These were node cache drives in some Dell Isilon servers I purchased. Drives have power on time of roughly 4 years 75 days with 0% endurance use showing from the smartcl export which will be included with each drive. Servers were from a higher education institution surplus sale I bought, and were in excellent condition including being on the original shipping pallets so I'm guessing they sat powered on but unused. Drives will be individually bubble wrapped, shipped within 2 business days, and insured at purchase amount.
