You can't just post the numbers and compare. You have to think. I have an Intel X25-M 160GB drive that I bought new in 2009 for $550 and it's seen daily use. I'd call it average use, no video or photo editing. I have 18.3TB lifetime host writes on the drive. 72TB is more than enough for the average Joe Shmoe on this site that plays games and browses the internet. It would only be a concern if your job entails video/photo/3D editing. Speeds are good too, removing the SATA bottleneck is big. Writing that 1TB drive 72 times over to completion just won't happen, it will probably die first and I'd be surprised if its lifespan is as long as this X25-M. This drive is a no brainer for everyone except heavy content creators who do it for their day job.

how about black pcb
