Show me a 10K RPM with 128 MB cache and we’ll talk. Not saying this isn’t great for the likes of EMC. We’ll be able to get 75 TB of data in a single 25-disk 2.5” SATA III shelf, which is insane, but the seek times for data won’t be astronomical at 7.5K RPM.
I don’t know...My MacBookPro 15” Retina has 768GB of solid state memory....nothing moving in this bad boy....I can live with the smaller memory.
Probably still 80/90 iops though. Unless it is mirrored (which incurs a write penalty) or in a layered volume its not probably not going to be blinding performance.
