Raising the Capacity Bar with New Technologies
- The first HDD in the industry to harness Energy-Assisted Magnetic Recording (EAMR) technology improves writability and therefore increases areal density.
- The industry’s first Triple Stage Actuator (TSA) enhances head-positioning accuracy, delivering better performance and increased areal density.

Trusted Reliability and Quality for Data at Scale
- Projected values. Final MTBF and AFR specifications will be based on a sample population and are estimated by statistical measurements and acceleration algorithms under typical operating conditions, typical workload and 40°C device-reported temperature. Derating of MTBF and AFR will occur above these parameters, up to 550TB/year and 60°C (device reported temperature). MTBF and AFR ratings do not predict an individual drive’s reliability and do not constitute a warranty.

Ordered this drive to place in a OWC ministack case. The first drive that was received was DOA. Would not be recognized by any computer I tried to install/format it with, even using an external drive holder. I contacted OWC to initiate a return, that's where the fun started. The online system wouldn't allow me to create a RMA. I had to go to the chat section of the website to start an RMA. That process was going good, until for some reason I got disconnected from the chat server. Re-initiated a second chat, that went better and got the RMA. Once i had the label I sent the drive back, then every couple of days I would get a message from OWC that they hadn't heard from me about my case and if I didn't respond the case would close. I sent a reply email, indicating I had shipped the defective unit back and advised OWC that the unit was scheduled to be delivered the next day. Great so far, a few days later another message from OWC, they hadn't heard from me and if I didn't respond my case would be closed, WTF? Then a couple of days after that I get a notice of a shipment from OWC, guess what? the replacement drive for the defective unit. Great! The drive arrives I install/format it, the world is good again. A few days later, I get an email from OWC, they hadn't heard from me and that my case would be closed, WTF part 2?
