  • Even a software raid should be telling you which drive is malfunctioning — at least Linux will flood error log with messages of failed drive.

  • If the data matters, make sure it's backed up, and that your backups are restore-tested. Show 1 more comment.

  • Desire to —grow to a third device. Also as noted, the 6 gigabit-per-second transfer rate specified for Sata 3 is only what the controller is capable of.

  • It's not the most convenient but if you are looking at cost it's the most cost effective approach as i believe cloud would not be much of an option because of the internet connectivity. We have done this without any loss of data.

Possibly the hot spare failed or this is a second production drive failure and no secondary hot spare If you want very good, redundant raid, use software raid in linux. Your results may vary.

The other option is to use replication which would require 2 arrays to fail at the same time No wonder you have RAID 5. How much of a problem that turns out to be will depend on the site and performance demands of the application being supported. Please see my comment above.

However, you'll also find the failure rate of more expensive disks e. Again, RAID is not a backup alternative it's purely about adding "a buffer zone" during which a disk can be replaced in order to keep available data Having your drives in raid5 i had 4 80gb hds in raid5 for total of gb drive space is good if you want to have a balance between a raid0 and raid1.

I will be using 8x8tb sas hdd. This ends up without a parody Drive involved which means a failure of one of any of the discs would result in the loss of all data in the raid array. It was cheaper to create a large RAID array inexpensive of disks than it was to purchase a single drive with the same capacity. Sorry I am a bit confused.

The tech who set it up could not see how a RAID 5 could slow it down, I just wanted to eliminate redundancy altogether except for my manual but lose weight backups at night and lunch. I think you've confirmed that RAID performance and function will not collapse if we need to buy the closest possible drives in a few years to replace failures. Your space will be limited to your smallest drive in the RAID 1, no matter how many drives you have.

  • RAID 6 needs 5 or more drives to be worth it. That means a RAID 5 array can withstand a single drive failure without losing data or access to data.

  • RAID6 would give you 3 disks worth of space, and can tolerate two failures as well any two. Does the parity drive need to be identical?

Please help. Featured in a NEC server rack mount. I've used it several times on servers. That is why you use Time Machine for the data residing on the internal drive but of course the same also applies to the data that will be stored on those mirrored drives. It worked for documents, but not for large or small amounts of data needed to be drawn. Thank you so much. SSDs will get you much closer than any hard drive, but no storage media will actually ever reach the maximum transfer rate of the controller.

GORT wrote: First and foremost, order the replacement drive. It only takes a minute to sign up. Or, if it helps to visualize RAID another way, imagine a basic RAID-0 array, except every individual hard drive in the array is actually two twinned drives. Data is stripped across all of your drives.

Hi, there is a mistake. Both read and write. I need to deal with very large data set with typical file size of gb, hundreds of them, in a workstation. This is true of all RAID setups. RAID 1 — Mirroring.

But maybe i'm wrong; somebody correct me on this. And rzid during the time i have the NAS; my logic was since my backups and data are stored in the 4 HDD's; better make it as resilient as possible whilst being almost plug-n-play friendly for anybody else to troubleshoot it if ever i'm not around. It would take a catastrophic multi-system failure like in-the-building lighting or EMPtotal theft of user systems and servers, or a malicious user intentionally deleting files to even require need for the backup data. If another drive dies during that time, you still lose all of your data. The result is also in 1s and zeros.

You have backups, right? See btrfs and zfs. Now we can perform an XOR calculation on the three blocks. Each system utility reads from and writes to files on drive lose weight RAID level being tested. Depends which two drives go Reed-Solomon error correction codes also see use to correct any sort of data corruption that can naturally occur in any sort of high-bandwidth data transmission, from HD video broadcasts to signals sent to and from space probes. RAID-1 tends to be used by home users for simple onsite data backup.

RAID is no substitute for back-ups!

It is the end result of calculation of data written on a disk as in 1s and zeros. The move to SSD is motivated purely by performance, as I assume is the case for most users, with power savings being a secondary benefit. Thanks for your help, Colin.

If you can leave an empty slot between adjacent drives, that will also allow them to run a bit cooler. This will also be slightly cheaper as an 8TB drive costs drive lose than 2 4TB drives. Also the 6Gb per second Sata 3 transfer rate only applies to sequential reads, which are faster than random reads, particularly on rotating media. Basically just looking for redundancy and not to worry about losing my files, pictures, movies. If it is only, or mainly, for backup, you don't have to worry as much. I'd do exactly this.

Raid 5 only requires a minimum of 3 disks. Some might think there is lose weight and only one way to create a solid backup strategy. However, if even those drives are still the likely first-point-of-failure by a statistically significant margin, then I'd rather stick with RAID and avoid that likely source of downtime. From everything I am seeing on comparisons between both, if you only have 4 disks, the fault tolerance and performance are the same. A RAID 6 system even survives 2 disks dying simultaneously.

The only other approach that I think may make sense for us is to actually go with individual higher quality drives, if the failure rate is really as close to zero as I've read in some reports Anandtech comes to mind. The parity is used for recovering data in case of drive failure.

RAID 6 is a good all-round system that combines efficient storage with excellent security and decent performance. Also, if it's backup, performance isn't really an issue.

Using the parity data, the computer can recalculate the data of one of the other data blocks, should those data no longer be available. How would RAID1 be cheaper? Other than that, it has the best performance and redundancy of all RAID levels. I don't see RAID5 as any more complex from a support perspective than RAID1, other than that I suppose statistically there will be more replacements in a RAID5 configuration, simply due to the higher number of drives, but the "lunch hour" replacement is a non-issue for us, so that's fine.

One of them is stored at my parents house and during each visit I swap them out so Losw always have an off-site backup.
