Windows 10: How to decide the exact size of both external hard drives used as RAID 0 with windows...

Using two USB3 external hard drives used as RAID 0 with windows storages spaces how to determine the exact total size of both for the pool ? for example the drive 8tb reported as 7.8 from properties and 7.6 from partition managerAlso what will happen if I used larger size and write exceed that pool size ? I use Windows 11

Windows 10 Raid 0

Before my Windows 10 Pro 64 Bit Installation, I went into my Motherboard's BIOS and set my two 2TB hard drives in Raid 0 formation. After my Windows 10 Installation, "this computer" sees my "C" drive as only 2TB. Windows 10 should recognize my Raid 0 "C"
drive capacity as 4TB. Why is windows 10 listing my "C" drive as 2TB? Windows 10 should have spanned the Installation across my two hard drives in RAID 0 formation. Did Windows 10 install only onto one hard drive? How can I correct this Windows Installation
to span across my two Seagate SSHD hard drives in RAID 0 formation?

 

Fresh Windows 10 install on RAID 0 drives with 64kb cluster size

Hi everyone,

I'm trying to perform a Clean W10 installation on my desktop.

However I'm using a RAID 0 drive structure and wanted to set a Stripe size of 128kb and an Cluster size of 64kb on the primary (SSD) drives.

I've searched a lot about the best way to perform a format with 64kb of cluster size on your primary Windows partition.

The best method I could find was using the DISKPART command in (elevated X: within the Windows 10 troubleshooter).

So I thought it was okay to assume that the RAID config is completely serparted from the partition config, and because of that I thought a format of the partition on my primary drive was never gonna affect my RAID config right?

• So firstly I deleted the previous RAID config (this also removes all partitions), set my bios to default settings and set the SATA boot mode to RAID, also enabled Intel Rapid Storage technology.
• After that I went to the W10 help and troubleshooting and created a primary partition on the (one and only Disk 0, because the RAID was allready in place, Windows saw this as 1 Disk). "create partition primary"
• I formatted that partition to have a 64kb cluster size like I wanted. "format fs=ntfs unit=64k"
• But when I tried to install Windows on it, it kept failing, even though it's the only Disk in the list and I have even loaded the Intel F6 Raid Controller drivers on the Disk, but still got that error that the Disk could not be used to install.

I'm assuming that 2 things could cause my problem.

• Creating and formatting the partition messed up the RAID config.
• Windows does simply not allow an installation on a non default cluster size like 64kb.

I would like to know what the problem is from a professional.

Thanks in advance!

 

RAID 0 is myth / RAID 0 is not possible / RAID 0 is a lie / RAID 0 is not possible on Windows 10 / RAID 0 does not exist

Hello, I am interested to know if RAID 0 exists or not? I have an external HDD drive which states RAID 0 is possible. However, I am not sure if RAID 0 is possible or not. There are no softwares which promotes RAID 0 creation. I have tried everything
and I do not believe in RAID 0. Prove me wrong!
