Some of us are going to wish we had deeper pockets after reading this. The folks at Hot Hardware have grabbed three new VelociRaptors for the purpose of testing performance in RAID 5, and although the results attained were somewhat expected, you still can't help but admire just what these little 2.5" speed demons are capable of.
Using HD Tach, the array pushed out an incredible burst speed of 598.2MB/sec, and more importantly an average speed of 209.4MB/sec. This equates to roughly 33% better performance over a WD1500 Raptor array; but you'll certainly be required to pay a pretty price for a setup like this. One can dream.
If you were the type to think of 2.5" drive technology only in terms of notebook products, then recently, Western Digital probably helped expand your horizons a bit. With the release of their VelociRaptor 300GB SATA hard drive, mainstream users were exposed to the advantages of the high transfer rates associated with 2.5" platters rotating at 10K RPM, with four access heads pulling data. Though packed in a 3.5" form-factor for desktop system compatibility, the 2.5", dual 150GB platter platform that the VelociRaptor was built on allows it to outperform virtually all standard 3.5" SATA drives on the market today, even WD's 10K RPM Raptor WD1500 series.
