Thread: Indilinx Barefoot and SLC: Solidata K5

Solidata, a company that produces SSD (like many others) offers a model with the controller flagship of the day - Indilinx Barefoot - SLC and memory, as the Vertex EX OCZ. Does this memory, expensive, really improve performance?

Yes, but the price is accordingly

The answer is yes: a Solidata K6-based MLC and Solidata K5, based SLC, are not equal before writing. Initial tests show that reading rates are essentially identical (approximately 205 Mb / s) but only in writing, memory SLC is to his advantage, where a model based MLC reached 160 MB / s sequential write (approximately) and 10 to 12 MB / s random writes files of 4KB, the SLC model is 220 MB / s sequential and almost 35 MB / s for 4KB random. Even if some are better on this point (including Intel with its X25-E), performance is very high and companies who work on databases (for example) will be interested in this type of storage device. Is the price: a DSS based Barefoot and 64GB MLC is about 180 € in France (at best) and even in the SLC (the Vertex EX is the only one available) is offered at more than 550 € (650 € at least for a X25-E). The Solidata K5, in countries where it is available, it is about 500 €.

In fact, the price difference is too great to justify the difference in performance and the SSD-based memory SLC are therefore reserved for a public professional or hobbyists.
