If using in RAID 1 and one HDD fails, do I just plug a new HDD and the enclosure will mirror the good HDD to it?

Alex, The answer to your question is yes. Make sure both drives are the same size and same make, the drives must be identical. Earl

Not 100% sure but it worked for my raid 5. I would think it works the same.

That's the way it's designed to work. Otherwise, there's no point to having a RAID array and you might as well sync two hard drives. I own this enclosure and like it very much but I've not experienced a hard drive failure yet so I have no personal experience. Apparently, Mr. Morrissey does. I do not think the drives necessarily have to be identical, but the RAID array will end up being the size of the smaller hard drive.I would also note that the StarTech enclosure does not support RAID 5 (only 0 and 1) so Showman's RAID 5 could not have been in this StarTech enclosure.

careful -- 2x 4TB in Raid 0 would mean total data loss in the event of 1 disk failure. You are essentially doubling your chances of complete data loss. You are far better to use RAID1 (even though it gets you just 4TB of disk storage), or get a different NAS to add multiple drives (3x 4TB in RAID5 = 8TB, or 4x 3TB = 9TB) so that you can have redundancy. MTBF shrinks when you get into bigger disks... and then doubling that risk by using them in RAID0 is asking for danger. Now, if you were just going to set up two separate 4TB drives, then that wouldn't be as big of a deal. Still no redundancy, but at least failure on one disk doesn't mean data loss on both.

I don't think this will work. I assume your dead enclosure had a RAID configuration (which will require the disks to be read together). This unit does not do RAID.

No. Once you do the initial setup, if you add a second drive you can not set it up to run in Raid 1 without having to format the drive.

Hello Edward. You definitely can. In this case you should select SHR RAID type, so you can add the other disk later. I personally would recommend you to begin with both disk, because, with them you could use SHR or RAID 1 (mirror disks) so in case of failure of one of the disks all the information will be in the other one. This is one of the main features of a RAID system that makes it a better option than an external USB disk that you should use from the very beginning.Hope it helps.

Using X-RAID is the only way to make that work. But you are limited to 1 volume, if you want more than 1 volume you would turn off X-RAID but you cant go back without reformatting your drives. X-RAID will manage your redundancy

Yes, do the setup for RAID1 which is mirror drive.When you install the disk, you will see what capacity you had.With RAID1, you get the capcity of one harddrive.you can go to Synology website and get the details.

That really is about all there is to it. Of course, during the process your new drive will be appropriately partitioned, formatted, etc...but it is all handled by your RAID software. Just be aware that when you buy a replacement drive, if you buy one that is larger or has a faster rotational speed than your remaining drive, the performance of the replacement drive will be limited to matching the size and speed specifications of the remaining drive. (Don't buy a 4 TB drive if the remaining drive is 1 TB...it will work, but you will lose 3 TB of usable space.)

I set mine up with one other one in a RAID 1 configuration and it works great and has for several years now. Not sure if it works for one RAID configuration it will work for any RAID configuration, but probably.

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

As far as I know from the documentation, if you place the drives in with the dip switches set to JBOD then you should be fine. I'm not sure how well that functions since I was mainly interested in the HW RAID.

Using 5 drives without redundancy is just asking for problems... I would venture to say that one of those drives is going to fail within a year. I have a 2x 2GB RAID1 system for the past 4 years, and had to re-sync them once. In the last 15 years I've had ~5 drives crash or get corrupted. Never again will I leave valuable data in only one drive.

Either is possible, it has two drives in it and can be used as Raid 1 or you can use them as Raid 0. From recollection it comes preconfigured to be used as Raid 0 - taking more advantage of the the thunderbolt interface.

Actually tried that with one of the drives. Was a pain in the ass, and in the end it resulted in 'nada'. The switched controller reported the same error. Did have a little luck with another approach. Got a portable unit that accepts a hard drive on one end and has a USB on the other. With two of these, I was able to use an old CD copy program to make a copy. Took some errors on the way but worked well enough that the new drive had about 99% of the data. Since then, RAID 5, and while other drives have failed, no more dta loss.Hope this helps.

I'd STRONGLY recommend against using an old drive in the device. By using one not from Synology's list, you risk poor performance. It would be a drag to set it up and then have slow performance. Don't use an old drive -- they all have a maximum life, and yours could be close to the end and you would never know. Since you're putting it in a 1-bay enclosure with no redundancy, you want to install the most reliable disk you can.

If you set up as a raid mirror you can hot swap the drives as long as one of the 2TB drives is working to copy your data from. Raid must be mirror not stripe.

Yes either raid 0 or raid 1 is possible. I would not recommend this product though.
