The 512 GB model uses 2 x 256GB SSD's in RAID 0. Can it run RAID 1 for redundancy rather than speed?

Yes, you can change in the BIOS. But doing so requires you to reinstall the OS. You may also run the 2 SSD as JBOD which is what I am doing with mine.

I have 5 of these drives in a Sans Digital RAID box configured as two 2TB RAID 1 drives with a hot standby replacement drive. I've been running almost two years with no problems. I chose the lower spin rate (5400RPM) to be more reliable. I use the RAID 1 drives for backup/archive of other computers.

Absolutely. there are always SOME weird motherboards and some NAS's that don't like certain HDD's, so it isn't guaranteed, but it's a real nice, solid, good working drive. Read some reviews on it. In RAID 0, by the way, you can make up for the 5400 RPM and make these things scream and still have the low heat, low power consumption.

Use the Intel Raid Controller that is on your motherboard if you are going RAID 0, that's what I would do. I am using the card for an SSD which was perfect for my computer, big jump in performance. Not sure how it would work under RAID 0, seeing how I have never used it for that. Hope this helps.

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.

Yes, but why use this old card now for RAID? The SATA supports only 150 MB/s. Most new drives will be SATA III, 6Gb/s or up to 550 GB/s. Just my $0.02 worth.

It's a single disk hard drive. You could format it to have two partitions, but that won't give you physical redundancy. If you need the redundancy of a raid system you're going to have to move up to one.

They are just drives, so they are hardware dependent, not software, and will work with any SATA 2 or 3. I use pairs of disks of this type on 4 computers in RAID 0 (hardware Raid, but software might be good too in new computes). So, I recommend RAID 0 with two of a smaller size instead of a bigger one, you will get stable >250MB/s with quick access time, and will not be jealous to an SSD, since it will be cheaper and, probably, safer in a desktop. They are rather low-power, stay cool and silent (slightly model dependent), and I did not see a defective one after a few years (mine are marked "enterprise storage", but this is same 5-year warranty) They are just drives, so they are hardware dependent, not software, and will work with any SATA 2 or 3.

Absolutely, I would always recommend RAID 1 or 10 if you can afford the extra drives. Though I've not yet done it, SSD's should be able restore a RAID array faster in the event of a failure.

the one I have has a 256 gig solid state in it. It partitions down to a little bit less than that

SHR is more flexible, if you want to upgrade to larger drives later. No downside -- you're locked into the technology once you but the DiskStation, so you may was well leverage the proprietary RAID

I'm running 4x1.5TB drives with ZFS RAID-Z and Ubuntu 12.04 LTS on a flash drive with 2x4GB 1333. It's been performing very well, no complaints! I'm just not looking forward to when I have to upgrade those drives, at least they were free.

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 am using two 1TB drives in RAID 1 mode, the manual says "2 x 2.5" SATA HDD, total capacity up to 6TB".

a Raid 5 will accomplish the same thing, while not requiring as many drives. The drives work together to increase speed, while they're also fault tolerent so 1 drive can crash without loss of information. If that's suitable, that would be the best option. You need at least 3 drives and the space will be 2/3 of the total capacity.

I believe by default they come in a RAID 1, which would give you 2TB of total storage. If you set it to RAID0, you'll get use of all 4TB (probably 3.6 or so useable) but you will not have redundancy.

Yes, This drive will run fine in a RAID 0,1,5 setups. I have tested in all three formats and currently run 1 setup in a RAID 1 and a 2 setups in RAID 5's.
