What If My PC Lost Power With A SSD In It?

[Carskaterboyz]

I Was Thinking About Getting A SSD But i loose Power Alot Due To My Puppy And A Unreliable Outlet ( Things Literally Just Fall Out Like Wtf Lol? ) Will It Never Work Again And Be Corrupted?

It would as the same as a regular Hard Drive. Most likely when you turn it on it just ask if you want to start up in safe mode, system recovery, or normally.

The SSD would be fine without power. You may want to look into a UPS to allow you to safely power it down. It would prevent loss of unsaved data.

Thank You So Much Ive Been Debating On Wether To Buy One Or Not For A While I Was Planning On Just Using It for Battlefield 4 To Load Maps Same With Titan Fall And Battlefield 3 Or Should I Only Use It As A Boot Drive?

If you have enough space on the drive, I would use it for the boot drive and any programs that you use a lot.

Power loss events are more dangerous on a SSD. On a HDD, the data is stored in a static location addressed as a sector. On a SSD, the data is stored in a static cell, but the mapping of that cell to a "sector" of the drive is via a virtual table. It's done this way to allow the drive to move data around for its wear leveling algorithm, without making it look like the data has been moved around to the computer.

If a power interruption causes an erroneous write to that virtual table, not only can it corrupt data, it can degrade the SSD's ability to function, or even kill it entirely. Some SSDs have a small capacitor to keep the drive powered to finish any writes that are queued up during a power loss. I know the Plextor and some of the Sandisk and Intel SSDs have this. Unfortunately, I don't know which SSDs don't have this. So hooking the computer up to a UPS is probably a good idea (it's a good idea anyway).

Oh Do I Even Have To Put A SSD Inside My PC? I Saw With The Kingston They Have An External USB Caseing Would That Affect Speed?

Unless its in a USB 3.0 Case plugged into a USB 3.0 Slot on the PC then yes you will see a very considerable slow down. USB 2.0 is 480 Mbps. USB 3.0 is 5000 Mbps and a SSD that uses SATA III Runs at 6000 Mbps. So you are cutting the speed down to 1/12 the speed if you are only using a USB 2.0 case/Port.
