SanDisk has updated its CloudSpeed line of solid state drives aimed at the data centre with updated CloudSpeed Ultra models offering up to 1.6TB of usable capacity for customers with latency-sensitive transactional workloads such as e-commerce and online services.
The CloudSpeed Ultra Gen II SSDs will be available from this month for selected cloud service provider customers, followed by a staggered release through the Enterprise Channel Partner programme, SanDisk said.
Designed to offer the storage performance and density required for cloud and data centre workloads, the CloudSpeed Ultra Gen II drives are claimed to offer the best price/performance.
This equates to a performance level of 32,000 input/output operations per second (IOPS) when writing 4KB blocks, with 530MBps throughput and 80 microseconds latency for random reads and writes.
SanDisk claims that the new drives will cost just $0.04 per IOPS against a typical figure of $3.50 for conventional Sata hard drives.
"The demand for transaction-oriented applications puts tremendous strain on our cloud service provider customers to architect data centre platforms capable of delivering high performance, while keeping infrastructure costs in check," said SanDisk's senior vice president for enterprise storage solutions, John Scaramuzzo.
SanDisk unveiled the CloudSpeed brand last year, comprising the CloudSpeed Ascend, Ultra, Eco and Extreme lines, each with differing endurance and performance characteristics.
The CloudSpeed Ultra models are optimised for latency-sensitive applications and mixed-use workloads, offering predictable random I/O write performance, according to SanDisk.
As with the other CloudSpeed lines, the new drives are offered in an industry-standard 2.5in drive form factor with a 6Gbps Sata host interface. Capacities of 400GB, 800GB and 1.6TB are available initially, and the drives are based on SanDisk's 15nm multi-level cell flash chips.
The CloudSpeed Ultra Gen II drives also feature SanDisk's Guardian Technology, which provides a combination of error correction and detection, full data path protection and data fail recovery. Thanks to this, SanDisk covers the new drives with a limited five-year warranty.
