Filip Novotny Lub tuam txhab paub zoo Western Digital tau koom tes ntawm cov tuam txhab lag luam uas muab cov tsav sab nraud nrog Thunderbolt kev txhawb nqa. Tus tshiab VelociRaptor Duo siv lub ntiaj teb cov discs ceev tshaj plaws thiab qhov txuas ceev tshaj plaws nyob rau tib lub sijhawm. Kev sib txuas zoo li cas hauv kev xyaum?
Tsis ntev los no, cov tuam txhab lag luam hauv computer, coj los ntawm Apple, tau txav deb ntawm kev siv cov hard drive classic hauv kev pom zoo ntawm SSDs sai dua. Txawm li cas los xij, flash thev naus laus zis tseem kim heev, uas yog vim li cas lub peev xwm khaws cia ntawm cov laptops feem ntau yog nyob ib puag ncig 128-256 GB, nrog rau cov qauv kim tshaj plaws muaj qhov siab tshaj plaws ntawm 512-768 GB. Feem ntau cov kws tshaj lij uas ua haujlwm nrog cov ntaub ntawv audiovisual loj yuav pom zoo tias cov peev txheej zoo li no tsis txaus rau lawv txoj haujlwm. Txawm li cas los xij, txawm tias ntau tus neeg siv zoo tib yam yuav pom sai sai tias lawv cov yeeb yaj kiab thiab suab paj nruag tsis haum rau hauv disk sab hauv. Tom qab ib lub sij hawm uas lub peev xwm ntawm hard drives khaws cia thiab loj hlob, peb tam sim no rov qab mus rau lub sij hawm uas nws yog feem ntau tsim nyog los daws cov kev cia ntawm cov ntaub ntawv loj dua sab nraud.
Rau cov tib neeg zoo tib yam, pheej yig hard drives, uas muaj ntau nyob rau hauv kev ua lag luam, tej zaum yuav txaus raws li ib tug dlej kev daws teeb meem, tab sis ntau xav tau cov neeg siv thiab cov tub txawg yuav tsis txaus siab rau qhov kev daws teeb meem no. Cov disks pheej yig dua no feem ntau tuaj yeem tsim qhov nrawm ntawm 5400 kiv puag ncig ib feeb xwb. Tej zaum qhov teeb meem loj dua yog lawv qhov sib txuas qeeb qeeb. Qhov kev sib txuas ntawm USB 2 feem ntau tuaj yeem hloov pauv tsuas yog 60 MB ib ob. Rau qhov tsis siv ntau lwm los ntawm Apple, FireWire 800, nws yog 100 MB ib ob. Yog li ntawd, txawm tias cov neeg tsim khoom siv cov disks sai dua ntawm tsawg kawg 7200 kiv puag ncig, lub connector tseem yuav tshwm sim raws li "bottleneck" - qhov txuas tsis muaj zog uas ua rau tag nrho cov kab ke.
Qhov tsis muaj zog no yuav tsum raug tshem tawm los ntawm tiam thib peb ntawm USB txuas nrog rau Thunderbolt, qhov tshwm sim ntawm kev koom tes ntawm Apple thiab Intel. USB 3.0 yuav tsum tau theoretically hloov tau 640 MB ib ob, Thunderbolt ces mus txog 2,5 GB ib ob. Ob qho kev daws teeb meem yuav tsum yog qhov txaus txaus rau niaj hnub no SSD drives, qhov ceev tshaj plaws hnub no yog nyob ib ncig ntawm 550 MB / s. Manufacturers xws li LaCie, iOmega los yog Kingston, tom qab lub sijhawm luv luv pib muab cov SSD sab nraud, uas, txawm li cas los xij, qhia tib yam teeb meem nrog SSDs sab hauv, uas yog ib feem ntawm ntau phau ntawv niaj hnub no. Yog tsis muaj kev nqis peev tseem ceeb lossis kev tsis sib haum xeeb, nws tsis tuaj yeem ua tiav qhov peev txheej loj uas yuav tsum tau ua, hais tias, lub tsev qiv ntawv loj ntawm Aperture lossis HD video rau kev ua tiav hauv Final Cut Pro.
Western Digital coj txoj kev sib txawv me ntsis. Nws coj ob lub zog ceev ceev ceev, muab tso rau hauv lub chassis dub zoo, thiab muab ob lub Thunderbolt chaw nres nkoj rau tom qab. Qhov tshwm sim yog qhov chaw cia sab nraud uas yuav tsum sib txuas ua ke muaj peev xwm, nrawm thiab pheej yig hauv chav kawm - WD Kuv Phau Ntawv VelociRaptor Duo.
Cia peb saib ua ntej yuav ua li cas lub tsav nws tus kheej tsim. Sab nrauv zoo li classic Western Digital sab nraud tsav, nws yog lub thawv yas dub uas tsuas yog dav me ntsis vim yog siv ob lub hard drive. Muaj tsuas yog ib qho me me LED nyob rau pem hauv ntej uas ua raws li lub hwj chim rau thiab qhov taw qhia ua haujlwm. Hauv qab no, lub logo WD ci ntsa iab zoo siab. Nyob rau sab nraum qab peb pom lub qhov (socket) txuas, ob lub Thunderbolt ports thiab kev ruaj ntseg Kingston xauv. Los ntawm qhov qhib sab saum toj, peb tuaj yeem tshawb xyuas qhov sab hauv ntawm lub disc.
Nkaum muaj ob lub hard drives los ntawm lub siab tshaj plaws WD series. Cov no yog ob lub terabyte VelociRaptor tsav. Los ntawm lub Hoobkas, lawv tau formatted rau classic Mac HFS +, yog li nws muaj peev xwm pib siv tam sim ntawd. Los ntawm lub neej ntawd, cov tsav tau teeb tsa ua RAID0, yog li lawv yog software-txuas thiab ntxiv rau qhov chaw cia ntawm 2 TB. Los ntawm ib daim ntawv thov tshwj xeeb (lossis cov khoom siv hauv Disk Utility), tom qab ntawd lub disk tuaj yeem hloov mus rau RAID1 hom. Nyob rau hauv tas li ntawd, lub peev xwm yuav halved thiab lub thib ob disk yuav ua raws li ib tug thaub qab. Ua tsaug rau ob qhov chaw nres nkoj Thunderbolt, tom qab ntawd nws tuaj yeem txuas ob peb VelociRaptor tsav hauv kab thiab siv RAID ntau dua. Vim yog qhov xwm txheej ntawm Thunderbolt, peb tuaj yeem txuas tau yooj yim txhua yam khoom siv uas muaj qhov txuas hauv txoj kev no. Nws yog vim li no, piv txwv li, txuas ib lub VelociRaptor tsav mus rau MacBook Pro, lwm qhov rau nws, thiab thaum kawg Thunderbolt Zaub rau qhov ntawd.
Los ntawm kev qhib sab saum toj, cov discs tuaj yeem yooj yim tshem tawm thiab hloov pauv yam tsis tas siv lub hau ntswj. Txawm hais tias classic SATA kev twb kev txuas yog muab zais rau hauv qab ntawm lub thawv, koj twv yuav raug hu yuav tsis xav siv tej drives uas tsis yog lub VelociRaptors muab los ntawm cov khw. Koj yuav tsis pom dab tsi zoo dua tam sim no, qhov ceev ntawm 10 kiv puag ncig ib feeb tsuas yog muab los ntawm cov kab saum toj kawg nkaus ntawm Western Digital. Tsis tas li ntawd, cov disks siv tau muaj lub cim xeeb loj ntawm 000 MB thiab tau tsim los rau kev xa mus tas li.
Raws li daim ntawv qhia tshwj xeeb, VelociRaptor Duo zoo li pheej hmoo heev, tab sis nws yuav yog qhov tseem ceeb dua li nws ua tau raws li kev thauj khoom tiag tiag. Ib qho tseem ceeb tshaj plaws rau kev xaiv tsav yog undoubtedly nws ceev, uas yog vim li cas peb sim nws kom huv si peb tus kheej. Siv ob peb daim ntawv thov tshwj xeeb, peb tau mus txog qhov nrawm ntawm 1 MB / s rau kev nyeem ntawv thiab sau ntawv thaum hloov cov ntaub ntawv loj (16-360 GB). Rau cov ntaub ntawv me me, qhov ceev no tuaj yeem poob qis dua 150 MB / s, uas yuav tsum tau cia siab vim qhov xwm txheej ntawm hard drives. Tag nrho cov hard drives, txawm tias lawv siab npaum li cas, ib txwm tiv tau zoo dua nrog cov ntaub ntawv loj dua, vim qhov feem ntau qis dua. Tom qab tag nrho, hauv kev ua haujlwm nrog cov ntaub ntawv me me, VelociRaptor ua tiav kwv yees li cov txiaj ntsig zoo ib yam li cov khoom lag luam sib tw LaCie, Kev cog lus los yog Elgato.
Piv nrog rau cov neeg sib tw no, txawm li cas los xij, nws ua tau zoo heev. Kev daws teeb meem los ntawm lub tuam txhab Elgato nce mus txog qhov ceev ntawm 260 MB / s, LaCie Qhov nruab nrab ntawm 200-330 MB / s ntau Pegasus los ntawm tuam txhab Kev cog lus tom qab ntawd nws nce mus txog qhov nrawm dua 400 MB / s, tab sis ntawm tus nqi siab dua.
Xyaum hais lus, VelociRaptor Duo tuaj yeem nyeem lossis sau 700MB CD hauv ob vib nas this, dual-txheej DVD hauv 20 vib nas this, thiab ib txheej Blu-duab tshav hauv ib feeb thiab ib lub hlis twg. Txawm li cas los xij, nws tseem yuav tsum tau coj mus rau hauv tus account qhov ceev ntawm qhov nruab nrab thib ob. Yog hais tias peb siv qeeb hard drives nyob rau hauv, hais, ib tug MacBook Pro, peb yuav to taub tsis tau mus txog qhov siab tshaj plaws VelociRaptor. Ua ntej yuav, nws yog qhov zoo tshaj plaws los siv, piv txwv li, daim ntawv thov pub dawb BlackMagic, uas yuav pab peb txiav txim siab ceev ntawm disk ntawm peb lub computer. Txhawm rau muab lub tswv yim rau koj - nrog MacBook Air 2011 nrog Toshiba tsav nrawm dua, peb tau mus txog 242 MB / s, yog li peb tsuas yog siv lub peev xwm ntawm thunderbolt tsav mus rau qhov txwv. Nyob rau hauv sib piv, xyoo no tiam ntawm Cua twb mus txog speeds ntawm tshaj 360 MB / s, yog li nws yuav tsis muaj teeb meem nrog VelociRaptor.
Tag nrho hauv tag nrho, VelociRaptor Duo yog ib qho kev daws teeb meem zoo rau cov uas tab tom nrhiav loj sab nraud cia siv nrog Thunderbolt-based Macs lossis PCs tshiab. Qhov zoo tshaj plaws, nws yog qhov tsim nyog rau thaub qab lossis txuag cov ntaub ntawv ua haujlwm. Cov kws tshaj lij tshwj xeeb yuav tau txais txiaj ntsig los ntawm kev hloov pauv ceev heev, uas lawv tsis tau npau suav nrog USB 2.0. Lwm qhov ntxiv yog lub neej ua haujlwm ntev, uas SSDs tsis tuaj yeem muab. Thaum ua haujlwm nrog cov ntawv thov duab, cov ntaub ntawv tau sau ntau zaus, uas cuam tshuam rau flash drives.
Leej twg yuav tsis no disc yuav haum rau? Ua ntej, rau cov neeg siv uas feem ntau ua haujlwm nrog ntau cov ntaub ntawv me me thiab xav tau kev ua haujlwm siab tshaj plaws. Nyob rau hauv tas li ntawd, txhua lub hard disk tsis tuaj yeem muab kev nrawm dua li kaum tawm megabytes ib ob, thiab qhov kev daws teeb meem nkaus xwb yuav yog SSD kim. Thib ob, rau cov neeg siv xav tau heev uas xav tau ntau qhov chaw lossis xav tau ntau dua RAID teeb tsa. Qee tus kuj yuav tsis txaus siab rau qhov tsis muaj lwm yam kev sib txuas tshwj tsis yog Thunderbolt. Tab sis rau txhua tus neeg, WD Kuv Phau Ntawv VelociRaptor Duo tsuas yog pom zoo. Txawm tias nws lub taub hau-kos npe. Koj tuaj yeem pom nws hauv Czech khw ntawm tus nqi ntawm ib ncig ntawm 19 CZK.

Peb xav ua tsaug rau Czech tus neeg sawv cev chaw ua haujlwm ntawm Western Digital rau qhov qiv ntawm VelociRaptor Duo disc
Lawv yog undoubtedly tsis tus ceev tshaj discs nyob rau hauv lub ntiaj teb no ... 15k rpm FC discs txawv kiag li, ntawm chav kawm, nyob rau hauv cov nqe lus ntawm tus nqi thiab lub hom phiaj ntawm kev siv, tab sis qhov ntawd tsis hloov qhov tseeb ;-)
Hauv kev tshuaj xyuas, nws tau hais raws li tus nqi rho tawm, uas tsis tshwm sim nyob qhov twg hauv tsab xov xwm. Ummm #fail
Ib tug npoj yaig tsis nco qab :-) Ntxiv.
Thiab poob # 2 - muaj Thunderbolt, yog li vim li cas thiaj yuav tsum muaj USB 3.0? :D
Piv txwv ntawm lub neej: Lub MacBook tawg, ib tus neeg siv nws los kho thiab muaj kev hloov pauv qub. Tab sis koj nkag tsis tau cov ntaub ntawv tsis muaj USB... Ntau txoj kev sib txuas yog ib txwm zoo dua.
Yog, kuv tsis tau xav txog qhov ntawd… :)
Yog, kuv tsis tau xav txog qhov ntawd… :)
Thiab tsis muaj lub adapter los ntawm Thunderbolt rau USB los ntawm lub caij nyoog?..
Yog hais tias, piv txwv li, ib tug npoj yaig los ntawm lub qhov rais laptop xav upload ib feem ntawm nws ua hauj lwm rau ib tug disk, koj yuav tsis muaj hmoo.
teb hauv qab no… :)
teb hauv qab no… :)
Yog hais tias ib tug npoj yaig los ntawm lub qhov rais laptop xav sau ib yam dab tsi rau kuv Velociraptor disks hauv HFS +, tej zaum nws yuav tsis tau deb :D
Nws tsis paub meej tias qhov kev qhia ceev yog nyob rau hauv Raid 0 lossis Raid 1, Cov Lus Cog Tseg Pegasus ua tiav qhov nrawm dua vim qhov tseeb tias nws muaj ntau hom kev sib hloov disks txuas nrog hauv raid 0. Hauv Raid 0, ntau disks, qhov siab dua. . Yog tias kuv ntsaws rau hauv ntau WD Thunderbolt drives thiab formatted lawv mus tua 0, kuv yuav ua tau zoo sib xws speeds raws li tau cog lus tseg. Elgato, ntawm qhov tod tes, siv ib qho qeeb ssd disk, yog li cov khoom no tsis tuaj yeem muab piv rau txhua qhov.
Tus kheej, kuv xav tias qhov no raptor yog overpriced, vim hais tias nws muaj classic (txawm hais tias high-speed) discs uas tsis ua miraculously ntawm lawv tus kheej. Classic WD Thunderbolt Duo yog ib nrab ntawm tus nqi thiab tsuas yog kwv yees li 20% qeeb ntawm kev ua haujlwm. Yog kuv yuav 2 leeg thiab koom nrog lawv sib koom ua ke, kuv yuav tau txais kev nrawm dua rau tib tus nqi. Tsis tas li ntawd, tus nqi ntawm tus raptor no tsis txawv ntau ntawm qhov pheej yig tshaj cog lus pegasus, uas muaj 4 disks thiab nce mus txog qhov nrawm ntawm 450MB / s.
Kuv kuj xav tshuaj xyuas cov disc ib yam nkaus, tshwj xeeb yog tias kuv muaj ib qho seem tom qab ntawd ...
tsis muaj usb3? thiab yog thunderbolt puas muaj???
Kuv muaj, thiab kuv txaus siab heev, ua ke ntawm Macbook Pro nrog i7, Kuv siv nws ua ib qho thaub qab disk rau TM thiab rau ib ntus thaub qab ntawm kev faib ua haujlwm.
