Thanks for your quick response and you are about the fifth person from this forum to tell me that. So, I'm not hard headed and I value the opinions of my HH family, thanks again.

I like RAID 1+0 also (long the favorite of data base administrators) and in some cases, it will tolerate a double drive failure also (depending on where the two drives fail). The downside is that you only get 50% usable storage of the total capacity you pay for. As an alternative, if you don’t need the extra speed or capacity that RAID 1+0 provides (a single drive is large and fast enough for your needs), you can simply use RAID 1 or simple mirroring.

Regarding RAID 5, there is no redundancy drive - the parity is rotating across all drives such that the parity is always on a different drive from the block of data and as mentioned, you can add another drive to support dual drive failure without data loss so called RAID 6) The advantages of RAID 5 are higher utilization (a 3 drive RAID 5 provides 66%, a 4 drive, 75%, and so on) and the ability to serve different files to multiple users simultaneously, hence the reasons most corporate/enterprise servers are RAID 5. Like any RAID system, you are vulnerable to a second drive failure during a rebuild, which can take a very long time with large drives.

Actually, the best choice for performance with large files and the highest utilization is a RAID 3 (byte striped with a separate parity drive) or RAID 4 (blocked striped with separate parity). RAID 3 is hard to find, but there is at least one consumer grade system that offers RAID 4 and of course, if it fits your budget, there is NetApp, THE enterprise grade NAS company. If you can find a used one at a reasonable price, THAT is a great solution. I bought one used and ran it for 10 years in an un heated, uncooled basement (in addition to its original service) without so much as a drive failure.

Okay, thanks for the information. As I have stated with some of my other HH family members.....I have a lot to read and decisions to make here pretty quickly.

When I built my photography PC I set up the internal drives in a raid/mirror configuration with 2 4TB drives. It works great and if one drive goes down I have 2 spare 4TB drives to use to swap out the bad drive.

It would be nice to have an external raid system but I think I am going to do a cloud back up this summer.


Okay, thanks for the information, I've got some homework to do for sure.

This answer displays a lack of knowledge about RAID levels and systems! RAID 1 is a very robust backup system albeit at a cost! Depends upon how anal one is about backup, and I'm admittedly pretty anal. Although I prefer SSD systems for files used frequently, a good RAID system can backup decades of data as does mine. As with anything else, there are tradeoffs between speed and security, but a RAID array, in a good NAS system, such as Synology, can be a wonderful asset. Best of luck.

I'm getting a headache from all of this. I'm admittedly anal about this myself and am frankly getting a bit confused on which way to go. I'm tossing the idea of adding an additional RAID 1 to my desktop and using Carbon copy cloner to have two totally separate disk copies.

Well I do this stuff for a living. All RAID 1 does is mirror the drive. Useful for a critical system as the system will not shut down if one drive fails. Not really very useful for a backup. Not that a backup strategy shouldn’t have some redundancy, but having a back of the backup in the same hard drive enclosure makes no sense. Your secondary backup should be offsite, which these days usually means some sort of cloud backup service.

Carbon Copy Cloner is a great Mac backup tool if you want a static backup. I use it to clone an existing drive before doing major system upgrades or moving from an older computer to a new one. I've had to restore clones to new drives twice over the years.

I also used CCC to copy a single setup to five different Macs at work about 20 years ago. It worked well, and saved lots of time! Software licensing and registration issues took a while to work out, but MS and Adobe worked with us.

Can I private message you for some additional feedback?

I have off site as well.

For UHH members with more than one device that needs cloud backup, iDrive (which lets you backup a set amount of data -- prices start from $3.99 per year for 10TB introductory rate -- from multiple devices) may be a better option than Backblaze (which allows unlimited data from one device).

Hello my HH family, Would anyone have any knowledge of the OWC manufacturer? I am interested in OWC because they are based here in the U.S. and they were recommended by Glyph which is the system that I'm currently using. Your suggestions would be greatly appreciated.


OWC supplies a variety of computer storage solutions, and that they recommend GLYPH, as a source for drives, is a good thing. I have been a GLYPH user for many years, although for audio editing/back-up. For what ever reason they are the preferred drives for artists and media producers. I recently ordered, from OWC, a 2TB SSD to replace a failed HD on my ancient MacPro 1.1. OWC was recommended by the outfit I normally go to for Mac service. They steered me to a compatible drive, and the correct SATA adapter to fit into my old, but reliable, computer.

For photo BU I have chosen external SSDs such as SanDisk Extreme portables. They are compact and easy to throw in your bag. Also, they are large enough so you can't easily lose them like Thumb Drives, or SD cards. many manufacturers are offering their own versions of similar items.

You have some good advice from some very experienced photographers to work through. My advice is to pay particular attention to Gene51 and Trix- they know their stuff.
