Dell ST2000NX0403 2TB 7200 RPM 2.5 inch Internal Hard Drive - CK3MN. Pulled out of a working Dell PowerEdge server with all testing healthy. Every unit is essentially identical except for the serial number. All units have passed SMART test via Seagate SeaTools. Every unit will be shipped in an antistatic bag, bubble wrapping, and secure transport. These are fantastic as they use SATA interface instead of the enterprise standard of SAS. This means they are compatible with consumer grade hardware using SATA, such as pc, mac, and any compatible device with proper adapter. These units will ship WITHOUT the dell caddies that slide them nicely into the server. They are cosmetically in perfect shape and look essentially brand new. They all spin up and run extremely smoothly, no rattle or weird noises. The drives were used in a PowerEdge t630 as home based server storage, always on uninterruptible power supply and never hot swapped. They all have a manufacture data on or right around January 2017 and are from the same lot originally put into this server. Every unit will be retested on SMART test and have its serial logged to verify function just prior to packaging. Shipped out of Salt Lake City, Utah. Shipping is fast and free, including drop-off to USPS within 24 hours of payment.
