Western Digital's newish VelociRaptor SATA hard drive speed tests when configured in a 3 drive RAID-5. The burst speed recorded was robust 598MB/sec, according to HD Tach, which is about on par with what we've seen from WD's Raptor WD1500 line in this configuration. However, average read performance is through the roof, with a 209.4MB/sec land speed record set for what we've seen in our labs and about a 33% performance gain over what we've seen with Raptor WD1500 drives in RAID 5 on the Areca controller. Finally, random access clocks in at a snappy 7.2ms. Damn!
OCZ SATAII SSD (solid state drive) vs. VelociRaptor. Very interesting. The VelociRaptor holds its' own pretty well against the SSD in most things, but does get absolutely smoked in some situations. I'd still take the VelociRaptor at this point, but SSDs are definitely coming on. But why oh why did WD make the VelociRaptor with that weird connector that won't fit inside a hot swap tray (i.e., why can't you put it in most servers????)
And on that note, Wester Digital introduces 2.5'' 10,000 RPM SATAII VelociRaptor for enterprise (this is without the weird heat sink attachment that made the previous drive into a 3.5'' form factor.) Up to 300GB. Unfortunately I can only use 3.5'' drives in my present setup. Seems like it might be possible to make them fit, but I'm not sure I need one bad enough to start drilling holes in my drive sleds. Sweet drive though.
