Scarlet Posted August 2, 2012 Share #21 Posted August 2, 2012 Advertisement (gone after registration) There is several forms of raid. The two most common forms raid 0 and 1 require only two drives. They are referred as mirrored and striped. Most people choose striped because of capacity and speed, but the down side is redundancy, there is none. One drive dies and you lose it all. Mirrored is fully redundant, you can loose a drive and keep on working. But the down side is capacity, it's halved. If you want to talk raid 5 or 10 you are in a different category. Actually it is the other way around. Raid 0 is striped, raid 1 is mirrored. RAID - Wikipedia, the free encyclopedia Link to post Share on other sites More sharing options...

Scarlet Posted August 2, 2012 Share #22 Posted August 2, 2012 Still, I back it all up with Apple Time Machine every hour... I tried TM for a year and found it utterly useless in the end. Sure, the feature of backing up every hour, then saving daily, weekly and monthly backups is good for those who need that type of traceability in their work. But the fact that TM seemed every few months to "forget" the how the backup was structured (TM uses various types of links so as to obviate the need to copy each version of a file as soon as it changes, thus saving space but requiring a very complex database to keep track of everything) which required TM to completely verify the integrity of the backup by doing new and entirely full backups (meaning all previous backups were destroyed) made me ditch it in a heartbeat. For virtually every user cloning drives using "smart backup" with SuperDuper is entirely sufficient, straightforward to set up and very reliable.

swamiji Posted August 2, 2012 Share #23 Posted August 2, 2012 Actually it is the other way around. Raid 0 is striped, raid 1 is mirrored. RAID - Wikipedia, the free encyclopedia I did not place it in any order, that was not my point. The point is not to expect redundancy from striped raid, and what the price was for redundancy. That wiki is lacking in so much information its amazing. Link to post Share on other sites More sharing options...

Consistency is pretty important esp. when giving advice. A simple thank you for correcting would have sufficed. Whatever one may think about the wiki it is useful as a starting point for ordinary users. Link to post Share on other sites More sharing options...
swamiji Posted August 2, 2012 Share #25 Posted August 2, 2012 If you want solid performance with maximum dependability raid 10 spread over two frames with dual power supplies. Not very portable but as solid as you can get. Pretty much everything else is a compromise. Link to post Share on other sites More sharing options...
algrove Posted August 3, 2012 Share #26 Posted August 3, 2012 It is not automatic, but I self-mirror with my 2x480 SSD OWC drives that I put into tiny OWC cases that weigh maybe 8-10 ounces total for both. While traveling this gives 3 times redundancy-2 times with the SSDs and the third time with original SD card itself. So far I have never run out of storage, even after 3 months on the road shooting DNG + JPEG Fine. Link to post Share on other sites More sharing options...

You install whichever 3.5" drives you want and in RAID 10 it should be awesome. I am just waiting for the 4TB drives to drop in price a little more. Then I will get 4. They are now at USD298. I seldom buy anything other than Hitachi, but not the green ones. Link to post Share on other sites More sharing options...

I seldom buy anything other than Hitachi, but not the green ones. A week or so ago B&H took another $40 off per drive from their regular price of $298.99 Hitachi 4TB Deskstar 3.5" SATA III Internal Hard 0S03355. I couldn't resist that currently low price of $259. So I bought 4. They work just fine. Great data rates as well. Link to post Share on other sites More sharing options...
algrove Posted August 17, 2012 Share #29 Posted August 17, 2012 Just went on the B&H site 2 minutes ago and the special price has ended-now back to $298. Link to post Share on other sites More sharing options...
