“The Seagate Cheetah 15K.7 is a remarkable product, no matter if you see it as an enterprise tool or through the eyes of an enthusiast...”
- TweakTown, November 2009
|
|
“In conclusion, the Seagate Cheetah 15K.7 SAS drive has demonstrated a dominance over existing Enterprise storage solutions and improved file transfer speeds at the same time as it saves electrical energy costs.”
- Benchmark Reviews, October 2009
|
|
“So after taking a look at the Seagate Cheetah NS.2 and Cheetah 15K.7 I can say one thing without a doubt, these are two of the fastest hard drives we have seen. In fact the 15K.7 is just short of SSD performance with the reliability that only 53 years of development can give you.”
- Lanoc Reviews, October 2009
