Has RAID, but how recoverable? Anyone know how easy or practical it is to restore when you have a crash?

Inside the enclosure there are two (2) independent hardisks. RAID 1 redundancy works just as expected, with one drive mirroring the other. It hasn't happened to me yet, but the literature says that in case of a crash. you simply replace the bad drive with a new one and the device will sync itself up, automatically. If the drive is under warranty, you call WD and they'll ship you a replacement drive. The case is designed so that the user can replace the drive easily. So, it's not marketing BS. It works as expected.

The short answer is yes. To elaborate, RAID isn't a backup scheme but rather a sophisticated scheme for building in fault tolerance. In RAID 1, if one of the drives goes down (assuming a 2 drive array) the NAS system can rebuild the data from the information contained on the remaining good disk. Though there is a certain "redundancy" of the information contained in a RAID array, the repository is still treated as a single source of data--if you lose the source, you lose your data. Thus RAID isn't so much a data backup strategy as it is a hardware backup strategy. Your data is kept safe by making sure the storage hardware doesn't go down. Though RAID helps with the problem of data loss, it doesn't address the issue directly. The best way to guard your data is to have multiple repositories kept in different places. For instance, on my computer I have three data drives. One is the main data drive, and I use backup software regularly to ensure the other two always mirror the first. Beyond the local drives on my computer, there's also a NAS box in the family room that I backup to. Moreover, I also have data stored in the cloud. Services like Box, DropBox, SkyDrive, Google Drive, etc. provide a useful amount of storage space for free (anywhere from 2 to 10 GB). For data you simply can't afford to lose, there's no better place to store it than on the servers of some big information technology company like Amazon. Using this scheme I can lose two or three sources of data, yet my data isn't irretrievably lost as there are yet other sources to draw from. Compare this against a stand-alone RAID array. If the array is lost in a fire, flood, or even stolen, the data is gone for good (barring some miracle). So yes, you do need a good backup plan beyond the RAID array. Hope this helps. Michael P.

This model does not have RAID 0. Only the very top end model has tha(UX301-XH71T I think)--Edit: Apparently I was incorrect, as the person in the comment reply below said this model does in fact have Raid 0 (according to "Properties" of the 2 partitions, OS and DATA). There is no option in the BIOS to disable this, which is unfortunate. Although RAID 0 using SSDs is not nearly as dangerous for your data as with a normal hard-drive since a failure is so unlikely.

I had not attempted raid yet, it does however afford me a score of 7.9 on win 7 x64 with a sata III SSD though....

In the past RAID has been a hardware supported function. I don't use this in a RAID setup as I only have two drives in it so far. You should view this as four separate USB to SATA bridges. Any RAID function you want to use will have to be 100% software implemented.

This is not a good choice for non-RAID. The Red drives are designed to stop re-trying bad sectors sooner than (for example) a comparable Green drive. This is great if you want the drive to continue operating while your RAID recovers the missing piece. If you don't have data redundancy, then you're more likely to lose data with a "NAS" drive.

It didn't come with any recovery disk, but since this computer comes with windows 8 it offers a easy to use recovery/restore tool under the settings app. you can reload your whole o.s. like new.

I have 3 TB drives in a raid 5 configuration. No issues yet. We use it primarily for time machine backups.

If the device (Synology DiskStation) failed then you would be able to recover the data by either mounting the drive to a Linux system or by loading the drivers for EXT File Systems in Windows. This is of course assuming you are using either a RAID1 or JBOD setup (RAID 0 would require reconstructing the array). If the drive fails and you have a RAID 1 array setup then all you need to do is follow the steps linked here: http://www.synology.com/en-global/support/tutorials/485

That is the theory of a RAID 5. I had a 4TB drive fail after a month on duty. Western Digital immediately sent me a new one, I plugged it in and it took about four days to re-establish the full RAID. My 16TB with 12 TB usable space on RAID 5 was loaded with 4TB of records. So, if you want to upgrade your system one drive at a time, better be patient.

You should keep a separate backup on a non RAID disk. RAID is not backup. It would have been a lot cheaper to keep separate backups with one off-site. You are lucky you got any of the data back. Three rules of computers: 1. Backup 2. Backup3. BackupIt is not a question of if a machine will fail but when. So, no, there is no assurance.

Mine did not but there is a way to download a recovery file.I have been happy with my computer. It really has not given me any problems.

That's the answer I'm looking for. I have tried to recover a very important file myself with no luck so far! Nothing in the instructions that even gets into recovering files. I am afraid we may have lost them forever!

No, this isn't a RAID (although there is a version of this that does support RAID). I bought it as a replacement for a couple of hard drive docks that were giving me trouble and it worked perfectly and other than Windows having to re-recognize the drives Windows never even made a blip.

I agree with David, you can set it to Raid 0 for full storage space use. I prefer using Raid 1 for protection even though you drop the usable space in half. I like having my data replicated in case of failure.

I'm using it with Win 8.1 and no problem making backup files. Have not had to recover.

I am not familiar with the drive you have but if the connections match, give it a go. In my situation, it was the PC that crashed with a healthy hard drive. All I had to do was remove the hard drive from the PC and hook it up to Apricorn and I was back in business. I wish you all the luck!
