I have a 2-bay Mediasonic enclosure with two WD red drives in Raid 0, one 6TB, about 4 years old, and the other 8TB, about three years old. The enclosure has a USB3 jack and an eSata jack. I use the USB3 jack, but at one time I used the eSata connector and performance was the same. The drives are formatted ext4 and the Raid was created using the built-in Mediasonic software. The data is backed up nightly via rsync to a 16TB Synology NAS with two 8TB WD red drives, also in Raid 0.
I have had this setup for close to three years now, and it works great except when I try to read or write to the array and I have to sit and twiddle my thumbs for up to two full minutes waiting for the drive lights and the disk rumbling to stop. Once the drives are ready file transfers are reasonably fast - ~10-20 seconds to transfer a 2GB file. But then, even though I continue to do file transfers every couple of minutes, suddenly it will decide it needs to refresh itself, and then I have to stop everything until it finishes. I've been putting up with this for long enough. Is there any way to get this array to stop constantly refreshing itself? _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
