Conclusion

Announcement: Despite the circumstance that the rating of a product is based on as many objective facts as possible there are factors which can have an influence on a rating after publication. Every autor may perceive data differently over time whereas one possible reason for example is a deeper background knowledge or understanding of certain processes. Certain unforseen market conditions as well as changes have the potential to render a descision made at a certain point in time obsolete.

A closer look at the sequential thoughput rates reveals that there is solid performance especially at higher block sizes. Regarding sequential reads we se a maximum value of 498 Megabyte per second. Concerning sequential writes the drive tops out at 522 Megabyte per seconds. When it comes to random IOPS we measured almost 58'000 IOPS for random reads and aobut 23'500 IOPS for random writes. On the box of this drive you can find that the drive should be able to perform 550 Megabyte per second when doing sequential reads and 520 Megabyte per second when it does sequential writes. During our tests we haven't been able to confirm these values. A closer look at the random IOPS shows the impact on performance of asynchronous NAND flash. With synchronous NAND flash you get almost double the random write IOPS compared to what the SMP35 delivers. Overall the SMP35 isn't a bad drive but the fact that the competition which also uses SandForce SF-2281 controlers but synchronous NAND flash is only a tiny bit more expensive. In order to become a success this drive should be sold quite a bit cheaper than the drives that make use of the much faster synchronous NAND flash.
