How do you go about importing photos? I was playing with plugging in a card reader direct to the usb 3 port in the front but doesn't always seem to detect it. Would love to know what someone with more experience is doing!Vancouver photographerhttps://www.blogger.com/profile/07225030253431790492noreply@blogger.comtag:blogger.com,1999:blog-2644629870779379729.post-14981952899764812182012-06-26T03:44:34.640-07:002012-06-26T03:44:34.640-07:00Drew, just to let you know I posted a link to your...Drew, just to let you know I posted a link to your writings on QNAP and the DROBO on the Scott Kelby site. It appears that he's been having more than his fair share of fun and is looking for suggestions on alternatives.<br /><br />I'd be interested to know how you backup the large amounts of data a photographer would create. I can imagine some photographers having two such arrays that sync with each other - onsite and offsite, but that doesn't deal with data corruption. That normally gets dealt with by full and incremental backups etc. Do you have a process for this?Markhttps://www.blogger.com/profile/02808875632782157927noreply@blogger.comtag:blogger.com,1999:blog-2644629870779379729.post-15284192531823144372012-06-25T08:49:42.409-07:002012-06-25T08:49:42.409-07:00Hi Mark,

With RAID 10 you may be ok, you may not. I'd say Murphy's Law would be more prevalent than statistics.<br /><br />As for the statement about the speed i.e. a 10k raptor cannot saturate a gigabit connection - but an 8-way NAS definitely can. QNAP rate the 879's throughput at 1,345MB/s depending on what's inside so the disks will not max out before the connection.Markhttps://www.blogger.com/profile/02808875632782157927noreply@blogger.comtag:blogger.com,1999:blog-2644629870779379729.post-61940995684620318022011-10-27T02:22:33.817-07:002011-10-27T02:22:33.817-07:00I have to say I'm very pleased with the RAID 1...I have to say I'm very pleased with the RAID 10 arrangement<br /><br />I'm pleased I went that way<br /><br />Regards<br /><br />DrewAnonymoushttps://www.blogger.com/profile/10359795436606745114noreply@blogger.comtag:blogger.com,1999:blog-2644629870779379729.post-35426104382579022022011-10-03T15:30:14.769-07:002011-10-03T15:30:14.769-07:00@pixelmixture:
No, with a gigabit network you will...@pixelmixture:<br />No, with a gigabit network you will definitely max out the disks before the network if using RAID5 or RAID6, especially when writing large amounts of data (read operations is a very different thing). <br /><br />The fastest SATA disks that I know of is the 10K RPM Western Digital VelociRaptor which pushes around 100 MB/s sustained write speed, and that is still below the 120-125 MB/s you can push through a good gigabit network. Add in some time to calculate and write parity data to your RAID5 (or RAID6) and you are well below the network capacity.<br /><br />As for data integrity: Most people don't realize this, but you can lose half the disks in a RAID 10 as long as you are not losing both disks in a pair and still have all your data intact.<br /><br />Think about it:<br />RAID 0+1: A pair of striped disks. If you lose one disk in a stripe, the entire stripe is history (all four disks act as one big disk). Losing another disk in the SAME stripe does not make any difference - the other stripe is still OK. Lose a disk in the other stripe and you are screwed.<br /><br />RAID 1+0: A stripe of mirrored disks. Again, as long as you don't lose both of the disks holding the same content, you don't have to worry, all your content is there.<br /><br />So, when using 8 disks in RAID10 you can lose half the disks in the RAID, provided that chance and your good luck makes it the right four disks. On the other hand, having a bad day means that the second disk that fails is the one that holds the mirror of the first disk that failed and you are thoroughly screwed.Anders C.

This will slow down the write performance. Otherwise the raid volume will be damage after any kind of hardware failure or AC fail on your NAS system.<br />High-end RAID systems often comes with a battery unit to dedicate for the cache of the RAID controller.<br />NAS systems, also the QNAP, are software RAID based systems...<br />Cheers, MatthiasAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2644629870779379729.post-52747494437291394502011-09-11T07:55:15.921-07:002011-09-11T07:55:15.921-07:00A quick note regarding RAID6:
