BootAble – FreeDOS boot testing freeware
To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.
GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.
The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.
You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.

But your 850 is about half and 860 about a quarter of my speeds with these drives. Even when ignoring the problem areas, they seem limited by a slow interface or something? 137MB/sec. for an EVO is quite atrocious.
Thank you; I noticed that, too. This is an old mainboard, DFI LP JR GF9400-T2RS (circa 2008?), which has SATA 2.0 (Serial ATA-300) interfaces. I believe the above result was due to an inferior BIOS setting (IDE?). After switching BIOS to use the AHCI controller I had these results:
The odd thing is why drive 81 and 82 reached full speed and not drive 83 on the 2020-12-31 at 10:58 run.
