Haddii aadan ahayn qof farsamo, waxaa laga yaabaa inaadan garanayn farqiga u dhexeeya M.2 iyo NVMe , oo waxaad u qaadan kartaa inay isku mid yihiin. Dadku badanaa waxay ku wareeraan shuruudahan markay raadinayaan inay iibsadaan darawallada SSDs^(SSD) . Soo gaabinta farsamadan waxaa loo isticmaalaa in lagu qeexo SSD^(SSDs) -yo badan , oo waxaad inta badan ku aragtaa darawallada adag ee dawlad-goboleed ee labadaba M.2 iyo NVMe sifooyinkooda^(NVMe) ama magacyadooda moodeelka. Sidaa darteed, way fududahay in la jahawareeriyo oo la rumaysto in M.2 uu qeexayo NVMe ama lid ku ah. Waa kuwan waxa M.2 iyo NVMe yihiin iyo sida ay u kala duwan yihiin:

Waa maxay NVMe?

NVMe ama Memory Express-ka aan isbedbedelin waa is-dhexgal software-heer warshadeed ah kaasoo awood u siinaya SSD-yada iyo qaybaha kale inay si toos ah u dhex maraan ^{(NVMe or Non-Volatile Memory Express is an industry-standard software interface that enables SSDs and other components to run directly through the)} PCI Express (PCIe) interface ka si toos ah ugu xidhan processor-ka kombayutarka^{(physical interface directly attached to a computer's processor)} . NVMe waa beddelka interface-kii hore ee SATA kaas oo loogu talagalay in lagu xidho aaladaha kaydinta iyo Motherboard-yada kombiyuutarka. SATA ma laha xiriir toos ah processor-ka kombayutarka. Qaar badan oo NVMe SSD ah ayaa isticmaala qaabka M.2, sida wadista sawirka hoose.

Markaad iibsato SSD cusub , waxay isticmaashaa mid ka mid ah SATA ama NVMe interface si loogu xiro kombuyuutarkaaga. SATA SSDs - dhaqameedku waxay adeegsadaan qaabka 2.5 ", sida lagu arkay sawirka hoose.

Waa maxay M.2?

M.2 waa nooc ka tarjumaysa cabbirka jirka iyo qaabka kaarka ee lagu dhejin karo booska M.2^{(M.2 is a form factor that spells out the physical size and shape of the card that can be plugged into an M.2 slot)} . Qodobkan foomka waxa loo qaabeeyey si loo kordhiyo booska iyadoo la yareynayo raadka. Booska M.2 waa leydi, oo ballaciisu yahay 12, 16, 22, ama 30 millimeters. Inta badan M.2 wadeyaasha adag-state waa 22 millimitir oo ballac ah. Dhererku sidoo kale wuu kala duwanaan karaa: 16, 26, 30, 38, 42, 60, 80, ama 110 millimeters.

Inta badan Motherboard-yada kombiyuuterka waxay daboolaan dhererka kala duwan ee boosaska M.2. Isla mar ahaantaana, balaadhka wuxuu u eg yahay inuu ku dhejiyo Motherboard kasta, inta badan 22 millimitir. Boodhadhka M.2 ee Motherboard-ka waxay kula xiriiri karaan inta ka hartay PC-ga iyadoo la isticmaalayo is-dhexgal/ standards kala duwan, oo ay ku jiraan PCI Express (oo ay adeegsato NVMe ) ama SATA , oo ay adeegsadaan SSD^(SSDs) -yada caadiga ah .

Motherboard kastaa wuxuu leeyahay tiro kala duwan oo ah boosaska M.2 oo leh astaamo kala duwan.

SSDs , isticmaalkooda NVMe interface, iyo qaabka M.2

Markaad baadhayso dukaamada online-ka ah, waxaad heleysaa labadaba SATA SSDs iyo NVMe SSDs , adoo isticmaalaya mid ka mid ah qaabka caadiga ah ee 2.5" ee ay isticmaalaan jiilalka kowaad ee SSDs , ama M.2 - oo ay isticmaalaan jiilalka cusub ee SSDs . Kingston A400 . SSD -gan waxa la heli karaa labadaba qaabka caadiga ah ee 2.5" iyo qaabka cusub ee M.2. Waa isku mid SSD , oo leh tilmaamo isku mid ah, laakiin leh cabbir kala duwan. Si kastaba ha noqotee, maaha ^(NOT)NVMe SSD , laakiin waa mid SATA ah.

Si aad wax badan u jahwareeriso, waxaad ka heli kartaa NVMe SSDs adoo isticmaalaya qaabka 2.5 ", ma aha oo kaliya M.2. Tusaale waa Kingston DC1000M U.2 Enterprise SSD . Iyadoo adeegsanaysa interface NVMe si ay u bixiso waxqabad sare marka xogta la wareejinayo, Waxa kale oo ay ka dhigtaa isticmaalka qaabka caadiga ah ee 2.5 ".

U^(Pay) fiirso labadaba qaab-dhismeedka iyo is-dhexgalka marka aad iibsanayso SSD-gaaga xiga

Markaad iibsato SSD -gaaga soo socda , u fiirso qaabka qaabkiisa iyo interface-ka uu u isticmaalo in lagula xidhiidho kombiyuutarka. Sharaxadiisu waa inay iswaafaqaan labada boosaska iyo meelaha laga heli karo Motherboard-ka. Sidoo kale, haddii aad aragto SSD oo lagu tilmaamay NVMe , ha u qaadan in uu si toos ah u isticmaalayo qaabka M.2. Sidoo kale, haddii aad aragto SSD lagu tilmaamay inuu yahay M.2, ha u qaadan inay isticmaalayso NVMe . U^(Pay) fiirso qeexitaankeeda faahfaahsan ka hor inta aanad go'aansan waxa aad iibsanayso.

M.2 vs. NVMe: What is the difference when it comes to SSDs?

If you arе not a technical person, yоu might not know the difference between M.2 and NVMe, and you may assume that they are the same thing. People uѕually cоnfuse these terms when looking to buy SSD drives. These technical acronyms are used to describe lоts of SSDs, and уou often see solid-state drives that have both M.2 and NVMe in their descriptions or model namеs. Thus, it is easy to confuse them and believe that M.2 describes NVMe or vice-versa. Here is whаt M.2 and NVMe are and how thеy differ:

What is NVMe?

NVMe or Non-Volatile Memory Express is an industry-standard software interface that enables SSDs and other components to run directly through the PCI Express (PCIe) physical interface directly attached to a computer's processor. NVMe is an alternative to the older SATA interface that was designed to connect storage devices to computer motherboards. SATA does not have a direct link to the computer's processor. Many NVMe SSD drives use the M.2 form factor, like the drive pictured below.

When you buy a new SSD, it uses either the SATA or NVMe interface to connect to your computer. Traditional SATA SSDs use the 2.5" form factor, as seen in the picture below.

What is M.2?

M.2 is a form factor that spells out the physical size and shape of the card that can be plugged into an M.2 slot. This form factor has been designed to maximize space while minimizing the footprint. The M.2 slot is rectangular, with possible widths of 12, 16, 22, or 30 millimeters. Most M.2 solid-state drives are 22 millimeters wide. Lengths can also vary: 16, 26, 30, 38, 42, 60, 80, or 110 millimeters.

Most computer motherboards accommodate a variety of lengths for M.2 slots. At the same time, the width tends to be fixed on each motherboard, usually 22 millimeters wide. The M.2 slots on a motherboard can communicate with the rest of the PC using different interfaces/standards, including PCI Express (used by NVMe) or SATA, used by traditional SSDs.

Each motherboard has a different number of M.2 slots with different specifications.

SSDs, their use of the NVMe interface, and the M.2 form factor

When browsing online shops, you find both SATA SSDs and NVMe SSDs, using either the classical 2.5" form factor used by the first generations of SSDs, or M.2 - used by newer generations of SSDs. To exemplify, let's take a look at Kingston A400. This SSD is available both in the traditional 2.5" form factor and in the newer M.2 form factor. It is the same SSD, with the same specifications, but with a different size. However, it is NOT an NVMe SSD, but a SATA one.

To make things more confusing, you can find NVMe SSDs using the 2.5" form factor, not just M.2. An example is the Kingston DC1000M U.2 Enterprise SSD. While it uses the NVMe interface to deliver high performance when transferring data, it also makes use of the classic 2.5" form factor.

Pay attention both to form factor and interface when you buy your next SSD

When you buy your next SSD, pay attention both to its form factor and the interface it uses to communicate with the computer. Its specifications should match both the slots and the interfaces available on your motherboard. Also, if you see an SSD being described as NVMe, do not assume that it is automatically using the M.2 form factor. Also, if you see an SSD described as being M.2, don't assume that it is using NVMe. Pay attention to its detailed specifications before deciding what to buy.
