Waxaan dhawaan ka soo iibsaday qalab NAS ah (keydka ku xiran shabakada) Synology , waxay ku xirtay shabakadayda waxaanan bilaabay wareejinta faylasha. Waxa ugu horreeya ee aan ogaaday waxay ahayd sida uu u gaabis u yahay xawaaraha wareejinta shabakadu.

Waxaan ku koobiyaynayay qaar ka mid ah faylalka fiidyaha ee waaweyn waxayna qaadanaysay weligeed! Waxaan go'aansaday inaan eego xawaaraha kala wareejinta ee u dhexeeya NAS iyo PC si aan u arko heerka wareejinta xogta.

Waxaan soo dejiyey barnaamij la yiraahdo LAN Speed ​​Test , kaas oo helay dib u eegis aad u fiican, oo aan isku dayay. Hubaal ku filan, xawaarahayga soo dejinta wuxuu ka yaraa 40 MB/s! Ogow taasi waa megabytes ilbiriqsikii, ma aha megabits ilbiriqsikii. Waxaan si faahfaahsan uga hadli doonaa Mbps vs MBps iyo dhammaan waxyaalahaas farsamada.

Ka dib markii aan sameeyay xoogaa cilmi baaris ah, waxaan ogaaday waxa aan samaynayo khalad waxaana ugu dambeyntii helay heerka wareejinta ilaa 85 MB/s oo aad u xawli badan iyo 110 MB/s soo dejisan! Farsamo ahaan, waxaad heli kartaa oo keliya xawaarahaas haddii aad isticmaalayso Gigabit Ethernet .

Haddii aad haysato 10 Gigabit Ethernet , markaa waxaad aragti ahaan aad helaysaa xawli 10 jeer degdeg ah oo la soo dejiyo. Hoos ayaan ku sharxi doonaa wax badan oo ku saabsan taas.

Cutubyada Qiimaha Xogta LAN

Marka hore, aynu si cad u qeexno tirooyinka. Waxaa jira halbeegga 100 Mbps ethernet, kaas oo ah waxa dadka intooda badan ay ku haystaan ​​guriga. 100 Mbps waa 100 megabits ilbiriqsikii. Taas waxa loo turjumay 12.5 megabytes ilbiriqsikii ( MBps or MB/s ). Aad ayey u fududahay in loo beddelo MB^(MBs) -yada maadaama taasi ay tahay wax aan dhammaanteen naqaanno halkii aan ka ahayn xoogaa yar.

Tani waxay ka dhigan tahay in haddii aadan haysan gigabit router ama kaarka shabakadda gigabit ee kumbuyuutarkaaga ama NAS , xawaaraha ugu badan ee aad ku wareejin karto faylka shabakada gurigaaga waa 12.5 MBps .

Sidoo kale, adduunka dhabta ah, macquul maaha in dhab ahaantii la helo aragtida ugu badan. Waxay u badan tahay inaad ku dambayn doonto meel ku dhow 4 ilaa 8 MBps . Haddii aad helayso wax aad u hooseeya sida 1 MBps ama ka yar, waxaa jira sababo taas aan hoos ku xusi doono.

Ogsoonow in xitaa haddii kombuyuutarku leeyahay kaarka gigabit ethernet, ma heli doontid xawaarahaas xawaaladaha sarreeya ilaa dhammaan aaladaha xogta lagu kala qaado iyada oo loo marayo taageerada gigabit.

Haddii aad ku haysato kaarka gigabit ethernet kombuyuutarkaaga, routerkaaga ama furahaagu waa gigabit sidoo kale qalabka helaya wuxuu leeyahay kaarka gigabit ethernet, xawaarahaaga xawaaluhu wuxuu ku boodaa mid aad u wanaagsan 1000 Mbps ama 125 MBps (125 megabytes per second).

Mar labaad, ma heli doontid xawaaraha aragtidaas, laakiin waa inaad meel kasta ka helaysaa 70 ilaa 115 MBps iyadoo ku xidhan nooca faylalka aad wareejinayso iyo dejinta shabakaddaada.

Ugu dambeyntii, aaladaha ugu dambeeyay ayaa lagu cusboonaysiin karaa kaararka shabakadda 10GBe. Waxaad, dabcan, u baahan doontaa shixnad sidoo kale xamili kara 10GBe, laakiin sida aad ka arki karto shaxda, xawaaruhu waxa uu 10 jeer ka dheereeyaa waxa ay dadka badankiisu hadda isticmaalaan.

Haddii aad ku shaqaynayso tiro badan oo faylal muuqaal ah oo u baahan in lagu wareejiyo shabakada, cusboonaysiinta qalabkaaga ayaa si weyn u wanaajin doonta socodkaaga shaqada. Nasiib wanaag, fiilada Cat5e waxay xamili kartaa 10GBe masaafo gaaban. Haddii aad u baahan tahay inaad dejiso fiilooyinka cusub, waa inay noqotaa Cat 6a ama Cat 7 .

Xawaaraha wareejintu wuxuu ku xidhan yahay maxaa?

Markaa sidaan kor ku soo sheegnay, xawaaraha wareejinta shabakadu wuxuu ku xidhan yahay nooca ethernet ee aad ku leedahay shabakadaada, laakiin taasi maaha qodobka kaliya. Waxaa jira dhowr arrimood oo kale oo go'aamiya xawaarahaaga wareejinta ugu dambeeya ee labada aaladood.

Xawaaraha Hard Drive-ka

Hal arrin oo weyn oo xaddidaysa waa xawaaraha darawalka adag. Haddii aad leedahay kombuyuutar leh 5400 RPM , heerka wareejintaadu aad ayuu uga gaabin doonaa haddii aad haysato laba SSD drives oo ku jira qaabaynta RAID 0 ! Sidee sidaas tahay? Waa hagaag, waxay kuxirantahay.

Shabakaddayda, xitaa gigabit ethernet, kaliya waxaan helaa qiyaastii 40 ilaa 50 MB/s marka la isticmaalayo saxan adag oo dhaqameed.

Haddii aad internetka wax ku akhrido, waxa aad ogaan doontaa in xataa inta ugu badan ee Hard Drive-yada ( SATA 3.0 GB/s ) ay ku badnaan doonaan xawaaraha akhriska ee 75 MB/s . Taas macnaheedu waa inaadan xitaa awoodin inaad dhaafto taas adigoon aadin qaabaynta qaaliga ah sida RAID 0,1 , ama 5 oo leh kontaroolayaasha ^{(RAID 0,1)}RAID hardware ee dhabta ah .

Markaad kor ugu booddo SSD , markaa arrimuhu aad bay u degdegayaan. Si kastaba ha noqotee, si aad u hesho natiijooyinkii aan ku tusay xagga sare (oo ku dhow 110 MB/s ), waxay u badan tahay inaad u baahan tahay inaad haysato darawal NVMe SSD aad u degdeg badan . Dareewaladani waxay akhrin karaan oo qori karaan ilaa 3000 MB/s , taas oo aad uga fog Gigabit Ethernet .

Xawaaraha baska

Xitaa haddii aad haysato darawal adag oo degdeg ah, xogta ayaa weli ah inay ka soo wareejiso darawalka adag una wareejiso Motherboard-kaaga kadibna kaarka shabakadda. Xawaaraha baska wuxuu sameeyaa farqi weyn.

Tusaale ahaan, haddii aad isticmaalayso baska PCI da'da weyn , heerka wareejinta xogtu waa 133 MB/s . Taasi waxay u muuqan kartaa inay ka sarreyso heerka ugu sarreeya ee gigabit ethernet waana waa, laakiin baska waa la wadaagaa nidaamka oo dhan, markaa marnaba run ahaantii ma helin xawaarahaas.

Nooca ugu dambeeya ee PCI Express wuxuu ku heli doonaa ugu badnaan 985 MB/s , markaas taasi waxay samaynaysaa farqi weyn. Tani waxay asal ahaan ka dhigan tahay haddii aad isku dayeyso inaad ka wareejiso faylasha kombuyuutar dhab ah iyo xitaa haddii aad iibsato kaarka gigabit ethernet, ha filanin inaad meel u dhow u dhow 125 MB/s xawaaladaha.

Xargaha Shabakadda

Dhinaca kale ee waxaas oo dhan waa fiilooyinka. Haddii fiilooyinkaagu ay duug yihiin ama haddii ay ku dhow yihiin ilaha korontada, waxay saameyn kartaa waxqabadka. Sidoo kale, dhererku wuxuu sameyn doonaa isbeddel haddii fiilooyinka ay aad u dheer yihiin.

Guud ahaan, si kastaba ha ahaatee, tani ma samaynayso farqi weyn, markaa ha bixin oo ha bilaabin inaad beddesho dhammaan fiilooyinkaaga. Asal ahaan waxaad rabtaa inaad hubiso inaad haysato fiilooyinka CAT 5e ama CAT 6a/7 .

Qodobka ugu weyn ee laga heli karo halkan ayaa ah in darawalka adag uu yahay arrin xaddidan oo weyn waana sababta ugu badan ee aad arki doonto kaliya natiijooyinka u dhexeeya 30 ilaa 80 MB/s . Si aad u hesho tirooyin aad u sarreeya, waxaad u baahan doontaa RAID 0 ee darawallada adag ee dhaqameed, NVMe ee SSDs ama 10GBe aaladaha.

Qalabka Shabakadda

Ugu dambayntii, waa in aad isku daydaa in aad labadaada mishiin ( NAS iyo PC) ku xidhaan furaha ama router isku mid ah. Waxaan ku xiraa kombuyutarkayga iyo NAS isla beddelka ka dibna waxaan ku xidhaa furahayga router-ka wireless-ka.

Inta badan router-yada sidoo kale waa furayaasha iyo farsamo ahaan waa inaad heshaa xawaare la mid ah kan beddelka go'an. Si kastaba ha noqotee, waayo-aragnimadayda, beddelka u go'an ee Netgear ama Cisco had iyo jeer waxay u egtahay inay ka fiicnaato router-ka wireless-ka ee leh dekedo ku-yaalla.

Marka labaad, ma heli doontid xawaare aad u dheereeya haddii aad wifi ku xirayso^(WiFi) PC-gaaga ama laptop-kaaga. Waa inaad hubisaa inaad isticmaalayso dekedda Ethernet si aad u hesho xawaaraha ugu dhakhsaha badan ee suurtogalka ah.

Cabbirka faylka

Waxa kale oo aan ogaaday in wareejinta tan galalka yaryar ay ka gaabinayso wareejinta faylal ka yar oo waaweyn. Tusaale ahaan, markaan ku wareejinayo kumanaan sawiro oo farabadan, waxaan heli lahaa ku dhawaad ​​​​20 ilaa 60 MB/s heerka wareejinta halka wareejinta faylalka filimada waaweyn dhowr GB^(GBs) oo cabbirkoodu ay soo saari doonaan 100 MB/s+ dhakhso leh .

Gabagabo

Waxaan rajeyneynaa in boostadani ay ku siineyso faham wanaagsan oo ku saabsan waxa saameeya xawaaraha wareejinta shabakadda ee LAN kaaga . Tani waligeed runtii arin aan dan ka lahaa wax badan ka hor ma ahayn, laakiin ka dib markii aan helay kamarad fiidiyoow ah oo 4K ah, waxaa la igu qasbay inaan iibsado NAS si aan u maareeyo dhammaan xogtaas dheeraadka ah.

Heerarka wareejinta ee runtii gaabiska ah ayaa iga dhigay inaan falanqeeyo shabakadayda wax badan ayaan ka bartay intii aan jidka ku jiray. Xitaa haddii aanad wax badan ka danayn xawaarahaaga wareejinta hadda, waxaa jiri kara wakhti mustaqbalka ay si lama filaan ah isbeddel weyn u samayn doonto.

Noo sheeg fikradahaaga faallooyinka. Xawaare noocee ah ayaad ku heleysaa LAN -kaaga ? Ku raaxayso!

Understanding LAN Network Data Transfer Speeds

I recently bought a NAS (network attached storage) device from Synоlogy, connected it up to my netwоrk and started transferring files. The first thing І noticed was how slow the network transfer speed was.

I was copying over some large video files and it was taking forever! I decided to check the transfer speed between my NAS and PC to see the rate of the data transfer.

I downloaded a program called LAN Speed Test, which had gotten some excellent reviews, and tried it out. Sure enough, my download speed was less than 40 MB/s! Note that is megabytes per second, not megabits per second. I’ll go into more detail on Mbps vs MBps and all that technical stuff.

After doing some research, I figured out what I was doing wrong and eventually got the transfer rate up to a super speedy 85 MB/s upload and 110 MB/s download! Technically, you can only get that speed if you’re using Gigabit Ethernet.

If you have 10 Gigabit Ethernet, then you could theoretically be getting a whopping 10 times faster upload and download speed. I’ll explain more about that below too.

LAN Data Rate Units

First, let’s get the numbers clear. There is standard 100 Mbps ethernet, which is what most people have at home. 100 Mbps is 100 megabits per second. That is translated into 12.5 megabytes per second (MBps or MB/s). It’s much easier to convert to MBs since that is something we are all familiar with rather than bits.

This means that if you don’t have a gigabit router or switch and gigabit network card on your computers or NAS, the maximum speed you’ll be able to transfer a file across your home network is 12.5 MBps.

Also, in the real world, it’s impossible to actually get that theoretical maximum. You’ll probably end up somewhere around 4 to 8 MBps. If you are getting something really low like 1 MBps or less, there are reasons for that which I will mention below.

Note that even if your computer has a gigabit ethernet card, you won’t get those higher transfer speeds unless all the devices that the data is being transmitted through support gigabit.

If you have a gigabit ethernet card on your computer, your router or switch is gigabit and the receiving device also has a gigabit ethernet card, your max transfer speed jumps to a much better 1000 Mbps or 125 MBps (125 megabytes per second).

Again, you won’t get that theoretical speed, but you should be getting anywhere from 70 to 115 MBps depending on the type of files you are transferring and your network setup.

Finally, the latest devices are upgradeable with 10GBe network cards. You’ll, of course, need a switch that can also handle 10GBe, but as you can see from the chart, the transfer speed is 10 times faster than what most people use right now.

If you’re working with a ton of video files that need to be transferred over the network, upgrading your hardware will greatly improve your workflow. Luckily, Cat5e cable can handle 10GBe over shorter distances. If you need to lay down new cabling, it should be Cat 6a or Cat 7.

Transfer Speed Depends on What?

So as we mentioned above, network transfer speed depends on the type of ethernet you have on your network, but that’s not the only factor. There are several other factors that determine your final transfer speed between two devices.

Hard Drive Speed

One major limiting factor is the hard drive speed. If you have a computer with a 5400 RPM, your transfer rate will be a lot slower than if you have two SSD drives in a RAID 0 configuration! How so? Well, it depends.

On my network, even with gigabit ethernet, I only get around 40 to 50 MB/s when using a traditional platter hard drive.

If you read online, you’ll find that even most hard drives (SATA 3.0 GB/s) will max out at a read speed of 75 MB/s. That means you won’t even be able to past that without going to more expensive configurations like RAID 0,1, or 5 with actual hardware RAID controllers.

When you jump up to an SSD, then things will get faster. However, to get the results I showed you at the top (close to 110 MB/s), you most likely need to have a super-fast NVMe SSD drive. These drives can read and write up to 3000 MB/s, which is well beyond Gigabit Ethernet.

Bus Speed

Even if you have a fast hard drive, the data still has to transfer from the hard drive to your motherboard and then to the network card. The bus speed makes a big difference.

For example, if you are using an older PCI bus, the data transfer rate is only 133 MB/s. That may sound higher than the maximum for gigabit ethernet and it is, but the bus is shared across the whole system, so you never really get that speed.

The latest PCI Express version will get you a max of 985 MB/s, so that makes a huge difference. This basically means if you’re trying to transfer files from a really old computer and even if you buy a gigabit ethernet card, don’t expect to be getting anywhere near the max 125 MB/s transfer rate.

Network Cables

Another aspect to all of this is the cabling. If your cables are old or if they are close to power sources, it could affect performance. Also, the length will make a difference if the cables are very long.

Overall, however, this is not going to make huge difference, so don’t go out and start replacing all your cables. You basically want to make sure you have CAT 5e or CAT 6a/7 cables.

The major point to get from here is that the hard drive is a major limiting factor and is the most likely reason you will only see results range from 30 to 80 MB/s. To get really high numbers, you’ll need RAID 0 for traditional hard drives, NVMe for SSDs or 10GBe devices.

Network Devices

Lastly, you should try to keep your two machines (NAS and PC) connected to the same switch or router. I plug my computer and NAS into the same switch and then connect my switch to the wireless router.

Most routers are also switches and technically you should get the same speeds as a dedicated switch. However, in my experience, a dedicated switch from Netgear or Cisco always tends to perform better than a wireless router that has built-in ports.

Secondly, you won’t get fast speeds if you are connecting via WiFi from your PC or laptop. You have to make sure you are using the Ethernet port to get the fastest speed possible.

File Size

I have also noticed that transferring a ton of small files is slower than transferring fewer larger files. For example, when transferring thousands of photos in a bunch of directories, I would get around 20 to 60 MB/s transfer rate whereas transferring large movie files several GBs in size would yield a faster 100 MB/s+.

Conclusion

Hopefully this post gives you a better understanding of what affects the network transfer speed on your LAN. This was never really an issue I cared about much before, but after I got an 4K video camera, I was forced to buy a NAS in order to manage all that extra data.

The really slow transfer rates got me analyzing my network and I learned a lot along the way. Even if you don’t care much about your transfer speeds right now, there may be a time in the future where it will suddenly make a big difference.

Let us know your thoughts in the comments. What kind of speed do you get on your LAN? Enjoy!
