Como prometi\u00f3, Western Digital entregar\u00e1 los primeros discos duros con un volumen de almacenamiento de 28 TB en el cuarto trimestre del a\u00f1o. Como se\u00f1ala el fabricante, se entregar\u00e1n en \"grandes cantidades\". En el sector de la nube existe actualmente un gran inter\u00e9s por los discos duros con tecnolog\u00eda SMR.<\/p>\n

En la competici\u00f3n por la mayor capacidad de almacenamiento de los discos duros convencionales de 3,5 pulgadas, ahora hay un empate virtual entre Seagate y Western Digital. Seagate ha anunciado su primer disco duro de 24 TB<\/a> en CMR y una opci\u00f3n de 28TB en SMR en octubre, las 2 tecnolog\u00edas utilizadas en la fabricaci\u00f3n de discos duros que hemos comparado<\/a>.<\/p>\n

Ultrastar DC HC680 con 28 TB y SMR<\/h2>\n

Western Digital anunci\u00f3 el primer disco duro de 28 TB este verano y est\u00e1 cumpliendo su promesa de entregarlo en el cuarto trimestre de 2023. Sin embargo, estar\u00e1 disponible inicialmente para las plataformas de almacenamiento h\u00edbrido de la empresa, Ultrastar Data60 y Ultrastar Data102, a partir de diciembre. Las ventas individuales no se esperan hasta el primer trimestre de 2024, lo que tambi\u00e9n se aplica al HC580 con 24 TB en CMR.<\/p>\n

A\u00fan no se dispone de todos los detalles del Ultrastar DC HC680 de 28 TB. Al igual que los modelos de 26 y 27 TB de la serie, los discos magn\u00e9ticos giran a 7.200 rpm en una carcasa sellada llena de helio. Se dice que la versi\u00f3n de 28 TB alcanza velocidades de hasta 265 MB\/s y tiene 512 MB de cach\u00e9. Est\u00e1 dise\u00f1ado para una carga de trabajo de 550 TB al a\u00f1o.<\/p>\n

El uso de la grabaci\u00f3n magn\u00e9tica en tablilla (SMR) significa que las pistas de datos est\u00e1n dispuestas de forma superpuesta para lograr una mayor densidad de almacenamiento. Si se reescriben \u00e1reas de datos, las pistas adyacentes tambi\u00e9n deben actualizarse, lo que puede provocar una ca\u00edda del rendimiento. Debido a este inconveniente, los discos duros SMR se utilizan principalmente para tareas que requieren cargas de escritura poco frecuentes. Adem\u00e1s, se utilizan las t\u00e9cnicas eAMR y OptiNAND.<\/p>\n

La tecnolog\u00eda SMR se extiende a la nube<\/h2>\n

Aunque los discos duros SMR tienen bastante mala reputaci\u00f3n (en parte debido a que la tecnolog\u00eda est\u00e1 oculta), cada vez son m\u00e1s aceptados en los centros de datos en nube, afirma Western Digital. \"\u00a0Las unidades SMR de 26 TB de Western Digital ya representaron casi la mitad del total de exabytes enviados a centros de datos en el primer trimestre del a\u00f1o fiscal 2024.<\/em>\", dice el comunicado de prensa actual de la empresa.<\/p>\n

Ed Burns, director de investigaci\u00f3n de discos duros y tecnolog\u00edas de almacenamiento de la empresa de estudios de mercado IDC, est\u00e1 de acuerdo: \"Vemos un fuerte impulso en las iniciativas SMR de Western Digital y esperamos que la adopci\u00f3n de SMR siga creciendo. Este nuevo disco duro SMR de 28 TB ofrece atractivas ventajas de coste total de propiedad que los clientes de la nube no pueden ignorar.<\/em>\", se cita a Western Digital.<\/p>\n

24TB CMR como Ultrastar y WD Gold<\/h2>\n

Los discos duros que no utilizan la tecnolog\u00eda SMR se clasifican como CMR (grabaci\u00f3n magn\u00e9tica convencional). Sin las desventajas de la SMR, ofrecen menos espacio de almacenamiento. Al igual que Seagate, el m\u00e1ximo actual de Western Digital es de 24 TB.<\/p>\n

El Ultrastar DC HC580 con 24 TB est\u00e1 dise\u00f1ado para grandes centros de datos, con una velocidad m\u00e1xima de 298 MB\/s, seg\u00fan la p\u00e1gina del producto.<\/p>\n

No se ha facilitado informaci\u00f3n sobre la disponibilidad del WD Gold de 24 TB. En cuanto al precio, se espera que sea superior al del WD Gold de 22 TB, que cuesta 550 USD directamente del fabricante y unos 570 EUR en plataformas de comercio electr\u00f3nico.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
