GSkill Falcon 128GB SSD review - SSD Performance HD Tach 3.0.4.0

HD Tach 3.0.4.0

HD Tach is a physical performance hard drive test that uses a special kernel mode VXD to get maximum accuracy by bypassing the file system.

The HD Tach sequential read test is a little bit different from other benchmarks. Most benchmarks create a file on the hard drive and test within that file. The problem is that modern hard drives use a zone bit recording technique that allows different read speeds depending on where the data is located. Data on the outside of the drive is much faster than data recorded on the inside.

Obviously for SSDs this is not an issue. We reach the advertised performance perfectly. And again, we expect the Vertex to perform the same, if we'd have had the newer firmware.

In addition to sequential read performance, HD Tach tests the drive's random access time. Random access is the true measure of seek speed. Many drives advertise sub 10 millisecond seek speeds, but seek speeds are misleading. Also again, without a physical head that needs moving around, the SSDs are just soooo fast as they have no mechanical moving parts. Here obviously .. the smaller number is better, 0.1 ms (!).

G.Skill Falcon SSD review

Here's a little test report of HDTach in both a long READ and WRITE sequence as well. Sickeningly fast results really.

GSkill Falcon 128GB SSD review
G.Skill has a product here that they should be very proud off, as they made a touch choice, they also are moving towards the all new Indilinx Barefoot controller inside that SSD drive. As such they can fight off the small-block size issues plaguing SSDs based on the JMicron controllers. This product as that phat 64MB cache inside the falcon to deal with it, and combined with Samsung NAND flash modules we reach over 250 MB/sec read speeds and get this, 190 MB/sec write speeds.
