Subject: blkdiscard vs hdparm for erasing a SSD?
Date: Wed, 15 Oct 2014 15:12:42 +0200	[thread overview]
Message-ID: <2523736.cvg5kvG8qa@al> (raw)

Hi,

Recent versions of util-linux have a blkdiscard program. How does this compare
to the --security-erase option of hdparm? The goal is to erase the contents of
an previously used SSD to improve performance.

Is the command `blkdiscard -s /dev/sdd` equivalent to the instructions listed on
https://ata.wiki.kernel.org/index.php/ATA_Secure_Erase?
-- 
Kind regards,
Peter
