Intel 520 120GB - Is it bad or harmful to "secure erase (internal command)" often the drive?

post #1 of 6
Thread Starter 
Hello, my question is basically the same as what the title says.

Thanks to anybody who has to contribute any insights and important information on secure erasing SSD-drives!

No, it is not harmful or bad to secure erase an SSD.

The only thing that could be called slightly harmful is that a secure erase is the same as using one full program/erase cycle on all the NAND in the SSD. That is a extremely tiny loss of the NAND's life span, and not at all worth worrying about. The concern over wearing out the NAND in SSDs has been found to be very exaggerated.

Normally it is unnecessary to secure erase a SSD often or at all, a simple Windows quick format will be enough to start over again.

Any reason you need to secure erase your SSDs a lot?

A secure erase is not needed most of the time.

I asked because of re-installing windows, I mean I might do this a couple of times so I guess it is not a big deal. One reason to ask this is because Ive seen information that secure-erase is risky because an ssd can turn into a brick during the process.

Secure erase = one full P/E cycle of every nand on the SSD.

Running quick format on windows 7 and upwards = running a full TRIM. So only the nand's that have data on them would be "wiped"

Only secure erase if you're doing a reformat after using the drive for awhile. TRIM / quick erase is just fine if you're reformatting for testing and ETC.

No need to secure erase every reformat, unless you are reformatting every 1yr or so.

That can happen the ssd can not complete the secure erase and bricks , but it is not very often this happends i think.
Had this one time with a XM-25 and never made a secure erase again , If there is no need to secure erase than do not do it , the secure erase is to erase al data from ssd and makes it a fresh new one . To make a fresh new ssd a fast format with w7/8 wil do the job withouth secure erase:)

This is a kind of secure erase on soft and hardware level:rolleyes:
