    External drive for backing up NAS -- USB3 vs eSATA

    The reason I keep at it: as I understand it, one drive in a NAS backed up to an external drive -- that has to be be more fault tolerant than two drives in a NAS. But people here seem to consider that an ill-advised solution, so I'm trying to understand if I'm missing something. Obviously two...

    External drive for backing up NAS -- USB3 vs eSATA

    Thanks -- but isn't your RAID itself then a potential single point of failure? I don't mean to be doom-and-gloom, genuine question!

    External drive for backing up NAS -- USB3 vs eSATA

    I would use the USB for regular backups of the NAS. This strikes me as more fault-tolerant as compared to two volumes in a two-bay NAS, no? With two drives in a single NAS, you still have a potential single point of failure. Whereas a 1-bay NAS with an external drive has two totally...

    External drive for backing up NAS -- USB3 vs eSATA

    Right -- so if I have a NAS, and if I back it up to an external USB drive daily -- if the NAS fails, then I can restore from the USB drive -- so perhaps I lose a day. With a two-bay NAS, if it's mirrored, and if one drive fails, then I don't lose that day -- but I still need to back up to an...

    External drive for backing up NAS -- USB3 vs eSATA

    I'm sorry, but I still don't get the point of the mirrored 2-bay NAS -- that is, assuming the NAS is being backed up to an external. If the NAS and/or drive within it fails, I have the external right there. (Additionally, I would try to cycle a second external off-site.) I'm sorry if I'm...

    External drive for backing up NAS -- USB3 vs eSATA

    It seems to me two drives in a NAS is more at-risk as compared to one drive in the NAS and one external drive. I agree that mirrored drives are more problematical as compared to two separate volumes, synched at some specified time -- but it seems to me if I'm going to have two drives total, it...

    External drive for backing up NAS -- USB3 vs eSATA

    So if I want to back the NAS up to an external, what do I use for the external? Some empty enclosure with both eSATA and USB3?

    External drive for backing up NAS -- USB3 vs eSATA

    But I'm still going to need an external drive to back up the NAS. (Right?) So I don't get the point of two drives in the NAS, given that 4-6TB is plenty for me. So I thought: if the NAS has eSATA, shouldn't I be looking for an external with eSATA (in addition to USB3). I thought the answer...

    External drive for backing up NAS -- USB3 vs eSATA

    Thanks, twice, with comments below... This is for my home, so I'm not worried about somebody walking off with an external drive -- in fact, I see ease of walking off as a *feature* (because I hope to get into the habit of cycling a copy off site). I don't really see a need for two bays (for...

    External drive for backing up NAS -- USB3 vs eSATA

    But isn't there a "USB per file" hit each time the NAS accesses a file on an external USB drive that there wouldn't be if the external drive were eSATA?

    External drive for backing up NAS -- USB3 vs eSATA

    Isn't the benefit of eSATA over USB3 going to be more prominent with lots of little files, rather than a big file? And, for example, if a backup program is doing tens of thousands of compares to determine which files need to be copied over, doesn't that come under the "lots of little files"...

    Is ~55MB/s "reasonable" over AC?

    Thanks so much -- so now I gather I still have to hope for data from somebody with a Mac and a NAS who can copy a big folder of small files over AC -- meaning, to have a sense of whether I should expect to do much better than the roughly 10MB/s read, 1MB/s write performance I'm getting with my...

    External drive for backing up NAS -- USB3 vs eSATA

    For example, I'm looking at NAS'es such as the Synology DS115, DS215j and QNAP TS-131. I really only need one bay, which I would back up to the external drive. The Synology DS115 and QNAP TS-131 both include eSATA. However the DS215j seems to have the same specs as the DS115 -- except the...

    Is ~55MB/s "reasonable" over AC?

    Had a chance to try again with Microsoft Security Essentials off on the PC. Interestingly, the read test went from roughly 7MB/s to 10MB/s, but the write only went from about 1.1MB/s to 1.3MB/s -- I did the read test first, and thought that was a decent change -- so then I expected to see an...

    External drive for backing up NAS -- USB3 vs eSATA

    I was thinking the external drive would ideally have *both* eSATA *and* USB3 -- so, with a NAS that has an eSATA port, I can get the benefit -- but I could always fall back to USB3 if I need to move the external drive to a computer/laptop. You think USB3 and eSATA are pretty similar? (Does that...
