I've never used a raid setup before. Will this make exact copies of my drives? So I no longer have to remember to copy data between my drives.

Jim, this card supports raid 0 and 1 and JOB, but I will concede no raid 1, as I could never get it to work, so in the end you are right.
923996
No. This card has no RAID functionality. You need to find a card that offers RAID 1, which is drive mirroring, to do what you're looking to do.
923997
RAID 1 will mirror your disks for backup/redundancy that you want. There are different levels of RAID. RAID 0 WONT do what you want. So make sure you setup RAID 1 for this.
923998
Yes, but very hard to setup and the support / support page is useless......good luckI would spend more and purchase from a different company, I will never buy from this company again.Even if you have raid, you should still have at least 1 (2 or more is better) disk outside your box that has a backup running to it every day.

This is not a RAID controller. This is a SAS expander. It works in conjunction with a separate SAS controller card, like the IBM M1015.

No, RAIDS do not work this way, you cannot change between types on the fly. however, XRAID, which this model offers would give you redundancy and is expandable (can't remember if this can be done with 2 drives though).

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.

Although I haven't done it with this particular array (I'm using it in RAID5), by the regular principals, it doesn't look good. If they were individual drives, absolutely not. If they are removed from another JBOD, they would have to be in the same order, and would depend on having the same firmware. Basically... I wouldn't try it with any array. What you're looking for is probably something with a port multiplier in it so that each drive is handled individually by your OS. Then you'd need a port-multiplier compatible eSATA card (or usb if you like slow drives).

Why would you need to do that? This is an array you would pop the bad drive out slap a new one in and it would rebuild the data on its own. The default is raid 1 but you can customize to your preference.

No, this is a clone tool for 2 drives not in use or if you have an internal drive that is not primary. If you have 2 drives and don't want to run software to copy them this is the way to do it. Keep in mind its not instant. I copied a 3tb drive and it took 3.5 hours. It can also be used to create a RAID but I wouldn't use it in production.

Yes just make sure whatever raid utility you choose can utilize 4tb partitions otherwise you'll have to have 16 2tb partitions. Also make sure not to use anything such as Western Digital Green drives that have auto off or time out features as it will break the array every time one of the drives powers down. I use Seagate Barracuda drives in mine.

Hi, yes indeed, as well as being a raid 0, 1, 5 unit this product is also a very competent JBOD (just a bunch of discs) that interfaces with your via a decent USB 3.0 port. It very (too) easily switches between those storage configurations; just don't make the mistake of switching before you've backed up your data!!

Yes. RAID 0 will give you 4 GB of NAS storage with no protection. RAID 1 is with mirrored drives where if one drive fails you still have your data on the other drive. Only 2 GB of storage with RAID 1

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.

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.

Quick note. I bought one new from amazon and it did not come preconfigured RAID 5. I had to select it from the interface. I'm glad I checked before migrating my files to the drive. Other than that, it's been great.

Minimum RAID 5 configuration is 3 equal disks, I think you can add or replace one and regenerate RAID configuration again, but don't risk your data, since my data is more costly that the 4th disk value, I would prefer to buy max configuration to avoid surprises

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.
2098066
Only if you fully backup the drive as it will have to be reformatted for RAID. You should backup anyway as you have only one drive and stand to lose all of your data.

when the drives are hooked to it, boot the system there is a key combination to enter the configuration screen, it will show your drives and you tell it what type of RAID you want to setup and when you want to do the data transfer, it is backwards compatible with SATA III, some of the new drives come with a jumper to make them work with older computers also, at a slower transfer rate
