Which firmware version do i use

[uronemus]

Ok just ordered sata card with VIA 6421A chipset and sata cable to connect to my 360's samsung drive

Got extreme firmware but which do i use A, b, C, D? or does it depend on my drive type?

With Xtreme 5.2A, backups are always read at 12x speed, the same
speed as originals. The read speeds of original discs are unaffected.
With the faster reading speed, the drive is significantly louder, and
may have problems reading cheaper media, but you have the benefit
of slightly faster loading times.

With Xtreme 5.2B, backups are always read at 4x speed. The read
speeds of original discs are unaffected. With the slower reading
speed, the drive is quieter, may read cheaper media better, but has
slightly longer loading times.

With Xtreme 5.2C, the default backup read speed is 12x. When an
original disc is placed in the drive, all subsequent backups will be
read at 4x. Read speed of original game discs will remain unaffected.
Restart the system if you wish to read backups at 12x.

With Xtreme 5.2D, the default backup read speed is 4x. When an
original disc is placed in the drive, all subsequent backups will be
read at 12x. Read speed of original game discs will remain
unaffected. Restart the system if you wish to read backups at 4x.

Thanks for the info

So i really depends on the media that my back up is on? i guess it will be trial and error to see which works best for me then.

Which version of Xtreme52 do I use for my Samsung MS25, "52x-ms25.bin" or "xtrem52x.bin"?
Cannot find an explanation anywhere.

Never mind, used the "Make Xtreme firmware.cmd" which showed the options.
It was confusing because I originally intended to copy the key manually.
