Bring on the DRAM
The ANS-9010 arrives empty, so you have to provide your own memory. Today we'll be testing the drive loaded with 16GB of DDR2-800 memory courtesy of OCZ. DDR2-800 is cheap and plentiful these days, and it's often less expensive than slower speed grades that should still provide more than enough bandwidth for a RAM disk. These Gold Series modules can be found in two-DIMM, 4GB kits for as little as $44 online, pegging the cost of 16GB at well under $200. Thanks to OCZ for providing these modules for testing.
Our testing methods
We've assembled motley crew of competitors to line up against the ANS-9010 today. In addition to the fastest mechanical desktop drives from Hitachi, Samsung, Seagate, and Western Digital, we've thrown in a few flash-based SSDs from Intel and Samsung. And since the i-RAM started this whole business of inexpensive hardware RAM disks, we've included it, as well.
To keep the graphs on the following pages easier to read, we've color-coded the bars by manufacturer. The ANS-9010 appears in bright red, and we've tested it in single-drive and RAID 0 configs. In RAID mode, we relied on the RAID feature built into our test system's Intel south bridge.
All tests were run three times, and their results were averaged, using the following test system.

Thanks to NCIX for getting us the Deskstar 7K1000 and SpinPoint F1.
Our test system was powered by an OCZ PowerStream power supply unit.
We used the following versions of our test applications:
The test systems' Windows desktop was set at 1280x1024 in 32-bit color at an 85Hz screen refresh rate. Vertical refresh sync (vsync) was disabled for all tests.
All the tests and methods we employed are publicly available and reproducible. If you have questions about our methods, hit our forums to talk with us about them.
