Microharddrives:Microharddrives

Inthenewerawherepeoplearepursuinglargecapacityandsmallvolume,neitherflashmemory(smallcapacity)nortraditionalharddisks(largevolume)canmeetmarketdemands.Themicroharddrivedevelopedfromthefieldofultra-smallnotebooksanddigitalcamerashasnaturallytakenthebatonofthetwooldpredecessors.

MostdevicesthatcanuseCFcardscandirectlyuseMicrodrive,suchasdigitalcameras,handheldcomputers,andMP3players.ThenotebookcomputeristransferredthroughthePCMCIAadapter.SincetheMicrodriveisslightlythickerthantheCFcard,thedevicemustcomplywiththeCFIIstandard.Thelarge-capacityMicrodrive(4GB)requiresthedevicetosupporttheFAT32filesystem.ComparedwithCF,thebiggestadvantageofMicrodriveisthelowerpriceperunitofstoragecapacity.Microdriveusesharddisktechnology,whichhasthecharacteristicsoflowcostandhighcapacity,andcanbecomeasubstituteforsolid-statestoragetechnologymemory.

Advantages

Largecapacity

Youshouldknowthatthediskareaof​​themicroharddiskisonly1inch,andtheoverallareaisonly1/3oftheareaof​​thephonecard,butthemainstreamcapacityhasreachedUptothe1-4GBlevel,and15GB(1inch)and60GB(1.8inch)productsareavailable,whetheritisusedforcamerashootingordatastorage,itismorethanenough.

Longservicelife

Itismadewithhighertechnologythantheharddisk,whichguaranteesitsservicelife.Itcanberepeatedlyerasedandwrittenmorethan300,000times,anditcanusuallyworkstablyforfiveyears.

Withcache

Thisisnotonlyfortheneedofshockabsorption,butalsoanimportantguaranteeforimprovingthedatatransmissionrate.Theshockabsorptioncanbedonebyexternalmemory,butIfthereisnocache,thespeedofthemicroharddiskwillappeartoberelativelyslow,andthegeneralproductisequippedwitha128KBcapacitydatacache.

Noneedforexternalpowersupply

Thepowerconsumptionofthemicroharddiskisverysmall,anditcanbeusedwhenconnectedtoUSB.Ifoneinterfaceisnotenoughpower,connectingtwointerfacesisdefinitelyOK,andtheharddiskisdirectlysolved.Thetroubleofaddingpowertothebox.Therefore,thefutureharddisktypeMP3maybeconnectedtothecomputerwithoutabattery.

High-speedtransmission

Themorepower-saving,smallersizemakespeopledoubtthedatatransmissionspeedofthemicroharddisk,buteveryonecanrestassuredthatthemicroharddiskhas3600-4200RPM(RotationPerMinute,rpm),thefastesthasreached4500RPM..Ofcourse,duetothesmallsizeofthedisk,thedatatransferrateislowerthanthatofordinaryharddisksatthesamespeed.Althoughthesmallsizeisnoteasytodissipateheat,theyallhaveanautomaticpowersavingmodethatcanactivelyreducetheheatgenerationandmakethehighspeedlonger.

Wideinterfacecompatibility

Likeordinaryharddisks,microharddisksarecompatiblewithavarietyofharddiskinterfacescompatiblewithindustrystandards.Thisismainlydeterminedbythecontrolchip,makingitsuitableforavarietyofHandhelddevice.Therefore,wewillseeCFcard,PCMCIA,USB2.0,ATAparallelportmicroharddisk,andtheremaybeATAserialportandSCSIinthefuture!

USB2.0high-speedexternaltransmission

Whenyouusethislarge-capacitymicroharddrivetostoresongs,pictures,videorecordings,applicationsoftwareandfiles,youwilldefinitelyexchangedatawithothers.Atthistime,afasttransmissionchannelisessential.USB2.0iscurrentlythemostcompatibleexternalinterfacestandard,whichcanachieveatransmissionspeedof480Mbps,whichisabout60MB/sec.AlthoughUSB1.1canbarelybeused,let'simaginethatwithsuchalarge-capacitydatastorage,thetransmissionflowwilldefinitelybelarge,sowetrytochoosethoseUSB2.0microharddiskMP3.

Highshockresistance

Duetothespecialdesignofthemicroharddisk,itsshockresistanceismuchstrongerthanordinarynotebookharddisks.Itsspecialmagneticheadloadingandunloadingtechnologymakestheimpactresistanceupto1500G(non-workingstate)and175G(workingstate).Evenifitisusedwithlow-endreadingequipment,thedualprotectionofthereaderandtheharddrivecanalsopreventtheharddrivefrominternalshocks.NotonlyasamicroharddiskMP3,itcanalsoprovidereliablestorageperformancefordigitalcameras,laptops,palmtopcomputers,GPSandotherportabledevices.

Precautions

Firstofall,becarefulnottoapproachmagneticmaterialsorstrongmagneticfields;storeanduseinanenvironmentabove-40℃orbelow65℃;bewareofbeingexposedtowaterorotherliquidsSoaking(Ifyouaccidentallygetwaterstains,youshouldwipeitdryassoonaspossible);preventthesurfacefrombeingsqueezedbyheavyobjectsorexternalforces;becarefulnottodropthegroundfromaheight;whennotinuseforalongtime,itshouldbeputbackintheplasticpackagingbox.

Inaddition,asthecapacityofthemicroharddiskbecomeslargerandlarger,youmustpayattentiontowhethertheproduct(digitalcamera)providesFAT32filesystemsupportwhenpurchasinga4GBmicroharddisk.MostoftheexistingdigitalcamerasuseFAT16inthememorycardfilesystem,andcanonlyrecognizeamaximumcapacityof2GB.Tousea4GBmicroharddrive,theproductmustsupportFAT32.

OnSeptember13,2007,SeagateTechnology,theworld’slargestharddrivemanufacturer,announcedinBeijingthatitsfourth-generationDB35,whichisusedbytheworld’smostdigitalvideorecorders(DVR)andhomemediacenters,Theseriesharddriveshavereachedacapacityof1TB(1000GB),whichisenoughtorecordupto200hoursofHDTVcontent.
