SSD Raid0 error

[jaxG]

My wife used the laptop without power source and laptop turned off. Now when I boot it I receive the an error message regarding my ssd.
Is there any option to fix the problem without deleting the partition and lose all data? And without installing windows is.
First I tried to run windows from usb but I cannot see the SSDs. Next step was to run Ubuntu OS from an usb disk check the health of ssds and one shows an error. picture 2

Check the SSD SATA and power connection... retry to replug. Other than that, there's nothing you can do.

Unfortunately, there is no way to recover data from RAID0 array. It's unreliable technology that shouldn't be used in the modern era.

For fast storage use NVMe / M.2 / High-end SATA3 SSD.

As you should know with RAID 0 it has no redundancy. So if there is a drive failure its gone. Always back up anything important

I hope you had a backup, because without sending both drives out to data recovery and spending huge amounts of money, that data is gone.

i will do it....need only some precision torx screwdriver....thanks

Testdisk can recover bad raid0 array partitions if one drive you had fails. Having power shut off is the best chance at recovering those partitions. I think you can make a bootable drive with testdisk. If not stick the two ssds into a desktop PC to run them through testdisk. Recover the bad partition with files, restore the previous partition aka raid 0 array, and reboot. it should be fine.
Same thing happened to a 1.5Tb 3 disk(500gbx3) hard disk raid 0 array and one went bad. Ran testdisk and solved everything.
you need to be a little tech savvy to understand how to use it.

I can't imagine listening to the above posters. they are sucking the life out of you. Testdisk can recover bad raid0 arrays if one had fails.

Thanks....I will also try your method

If there was one piece of software worth investing in, it would be the aomeia backupper. It can shrink partitions down to the necessary file size and restore effortlessly from external device. I shrunk my 512gb hard drive with 40gb of data into a 22gb file size.
I also transferred the windows partition and personal files from the QLC Intel 660 512gb nvme to a TLC 2tb Inland premium nvme to use instead as my primary drive. stuck those backups onto a 128gb sd card and keep extra on my external ssd, and harddrives.
Also testdisk is a lifesaver. If you can get testdisk to run in ubuntu that would be easiest. If you cant i would make a bootable USB drive and place testdisk on that drive and then run that program off of the bootable media to recover the data. The only other method is running testdisk on a desktop PC where a hardware raid 0 partition can be recognized. you would have to physically open up the desktop and connect them(you ssds) to the motherboard for it to work without any hiccups.

Once ya get it fixed .... Here's a post that is well over a dozen years old, I doubt half the sites exist by now ... nothing has changed.

Standard RAID levels - Wikipedia

en.wikipedia.org

RAID 0 is useful for setups such as large read-only NFS servers where mounting many disks is time-consuming or impossible and redundancy is irrelevant.

RAID 0 is also used in some gaming systems where performance is desired and data integrity is not very important. However, real-world tests with games have shown that RAID-0 performance gains are minimal, although some desktop applications will benefit.[1][2]

Western Digital's Raptors in RAID-0: Are two drives better than one?

www.anandtech.com

"We were hoping to see some sort of performance increase in the game loading tests, but the RAID array didn't give us that. While the scores put the RAID-0 array slightly slower than the single drive Raptor II, you should also remember that these scores are timed by hand and thus, we're dealing within normal variations in the "benchmark".

Our Unreal Tournament 2004 test uses the full version of the game and leaves all settings on defaults. After launching the game, we select Instant Action from the menu, choose Assault mode and select the Robot Factory level. The stop watch timer is started right after the Play button is clicked, and stopped when the loading screen disappears. The test is repeated three times with the final score reported being an average of the three. In order to avoid the effects of caching, we reboot between runs. All times are reported in seconds; lower scores, obviously, being better. In Unreal Tournament, we're left with exactly no performance improvement, thanks to RAID-0

If you haven't gotten the hint by now, we'll spell it out for you: there is no place, and no need for a RAID-0 array on a desktop computer. The real world performance increases are negligible at best and the reduction in reliability, thanks to a halving of the mean time between failure, makes RAID-0 far from worth it on the desktop.

Bottom line: RAID-0 arrays will win you just about any benchmark, but they'll deliver virtually nothing more than that for real world desktop performance. That's just the cold hard truth."

".....we did not see an increase in FPS through its use. Load times for levels and games was significantly reduced utilizing the Raid controller and array. As we stated we do not expect that the majority of gamers are willing to purchase greater than 4 drives and a controller for this kind of setup. While onboard Raid is an option available to many users you should be aware that using onboard Raid will mean the consumption of CPU time for this task and thus a reduction in performance that may actually lead to worse FPS. An add-on controller will always be the best option until they integrate discreet Raid controllers with their own memory into consumer level motherboards."

RAID-0 proved ineffective at boosting desktop application/game performance

Clicky, check out the bar graph towards the bottom of Eugene's post. SR will be posting a pretty comprehensive article on RAID, hopefully soon. The graph is a selection from the results obtained for that forthcoming article. Even running _four_ WD740GDs in RAID-0 is not enough to match the...

"The real-world performance benefits possible in a single-user PC situation is not a given for most people, because the benefits rely on multiple independent, simultaneous requests. One person running most desktop applications may not see a big payback in performance because they are not written to do asynchronous I/O to disks. Understanding this can help avoid disappointment."

"What about performance? This, we suspect, is the primary reason why so many users doggedly pursue the RAID 0 "holy grail." This inevitably leads to dissapointment by those that notice little or no performance gain.....As stated above, first person shooters rarely benefit from RAID 0.__ Frame rates will almost certainly not improve, as they are determined by your video card and processor above all else. In fact, theoretically your FPS frame rate may decrease, since many low-cost RAID controllers (anything made by Highpoint at the tiem of this writing, and most cards from Promise) implement RAID in software, so the process of splitting and combining data across your drives is done by your CPU, which could better be utilized by your game. That said, the CPU overhead of RAID0 is minimal on high-performance processors."

Even the HD manufacturers limit RAID's advantages to very specific applications and non of them involves gaming:

Again, nothing's changed... we set up a test bed about every 3 years. last one had (2) SSDs in RAID 0 ... (2) SSHDs in RAID 1. After three months of unsatisfactory performance ....

a) Called Samsing regard the Pro series SSds ... "We do not recommend nor support RAID on any of our SSDs". Broke the array and performance improved.
b) On the SSHDs, every now and then one of the disks would disappear.... broke the array and mirrored them with a fotware mirroring utility (FBackuo) that runs twice a day.

HELLO, What a load of gibberish. Once storage exceeds 80% capacity, performance lowers drastically. Raid 0 effectively prolongs the performance by spreading the capacity across an array. Useful if you have tons of storage taken up , and a high performance drive, ssd or nvme that you want to maintain without losing performance. Performance longevity isnt possible without raid in place. That would be rational justification for raid 0, for my system with the 2x2tb nvme drives, since the game drive is 90% full and the other is 50% full for one 4tb drive. Any Performance gain with raid 0 is added benefit.
