The 64GB C300 is up against some very healthy competition. It is the only drive in our comparison that's under 120GB in capacity. What's more, it's less than half the price of the other SSDs. We'll be adding other sub-100GB drives as they come in for review.
We use a Seagate 1TB mechanical hard drive, housing the operating system. The benchmarked drives are connected to the motherboard's ICH10R 3Gbps controller should they use SATA2, or the Marvell 6Gbps connector if they're SATA 6Gb/s. The Crucial RealSSDs are both connected to the Marvell controller. All are used as secondary/storage mediums for the first five tests.
HD Tach's full variable-zone read/write test is used to write to the drive(s)' blocks and therefore bring the benefits efficient garbage recycling into play. We run this test first to mimic the wear a drive is likely to have during day-to-day operations.
CrystalDiskMark provides throughput data based on sequential reads and writes, and random (512K/4K) reads and writes. We've used the default 1,000MB file-size for the tests.
Iometer is run by using workstation and database patterns for queue depths (outstanding I/Os) of two and 32, representing very light and moderate loads. Drives with efficient NCQ functions will see performance increase as the queue is deepened.
PCMark Vantage spits out a bunch of data on the relative speed of the drive(s) when undertaking common tasks.
The file copy test involves copying 8.83GB of data back on to a different folder on the same partition, stressing the read/write ability of the drive.
Copying an exact image on to the test drives and using them as the main boot storage, we time how long it takes to load Windows 7 and, once within the operating system, the train level within Crysis, as used in our graphics-card tests.
