Two questions about Raid 0:
My situation:
My motherboard with RAID controller got sent in for an RMA (3 weeks turnaround). Asus sent me back a different motherboard that had way worse problems than my previous motherboard. So I have to send it in again to get repaired or replaced. So I am 3 out of 6 weeks through not having access to my Raid 0 2x1TB SSD Boot drive (Windows 10) that was dependent upon that motherboard and RAID controller. I'm getting desperate because my password database is on that raid drive as well as hundreds of GB of Steam games that I can't download again yet (data caps).
I have some computer hardware laying around, such as 'mediasonic HUR2-SU3 Sata-to-USB3 docking station' which I read thoughtlessly that it could recreate a RAID. Obviously it did not do so. It supposedly has something to do with Linux RAIDs, but I don't think it applies to me.
But I was wondering if in the modern world, there is any way to take my two 1 TB SSDs (Sata 3) (raid 0 from hardware controller) and have them both connected to one of my 2 laptops (Asus FX53VE or MacBook Pro E-2011) and somehow scrape coherent folders and data off of them. I don't want it destroyed or deleted, only accessed. With enough time and effort, there must be some way to do it.
FYI: I only have 2 laptops at the moment**, so no RAID cards via PCIe (I do have one). This is because I just sent my motherboard back in to Asus for ANOTHER RMA.
I have a 4 disk QNAP NAS with 4 8TB WD RED NAS disks in it, in ** 0. What is the life expectancy of my data in RAID 0, assuming I check the SMART data and am on the lookout for signs of failure? The HDD is WD80EFZX.
Thanks a lot for reading! I have some more questions about Qubes OS and Linux installs, but I have more research to do before I ask them, and I know there is a different community for that.
Edit: I'm getting some nice new information from a different thread: Mount existing 2-HDD RAID 0 on a new machine that I could not find before.
“What is the life expectancy of my data in raid 0“ - What exactly do you mean by this? RAID 0 provides no redundancy, if any drive in the RAID fails, your entire RAID fails. – Ramhound – 2018-06-19T00:24:57.837
There has to be some statistical answer about the life expectancy of individual raid disks. It might be true that 4 disks in raid 0 are twice as likely to fail as 2 disks in raid 0, and that's a start. But I would imagine with the expertise around here that somebody could give me a nice answer in "hours" format. – Mindus Amitiel Debsin – 2018-06-19T00:29:41.603
The expected lifespan of any HDD is around the same amount of time the warranty. We cannot predict the life expectancy of a drive. – Ramhound – 2018-06-19T00:41:25.877
“There has to be some statistical answer about the life expectancy of individual raid disks.” It’s no different than normal hard drive live expectancy. – JakeGould – 2018-06-19T01:20:54.010
The zero in teh name indicates how much data you are likely to get back, esp if the actual disk layout isn't exactly standard perfect and info was stored on the old controller. Use Linux, and use software RAID1 or 5. I've pulled a software RAID set out of a dead machine, put them in a new totally different hardware machine, install OS on non-RAID-ed drive, and gotten my storage back online in 30 minutes. – ivanivan – 2018-06-19T03:39:28.067
@ivanivan which os is used has no bearing on the reliability or accessibility of RAID arrays. Linux is not a magical solution for everything (or anything really). And RAID5 comes with a large performance hit compared to many other RAID solutions. This is especially true with software raid or hybrid raid controllers (like most motherboard integrated controllers) where parity calculations have to be offloaded to the CPU. RAID5's only real advantage is redundancy affordability per GB. And even then RAID6 is a better choice there because it can suffer 2 drive failures before data loss. – Cliff Armstrong – 2018-06-19T18:57:18.980
@CliffArmstrong - meant to convey that software raid frees you from the controller, and software raid is available in linux. – ivanivan – 2018-06-19T20:00:17.153
Fair enough, but Windows Vista and newer has software RAID as well (as do most other *nixes and, I believe, newer editions of Mac OS X). And it's equally transferable between Windows Vista+ installations. Windows <-> Linux? Probably not. Linux <-> Other *nixes? Maybe. – Cliff Armstrong – 2018-06-19T20:33:20.260
