WD Purple Pro WD181PURP 18TB 7200 RPM 512MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive - OEM

Pros: Seller did a great job shipping the item. Came in an air pack bag surounding the drive in a new sealed foil packaging. As with all drives, bumps do not do them well. Plugged it in and it started immediately. Side note: Seller requested a review of their packaging measures which shows they care about their products and customer service. I've ordered lots of parts on Newegg and this was the first time a seller actually followed up about their product.

Cons: Drive is louder than the seagate it replaced when writing files.

Overall Review: Overall drive works as it should.

Pros: Plug and play or record. Working OK so far.
