    Advice for external hard drive

    jaybee_uk Level 1

      I need some advice for an external hard drive solution. I usually edit single narrative short films using; 1080 footage, 2.7-4k GoPro footage,  sRAW / mRAW / RAW timelapse sequences. The apps I use are; Lightroom, Photoshop CC, Premiere Pro CC, After Effects CC. 

       

      Currently I work with a 2011 i7 iMac and store all my working assets on a 2TB USB external drive. This (obviously hugely inefficiently) currently serves as both an archive for my assets and a scratch disk for whatever I am producing, mostly timelapse sequences rendered from AE and edited in Premiere Pro.

       

      1) This disk is now 3/4 full so I need more storage space for fresh assets.

      2) I need some way to regularly either backup or duplicate this storage archive, possibly using a RAID 1 system.

       

      I've just ordered a 5k iMac and my dilemma is now what external storage solution/s will best fit my use case. I'd like to have good performance, but I also would like to have some form of redundancy.

       

      I was thinking of buying a 8TB Thunderbolt RAID system (either WD to G-Tech) and set this as RAID 1 so;

       

      a) I will have 4TB or storage space which should last me for the next couple of years,

      b) my working files will be protected from potential HD failure.

       

      ...however as I understand it this will not perform optimally in regards to a scratch disk as essentially the drive will be constantly duplicating the data which will slow things down.

       

      I figure the optimal solution for me is to buy a RAID 1 system for storage and a separate drive to use as a scratch disk. Unfortunately I can't really budget for 2 x RAID drives.

       

      Would a single RAID 1 system work for me? Can anyone recommend a setup which would serve me best?

       

      Any advice appreciated.

          I'd suggest Areca's ARC-5026 4x drive external RAID enclosure. It is more expensive than your other options, but here's what it can bring to your party:

          • USB 3.0 and Thunderbolt connectivity (unfortunately this is pretty rare and would allow you to plug into your old Mac and your new iMac 5k)
          • RAID done "right" (with a decent controller) and including RAID 5; you would put you existing disks in now, and grow down the road

           

          Here's a link of various external Areca solutions available at Newegg:

            Looks good JE! Thanks for the link. I wonder, if I would buy the Areca with 8 disks, can it also be configured into 2 sets of 4 disks in RAID5? I want to have my files really physically backed up / existing as 2 real copies. A single RAID 5 setup protects against disk failure, but not against accidental loss of files. So for my next workstation I am planning two RAID5 sets (or one JBOD set + one RAID5 set). So I could buy 2 separate enclosures of 4 disks with RAID5 option. Or maybe just one Areca 8 disk solution that can has it disk drives configured in multiple ways?

              Jim, many thanks for the feedback. While that looks like an ideal setup, my budget can't stretch that far and it's possibly overkill for my current requirements.

               

              After a lot of research and working out what would work best for me, here's what I've gone for:

               

              Working assets drive

              LaCie d2 4TB Thunderbolt 2 (up to 220 MB/s) (up to 1150 MB/s with SSD Upgrade).

               

              Clone

              WD 4TB Elements Desktop Hard Drive (up to 126 MB/s).

               

              This way I have satisfied my requirement for more storage space and have an option to upgrade the D2 for insane speeds if I feel I need to in the future.

               

              I've decided to continue my current backup process of doing regular clone backups as opposed to using a RAID 1. For this purpose the 4TB WD will suffice.

                Hi Jaybee,

                Sorry I interrupted your thread with my own question.

                Two important questions are:

                1. Did you order your new Imac with a SSD or HDD and which size

                2. 2TB external drive which you already have - is it USB 2 or USB 3 speed?

                 

                One route which may be interesting, especially when on a smaller budget, or just want to make use of hardware you already have would be to make use of cheap and flexible hard drive docking stations like this one:

                Amazon.com: Plugable USB 3.0 SuperSpeed SATA III Lay-Flat Hard Drive Docking Station (ASMedia ASM1053E SATA III to USB C…

                And this in combination with an external harddisk set that has at least 2 drives so you can put it in RAID0. Your setup would look something like:

                - Imac 5K for OS & Applications

                - 2 x HDD in RAID 0 for your media. like the "WD My Book Thunderbolt Duo 4GB with RAID 0 & 1 support for $499"

                WD's My Book Thunderbolt Duo External Desktop Hard Drives

                - 1 x 2, 3, or 4 TB drive in a docking station for backup of your RAID 0 media drive, and as export  drive when you make your final renders

                - If your old 2TB external drive is USB 3 you could use it for scratch drive. When it is USB 2 it is probably better to include the scratch drive on the RAID 0 drives, or on the Imac5K drive if you choose it with an SSD.


                In this way you will have both a fast video editing multiple harddisk setup and a full backup solution of your files on two separate locations / instances.
