HD Tune Pro is a hard disk utility and benchmarking utility for Windows. This tiny application allows you to scan your hard drives in search for errors or take a deeper look at several performance figured coming from the storage unit.
HDTune is the one test that does not like the SF-1200. Weird anomalies, average performance. So here we measure linear read performance of the SSD and as you can see we average out at roughly 226 MB/sec, okay performance, you'll agree with me, but not up-to par to what you'd expect. Your Average HDD would do 45-65 MB/sec here, with a WD VelociRaptor topping is off just over 100~120 MB/sec.
Write performance more shoddier, we know that the 34nm NAND memory is slightly slower. Once we start to measure write performance we see figures reach a continued write performance averaging out at roughly 191MB/sec, that I can not explain though. It's not consistent with the manufacturers advertised specifications.
The latest edition of HD Tune Pro allows random access read and write testing, a feature not available in other software tools. And this is certainly interesting to observe. Over 30 MB/sec on 4 KB files is just great for this particular test application.
Overall very good write IOPS performance. We get 30MB/sec on 4KB files returned. The HDTune results as such should not considered to be objective until either a software update fixes some issues, or perhaps on the SSD side a firmware upgrade solves it.
OCZ Vertex 460 SSD review We review and test the OCZ Vertex 460 SSD series released in 120 - 240 and 480 GB versions. Based on the Indilinx Barefoot 3 controller we test the 120GB NAND flash memory based model. The end result is an ...
OCZ Vertex 450 SSD review In this article we test, benchmark and review the all new OCZ Vertex 450 SSD. Armed with the new Indilinx Barefoot 3 controller this is the fifth incarnation of the popular OCZ Vertex series. Will it be as fast and competitive as it's predecessors ? Well let's see and find out shall we ?
OCZ Vertex 3.20 SSD review In this article we test, benchmark and review the OCZ Vertex 3.20 SSD. What a great and fast piece of technology this is. An 20nm NAND flash SSD that is speedy and actually amongst the the rest of the devices tested, but also mroe affordable. Head on over into the review.
OCZ Vertex 4 SSD review with 1.5 firmware We retest the OCZ Vertex 4 SSD yet now with 1.5 firmware update. , again bringing more performance towards the Vertex 4 series of SSDs. And albeit the difference is not as big as the 1.4 release was, it certainly makes a difference as this article will show you.
