Windows10 v1809 (2019): benchmark 240MB/s, Configuration: Not related to Storage Spaces, that is how plain disk sizes are presented in different units. A cluster with four servers has 50% storage efficiency and resiliency to two failures. Parity arrays are the most complex, in that metadata that calculates the contents of each drive in the array is spread across all the drives, so that if a drive fails we can replace the drive and recalculate the contents of the failed drive onto the new drive.

On top you create a dual-mirrored, tiered space. This significantly improved write speeds on my NAS, which is also running a (much larger) Storage Spaces array. Version 1803 bug (Windows 10 only) – Microsoft has unknowingly introduced an Explorer.exe bug with version 1803 that causes inconsistencies in regards with metadata file types.

You have the option … Continue reading Storage Spaces and Parity – Slow write speeds If you use the default cluster size of 16 KB, you are limited to 64TB! Likewise, a 5 disk Parity Storage Space created with the Storage Spaces UI, gets a column count of 3 instead of 5, so the utilization is again 66.7% instead of the Here’s what’s new and what it means to you.
