Hard disk caching scheme based on Marvell 88SS9174
The Overview of the large-capacity SSD caching solution
The Adrenaline Solid State Cache Solution uses the same mastering solution as the m4 SSD, Marvell 88SS9174 main control chip, with a capacity of 50GB.
The functional definition and performance indicators：1, The main control program Marvell 88SS9174 main control chip;
2, the capacity is 50GB
The core advantage of scheme：
You only need to install the Adrenaline Solid State Cache Solution software to use it as a high-capacity cache for mechanical hard drives.
Marvell 88ss9174-BJP2 SSD processor introductionBased on the Marvell 88ss9174-BJP2 SSD processor, the RealSSD-C300 is critical to becoming the industry's first SATA-6G consumer solid-state drive.
Similarly, the C300 is also the first to use SSD ONFI 2.1 synchronous NAND flash.In many ways, the Marvel SSD board follows several previous product designs.
As illustrated in the top view above, you will notice that printed circuit boards (PCBs) utilize dense components to lay out micron NAND flash modules.
The Marvell 88ss9174 SSD-controller has few electrons to fill the remaining area. Marvell's 88 ss9174 SATA-III SSD processor incorporates sixteen NAND flash modules and a buffered DRAM chip.
Although only a 256 gb capacity has been revealed, the RealSSD-C300 is crucial.
The key RealSSD-C300 CTFDDAC256MAG-1G1 solid state drive model used in the Marvell 88 ss9174-bjp2 processor architecture.
The Marvell 88 ss9174 supports the Local Command Queuing (NCQ) 32 command slot. Similar to other modern SSD controllers, the Marvel 88 ss9174-bjp2 processor supports native trim and secure erase commands.
Marvell 88SS9174-BKK2 master
Marvell's 88SS9174-BKK2 first appeared on the M4 series of magnesium. When it first came out, the maximum read/write speed was only 415/260 MB/s. It was the fastest SSD on the market at the time. Later, Magnesium released 0009. Firmware to increase its sustained read speed to 500MB/s.
Compared with the old BJP2 stepping, the new BKK2 step master is optimized for 8K page, and the 25nm NAND is better. There are many vendors on the market using this master. There are performance differences between different manufacturers. The best performance in terms of performance is ORICO's HM1 series, with a maximum read/write speed of 500/440 MB/s and an IOPS of 70,000/65,000.
The main control supports SATA 6Gbps interface, supports Trim, NCQ and garbage collection. Trim and garbage collection are good. When the system supports Trim, the performance of SSD can basically be kept in the factory for a long time.
The main products used are: Crucial RealSSD M4 series, Plextor M2P, M2S, M3 series, ORICO HM1 series, Corsair Performance Pro series, Intel 510 series.
