Can an SSD be securely deleted of data?

Can an SSD be securely deleted of data? I read somewhere that there is no way to be sure one has scrubbed it clean as it's digital unlike the old HDDs.

You can issue a Clean All command. That will write all zeros on the SSD. It is not really recommended because your future write commands will be slowed dowm, but it would make is difficult to recover the data - except with forensic tools.

And this is one reason why I refuse to buy an SSD. At least with a spinner I can erase everything and know it's gone.

I have wrote Zeros using Partition Wizard Mini Tool to 3 ssd and have not had a problems with any of them.
After that I check them with Intel ssd ToolBox and they are at 100%.
I don't baby ssd's. I just use them.
I use Intel ssd's that have a 5 year warranty. If they die they die.

Jack is right. There is too much fuzz being made about SSDs. Just use them like any old disk and you will be OK.

Hi,
The 2 ssd utilities I've seen a Samsung and a Crucial both have secure erase.

Anyone interested in this subject (especially the paranoid) needs to know about PrivaZer, which not only will clean your drives (even RAM!) of personal data (in all sorts of hidden places I never knew about before) but also has multiple options for how erasures are done, from simple "1-pass zeros" to OMG "6 pass USA Army 380-19" (dunno what it is, sounds good doesn't it).

It is donation-ware i.e. can be free if you're cheap (I am not!).

That is more fallacy than fact. HDDs and SSDs are completely different beasts: you can't treat one the way you do the other. With both SSDs and HDDs, you can't just delete data and expect it to be unrecoverable. With HDDs, you can overwrite data with 1s and 0s to be sure it is unrecoverable without harming the HDD. You can do the same with SSDs but that would use up some the finite amount of writes available (which actually is less of a problem than what most people believe). However, there are ways to do a secure erase on SSDs that won't unnecessarily reduce the write life of an SSD, the easiest being to use the function provided in the disk utilities provided with most SSDs.

Who cares, what do you keep Government secrets on your drive ? That is the lamest excuse ever not to get an ssd.

And no, you can`t erase everything on a spinner, whoever told you that ?

The only way to get rid of data off a spinner is to drill 1/2" holes threw in then throw it in 500 feet of Ocean

Intel's ssd Tool Box also has a Secure Erase. I will use it next time to see if things go quicker.

Take a think on ram. How many times is it wrote to and then erased. Ram of course is solid state just like a ssd.
Does one remove the ram to save it for a later date? Heck no, use it if you got it. Find something else to worry about like global warming, bobby socks, or maybe Pluto.

I have no secrets on my computers. Well if I do they are also secret to me.
I did the erase because I used the ssd's for testing Linux and when I did formats their was always a little bit of Linux still on the drive. I want the ssd's to be completely clean to make thing work better for my next little test journey. I did notice when I did my last Clone on a wiper ssd things went faster with no interruption.

Just my thoughts.
