If disk still works after 30 days, you can remove one of the older disks. Also all I/O operations are duplicated to 3rd disk and early failure might be detected. In the meantime not only old files are copied to the new disk. I am a proponent of a different approach. In a nutshell it recommends to take one disk offline and to add another thus replacing the first one. This post outlines the steps involved in maintaining the mirror. I click Disk\Format, select da4 and specify ZFS.ĭiagnostics\Information\Disks for da4 looks like this: 3 4 It works by reading and writing through the filesystem in a volume-dependent way. Based on Microsofts MIT-licensed Diskspd tool, 2 this graphical benchmark is commonly used for testing the performance of solid-state storage. I edit it to: set APM to 127, activate SMART. CrystalDiskMark is an open source disk drive benchmark tool for Microsoft Windows from Crystal Dew World. New drive da4 immediately appeared in Diagnostics\Information\Disks.ĭa4 appears. I powered down the system, installed new hard drive - there are plenty of empty positions available in the drive cages, powered the system up.

My NAS is configured with two mirrors for file sharing (over SMB) with other Windows computers: Maybe will use synchtoy to backup one drive to another. So I will be sticking with two single hard drives. For a workstation use scenario this makes storage spaces unacceptable for me. Random write performance however is dramatically deteriorated. Transition to storage spaces mirror moderately improves sequential read speed. Here is what I measured using CrystalDiskMark 3.0.3 圆4: A Microsoft Windows 8.1 Storage Space with two of the above hard drives configured as mirror.Kingston SSDNow V300 Series SV300S37A/120G 2.5" 120GB SATA III SSD - just because it was already there.I compared I/O performance of three drives: I just learned about Microsoft Storage Spaces and throught I would give it and ReFS a try. In this tutorial I show you How to use Crystal Disk Mark and how to measure the read and write speed of you hard drives, that is HDD, you solid state drives. Would be nice though if I could use those in a mirror - to make sure things are fast and tolerate hard drive failure. Given that I am running out of space on my video editing workstation, the choice was clear.
