Grade Scale:
 
A+= NO BAD/Reallocated Sectors and/or 95% or higher health
 
A= up to 1 Bad/ Reallocated Sector and/or 70-94% health
 
B= up to 40 Bad/ Reallocated Sectors and/or 60-69% health
 
C= over 40 Bad/Reallocated Sectors and/or 50-59% health
 
Drive Grade will default to the lower grade if one of the requirements for that grade is met
 
**Packaging**
I use several air pillows and fill in every gap with high-quality packaging paper. All drives are double-boxed in accordance with the above standards. So, I do charge a fair and reasonable flat rate to cover additional shipping costs. Whether the drive is a 1TB SATA with 3000 days or a 16TB SAS with 100 days, both are shipped the same.
**Shipping Service**
The second part of shipping is choosing the service. I recommend UPS because of recent service issues with USPS, ranging from severely overdue deliveries and unreliable tracking data to the total loss of an item.
