The Synology NAS does not have an eSATA port, but it does have a USB port, so I could probably attach the Mediasonic to it. And I agree that doing so might make the connection more stable - the NAS is across the room, while the Mediasonic is on my desk where stuff gets moved around a bit. However, I have long been impatient with the speed of the Mediasonic; moving or renaming a file can take over a minute while the drives whir and the lights dance. I lust for SSDs to replace the two WD Red Pro drives in it, but the cost of 16TB of SSDs always makes me discard the notion. If I attach the Mediasonic to the Synology I wonder about access time compared to its current USB 3 connection. During the restore from backup the GUI (Nautilus) gave me a popup with continuous information on the progress, and it reported a steady 115-116 Mbps transfer rate, so that is apparently the max that my home ethernet can do. I have been shopping for a new computer and I'm currently looking at a Thinkpad P72 (not yet available in the US) or a P71 that I can buy right now. Both come with Intel Thunderbolt 3 USB-C ports that are capable of 40Gbps, compared to the 5Gbps of my USB 3.0 connection or 3GBps of eSATA. Then again, the WD Red Pro drives are SATA-3, which are rated at 6Gbps, so until I go to SSDs there wouldn't be much to gain. And the only faster enclosures available are Mediasonic rated at 10Gbps. What would be really cool is 16TB of SSDs mounted inside the laptop itself. >If attaching it permanently to NAS is not an option, autofs with >reasonable timeout avoiding the DAS power saving mode, instead of mount >in fstab, would probably help too. The Synology is mounted by a line in fstab, but not the Mediasonic. I have thought of doing so, but haven't bothered; it's trivial to mount it with the GUI. But if doing so can increase access speed I'm all for it. ___ PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
[PLUG] Tracing delayed email
Not frequently, but often enough that it's noticed, an email I send takes very long to arrive at its destination.

Re: [PLUG] How to restore external drive
It seems that it would be safer to have the DAS array attached permanently to your NAS and access it over the network. That is if your NAS has eSATA port. That way it would be permanently attached like internal drives and that should avoid these type of synchronization errors - Especially when you use it as RAID0. RAID arrays, especially in striping configuration, do not like to be detached or put to sleep without proper sync and umount. If attaching it permanently to NAS is not an option, autofs with reasonable timeout avoiding the DAS power saving mode, instead of mount in fstab, would probably help too.
