HGST Delivers First 10TB Enterprise HDD for Active Archive Applications
HGST today announced the first enterprise-class 10TB (terabyte) hard disk drive (HDD) for next-generation active archive applications. The host-managed Ultrastar Archive Ha10 SMR HDD enables dense server and storage systems. This product is the result of combining two complementary technologies ? HGST?s second generation HelioSeal platform and shingled magnetic recording (SMR).
SMR is a core technology necessary in driving areal density increases. By overlapping or "shingling" the data tracks on top of each other, higher areal density can be achieved within the same physical footprint. This layering is typically managed by the drive, without host-level intervention. That approach is great for compatibility, but according to HGST, it can result in inconsistent performance and dramatic slowdowns over time. The firm claims its host-managed SMR solution can smooth out those wrinkles with custom software.
The drive is rated at two million hours mean time between failure (MTBF), offers a five-year limited warranty, a 10-15 unrecoverable reduced bit error rate, rotational vibration safeguards, and 600K load/unload cycles.
The Ultrastar Archive Ha10 uses seven platters stacked inside the chassis that rotate at 7,200 RPM. Don't expect impressive performance, though. Compared to He8's 205MB/s sequential specs, the Ha10's 157MB/s read rate and 68MB/s write speed are plodding at best and crawling at worst.
The HGST Ultrastar Archive Ha10 HDD is not a drop in replacement for today?s enterprise-capacity HDD so it won't be available through conventional channels. HGST's host-managed SMR implementation requires substantial customization on the software side. SMR hooks can also be integrated into the file system and applications. That's all possible in Linux now with an open-source SDK available on Github. HGST also expects some native driver and file system support for host-managed SMR by late 2016, but only for server platforms.
Initial rollout of the 10TB HDD is focused on cloud and HGST's OEM storage customers who have the in-house capability to develop the software required.
