FireWire S3200 and USB 3.0 Specification Comparisons Before Release in 2008 FireWire S3200 un USB 3,0 Specifikācija Salīdzinājumi Pirms Release 2008
Recently we talked about Nesen mēs runāja par USB 3.0 standard USB 3,0 standarta that able to scale up to 4.8Gbps data transmission speed. , kas spēj samazināt līdz 4.8Gbps datu pārraides ātrumu. It is about ten times higher than current USB 2.0 standard in today PC market. Tas ir apmēram desmit reizes lielāks nekā pašlaik USB 2.0 standarta šodien PC tirgū. During the last IDF (Intel Developer Forum), Intel did disclose that the specification could be available in first half of 2008. Pēdējo IDF (Intel Developer Forum), Intel bija atklāt to, ka šīs specifikācija varētu būt pieejams pirmajā pusē, 2008. But now seems that the new FireWire S3200 standard, a main competitor for USB standard could get an earlier release by February 2008, before the availability of USB 3.0 specification. Bet tagad šķiet, ka jaunā FireWire S3200 standarta, galvenais konkurents USB standarta varētu iegūt agrāk atbrīvot gada februārī 2008, pirms pieejamību USB 3,0 specifikāciju. The FireWire S3200 is said to be able to achieve up to 3.2Gbps, make it closer to its competitor's data speed. The FireWire S3200, domājams, varētu sasniegt līdz 3.2Gbps, padarītu to tuvāku tās konkurenta datu ātrumu.
FireWire S3200 is the third version of IEEE 1394 proposed by the Trade Association. FireWire S3200 ir trešā versija, IEEE 1394, ko ierosināja tirdzniecības asociācija. The first version, FireWire 400 ran at 400Mbps while the second version, FireWire 800 at 800Mbps. Pirmais variants, FireWire 400 ilga pie 400Mbps bet otrā versija, FireWire 800 pie 800Mbps. This third version is getting much higher throughput even though they are based on same protocol and even physical connections. Šī trešā versija kļūst daudz lielāku caurlaides, pat ja tie pamatojas uz pašu protokolu un pat fizisko savienojumus. As compared to USB 3.0 that needs different optical fiber connectivity as mentioned Salīdzinājumā ar USB 3,0, ka vajadzības dažādos optisko šķiedru savienojumu, kā minēts here šeit in order to achieve gigabyte rate, FireWire S3200 has greater advantages of reusing existing cable and connectors based on its previous standard that could shorten development cycle as well as TTM (Time to market). , lai sasniegtu gigabaiti likmes, FireWire S3200 ir lielāka priekšrocības atkārtota esošo kabeļu un savienotāji, balstoties uz savu iepriekšējo standarta, kas varētu saīsināt izstrādes ciklu, kā arī TTM (laiks, lai tirgus). Besides, FireWire utilizes peer to peer architecture which is less CPU dependent as compared to USB in Master/Slave mode. Bez tam, FireWire izmanto peer to peer arhitektūra, kas ir mazāk CPU apgādībā, salīdzinot ar USB Master / Slave režīmā. Furthermore, FireWire can be extended to up to 100 meter while able to supply more power over USB port. Turklāt FireWire var pagarināt līdz 100 metrs savukārt var sniegt lielāku varu pār USB ports.
Regardless of so many pros and cons, nobody can predict if FireWire will able to take up more market segment (now dominant by USB 2.0) in few years down the road. Neskatoties uz tik daudz plusi un mīnusi, neviens nevar prognozēt, ja FireWire būs spējīga uzņemties vairāk tirgus segmentā (tagad dominējošais ar USB 2.0), kas dažus gadus nosaka ceļa. Even on the throughput delta, there is not much to say now on how much it will affect the actual device performance since the gigabyte rate usage is still under utilized. Pat to caurlaidspēja delta, nav daudz ko teikt, tagad par to, cik daudz tas iespaido faktiski ierīces darbību, jo gigabaita likme izmantošana joprojām tiek izmantoti.
