Do your test again between EXT2 and NTFS. EXT2 does not journal and is not limited to 2gb. Once formatted EXT2 will show in DD-WRT as EXT4 even though it is actually EXT2.
You will need a psu if you use Esata so use a USB port. USB3 may cause interference so try the USB2 port as well if you have one (or use a USB2 cable from the USB3 port). Check for the interference on the wireless tab and watch what happens to the SNR.
EXT2 works best for me on my R7800, I use the NAS for downloading torrents and subsequent playback of videos.

IDK what articles you are reading, some sources of information are not reliable. I seek information from well establish authorities and/or technical documentation on the subject. everything else is safely taken with a pinch of salt and not to be trusted blindly without verification.
EXT4 for a SSD is better than EXT2/3 IMO given my own personal experience on the subject outside of DD-WRT, mind. The processing power of a SSD is vastly superior to that of a HDD in all aspects and its so fast that journaling becomes a non issue, though it can be disabled on regular Linux, never tried DD-WRT side, however tune2fs is available on DD-WRT to tweak the FS, to disable would be something like tune2fs -O ^has_journal, tune4fs doesn't exist in DD-WRT and that command is originally using tune4fs.
TRIM! DD-WRT -- Busybox includes fstrim.c, however running the fstrim command, without any external SSD mounted yields command not found (could be this is reserved to more powerful routers). It is available as a entware package from OpenWRT. Not a big issue per say, you can simply plug the drive on a Linux system and trim it, if it comes to it.
Unless you have a mechanical HDD I would stick to modern filesystems, they are better featured and can always enable/disable something with tune2fs rather than be limited by non existing features with older FS.
You can also upgrade filesystems with no data loss from EXT2 to 3 or 4, but not recommended on a piddly DD-WRT router CPU, you cannot downgrade FS versions.
