Have a need to securely erase some hard drives. Anyone recommend a tool? Saw this at CDW:

StarTech.com USB 3.0 Standalone Eraser Dock - 2.5"/3.5” SATA SSD/HDD Drives
https://www.cdw.ca/shop/products/StarTech.com-USB-3.0-Standalone-Eraser-Dock-2.5in-3.5-SATA-SSD-HDD-Drives/3796585.aspx

Anyone tried it, or something like it?

I don't know if they have changed their recommendation but the US Dept Of Defense always recommended that a drive should be erased 7 times.  Do you plan to reuse the drives?

Key question I guess is do you plan to re-use the drives again? For me, when I don't need the drives, I always go down the physical destruction route with a trusted company. I also get a 'certificate of secure destruction' so I can prove to auditors that the drives have been securely destroyed.

Ain't no recovery from this.
As mentioned most shredding companies do it with certificates.

If I don't plan to re-use the drive, I have a torch that I use for plumbing. There is no reason to pay anyone.

Some of the drives will be reused, so that's why I want to make sure the data on the drive is erased properly before reusing. And some of the drives are SSD drives, which I understand makes erasing the drive different than standard hard drives because the data management features on SSD's are more complicated because the data is distributed across the internal memory chips.

According to that site, the process is different for different manufacturers. 

Aside from that, there are a number of software companies who claim to follow the DoD standards that I mentioned before.  One of them is:

A google search for department of defense wipe ssd drives will produce many more results.

For re-use, as others have already mentioned, SSD/flash drives cannot be securely erased via the traditional methods used for spinning platter media (over write) so booting up the old DBAN CD and running the typical over routine won't work for them.   For more details, check out the NIST standard.   For SSD, the current best method if being re-used is to fully encrypt the drive using a  known secure encryption method and make sure the key is unrecoverable.  Some drives come with this capability built into the BIOS/drive setup (the ability to encrypt the drive and erase the key)

 If re-use is not a concern, physical destruction is always the most secure.

See here for detailed technical specs

The bootable disk / USB image called "dban" works pretty good to wipe a hard disk for re-use.

I bought this to use at work. It will securely erase (DoD) as well as copy, duplicate, etc. It works beautiful and I recommend getting one of you have a recurring need to mess with HD's.

I never thought about that problem for SSDs.  Wouldn't completely over-writing them wipe the data, or are there extra memory cells in the wings that don't get used until the others die?
Another reason to use BitLocker -- all you've got to do is wipe the key and the data's still there, but good luck cracking it.
