When conducting large-scale refreshes of our IT equipment, I'm curious about the best practices for certified destruction of HDDs and SSDs. I've noticed that there are usually three main approaches: using NIST 800-88 overwriting for HDDs, crypto-erasing SSDs (if supported), and physical destruction when crypto-erasure isn't an option, ensuring the pieces are of a controlled particle size. It's crucial for us to maintain serial-to-device mapping before and after the process, along with a verifiable chain of custody and reports that auditors can easily access without additional explanation.
For larger batches, we've utilized services like E-Waste Squad, which provides a uniformed team and tamper seals during pickup, along with precise per-serial inventory and destruction certificates issued within 24 hours. Their processes are compliant with R2v3, ISO 14001, and NAID AAA, which really eases our audit process. What specific requirements do you include in your Statements of Work (SOW) when outsourcing IT asset disposal? Do you ask for features like on-site witness, photo/video of shredding, sub-24 hour SLA for certificates, or even on-site destruction for certain types of media?

Sometimes, the easiest way to handle those old drives is just to take a shotgun to them! It's definitely effective if you don’t mind the mess.
It sounds like you're already hitting most of the key points that auditors care about. In industries like finance and healthcare, the main things we focus on are:
- A full serial-level chain of custody from the point of pickup through to destruction.
- Fast certificate turnaround — we aim for under 48 hours, and definitely under 24 hours for any sensitive data.
- Clear proof for each method: logs for overwriting HDDs, confirmations for crypto-erasing SSDs, and verification of particle size for physical destruction.
- Having NAID AAA and R2/ISO certification makes a big difference during audits.
For more sensitive equipment, we often require on-site destruction or at the very least, live video showing the serial number as they're being destroyed. It’s a slower process, but it significantly reduces the headache during audits later on. One thing that often gets overlooked in SOWs is how to handle drives that can’t be wiped, are unreadable, or have damaged serial numbers. Defining the exception process upfront is vital to keep things smooth when managing large volumes of devices.
Just curious, are you genuinely concerned about the particle size? Like, do you think someone could take a chunk of shredded flash memory and figure out how to reconstruct encrypted info from it?
