Five year warranty, this SDD will outlive most others (or at least it should). New technology, 64 layers of 3D NAND flash. It's too early to to do proper comparisons in terms of longevity but I'm sure it'll last me a while. This 545s 2.5 inch SSD is even faster than my Crucial MX300 M.2 SSD. I got a random read/write 4k speed of 100 MB/s + (with CrystalDisk Mark 5) that's unheard of on a SATA drive. Sure, this isn't NVMe or Optane, but that's okay, for the price ($165) I'm still pretty satisfied with this SSD. [Dec '17 morahman7vn]
