Solve : ssd and data corruption? |
|
Answer» Hello, and thanks for helping. My question in a nutshell is, is it more essential to use a ups with a ssd than a conventional hard drive? In a nutshell, my answer is "No, it is not essential to get a UPS just because you have an SSD, as long as you get one which has power loss protection, and many do." In addition I would say that if your local power supply is subject to surges and outages you should have a UPS whichever type of disk you use". I have a Samsung Evo 840 SSD as my main system disk, and I take regular image backups to external drives, (one NAS, one USB) and if the SSD fails or suffers corruption, I can restore my essential data and the system, either onto the existing SSD or a new one. I did this when I had a spinning drive. Almost all of these myths about SSDs are either total nonsense or only apply to very early SSDs. With a decent modern drive you won't have any of these issues.Thanks guys, I too am getting a Samsung evo (500GB) and I wasnt sure what was fact and fiction about a ups. I get no more power outages than anywhere else i guess, and yes im paranoid about backups, havent learnt the hard way years ago. So much so that i have 2 4 bay qnaps, and one is purely for backup of the other, no raid for me. Also have backups on usb hard drives off site. Looking forward to ssd technology. Thankslicoriceallsorts, Most likely you know more that most of the forums regulars. The myths about SSD are abundant. But the factual reports show that SSD is better in every way. But you already know that. Here is just one report of interest. It comes from Toshiba. Ten Myths about SSD VS HDD. (PDF) The main recons to still use HDD are that it supports an ESTABLISHED industry and its demise would bring economic hardship. Quote Almost all of these myths about SSDs are either total nonsense or only apply to very early SSDs. With a decent modern drive you won't have any of these issues. I also agree with Camerongray on this subject... The newer SSD's actually self power themselves for a very short period after power disruption to COMPLETE the write process and not have a partial write from that of which data is in the cache of the drive to be written. If the drive is simply being read while a power outage, then no harm is done. However when data is being written to any drive that is when its critical that the data be written and completed of its write process to avoid corruption. So most SSDs these days have a small capacitor bank on them to keep the drive powered for a very short period of time that allows for the drive to detect the loss of power and then react to close the write process vs partial to avoid drive corruption. Quote Power-Loss Protection: In the rare event that power fails while the drive is operating, power-loss protection helps ensure that data isn’t corrupted. To supplement our power-sensing firmware protection, our SSD engineers designed physical power reserves (capacitors) that are specifically tailored to our NAND requirements and deliver ENOUGH power to ensure data remains intact. Also... I am a firm believer in that computers should have at minimum a surge protector to protect from spikes, but if its a desktop computer I always suggest a UPS with the computer plugged into the battery backup side to avoid problems. If its a laptop a UPS isnt really needed unless you have external drives that are powered externally vs off of the laptops USB port. If using a laptop that is plugged into the wall for power and you have a 30 minute power outage you can pretty much keep going on the laptop as long as its offline interaction since most people also dont have battery backups ( UPS's ) on their network equipment. I myself have 1 UPS tucked under entertainment system to keep the TV, Broadband Modem, Wireless Router, and Vonage Phone System operational during a power outage, as well as I have a UPS at each of the 3 desktop systems in my home and a spare that is powered as an extra battery to have a portable 120VAC source for an extended outage to unplug and plug a lamp into etc if the outage is at night etc. (* I removed the piezo speaker from it so it doesnt beep and drive you nuts...LOL )Almost all of these myths about SSDs are either total nonsense or only apply to very early SSDs. With a decent modern drive you won't have any of these issues. Don't use affiliate links for your Sig...i removed it.

That's a good idea about removing the piezo speaker; will have to LOOK into it. I have half a dozen UPS's in the house since I live in the lightning capital of the world. |
