Western Digital announces a new high-capacity 3.5-inch HDD for data centers. The WD Re+ will be available in versions of up to 6 TB. All of them are designed with power-saving ideas in mind; hence, their maximal power consumption index does not go above 6 W. The new-comer employs five-platter architecture and SATA 6 Gb/sec interface that guarantees the maximal efficiency level. Moreover, its MTBF index approximates 1.2 million hours on average workload index of 550 TB per year.
The WD Re+ is distinguished by the following advantages:
— the incorporation of dual actuator positioning system that improves the drive’s working efficiency;
— the implementation of RAFF technology that monitors HDD parameters in real time and compensates for the linear and angular vibration;
— the employment of StableTrac technology that reduces vibrations and stabilizes drive platters;
— the usage of TLER technology that prevents latencies or an abrupt destruction of RAID … …
Seagate has geared up a surprise for all devotees of Small Office Home Office (SOHO) network storage solutions.

Spéis atá ag fás i bithmhéadracha feistí é de ghnáth a bhaineann leis an diansaothrú ar an bhagairt domhanda córais ríomhaireachta agus córais slándála i Gcoitinne. Cad iad na feistí agus cad iad na buntáistí?
Bithmhéadracha feistí – chuid córas cosanta, monatóireacht agus rialú a dhéanamh ar rochtain ar Ríomhaire, scanóirí, optúla scríbhinn agus gléasanna eile. Gach ceann de na feistí a bhaineann le statach paraiméadair an duine (méarlorg, lámh céimseata, infridhearg patrún an duine) nó dinimiciúil a paraiméadair (guth, scríbhneoireachta). Le haghaidh an fheidhmíocht na n-codanna a chomhdhéanann í a bheith tiománaí bithmhéadracha feistí.
An bonn de gach bithmhéadracha feistí atá in eilimintí braite, braiteoirí brú, micreafóin, termokamera scríbhinn feistí - a bhfuil crua-earraí-bhunaithe chóras eithne. Is déanaí a ceapadh chun a léamh agus a thiontú ar an bithmhéadracha paraiméadair i bhfoirm dhigiteach, a thuilleadh a shimpliú an díchódaithe de na sonraí.
De bithmhéadracht an teicneolaíocht anois níos mó a úsáidtear a chosaint ar an ríomhaire chórais. Cuireann siad ar chumas leat chun go hiomlán slán an bpost, go raibh maith agat a scanóir speisialta a identificeret úsáideoirí méarlorg, ag ligean rochtain a fháil ar na sonraí, ina sonrófar na cearta de gach úsáideoir, etc. a Shocrú ar an paraiméadair bhithmhéadracht, chun srian a chur agus a leathnú na ceadanna rochtana le haghaidh an sainchumas mar riarthóirí an chórais (mar shampla, i dtimpeallacht corparáideach) agus úsáideoirí aonair (oifig bhaile).
Mar gheall ar fhorbairt mhear a aithint teicneolaíochtaí, dá réir sin, tá níos mó cláir atá dírithe ar hacking ar RÍOMHAIRE. Chun cosc a chur ar rochtain neamhúdaraithe ar na sonraí, is gá duit a íoslódáil tiománaithe do bithmhéadracha feistí. Ar ndóigh, an rialta cothrom le dáta ar na tiománaithe pacáiste ceadaíonn ní amháin chun feabhas a chur gnéithe slándála, ach freisin a bhaint as an gcóras ina iomláine.
