At the current moment the performance of an SSD drive is largely determined by its controller and firmware and is almost unaffected by the brand of its flash memory chips. It is the controller, the number of channels it supports, its ways of interacting with memory and its load optimization algorithms that determine the SSD’s top sequential speeds as well as its performance at random writing, which is the most difficult operation mode for flash memory.
In our previous SSD-related reports we paid much attention to products with controllers from Intel (both of the first and second generations) and Indilinx (with different firmware). We also tested SSDs with Samsung’s controller, e.g. the OCZ Summit. Up till now, we have only omitted to test widely available SSDs with a JMicron 602B controller. We will do this test now and will also throw in an Indilinx-based Corsair X128 and a couple of earlier-tested products.
Apacer AP64GS25SSD1, 64GB
As soon as SSD controllers had got more or less mature, there appeared a lot of various products based on them. Many companies seized the opportunity to enter a new and promising market. Quite expectedly, the foremost of them were the makers of other types of flash memory products as they only had to adapt to the new controllers and order/manufacture new product casings. Thus, Apacer came up with a series of MLC-based SSDs with JMicron’s controller. We’ve got a 64GB sample.
Corsair Extreme X128, 128GB: CMFSSD-128D1
We already tested a Corsair-branded SSD. It was the Corsair P128 model from the Performance series which had a Samsung controller inside. Today, we’ve got an Extreme series, Indilinx-based, 128GB model called X128.
