![]() ![]() It has advantages over RAID 1, as you get access to more storage from the disks due to the striping. With RAID 5, you need a minimum of three disks for the algorithm to be able to rebuild the data when a drive fails. RAID 5 stripes data across the disks like RAID 0 but also uses an algorithmic calculation known as a parity function for redundancy. The drawback is that mirrored data means you will only ever have the storage capacity of the smallest disk in the array since the same data is copied onto each disk. This gives you complete redundancy with your data as long as one of your disks is still functioning. RAID 1 mirrors data across all disks in its array, meaning each block of data is written to each disk. RAID 0 is ideal for nonessential environments where speed is preferred such as testing environments or housing photos/videos that the user is comfortable losing in the event of disk failure. Data is stored in a segmented fashion on both disks for any given file so losing one disk is sufficient to lose all of the data stored on the array. This means that, when utilizing RAID 0, there is no redundancy. If there is data remaining after the last disk, the next block is written to the first disk and the cycle continues until all blocks are saved. RAID 0 breaks a file into blocks which are then written to each disk (first block to the first disk, second block to the second disk, and so on). Note: If you are using disks of different sizes in a RAID, each disk will default to the capacity of the disk with the least amount of storage space. ![]() Let's take a look at each of the commonly used RAID types and why you would want to choose them. Some are more focused on redundancy, others are focused on faster read/write times, and others still are focused on availability. These arrays differ depending on the RAID level that is used. RAID is a storage virtualization technology that combines multiple disks and puts them into an array. In this article, we will go over the most common types of RAID, their use cases, and how to configure software RAID on Ubuntu 18.04. Knowing the different RAID options will let you make an informed decision about how you should store your data. Our safety net now is multiple RAIDs and lots of backups.Choosing the right RAID (Redundant Array of Independent Disks) level for your storage array is essential to ensuring that your server meets your speed and redundancy needs. The last time I had a problem, it took them 48 hours to get back to me, but I solved the problem myself in the interim. In my specific case, when we've had problems with G-Tech (now owned by Sandisk), they have a user forum and a support line to assist. We have access to all kinds of freelance industry IT people here in LA, so if we hit a real roadblock, we'll pick up the phone and get somebody over in a few hours. This one experience - anecdotal, of course - was enough to sour me on the idea of ever considering OWC SoftRAIDs. My Resolve session wasn't lost because I did a daily session backup (on a thumbdrive), and I had backed up all the files to my own drive on the second day. And OWC's fix was to wipe the system and reformat it. I can tell you that at the facility I freelanced for where the OWC SoftRAID system died, the owner was on the phone to OWC for days and didn't get it fixed for a week. I don't watch YouTube videos on how to fix a toilet.Ĭlick to expand.I think you're misguided in characterizing every colorist on this forum as being someone unable or unwilling to hire an IT professional to diagnose a serious network storage or RAID storage problem. ![]() After all - they are TECHNICAL - and if they can't figure it out - then this product SUCKS ! But if that very editor or color grader can't figure out a technical issue by themselves with SoftRAID, or QNAP, or Synology (or anything else including EditShare, Facilis Terrablock, ProMax, OpenDrives, Studio Network Solutions, etc.) - that is NOT ok - they would rather DIE than hire someone qualified to help them. ![]() That of course, is ok - they are the idiots. Of course, these very users feel the same way, if they find a client that wants to edit a video or color grade a video by themselves, rather than hiring someone that appears on this forum. Of course, the real bottom line answer here, is that many of these users would rather kill themselves, than pay someone qualified to help them. I think anyone that is a single user, that wants to go with a NAS solution is crazy, unless they have multiple computers they need to share with. While I make my living with QNAP and Synology systems, there is nothing wrong with SoftRaid - especially for a single user. The amount of mis information on this forum (and most forums) never ceases to amaze me. ![]()
