The Sanctum heeft een review van de 10.000rpm IBM Ultrastar 9LZX, de top wat betreft de Ultra2 SCSI schijven en de grote concurrent van de Seagate Cheetah. De performance van het ding is errug hoog (net zoals z'n prijs bdw 
):
The first thing we noticed when running the UltraStar was the stealthy noise it emitted. Even in full out installs we hardly heard a noise from it. Also it's sheer speed was amazing. Even coming from Seagate's speedy Cheetah it was a large difference. Most of it was likely from the difference in buffer cache sizes. The UltraStar packs with a 4MB cache which helps in many different ways. While the drive is performing functions, it can read ahead and keep information stored in the cache, before wasting time in system memory. You can really see this in action, when installing software. Watching the install percent, you can see it jump from say 10% to 14%. This also assists in audio and video i/o, making the Ultrastar a good role for audio and video production.
