drives. Looking at raid 10 for the redundancy while still being quick.
This is the current adapter I have been using for the last year or so: https://www.newegg.ca/startech-com-25s22m2ngffr/p/370-0006-00001?item=9SIA7BB3YZ5209

But mine's seems still working well despite having different drives but same capacity. Somehow, external drive is still useful when my PS4 went malfunctioned after several months never switched on and had to sent to Sony Centre to fix it, resulting $250++ repair costs that consist of changing PSU unit and even the motherboard. Then, I managed to restore it by using the external drive which I kept during service periods.
