Interval, which is a bit of a nuisance, but the work would be very I do not bother with any photo or video editing in the Is about 7MB/s, yielding an ETA of 60hrs. ForĮxample, I have 1.5TB mirror set, and I find that my average update Using the average from the sixth step, and the size of the disk, youĬan now predict the total time before the mirror set is 100%. Just below - use the 'average' to see how fast the disk is updating. Question of trial and error, but the read/write bytes will appear ![]() The green menu item to select Physical Disk, then Disk Bytes/sec, and In the LH window, click on Performance Monitor. Hit the startīutton, type perfmon and then you can start the perfmon.exeĪpplication. You can observe the activity using performance monitor.

If you have occasion to restart the system before the resynch is Any activity on the mirror set will slow things I have 80MB/sec disks, but they resynchĪt about 7MB/s. Windows 7 (one can always hope that things may be different in W8) synchs atĪbout 10% normal disk speed. The resynching applies to the whole disk, not just one partition or Update can cause resynching by applying updates to only one disk of the set. If one has to hit the power buttonīecause the system is completely locked, or it goes down in a power outage, then one will have one's Raid 1 In W7, mirroring will yield higher performance than a solitary disk, but resynching could be handled better.Ī Raid 1, mirror set, will always need to resynch after any It will occur whether HW or SW raid, but these notes relate specifically to XP/Vista/W7 software RAID 1. Any implementation of RAID will potentially suffer from this resynching downside. You may go for months, years before resynching occurs, if so, you are lucky. Here is a summary for anyone searching on this thread and has concerns about this problem.
