Seagate has brought their Turbo SHHD into the Enterprise Performance product line with the second-generation TurboBoost models. This provides two options for those seeking the fastest HDD storage available: the standard 15K v5 model, or TurboBoost models. TurboBoost models are accentuated with a 32GB layer of eMLC flash for application acceleration.
The move to a faster 12Gb/s interface and a LSI/Seagate controller boosts cache performance over the previous revision. The drive also operates in an NVC-enabled (Non-Volatile Cache) write-back mode, which boosts performance for data not promoted into cache. The value of intelligent identification and acceleration of hot data provides a seamless increase in application performance. TurboBoost models simplify the process of deploying flash-based caching, and alleviate management requirements. Unlike some software-driven tiering and caching implementations, this drive analyzes data internally, and moves it to cache without user intervention; there is no wait for data shuffling between tiers. This alleviates inter-server and network data movement.
The industry is moving to flash solutions for performance-driven workloads, and SSHDs provide an easy means of deploying large amounts of flash into the server. Deploying 16 TurboBoost SSHDs provides a 512GB shot of flash acceleration into the server in the form of a slip-in solution that can replace existing drives. The increased performance boosts overall server efficiency and output without the need for costly software and hardware.
Many decision-makers will choose either 15K HDDs or faster SSDs, but value SSDs do not feature as much endurance as SSHDs, nor do they come with the venerable SAS connection. The eMLC NAND flash employed on the TurboBoost models, along with selective data caching, provides plenty of endurance for any workload during the warranty period.
In tests designed to ferret out the benefits of caching, we found the Enterprise Performance TurboBoost model exhibits excellent performance with cached data. With a full NAND buffer, we reached 5,000 IOPS within a tight latency range. In a more advanced test with a simulated hot band of data, we were able to reach 1,500 IOPS.
These tests highlighted the performance of data promoted to cache, but the TurboBoost 15K HDD architecture also provides a boost for "normal" data with its write-back caching mode. We continued to note appreciable performance gains and reduced variability with write workloads when we tested the full surface of the drive. The TurboBoost also fell within the normal power envelope of a 15K HDD, but exhibited a notable decrease in power consumption in sequential workloads.
Overall, the Enterprise Performance TurboBoost 15K HDD continues to impress. Enterprise-class features such as a five-year warranty, SED, and FIPS 140-2 models, and a two-million hour MTBF, highlight the fact that SSHD technology can provide the same reliability and features as standard 15K models. The Enterprise Performance TurboBoost 15K HDD provides performance well beyond typical short-stroking techniques, which is why it has earned the TweakTown Best Performance award.
