Let us continue with the benchmark results.
SATA2 drives are currently tested with an ASRock M3A790GXH/128M motherboard and SATA3 drives are currently tested with an ASRock 890GX Extreme3 motherboard.
At present, Microsoft Windows 7 Ultimate Edition is used as the operating system.
The SSD drive speed was examined and compared with the following benchmark software:
The SSD benchmark values offers a very good reference point of the maximal possible reading and writing performance, the speed with smaller files and the respective access time.
The MX-DS Turbo 120GB Mach Xtreme Technology SSD achieved in AHCI mode the to date highest sequential read performance.
In IDE mode however in spite of correct SSD alignment it reached like the ADATA S511 and Crucial C400 a much slower performance.
Additionally the TRIM procedure of the SandForce 2281 controller is not as easy comprehensible.
The administration of the Dirty Cells is controlled in the background by the sandforce controller chip.
With other SSDs one can do a direct TRIM by filling and erasing the SSD data, but with the MX-DS Turbo SSD there was no recognizable TRIM after filling and erasing the cells procedure for cleaning the so-called “dirty cells”.
In IDE mode the SSD exceeded with approximately 346 MB/s the maximum transfer rate of the Serial ATA 2.0 interface, so that a SATA3 interface is really the best choice for this SSD.
The write performance in IDE mode reached relatively slow 162 MB/s.
But also in IDE mode the overall score reached very good 310 points, because for example the OCZ Agility 120GB SATA2 SSD reached only 138 points, ADATA S511 120GB reached 311 points, the 256GB m4 SSD reached 291 points and a 256GB C300 SSD reached 290 points.
Here is a Snipping screenshot of the AS SSD benchmark results (SATA3 IDE):
In AHCI mode also another result beneath the read performance was much higher than in the IDE mode and that is the important value “4K-64Thrd”.
4K means that small 4K blocks are read and/or written and with the 4K 64Thrd this is distributed on 64 Threads at the same time.
Thus the benchmark program simulate for example a typical program start.
Since the weighting of this value is very high in the AS-SSD benchmark tool,the total score in AHCI mode is with 491 points much higher than the previous one in IDE mode.
In AHCI mode the Mach Xtreme Technology MX-DS Turbo 120GB reached a very high read performance of 502,06 MB/s and a write performace of 161,23 MB/s which is almost identical to the legacy IDE result.
Who think now about changing its SATA port in the BIOS from native IDE and/or legacy IDE to AHCI, should change first for example (if possible) only one part of the SATA port, where the drive with the operating system is not installed.
Because if one like to save the new Windows installation, one must install the hard disk controller driver before changing SATA mode from IDE to AHCI – alternatively there are also Registry entries for it.
If you like to upgrade from HDD to SSD, you should not copy the content 1:1 only with a tool like Norton Ghost or Acronis Backup.
It is better to install a fresh Windows7 or adjust at least the SSD Alignment.

Here is a Snipping screenshot of the AS SSD iops results to measure the input/output speed (SATA3):
And here is a Snipping screenshot of the AS SSD iops AHCI results to measure the input/output speed, with a drastic rise (SATA3 AHCI):
In order to get an impression of the speed, here is another Snipping screenshot of the AS SSD copy benchmark (SATA3):
Also the AS SSD copy benchmark is much faster in AHCI (SATA3 in AHCI mode):
The comparison of the AS SSD benchmark results is extended with each new HDD/SSD test.
Here we see several SSDs in comparison to the Mach Xtreme Technology MX-DS Turbo 120GB 2.5″ SSD in IDE and in AHCI mode, whereby the diagram is updated shortly with new SSDs.
Currently, the Crucial m4 256GB SSD is at the to of all result, which offered the highest sequential write performance.
Directly followed by the Mach Xtreme Technology MX-DS Turbo 120GB SSD and the similarly build ADATA S511 120GB SSD.
Here is a comparison of the AS SSD benchmark values, which are getting updated with soon coming drives:
The ATTO disk benchmark values gives a very good overview about the write and read rate on different file sizes.
Here we see once again a huge difference between legacy IDE and AHCI, especially with this SSD.
Its read and write (red) performace is in legacy IDE mode nearly identically, but in AHCI we see a much higher read performance.
Here is a Snipping screenshot of the ATTO Disk benchmark values (SATA3):
Compared to this result, the read performance in AHCI mode is significantly increased in all transfer sizes.
Here we see a comparison of the conventional native IDE mode and the modern AHCI mode, which offers beside the higher performance also advantages like e.g. the support of NCQ (Native Command Queuing) and Hot-Plug.
This SSD reached in ATTO to date highest read rate and the to date highest write rate in our reviews.
Here is a Snipping screenshot of the ATTO Disk benchmark values (on SATA3 AHCI):
These ATTO disk benchmark values are compared with a small transfer size of 32KB and a large transfer size of 8192KB.
The bar chart already shows a first comparison to the Hitachi Deskstar 7K1000.C 1TB hard disk drive, OCZ Agility 120GB SSD, Crucial 256GB C300 RealSSD and a few other SSDs, where the best 8192K result is reached by the Mach Xtreme Technology MX-DS Turbo with nearly identical values like the S511 120GB SSD.
Here is a comparison of the ATTO disk benchmark values, which are getting updated with soon coming drives:
With CrystalDiskMark one receives a balanced measurement of the performance with different transfer sizes.
Here is a Snipping screenshot of the CrystalDiskMark values (SATA3):
As seen in the previous 4K-64Threads results, especially the read and write 4K QD32 and the sequential read result is much higher when operating in AHCI mode.
Here is a Snipping screenshot of the CrystalDiskMark values (SATA3 AHCI):
The following diagram shows the CrystalDiskMark results once again compared with other SSDs and platter drives, which are extended step by step.
In the CrystalDiskMark comparison one can see significant differences between the to-date tested Solid State Drives and Hard Disk Drives, where the tested Mach Xtreme Technology MX-DS Turbo 120GB SSD has currently the best read result in AHCI.
Here is a comparison of the CrystalDiskMark values, which are getting updated with soon coming drives:
With HD Tach one can measure the gradient of the performance.
The Mach Xtreme Technology MX-DS Turbo 120GB 2.5″ SSD has in both AHCI and legacy IDE mode very fluctuating transfer rates.
New logical NAND cell access of the SSD controller results in strong varying values with the latest HD Tach Version 184.108.40.206 version.
To compare these results with SATA3 IDE values, you can move the cursor over this MX-DS Turbo 120GB SSD SATA3 IDE link.
Furthermore you can move the mouse over the following drives to see their respective benchmark results:
ADATA S511 120GB SSD at SATA3 AHCI, ADATA S511 120GB SSD at SATA3 AHCI, Crucial m4 256GB 2,5″ SSD at SATA3 AHCI, Crucial m4 256GB 2,5″ SSD at SATA3 crucial C300 64GB 1,8″ SSD at SATA3, Crucial RealSSD 256GB 2,5″ SSD at SATA3, crucial RealSSD 256GB 2,5″ SSD at SATA2, OCZ Agility 128GB SSD, Hitachi 7K1000.C 1TB disk drive and Toshiba MK8007GAH 1.8″ disk drive.
Here is a Snipping screenhot of the HD Tach benchmark values:
The comparison of the HD Tach benchmark results shows the faster reading speed, writing speed and the lower average access time of the Solid State Drive compared to hard disk drives with their much higher access time.
Here is an impressive comparison of the HD Tach benchmark values, which are getting updated with soon coming drives:
Of course, SiSoftware Sandra benchmark should not be missing in this test series.
SiSoftware offers with their SiSoft Sandra program a very comprehensive tool, which contains a lot of tools to get very reliable test results of all hardware components.
The average access time of the Mach Xtreme Technology MX-DS Turbo 120GB SSD was in SiSoftware Sandra with 50us (equal to 0.05ms) low.
The drive index was in IDE mode 338,76 MB/s and in AHCI mode very high 495,43 MB/s.
