How to software RAID 0 on 2 partition of the same drive (for dual actuator drive speedup) under Windows
Hello!
I just got a Seagate Exos Mach2 dual actuator sata drive and am trying to create a RAID 0 out of the two halved partitions in order to mimic what the SAS version does with the two LUNs and basically double the potential speed by using both actuators simultaneously.
I cannot however seem to figure out how to create this striped volume, as the disk management options are all greyed out. I've tried switching the disk to dynamic as well, and it's the same thing.
I'm not too sure how to achieve this, since RAID usually requires disks and not partitions, but it's definitely achievable under Linux: https://forum.level1techs.com/t/how-to-zfs-on-dual-actuator-mach2-drives-from-seagate-without-worry/197067
Anyone know? The limitation being of course, Windows.
You're viewing a single thread.
for testing, you can create two VHD virtual disks on the drive and mount them as RAID0. This way you can try out if the method have any benefits or not.
however I doubt about the method, because your partitions, or VHDs are linear. One is at the beginning of the disk and fast, other is the second half on the disk which has slower access speeds and also the throughput is slower.
The benefits exist for sure, due to the SAS version that exposes them as two different drives, which you can easily raid and get the full expected 500mb/s. The SATA version, which I have, and cheaper ofc, doesn't do it that way, even though you can split the drive in two and independently, both run at the max regular 250mb/s speed, I'm trying to "hack" the same solution to extract the benefit, but it might indeed not be possible due to the limitation of them being partitions and not drives.
