Summary: I had always wanted a 10000rpm drive since my days of browsing Micro Times in high school. It will be my last mechanical C drive and it's done it's job without any hiccups.
Pros: This has been my primary drive for nearly 5 years and it has performed flawlessly. It's run in a crowded, hot case for much of it's run and I've formatted and reinstalled several times on multiple motherboards.
Summary: I was inpressed by the speed and capacity, and it worked very well for 3 years. Turned it on at 6 or 7 AM and off at 9 or 10 PM for 3 years and 3 months in a stripe pair. Now it is getting reread flags so I tried to re task it but it crawls on restore and fails. So seperate low priority work drives it is. I have replaced it with a pair of Crucial SSD's speed and reliability restored. Lesson? don'd go skimping if you really want the best.
Summary: Please, do the homework, WD makes a VelociRapter with firmware specifically tuned for RAID applications. The many failures you see are usually to do with a desktop drive collapsing from enterprise duty it was not designed for.
Pros: Outstanding Performance, faster than some SSD's! The 2.5" form is great for many mounting options. Quiet!! Spinup sounds a bit like a tubrofan but quickly goes away, seeks are very subdued. Dependable! Spinning since 2008 with no failure or lost data. Two-platter design. lower seek times and less to go wrong.
Cons: Not a true 2.5" FF, unit height is a bit taller making mounting it into a silencer a bit of a challenge. Non-standard connector placement may affect some users.
Summary: Why bother with configuring a SCSI or two drive in raid 0 when this is just as fast and it plug in play. I would use this drive on the OS and program install only and a 2 terabyte for saving content like video pics and docs. \ As far as vs a Solid state drive yes the solid state book faster but who cares the important part is real world use like audio and video conversion real world transfer rates ect...
