Pakupera kwesvondo rapfuura Western Digital mukupindura kuratidzwa kwekushandiswa kusina kunyorwa kweSMR (Shingled Magnetic Media Recording) tekinoroji mumadhiraivha eWD Red NAS ane huwandu hwe2 TB uye 6 TB. Toshiba uye Seagate Mabhuroka & Mafaira sosi ayo mamwe madhiraivha avo anoshandisawo isina kunyorwa SMR tekinoroji. Ndinofunga yave nguva yekuti vatengesi vePC vachenese zvinhu.
Iyo SMR tiled magineti yekurekodha nzira inoita kuti zvikwanisike kuwedzera simba rekuchengetedza ne15-20%. Nekudaro, tekinoroji ine zvipingamupinyi zvakakosha, kiyi yacho kuderera kwekumhanya kwekunyorazve data, iyo inogona kuve yakakosha kana ichishandiswa muPC.
Naizvozvo, vagadziri vedesktop uye malaptop vanofanirwa kuratidza zvakajeka mune zvinyorwa zvehunyanzvi uye zvekushambadzira zvinhu izvo masisitimu avo anoshandisa madhiraivha ane SMR tekinoroji. Izvi zvinodzivirira mamwe maWD Red NAS madhiraivha kubva kuitika muvatengi maPC.
Mukuru weindasitiri sosi, aida kuramba asingazivikanwe, akaudza Blocks & Files kuti: "Hazvishamisi kuti WD neSeagate vaipa SMR desktop hard drives kumaOEMs - mushure mezvose, iwo akachipa pachiyero. Uye zvinosuruvarisa, hazvishamisi kuti vagadziri vedesktop vakaita saDell neHP vakashandisa mumashini avo pasina kuudza vatengi vavo uye vashandisi vekupedzisira (uye / kana bhizinesi PC vatengi, kazhinji vanotenga vamiririri)... Ndinofunga kuti dambudziko riri kutopararira mukati mekupa. cheni uye haina kungogumira kune vanogadzira hard drive. "
WD inoshandisa SMR muRed series madhiraivha ane masimba e1, 2, 3, 4 uye 6 TB, uye akajairwa CMR kurekodha mu8, 10, 12 uye 14 TB madhiraivha emhuri imwe chete. Ndiko kuti, tiri kutaura nezvekuparadzanisa mhuri imwe yezvigadzirwa muzvikamu zviviri, chimwe nechimwe chinoshandisa zvakasiyana disk rekodhi tekinoroji. Uyezve, SMR inoshandiswa kuwedzera kudzikisa mutengo wemhinduro dzinodhura.
WD mukutaura kwayo yakataura kuti pakuedza WD Red madhiraivha, haina kuwana chero matambudziko neRAID kuvaka patsva nekuda kweiyo SMR tekinoroji. Nekudaro, vashandisi veReddit, Synology uye smartmontools maforamu vakawana matambudziko: semuenzaniso, neZFS RAID uye FreeNAS yekuwedzera.
Alan Brown, maneja wetiweki kuUCL akatanga kutaura nezvenyaya yeSMR, akati: "Madhiraivha aya haana kukodzera chinangwa ichi (shandisa muRAID kuvakazve). Nekuti mune iyi chaiyo kesi vanokonzeresa dambudziko rinogoneka uye rinodzokororwa rinotungamira kune zvikanganiso zvakakomba. Madhiraivha eSMR anotengeswa NAS uye RAID ane abysmal uye akasiyana madhiraivha zvekuti haango shandiswe.
Kunyangwe vanhu vanoshandisa Seagate madhiraivha ane SMR vakashuma apo neapo gumi-yechipiri kumbomira mukurekodha, uye avo vakatanga kuita zvine musoro neSMR drive arrays vakasimbisa kuti iyo backup drive yekuvakazve maitiro yakaratidza iri nyaya hombe yavasina kubvuma kusvika. takaedza kuzvishandisa tichizviita.β
