Storage/SSD by stefan @ 2014-06-16
Despite the fact that we are dealing with a 240GB SSD, KingFast is proposing a very low price point of $124 for the drive and for this we get 20nm Micron MLC NAND Flash, a JM667H controller which is able to provide decent read/write performances but also 256MB of DDR3 for caching purposes.
On the side of the unit we will be able to spot a small warranty sticker:
The bottom side of the enclosure is made of aluminum, similar to what we have found at Intel SSDs; here we will also spot a small sticker with the product serial number, full product code name and power rating:
After removing the top cover with a little bit of difficulty, we will be able to reveal the PCB, which features no less than seven mounting holes, six which are used and this method is advertised to increase durability in case of extreme vibration:
While the bottom side of the PCB was mostly empty, the front houses the controller, DDR cache memory and also four MLC NAND Flash chips. On the board we will be also able to spot no less than 5 tantalum capacitors which will be able to store a bit of power in cause of an outage, so data won’t be lost:
For the first time we are spotting the JMF667H controller inside a SSD which contains inside a high-speed ARM9 CPU with 4K page file and 20nm ONFI Flash support. The maximum supported NAND capacity is 256GB:
A single 256MB Nanya NT5CB128M16BP-CG 1333MHz DDR3 memory chip is used as flash:
Each 64GB Micron NAND employs 20nm IMFT technology:
