It can be seen in all these tests that the major difference between SSDs is in reading and writing efficiency in addition to adopted Flash chip specifications (form, node, speed). Multi-channel access and wear leveling technologies also influence the efficiency of SSD controllers.

Nand Flash chips used in the SSD are divided into higher priced SCL, and lower-priced MLC. The former is suitable for writing data, while the latter shows better performance in reading data; the downside of the MLC is its shorter lifespan and that it requires SSD controller to provide better algorithms to enable MLC SSD Flash chips to write data uniformly, in order to extend its service life.

There is a variety of SSDs for use in servers, such as PCI-E SSD or 2.5” SATA interface SSD, either based on SLC NAND or MLC NAND, sometimes even utilizing DRAM. Our test focused on one server SSD--HugeTech Server One 1200 200GB SSD. Meanwhile, we also observed the performance of DRAM-based ACARD ANS-9010 32GB SATA Dynamic SSD, which is equipped with 32 GB DDR2 and SATA interface as well as a battery for memory assistance(CF Card) in case of DRAM data loss during power failure.

A total of 40 SSD products were listed in the evaluation, mostly MLC SSDs with capacities of 64GB and 128GB. In the evaluation, we also compared the differences between SLC NAND Flash and MLC SSD, as well as the differences between SSD controllers.

Most SSDs of 128 GB class are 128 GB in size but there are also 120 GB and 200 GB products for evaluation this time. The storage capacity class can be used as the main hard disk as well as the boot disk or main disk.

|
|
Most SSDs of 64 GB class are 64 GB size but there are also 60 GB and 80 GB products for evaluation this time. The storage capacity class mainly targets notebook users, who do not need larger capacity. It is also suitable as desktop boot system disk.

After publishing SSD Evaluation List in 1H2009, we continue to test the performance of new generation SSDs in 1H2010. The number of SSD products and makers has far exceeded that of last time. We have classified them into 64GB and 128 GB groups based on storage capacity. Moreover, we have divided SSD groups based on controller ICs for evaluation and compared the differences between SSDs using SLC and MLC NAND flash.

Since launching the SSD report series earlier this year, we have been testing the SSD products on the market from different vendors. This time, the Falcon 128GB SSD from the well-known electronics supplier G.Skill has captured our attention. According to G.Skill, the Falcon series SSD boasts high efficiency disk storage feature and provides a better storage preference for desktop PCs and Notebooks.
