DOS ain't dead

BD-R with UDF filesystem (Miscellaneous)

I still have some DVD-RAM discs but use them barely now. I just take one and loaded in drive. It took quite long time to read just a directory structure. Reading every file takes another tens of seconds, sometimes got crc error. I cannot write to disc, error not enough space or media changed despite there are still some 250MB left. So I would say nothing superior over common crappy CD/DVD disc that I trashed a lot of them before...

I checked DVDForm tool (part of windows DVD-RAM driver package) an it offers formatting in UDF 1.5, 2.0, 2.5 and FAT32. I didn't try FAT32 as everywhere I read the UDF is reccomended for DVD-RAM. Maybe it's because FAT FS needs often to write to 3 different disc locations (FAT table, directory entry, data itself) that can prolong seek access time esp. on optical drives so I guess UDF is optimized for this.
I lost my interest on BluRay as it's incease of capacity is not enough to nowdays demand, drives and media are quite expansive and nobody in my neighbour have it.

BTW R. Loew already had a solution for bigger sectors/disk - TeraByte Plus Package 3.0
The TeraByte Plus Package is a set of Tools and Patches that provide support
for Hard Drives with Larger Capacities and/or Larger Sector Sizes than was
possible previously with DOS and Windows 98 and 98SE.
Support is provided for Hard Drives up to 32768TiB (16TiB for USB Drives).
Extended Support is provided for 64-Bit Addressed SCSI and USB Drives.
Not tested due to no available Drives.
Logical Sector Sizes are supported up to 32KB in DOS and 4KB in Windows.
Larger Logical Sector Sizes can be emulated on Drives with smaller Sectors.
Support is added for Clusters up to 256 Sectors in length, allowing for
extra large FAT12 and FAT16 Partitions if needed.
Support provided for Multiple Extended Partitions per Drive.

The package includes patched MSDOS 7 IO.SYS, ESDI_506.PDR and some VXDs, partitioning, formatting and bootmgr tools...

DOS gives me freedom to unlimited HW access.
