Lenovo k49 solid state drive interface model

What are the sizes of SSDs and what are the interfaces?

The most common is the 2.5-inch 7mm/9.5mm SATA interface SSD. Slightly less common are the mSATA half-height/full-height ones. A little less are NGFF2242/2280, etc. There are also PCI-Express slot SSDs for desktops.

Named because solid capacitors are referred to as Solid in Taiwanese English, SSDs consist of a control unit and a storage unit (FLASH chip, DRAM chip).

SSDs are identical to ordinary hard disks in terms of specification and definition of interfaces, functionality and usage, and are basically identical to ordinary hard disks in terms of product form factor and dimensions (the emerging U.2, M.2 and other forms of SSDs are completely different in size and form factor from SATA mechanical hard disks).

Widely used in military, automotive, industrial control, video surveillance, network monitoring, network terminals, power, medical, aviation, navigation equipment and many other fields.

The operating temperature range of the chip is large, commercial-grade products (0~70℃) industrial-grade products (-40~85℃). Although the cost is high, it is being popularized to the DIY market.

Because the technology of SSDs is different from that of traditional hard disks, a number of emerging memory vendors have arisen. Manufacturers simply buy NAND particles, pair them with appropriate control chips, write the main controller code, and create the SSD.

The new generation of SSDs commonly use the SATA-2 interface, SATA-3 interface, SAS interface, MSATA interface, PCI-E interface, M.2 interface, CFast interface, SFF-8639 interface, and NVME/AHCI protocol.

Lenovo K49A (i73632QM/2GB solo), listed in May 2013, pre-installed with DOS, chipset: Intel HM77, CPU: i7 triple 3632QM, main frequency 2.2GHz, RW 3.2GHz, 35W, RAM 4GB, HDD 500GB, DVD burner, 15.6″ screen, resolution 1366X768, Solo NVS5400M/2GB memory, memory bit-width 128bit, Streaming processor: 96, Collective HD4000, 2.2Kg, Thickness: 18.6-33.6mm, Case: Carbon Fiber, Black,¥ 5900;

The Lenovo K49A series is a commercial machine that uses a professional graphics card, NVIDIAOptimusNVS5400M, which is suitable for 3D graphic design and very poor gaming! The shell of this series is made of carbon fiber, which has a high manufacturing cost, and also indicates that it is a high-end business notebook, which used to have a particularly high price point, for example:

Lenovo K49A (i53320M/4GB/500GB), listed in September 2012, with pre-installed Win7 64-bit Home Edition, chipset: Intel HM77, CPU: i5 3rd generation 3320M, main frequency 2.6GHz, RW3.3GHz, 35W, RAM 4GB, HDD 500GB, DVD burner, 14″ screen, resolution 1366X768, Solo NVS5400M/2GB memory, memory bit width 128bit, stream processor: 96, HD4000, 2.2Kg, thickness: 18.6-33.6mm, shell: carbon fiber

Except for the RWI, which is 0.1GHz higher than this year’s Lenovo K49A (i53230M), and pre-installed with Win764-bit Home Edition, it’s exactly the same, but priced at $2,400 higher!

The high price/performance ratio of this year’s K49A series is evident.
