The original Raptors of yesteryear stole some of the best aspects of SCSI technology there was to offer and brought them across to SATA-land, where in particular it's rotational speed of 10,000rpm gave a 40% throughput and access time benefits over the more traditional 7,200rpm drives. Spinning the platters faster is only one way of speeding up overall disk performance.
Earlier Raptors were offered in 36 and 74GB, respectively and offered as little as 37GB per platter. Now we're seeing disks with as much as 160GB per platter (or something like that). Which offers four times as much data packed into the same area can benefit performance more than spin speeds. With their greater areal density, standard 7,500rpm drives have been getting closer to the Raptor's sustained throughput and have far exceeded it in terms of storage capacity.
Enter...Raptor X.
The new Raptor comes in two flavors...the standard 150 and the X edition, the latter sporting a clear window so you can enjoy looking at it was disk operates in full bloom. The Raptor X has three key improvements...areal density, capacity and cache. 75GB/s per platter for a total of 150GB, and a 16MB cache and it still uses the 150MB/sec SATA interface.
HD Tach 3 RW results are mindblowing...with an average read throughput of 88.8MB/sec which is 24MB/s faster than the 74GB Raptor, in regards to inner and outer zones, reading hasn't dropped below 58MB/sec. Writing hasn't dropped below 51.7MB/sec. The new Raptor is currently the fastest HDD on the market today with a half second lead in Far Cry loading over the 7200.9 Barracuda.
If there was a time when you ever wondered how a hard drive did what it did, here's your chance to finally find out.
