The Ultrastar DC HA340 is an air-filled CMR drive spinning at 7,200 RPM with a 256MB cache, rated for workloads up to 550TB per year and a projected 2.0M-hour MTBF. WD lists transfer rates up to 267MB\/s, rotation-vibration sensors and a 5-year limited warranty. It is overbuilt for a gaming PC's bulk library - which is exactly the point if this drive will hold a media server, NAS or backup target that never sleeps.\u003c\/p\u003e\u003cp\u003eThis is the drive class that fills data centers, sized for builders running serious storage at home or in a small business: a media server that serves the whole house, a backup target for several machines, a surveillance recorder, or a virtualization host that keeps a shelf of virtual machines on one spindle. The HA340 is an air-filled, CMR design, so sustained writes stay consistent when a backup window or a RAID rebuild asks for hours of full-tilt throughput.\u003c\/p\u003e\u003cp\u003eThe enterprise ratings are the real story. WD rates the family for workloads up to 550TB per year with a projected 2.0M-hour MTBF, and rotation-vibration sensors help the drive behave when it shares an enclosure with neighboring drives — the exact condition that makes desktop drives age early. At 7,200 RPM with a 256MB cache and transfers up to 267MB\/s, it also answers faster than the 5,400 RPM bulk drives it will usually sit next to.\u003c\/p\u003e\u003cp\u003eYou give up nothing on fitment: it is a standard 3.5-inch SATA drive that mounts in any NAS, server or desktop bay with SATA power and data. A 5-year limited warranty matches the duty cycle it was built for. Choose the 8TB HA340 when the array is infrastructure — the thing everything else depends on — rather than a place to park files you could re-download.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCapacity: 8TB, 3.5-inch form factor\u003c\/li\u003e\n\u003cli\u003eInterface: SATA; transfer rate up to 267MB\/s\u003c\/li\u003e\n\u003cli\u003e7,200 RPM, 256MB cache, CMR recording\u003c\/li\u003e\n\u003cli\u003eWorkload rating up to 550TB\/year; projected 2.0M-hour MTBF\u003c\/li\u003e\n\u003cli\u003e5-year limited warranty; model WUS721208BLE6L4\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSpecs: 8TB | 3.5in SATA | 7,200 RPM | 256MB cache | CMR | up to 267MB\/s | Part # 0B47078\u003c\/p\u003e","brand":"Western Digital","offers":[{"title":"Default Title","offer_id":46746305298517,"sku":"0B47078","price":587.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0653\/1586\/4661\/files\/ultratar-dc-ha340-hdd-4tb-left.png.wdthumb.319.319.webp?v=1794631273","url":"https:\/\/gearspawn.com\/products\/wd-ultrastar-dc-ha340-data-center-hard-drive-8tb-sata-enterprise-3-5-inch-cmr-hdd-for-servers-and-heavy-duty-storage","provider":"GearSpawn LLC","version":"1.0","type":"link"}
