Seagate ST3500418AS software HD Tune:


Samsung HD502HJ software HD Tune:


As we can see maximum and average transfer rate are much better for Samsung. Only disadvantage for Samsung in it's minimal transfer rate is 5 times lover then Segate.

We can get more details about Samsung HD502HJ with HD Tach software two simple tests.

Software HD Tach Samsung's HD502HJ quick test:


Software HD Tach Samsung's HD502HJ long test:


As you can see the difference in read and write is about 20MB/sec in favor of Samsung as the access time is shorter in the design of the Samsung.

Time for a comparison of the two drives in RAID 0:

To begin with two Seagate ST3500418AS as RAID 0 test with software HD Tune 2.55:


The growth speed of read / write more than double.

Two Samsung HD502HJ as RAID 0 test with software HD Tune 2.55:


As we can see both RAID 0 solutions has much height transfer rates then single drives. RAID 0 based Samsung solution has better maximum and average transfer rates and over 2.5 times better minimal transfer rate then Seagate RAID 0 solution.

Again we can get more details about about both RAIDs with HD Tach software and it's two simple tests – we run each test for each RAID (RAID 0 recovery)

Again we see that the Samsung is faster and a lot of places because of a lot more than 20MB/sec.

With software "Intel Matrix Storage Console" you can turn on the "Write-Back Cache" which in theory should we accelerate our matrix:

Seagate ST3500418AS as RAID 0 with enabled Write-Back Cache test with software HD Tune 2.55:


Samsung HD502HJ as RAID 0 with enabled Write-Back Cache test with software HD Tune 2.55:


We can see the Write-Back Cache increases all transfer rates properties. What is most visible for Seagate hard drives based RAID 0 solution, the minimum transfer rate has much increase – it's doubled!

The Write-Back Cache option accelerates both matrix. Lets have more details again with HD Tach software.

2x Samsung HD502HJ w RAID 0 as RAID 0 with enabled Write-Back Cache software HD Tach long test:


As you can see growth in "power" in Software HD Tune for Samsung is marginal, it is better here falls who wrote about Seagate 5MB/sec growth.
The Software HD Tach results are the same in both. Also the Software with enabled Write-Back Cache we note the very large increase in Burst Rate.
As can be seen from the above comparison, "Samsung HD502HJ" is faster and as a single drive and two drives in a RAID 0 from the "Seagate ST3500418AS" an average of 20MB/sec. For this, if you stand before choosing to buy a new drive will be faster then the Samsung solution.
