Corsair F100 Force 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.
With this test we NEVER reach advertised speeds, so please don't worry about that. It is the nature of the test.
When we look at write performance we still get close to 148 MB/sec in this test, and that's not okay for this drive. We are missing a good chunk of performance somehow.
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 so fast as they have no mechanical moving parts. Here obviously .. the smaller number is better, 0.1 ms.
The Corsair K70 RGB Pro keyboard is the one we’re reviewing today. It’s not the first one from the K70 series checked on guru3d. Previously those were K70 RGB Rapidfire Mk2, also in a low-profile version, and as a TKL, so overall, there shouldn’t be any significant surprise as far as the general concept goes. Corsair K70 RGB Pro takes some K100 RGB and (most of) K70 RGB TKL CHAMPION (already mentioned) features. The suffix “Pro” wasn’t used yet, so probably it was the right time for that.
