Differenceswithenterpriseharddrives
Enterpriseharddrives:Asthenameimplies,enterpriseharddrivesareharddriveslaunchedforenterpriseapplications,combinedwithenterpriseItisnotdifficulttosummarizethecharacteristicsofenterprise-classharddiskswithhighperformance,highreliability,andhigherfaulttoleranceandsecurity.Mainlyusedinservers,storagediskarrays,graphicsworkstations,etc.
Desktop-levelharddrives:Mainlyaimedathomepersonalapplications,mainlyindesktopPCs,notebooksandotherfields.
Currently,enterprise-levelharddrivesmainlyuseSAS(SerialSCSI),FC(opticalfiber),SATAandotherinterfaces;desktop-levelharddrivesaremainlySATAinterfaces.
Differencesfromproducttechnicalspecifications
1.Capacity:Becauseenterprise-levelapplicationsrequirelargerstoragecapacity,enterprise-levelharddriveshavelargerstoragethandesktop-levelharddrives.Capacity,thecurrentmaximumcapacityofasingleharddiskcanreach10TB.
2.Performance:Mainlyreflectedinthespeed,cache,averageseektime,etc.Enterprise-levelharddriveshavearotationalspeedofmorethan10,000rpm,largercache(above4MB),shorterseektime,etc.
3.Reliability:Enterprise-levelharddriveshaveahighermeantimebetweenfailures.Generallyspeaking,theaveragetimebetweenfailuresofdesktop-gradeharddisksismostlyaround500,000hours,andtheaveragetimebetweenfailuresofenterprise-gradeharddisksismorethan1million.Themeantimebetweenfailurescannotreflectthequalityoftheharddisk,butonlyindicatestheprobabilityoftheharddiskfailure.
4.Applicationsuggestions:Ifitisreallyappliedinanenterpriseenvironment,suchas7*24hoursofuninterruptedwork,itisstronglyrecommendedthatyoupurchaseanenterprise-levelharddriveatthistime.Eveniftheperformancerequirementsarenothigh,userswhoplantouseSATAharddisksstronglyrecommendthatyouuseenterprise-levelharddisks.Becausethevalueofthedatayoustoreintheharddiskismuchhigherthanthevalueoftheharddisk.Oncetheharddiskfailsandthedataislost,Ithinkyouwillbeveryawareoftheloss.Therefore,themainreasonwhyenterprise-levelharddrivesarerecommendedhereisbecauseofreliabilityconsiderations.Afterall,desktop-gradeharddisksarenotdesignedfor7*24uninterruptedapplications,sotheircomponentsandtechnicalsolutionsarenotconsideredinthisregard.Therefore,oncedesktop-gradeharddisksareappliedtoenterprise-levelenvironments,theprobabilityofharddiskfailureswillbegreatlyenhanced..
