since Samsung made drives are also sold by other brands (like Sony or Philips for example), I thought it would be a good idea to have a list that helps checking if a certain drive is a Samsung clone, and which also provides information about crossflashing success (A successful crossflash is a good indicator for same hardware). This list will be part of the FAQ.
And please, do not ask the question about "how to crossflash" since this is covered in the FAQ, and there are also several threads about this giving detailled information.
Let me start with the drives I own myself:
SH-S182D = TS-H652D = Sony DRU-830A = Philips SPD 2412T
Comment: Best firmwares are TS-H652D KC03 or Philips SPD 2412T P1.5
SH-S203B = TS-H653B
no crossflash attempted
SH-W163A = (nearly) TS-H553A
Crossflash kills the drive!
TS-L632H (slim) = SN-S082H
Crossflash successful from D300 (Dell OEM) to SB01
