The ext USB3 hdd is your typical WD Passport 2 Tb. And it did retain the permission settings as I just find out.
I’m looking into the Vantec FW800 dock bays w/ the 4 Tb hdds. Not sure if these are the ones that will not preserve the permission setting. Didn’t pay close attention to the type of external drive being plugged in.

Yes. It would be nice but the risks are far too great.
You would need a pretty fast connection (at least 10 MB/s) upload stream. And I would never ever enable sharing. Hackers all over the world are scanning every minute and will monitor your PC stealthily. Huge security risk unless there’s a super strong firewall and deep packet inspection hardware/software to securely control the traffic. It will pretty much infect your entire LAN/WAN network within days. Try it now w/ your Mac. You’ll be getting at least 200-300 hits per day relating to screen sharing core services.

Apple’s Screen Share app is full of security issues that have not been addressed even w/ 10.9.2. People are literally scanning for that open port every other minute for a soft spot to exploit. For my Mac, there’re over 400 blocked attempts per day to get in to the port. I changed the WAN IP from various ISPs and still being scanned regularly. Luckily I have some pretty powerful firewall software and hardware to detect and fully block it. For most user it’s literally invisible and that’s very dangerous. You can be surfing the web for your bank account and other sensitive information and being monitored. It’s part of the core service background app and you’re pretty much giving everyone on the internet the chance to see what you’re doing on your screen. This is a catch-22 problem. Yes it’s good but also bad. So be extra careful when you’re connected to the net and enable sharing.

If you’re strictly in FCX 10.1 domain, then native FCP 10.1 import is fine. However, if you need to use the clips for other apps like Adobe After FX, Premiere, then I’d use the legacy FCP 7.0.3’s Log & Xfer to rewrap all of the P2 media. Whatever you do, always keep the original P2 media and its legacy 1980s DOS FAT-16 file structure! It works great in Premiere CS6 natively for time sensitively edits. But for real creative editing, FCX 10.1 rocks! Someday FCP 10.# can edit P2 natively and you wish the metadata rich original P2 media are all there.

I use both Premiere CS6 and FCP 10.1. However, majority of my creative edits are in FCP 10.1 and After FX CS6 for motion graphics. Talk about contradiction. I ‘m not familiar with Motion. But very comfortable with AE CS6. The problem w/ AE is that it’s linked only to Premiere CS6’s edit. 2 years ago I hated the first FCP X release but with the 10.1, things are looking very good so far and I’m using it more and more over Premiere.
Premier CS6 will take the native P2 file structures & AVC-I with full audio just fine. But for some odd reasons w AE, it won’t import the P2 contents folder but only the VIDEO folder with only the MXF files. The only way to get audio in AE cs6 is to Log & XFer in FCP 7 as a .MOV and both audio & video will import just fine.

The ideal raid level for uncompromised quality editing is RAID 10 (stripping with mirroring). Next economical solution for me is RAID 5, 50 (8 hdds needed), then 60. But you’ll need a 3rd party RAID card & external drive bays. Apple’s built in software raid 0 or 1 is OK but it’s not hardware accelerated like w/ the ATTO HBA or other SATA RAID cards. I’m not sure if Apple RAID support raid 10. If it does, I’d use that. The minimum is 4 identical hdds. You can have two dead hdds w RAID 10 and it’s still running (at half the speed). And there are vendor-specific RAID schemes that’s somewhat proprietary. But they’re optimized for video editing.
From the trend of the new smaller sized Mac Pro, putting four 4 Tb hdds in bay 1-4 and use the 2nd optical drive as the boot drive is probably the most economical solution with older silver colored Mac Pro. Eventually you’ll have to get to the Thunderbolt bandwagon and that’ll cost at least $5-10K for the new Thunderbolt enclosure. No thank you. I’ll wait at least several years for price to come down and design to stabilize. I’m not doing heavy 4K now. Still 1080p. 8 Tb of RAID 1 via Apple software RAID will do 1080p workflow just fine for many years to come. I’m actually getting very fast performance when editing w/ AVC-I 100 and Pro Res 422 HQ 1080p w/ the Apple software RAID.

You can use 4 Tb SATA-3 hdds with no problems. 12 Tb of unprotected RAID 0! But how long will it last is a totally different issue.
I have quite a few older Mac Pros and they’re still more expandable than the 2014 Mac Pros w/ Thunderbolt expansion. Not that it’s my biz, but putting a 4 Tb on raid 0 (stripping with no parity) increases the risk factor of 3x. Literally if 1 of the 3 hdds die, you’re out of luck by 3x. And I have purchased a significant amount of hdds for 4K footage. None of the 3 top vendors will last forever. They will fail at some point in the future. To me data is exponentially more precious than trying to save $160 for a 4 Tb hdd as a mirrored array. So far I can only put two 4 Tbs as raid 1 and the remaining 4 Tb for single 4 Tb hdd plus another for the OS & boot hd.

Right away, the OSXFuse bundled w/ the HP StoreOpen installer is a RED FLAG. I’m looking decades from now to be able to restore those LTO-6 media and I doubt OSXFuse will exist in 2030. Well, at least 5 years from now I’ll migrate to LTO-7 or 8. The LTO-6 drive and media will likely be sold to some one else. If LTO-8 can read LTO-6 media (which LTO format claims to have at least 2 generations of read compatibility), then I won’t have to migrate the massive amount of LTO-6 to LTO-8 as much. Ultimately, I’ll have no choice but to move to LTO-8. The massive 4K raw footage and countless other media sources are pushing the limits of LTO-6 now. It’s taking way too much physical tape archive storage space. This technical disclosure helps a lot to have a deeper understanding of LTFS & the LTO-6 format in general. The LTFS drivers compatibility headache is not something I want to experience w/ archive within years from now.
>>Next, you don’t MOUNT our tape drive as tapes shouldn’t be mounted – tape is not disk. The ATTO drivers are included in OS X and Windows out of the box. While it’s a good idea to update to their latest versions, it’s not required and the drivers from the HBA manufacturers don’t change the format that is written to the tape itself. And, the LTFS layer STILL depends on those same ATTO (or other) device drivers for proper operation. Unlike updating an HBA driver, changing an LTFS driver can mean the difference between a drive working or not working. It can also mean the difference between an old LTFS tape being readable under the new drivers or not.<<

Correct. On the Mac Pro hdd bay 1, there’re 4 separate OSX partitions fr. 10.6.8 -> 10.9.1. All of those years FW800 bandwidth was limited by the OSX. Data was fixed and no reformat done. I was archiving to LTO-6. Didn’t have a chance to benchmark 10.7 -> 10.9.1. This was a clean install because of FCP 10.1 performance.

I’m still evaluating the two apps. Only when one uses each after a good period, then its strength and weaknesses will be realized. Still only have a single LTO-6 drive for testing purposes. LTO-6 is not fast and it takes time especially backing up raw camera footage files.
On Pre Roll Post, will that PRP LTFS created backup be readable in BRU? I don’t really mind using LTFS. But the drivers needed is a concern. Because I use LTO-6 strictly for very long-term archival and not backup, my need is to be able to restore that data many years from now and not having to dig up obsolete older version of LTFS driver just to be able to restore that data.
I used to do tape backups in the late 90s w/ DDS-3. Data capacity scale was in the 18-50 Gb range. Hdd was a premium. Used to remember a 4 Tb Seagate external SCSI-2 drive costed about $1K. Nowhere close to the TB range as seen today at 1/10 the cost. DDS-2 was quite unreliable for media archives and literally abandoned it for almost 20 years. DLT was hot during the early 2000s. But didn’t really bothered to get into it because it was in the $4K range. Good thing I did not because DLT won’t be able to archive Tb of data economically. Fast forward to now I’m out of touch w/ the latest in backup apps & software. I prefer not to use turnkey systems. Prefer the software and tape drive solution only. But whatever it’s one thing for certain is that hdd will go bad on you at anytime – especially when it’s sitting on the shelf for years w/ out powering it. About 8 of my 150 3 Tb hdds (only after 3 years) are all experiencing sector read errors. I don’t know about LTO-6 media gone bad years even after full verify during the archive process. This hdd read sector error is unacceptable for my needs and LTO-6 is the only viable solution that is appealing in cost and overall flexibility.
