There is also OVH (not affiliated, just happily using their VPS), but I would consider switching to 2 providers, as any provider can have data loss or just lock your account at anytime for any reasons. 2 providers with free egress so you can easily replicate data between them.
You can however set the block size to something quite large, which means you write the same random pattern spread out over multiple blocks repeatedly. If you pick an "odd" block size (like say, your native block size multiplied by 47), it's highly unlikely your disk under test will be swapping around "groups of 47 blocks." (I usually just do a nice multiple, like 4K16, but if you're super paranoid a weird multiple should be pretty much good enough). You won't get reporting of which exact* blocks on the drive are failing, but these days, that isn't really useful information - if any blocks are failing, warranty or ditch the drive.
Just being able to inject traffic is already huge as it allow you to send IPv6 router advertisement, which sometimes allows you to change the DNS config
I use Tomato too, but I wouldn't say it offers many benefits over OpenWrt. The main thing is that routers based on Broadcom chipsets often only work with very old Linux kernels (such as 2.6.xx kernels), as the drivers are closed source. For these routers, the primary third-party router OS choice is to use Tomato.
In OpenWrt there is ujail, you give it an ELF (or multiple) to run, it'll parse them to find all the libraries they need, then it creates a tmpfs and mount bind read only the required files.
