A technician is commissioning a workstation that is required to have mirrored storage, utilizing two 4TB drives that support one failure. Which of the following BEST meets these requirements?
You will need at least four disks to create a RAID 10 configuration and there must be an even number of disks. Note that it carries the same 50% disk overhead that mirroring does. I go with RAID 1
Remember : RAID 0 = 0/No Redundancy,
RAID 1 = High Redundancy, 2 or more disks.
RAID 5 = Same like RAID 0 but with parity, At least 3 disks.
RAID 10 = RAID 1+ RAID0, At least 4 drives.
This is according to Messer videos.
I corrected ChatGPT when its initial response was D raid10, it then changed it answer and agreed with my reasoning apologizing saying I'm right and that yes Raid 10 actually requires 4 or more drives meaning the answer is B raid 1since we only have two 4TB drives, this was the response i got-
My apologies for the confusion in my previous response. You are correct; RAID 10 typically requires four or more drives for its typical implementation.
In a scenario with only two 4TB drives and the requirement of mirrored storage with one drive failure tolerance, the BEST choice is:
B. RAID 1
In data storage, disk mirroring is the replication of logical disk volumes onto separate physical hard disks in real-time to ensure continuous availability. It is most commonly used in RAID 1. A mirrored volume is a complete logical representation of separate volume copies.

B. RAID 1 is the best option to meet the requirements because it provides data mirroring, which means that data is written to two drives at the same time, so that in the event of one drive failing, the other drive has a complete copy of the data. This provides data redundancy and ensures that data is protected even if one drive fails, which meets the requirement for one failure support.
It doesn't sound like the question is referring to an already existing workstation. It's saying that that is what they want the workstation to consist of. So, yes RAID 10 requires 4 disks, and that could be an option. So D is possible too.
A workstation that is required to have mirrored storage, utilizing two 4TB drives that support one failure. No speed or performance mentioned. so yeah Raid 1 is the best option.
This is a tricky question. A mirror is RAID 1, but the question states storage utilization (speed) which is a Stripe RAID 0. So, the answer is the best of both RAID 1 + 0
Except the issue is that RAID 1 + 0 (also known as RAID 10) requires a minimum of four drives, and the question states that there are only two 4TB drives, therefore making a RAID 10 impossible, so that answer is (B) RAID 1
