Ranier offers excellent advice. Promise supplies the truly horrible Toshiba SATA drives. At some point, you should swap out all the drives for WD RED, or HGST NAS drives – both which are not very expensive and certainly more reliable.
I would not worry about the Maintenance Routines. Even with the Toshiba drives, the rebuild process works quite well.Bob Zelin

Hi –
I may have done this once or twice before. You should google search me.Bob Zelin

this works wonderfully. Thank you for showing me this.
All bandwidth for drives, and networks, from video companies like AJA, Blackmagic, etc. all use speed tests that show MB/sec. Ethernet or 10G ethernet bandwidth is based for video people in MB/sec. So those are numbers that I can easily relate to. Showing Mb/sec or Gb/sec always requires a conversion.

this is a very nice app, however, while it’s free, I find it a little inconvenient that it reports the codec speed requirement in Mb/sec, instead of MB/sec.
So when I select (for example) 4K UKD, at 23.98 frames per second, with a Codec of ProRes, it reports back 468 Mb/sec.
I then have to use Google to convert 468 Mb/sec to 58.5 MB/sec (not something I can do in my head).So I am greatful that this app exists, and is more comprehensive than AJA Data Calc, but it’s a little inconvenient.
I know – it’s FREE, so I should just be happy, and not complain.Thank you for posting this.

I would know nothing without Small Tree. They taught me everything. With that said, SNS makes very nice products.
Many of the companies that exist today, would not be here if Small Tree did not figure things out a long time ago.Bob Zelin

you said that you own a 5,1 Mac Pro. That computer has 4 slots for SATA drives.
Buy a 1TB SATA drive for $50 bucks. Clone your existing OS X El Capitan drive to the new 1TB drive (use Super Duper, Carbon Copy Cloner, etc.). Boot up on your clone. Upgrade your clone to Sierra when it comes out. See what happens. If it does not work, you have your original boot drive. If it does work, but your other applications won’t run on Sierra macOS 10.12, then keep both drives in the computer, and boot up which ever one you need.Why would you risk losing functionality of your entire system, when you can simply create a clone boot drive, and try it.
Is 50 bucks too much ?Bob Zelin

why do you think G-Tech should be avoided ?
G-Tech is great, so is Cal Digit.But ALL drives fail, so you will need a backup system, in case of failure. If you cannot afford a backup system, which includes simple single drives, then you cannot afford to do a documentary. If you lose your footage, someone will
get shot.Bob Zelin

any of the 10G QNAP, Synology, or Netgear ReadyNas products will work for you.
You can hookup multiple computers and not need a switch for just the 2 – 3 users.
But if must be one of the 10G products they make. Are you the one that will configure this ?Bob Zelin

Randall:
I didn’t realize that I could partition the NAS in such a way as to replicate the volumes that I currently use for music and video production in order to preserve the directory paths.REPLY – you do not need to create partitions. You simply create a shared folder with that exact name of your drive, and when you mount, it will appear with that name, and the path that you have used before. Your software will not know the difference – it will think that it’s the same local drive.
I think the million dollar question is whether a NAS on a 1 Gb network can compete with the speed of a DAS. The Synology DS1815+ for example, has about 450 MB read/write with Raid 5, whereas the Caldigit T4 has about 750 MB read/write using Raid 0. I am currently editing primarily in 1080p but plan on incorporating 4K soon.
REPLY – a 1G connection will give you 100 MB/sec. To get 600 MB/sec, you use a thunderbolt to 10G Ethernet adaptor like a Sonnet Twin 10G or Promise SanLink2. Then you get over 600 MB/sec.
I had considered a QNAP TVS-871T for its Thunderbolt interface (albeit more expensive), but would like to avoid the added expense and complexity of setting up a 10Gb network. I suppose though if I had a TVS-871T, I could connect my IMac directly to the unit via Thunderbolt, and then chain my external Thunderbolt drives directly to the NAS in order to gain speed both for production and backup.
REPLY – it is not complex to set up a 10G network. Even if you use Synology, and want these speeds, you need 10G in the Sinology, and 10G on your client computer. Same with the QNAP, or any other product on the market.
If it’s too “complex”, you hire someone to assist you. This can all be done over the internet.
While you can plug in the 871T into your iMac, you are best off using a 10G connection with the Sonnet 10G box, allowing for other computers to connect as well. This way, you can just keep your Tbolt drives on the thunderbolt buss of your iMac, and you will get the crazy speeds. The 871T is cheap.One more question: I want to put my NAS system in my network closet, which would require an approximately 25 foot Thunderbolt run. Is that going to deteriorate the signal?
REPLY – You can run the ethernet cable up to 300′ away. Specifically, 55 meters with Cat6, and 100 meters with Cat6A.
If you want a DAS connection with thunderbolt, you use a Corning Optical Thunderbolt 2 cable, and you can go as far as you want without issue.You know how to contact me if you need help
