Testing – HD Tune Pro
HDTune Pro is one of the most popular hard drive software suites available. It has many different benchmarks and tests built into it. Our first test is the read benchmark, which tests the average read speed and access time of the drive.
Good results here, you can see there is hardly any fluctuation at all, which means the drive will stay at the same speed when you are reading data from it. Up next we have HD Tune’s write benchmark.
Good results here as well, one of the faster drives we have tested in this test.
Now we have the Random Access test. This test measures the performance of random read and write operations. Tests are taken in 512b, 4KB, 64KB, 1MB, and random file sizes. The performance of the drive is reported in operations a second (IOPS), average access time and average speed. Here are both the results from the read and write random access tests.
We normally like the see 5000 and over in the 4K test. You can see that it exceeded that in both the read and write tests.
In HD Tune Pro 5.0 the file benchmark is actually 2 tests now. The first is the normal file benchmark we are used to see that tests different transfer speeds over specific file lengths.
The newly added file benchmark also tests a file size (500MB for our test) and gives you sequential read and write speeds. It also gives you IOPS for 4KB random single and 4K random multi.
As you can see from the above graph the drive performs right up to specifications.
HD Tune also has a set of extra tests. Here are the results of those for both read and write.
RIDICULOUS lasted 20 hours and died
This drive is junk 11-20% FAILURE RATE RIGHT OUT OF THE bOX
Also Adata make YOU pay Shipping for the RMA !
and then I got back a refurbished unit with the tamper seal broken
now my 3 year warranty is void
Customer service line is a recording I call and leave name and number 3 times and never get a call back
Check amazon and newegg these Adata Clowns have to be aware these drives die right out of the box Look at all the 11-20% bad reviews about it dieing right away YEt they do nothing except mess over their customers void their warranty and send them a refurbished unit that the customer pays shipping RIDICULOUS
NEVER BUY ADATA PRODUCTs
Absolutely, this drive is a joke. My second sp900 Died after 1 month of NORMAL usage. I had to return the first one, because it was very slow. I was absolutely sure that the chips are fake. The retailer didn’t believe me however. They replaced it with another sp900 with 5.0.7a firmware with signature not even present at the manufacturers list. To prove my theory (that the drive is not even close with the ones from reviews) I had to open it. The board circuit inside had nothing to do with the ones reviewed. I’m absolutely sure that A-DATA did a marketing trick with passing some good ones for reviews and flooding the marked after that with crappy ones that not even use micron chips! Stay away from that junk!
