If I purchase a 4X3TB set up, can I replace one drive at a time to make it into a 4X4TB?

Yes, according to the manufacturer you can replace any drive at any time. Just be cautious if you use raid, you will need to be able to "split" you capacity in half so it is best to have a balanced distribution of drive capacity.

William,Yes you can, the diskless EX4 through the 16 TB EX 4 cases/software are all the same and will accept the WD 4TB drives

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.

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

changing the drive is easy, any SSD SATA would do. I would go about 250g or bigger if you can afford it. Don't forget to clone from the original to get all the proper drivers .

To the best of my knowledge: No!. You'd have to verify with the company, however. I've only used drives up to 2TB (mostly due to OS compatibility).

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).

Two 4TB drives. You can configure it to mirror those two 4TB, split it so parts if each file could end up on both drives (makes it very fast, but vunerable to corruption if either one fails), or separately to use them as two unique 4 TB drives for a total of 8TB.

Yes. Drives are hot-swappable, so you can replace them (one at a time) without even turning off the unit or losing access to your data. Time for new drives to stripe depends on size and amount of data on drive.

I have a 3tb drive in mine and it works fine I don't see any reason why it won't work with a 4 Tb drive

Yes you can! Simply leave the unit in JBOD mode and install any drives to access them. The drives will not be reformatted or overwritten. Please let us know if you have further questions. Oyen Digital Support

ABSOLUTELY. I have been using a pair of 3TB, a pair of 4T and a pair of 1 TB seagates for some time with no problems. I do not use any of their special back-up software. (KIK, Ph.D.)

No. The days of internal expansion are over. Suggest you take a look at the 2013 model, you can 4 Drives.

Practically you will need to put your drives into another DiskStation - I've done this and the data was migrated with no problems and no action needed from me. However, mind that you can't put 7 discs into a 4 bay box - but if you have only 4 drives in your 8-bay box, you can put them in a 4-bay box and they will show. They also must be put in the new box in the same order as they were in the old box.

The Perc6I will not support larger than a 2TB HDD. In order to use a 4TB you would need to upgrade to a H700 controller.

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.

You can replace the drive with any size SATA or SAS drive, however if you are using RAID you should have all drives in the astray match capacity. SAS and SATA cannot exist in the same array but can be set up in dire separate arrays on the same controller.

Yes, this can be done with Synology Hybrid RAID (SHR). And yes, the process is not difficult, i.e. it is "smooth" (if you meant something else by smooth, please let me know). But upgrading the drives on this unit is one of the benefits of it. If you use traditional RAID options, then no you will not be able to upgrade one drive at a time to increase capacity. From my discussions with Synology, 12 bay units are generally recommended with traditional RAID, but they did indicate that many people use SHR with no problems.Personally, I would try to minimize use of the unit during the upgrade since it may help speed up the expansion.

With the Synology RAID option you can start with the 3TB drives and add larger ones later. You just can't anything of smaller size than the drives used to create the array.
