disco duro ssdHow do I add an SSD to my laptop?
hard drive SSD OEM disco duro ssd I have written extensively about SSD disco duro ssd, a friend left a message saying M.2 SSD Although gooddisco duro ssd, but I am a notebook, I can’t use it.” Laptops are known for their small size, most notebooks only have a 2.5-inch hard disk space, must have installed the hard disk, many are still mechanical hard disks. Even the SSD is also A SATA interface, can not use the latest NVMe technology:
in fact, the current notebook motherboards are with M.2 interface, you can install an M.2 SSD yourself.
most notebooks,M.2 SSD open the back cover to see the M.2 interface:
there are some notebooks such as Lenovo, very intimate can be expanded memory slot and M.2 slot into a convenient open cover:
Before installing the M.2 hard drive, determine whether the motherboard and the M.2 hard drive are compatible. Reference 1 is a list of compatibility situations for some notebooks on the market, but it is older.
here to introduce the types of M.2 SSD interfaces, basically divided into two types:
NVMe SSDs are only M notch; Mainstream SATA SSDs are B+M or only B.
and the slots of the motherboard have several cases: only B Key, only M key, and both B Key and M Key.
first only M-notch SSD and M Key-only motherboard representatives support PCIe 4 Lane, so it must be supportive of NVMe (there is an M/B gap is the kind of SSD that takes the AHCI protocol, basically equivalent to a PCIe SSD device, which is now obsolete). Basically compatible.
first only B-notched SSDs and only B Key motherboards represent support representatives to support PCIe 2 Lane or SATA, because AHCI’s SSDs are basically obsolete and generally compatible.
if the motherboard is M+B key, the M-notched SSD cannot be plugged in. Only M + B gap or B gap SSD, 【M.2 SSD】the mainstream is to take the SATA interface, basically no problem.
the more troublesome thing is that when the M Key is listed on the main board, the M+B notched SSD can also be plugged in, and only the M-notched SSD can also be inserted. At this time, you must check the motherboard instructions to determine not to buy the wrong, some motherboard BIOS has been set, can be plugged in, will be dynamic detection, which can also be found in the motherboard instructions.
a simple summary:
also pay attention to the length, M.2 hard disk has a variety of lengths:
some notebooks have limited space, can not insert the longest SSD, need to pay attention before purchasing.
another point is that the wifi card on the notebook motherboard is E Type, it cannot be plugged in, do not plug it hard, and damage the slot.
the M.2 hard drive, and everything seems to be fine. In fact, there are still some things to deal with:
my notebook turned out to be a 160GB SSD, and the space was stretched. In a fit of rage, I installed a 512GB M.2 SSD, which is now much cooler, but unfortunately it is almost full again.
