Samsung 470 Series 128GB SATA2 2.5" SSD Review
The introduction ...
In this review at ocinside.de the Samsung 470 Series 128GB SSD is compared against some SSDs of ADATA, Crucial, Mach Extreme Technology and OCZ.
Since it is a SATA II SSD, it surely will not be able to keep up with the top 6 Gb/s drives, but let us take a look at some benchmark results, to see what Samsung can get out of the 30nm memory in combination with their Samsung controller.
Thanks for the support ...
Many thanks to Samsung for the support with the Samsung Series 470 128GB 2.5" SSD.
The Samsung 470 Series 128GB SATA2 2.5" SSD MZ5PA128HMCD has at present a price of approx. 160 Euro (09/2011).
The 470 Series SSD 2.5-inch series contains at present the following types:
Here you can buy the Samsung SSD for a low price.
Samsung 470 Series 64GB MZ5PA064HMCD
Samsung 470 Series 128GB MZ5PA128HMCD
Samsung 470 Series 256GB MZ5PA256HMDR
Whereby the performance of this Samsung Series 470 SSD Series alters depending on the capacity like the previously tested Crucial C300 or Crucial m4.
A higher capacity of this Samsung 470 SSD has a higher write performance.

SSD firmware update ...
Usually we update the firmware of the SSDs before we begin with the tests.
To the point of testing time however no new firmware was found at Samsung, so that for all tests the original firmware version AXM09B1Q was used.
Benchmark values and test results ...
Let us continue with the benchmark results.
All drives are currently tested with an ASRock 890GX Extreme3 motherboard in Legacy IDE and AHCI.
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:
AS SSD benchmark result ...
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.
In IDE mode the SSD achieved with approximately 251 MB/s nearly the maximum transfer rate of the Serial ATA 2.0 interface.
The ASSSD write performance in IDE mode was approximately 235 MB/s, which is a good result for a SATA2 SSD.
Also the overall score of this Sasmung S470 reached in IDE mode good 208 points, in comparison for example the OCZ Agility 120GB SATA2 SSD reached 138 points, the 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 (SATA2 IDE):
In AHCI mode the read performance was nearly identical to the IDE mode results.
But one value was also on this SSD much higher 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 316 points much higher than the previous one in IDE mode.
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 (SATA2 IDE):
And here is a Snipping screenshot of the AS SSD iops results to measure the input/output speed, with a drastic rise in AHCI (SATA2 AHCI):
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 Samsung 470 Series 128GB 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.
Of course, the performance of the SATA2 SSD does not reach the SATA3 SSD results, but at present is Samsungs' 470 Series 128GB SSD in the upper third of the benchmark chart.
Here is a comparison of the AS SSD benchmark values, which are getting updated with soon coming drives:
ATTO Disk benchmark result ...
The ATTO disk benchmark values gives a very good overview about the write and read rate on different file sizes.
With the Samsung SSD 470 one can see a difference between legacy the IDE and AHCI mode, which is not as high as with the SATA3 tested before.
One could operate Samsung S470 128GB thus quite still at an older SATA2 controller without AHCI and would determine only a small difference on daily work.
Here is a Snipping screenshot of the ATTO Disk benchmark values (SATA2 IDE):
Compared to this result, the read and write performance in AHCI mode is a little bit increased on all transfer sizes.
Here is a Snipping screenshot of the ATTO Disk benchmark values (SATA2 AHCI):
The 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, the OCZ Agility 120GB SSD and the Crucial 256GB C300 RealSSD and a few other SSDs, whereby the Samsung 470 series can be found mainly with the 8192K result at the lower part of this chart.
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 (SATA2 IDE):
As seen in the previous 4K-64Threads results, the read 4K QD32 is much higher when operating in AHCI mode.
Here is a Snipping screenshot of the CrystalDiskMark values (SATA2 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 of the Solid State Drives and Hard Disk Drives, where the tested Samsung 470 Series 128GB SSD reached the lower third of the chart.
Here is a comparison of the CrystalDiskMark values, which are getting updated with soon coming drives:
HD Tach result
With HD Tach one can measure the gradient of the performance.
The Samsung 470 Series 128GB 2.5" SSD has in both AHCI and legacy IDE mode very smooth transfer rates and extremely fast access times of approx. 0.1ms known from most SSDs.
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:
SiSoftware Sandra benchmark result
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 Samsung 470 Series 128GB SSD was in SiSoftware Sandra with 70us (equal to 0.07ms) low.
The drive index was in IDE mode 247.62 MB/s and in AHCI mode nearly identical at 247.13 MB/s.
Here is a Snipping screenshot of the SiSoftware Sandra benchmark values (SATA2 IDE):
Here is a Snipping screenshot of the SiSoftware Sandra benchmark values in AHCI mode (SATA2 AHCI):
Here is a comparison of the SiSoftware Sandra benchmark values, which are getting updated with soon coming drives:
Result and general impression ...
The Samsung 470 Series 2.5" 128GB SATA2 SSD MZ5PA128HMCD achieved a solid performance in both Legacy IDE and AHCI.
The Samsung 470 Series EU MZ5PA128HMCD 128GB MLC Solid State Drive with Samsung Controller and 30nm Samsung NAND is tested both in the more current AHCI mode and in legacy IDE mode, whereby the AHCI mode showed compared to previously tested SATA3 SSDs only marginal performance advantages.
The read and write performance benchmark values achieved in legacy IDE and AHCI nearly identical values, so this SSD can be operated also at an older SATA2 controller without AHCI, but with lower 4k values.
The Microsoft Windows 7 Ultimate boot procedure from start screen to login screen only 9 seconds and the Windows 7 performance index reached 7.6 from 7.9 possible points.
All in all this Samsung 470 Series 128GB SSD achieved for a 3Gb/s SATA SSD good values and reached nearly the maximum possible SATA2 performance.
Currently the prices for some SATA3 drives are very close to the SATA2 Samsung Series470 SSD, so in case of a newer PC-System with SATA3 controller it would be more recommendable to buy a SATA3 SSD.
