SSD degrade?

post #1 of 20
Thread Starter 
I am looking into SSDs. I want to find some cheap new/used drives and I keep reading about degradation and trim, but what does this mean? Is it as it sounds The SSD physically comes worn out and will die? Or is kind of like when a HDD gets fragmented and has to be defragged?

actually you want to make sure the SSD has NOT been defraged, as its bad for the drive.

Though, i'm not sure it matters after the drive has been formatted

I know its not suppose to be defragged. But I was trying to using it as a comparison to the performance drop in a HDD that is fragmented and can be fixed buy cleaning up the garbage and they drive is good to go.

Never defrag an ssd. Trim will take care of the drive pretty well...call it a virtual defragger that eliminates broken bits of data. Eventually the drive will be useless, but it'll take some time.

Solid state memory such as those inside of a flash drive, your phones, and a SSD have a limited number of read/write cycles IIRC. Meaning that with every operation you are technically taking some of it's life away. Which is why I only use mine for Windows and a few programs. I don't copy things to and from my desktop all that much and use my storage drive for almost everything and just make shortcuts if needed.

Every SSD will have this and I don't know if there is anything you can do about it, such as defragging a HDD.

Ok then who do you get trim? is it a bios thing, in the firmware of the drive or is it an OS thing?

How long would it take for the drive to die? And how much read/writing would it require? And so what does trim have to do with this?

IIRC TRIM is a command set forth by the computer itself telling the SSD to delete certain bits of information which it does not need and which could cause slow downs down the road.

Think of it like defrag for SSD's. Only it's not defragging. Lol.

It's garbage collection basically. Every time you delete something on an SSD part of the file is still left there, kind of like a reference point. This is something that windows can do by itself on an HDD, but not a SSD.

I'm really botching this up. Someone help me if I'm wrong.

In the meantime read the TRIM Wiki.

Check out this Anandtech Article too.

Just to put things into perspective, I'm running a 3 year old SSD and it's STILL completely destroying by like 800% my Raid0 setup with regards to Windows performance. It doesn't have TRIM either.

Will give it a look through.

That sort of answers the life expectancy of a SSD. But when they say it degrades over time does it mean in 5 years I be complaining is slow or in 5 months one day when I just on the computer it will take 5 minutes instead of 5 seconds? Exaggerating a bit on some things for dramatic effect.

It'll take years. Trim is set in bios...run the ssd in ahci mode. Don't benchmark it constantly, tis all.
