I just got a new ssd and i dont if i should use MBR or GPT.
It's a 150gb ssd samsung.
This is kind of like the ancient question: FAT, FAT32 or NTFS? IMO, use the latest - if you have UEFI ROM and will be installing Windows 10, then go with GPT. Set UEFI (BIOS) to boot with UEFI and Legacy + AHCI and you're good to go. Just my opinion as a 70 years old retired EE who's ben around since DOS, but there it is.
