I’d like to buy two HE10 10TB 4Kn drives, Model #HUH721010ALN600. This model is a native 4K HDD where both the logical and physical sector size are 4,096b. One will be for data, the other for backup. I’m building a new system using a Z270 UEFI motherboard which will boot off of a Samsung 850 Pro with a fresh install of Windows 10. There will be no RAID implementation. According to Samsung, the Pro has a logical sector size of 512b and a physical sector size of 4,096b (aka AF 512e). Before I buy I’d like to know the following:
- Will the differing 512e and 4Kn formats on the drives potentially cause any compatibility or performance issues?
- I understand that 4Kn requires UEFI, which this motherboard has. But will I be able to format the Samsung boot disk as MBR in CSM mode, or will it need to be formatted as GPT?
- Will the 4Kn drives need to be formatted GPT?
- Do I need to be concerned about the 4Kn compatibility of the onboard SATA controller?
- In this setup, are there any advantages of going 4Kn (rather than 512e) on the HSGT drives?
- In this setup, are there any disadvantages of going 4Kn (rather than 512e) on the HSGT drives?
- Are there any other potential issues I need to be aware of to avoid a nasty surprise?
Many thanks for your guidance.
