SanDisk Announces 4TB SSDs, 8TB & 16TB SSDs to Follow

By - Source: Toms IT Pro

SanDisk is unveiling the industry's first 4TB serial attached SCSI solid state drive along with several new 12Gb/s and 6GB/s workload specific SAS SSDs. The Optimus MAX 4TB SAS SSD and Lightning Gen. II SSD product lines, announced today, are updates to SanDisk's SAS product line.

The Lightning and Optimus SAS SSDs each provide solutions to meet specific data center requirements. The Lightning line comes in 12Gb/s and 6Gb/s SAS SSD models that offer a write optimized, read optimized, or a mixed use solution. The Optimus MAX is a large capacity SAS SSD meant to replace legacy SAS hard disk drives in the data center. Read: Selecting the Right Type, Amount & Location of Flash Storage

The Optimus MAX is optimized for read intensive applications such as video streaming, web servers, and database applications; it has a 90/10 read/write mix. The Optimus MAX SSD uses 19nm eMLC NAND flash technology and includes SanDisk's Guardian Technology Platform; a suite of products designed to improve the life and reliability of flash based SSDs. Mean time between failures is estimated at 2.5 million hours by SanDisk.

Main advantages of new 4TB drives, as outlined by the company, include performance and lower power and footprint requirements, due to the higher density drives that would require fewer racks and power supplies in the data center.

Coming Soon: 8TB & 16TB Optimus MAX SSDs

The goal of surpassing current HDD size limits doesn't end with the 4TB Optimus MAX. "We see reaching the 4TB mark as really just the beginning and expect to continue doubling the capacity every year or two, far outpacing the growth for traditional HDDs”, says Manuel Martull, SanDisk Product &Solution Marketing Director. Dates were not specified in the written press materials, but 8 TB and 16 TB drives are definitely in the works according to a phone conversation with SanDisk.

"Customers have been looking for a way to transition their data centers from HDDs to NAND flash, but have been forced to decide between cost and performance, or give up important functionality. The Optimus MAX eliminates the need for compromises. We believe that the Optimus MAX will be a disruptive force within the storage industry, catalyzing many organizations to make the switch from their HDD-prominent data center infrastructures to SSDs," said John Scaramuzzo, Senior Vice President and General Manager, Enterprise Storage Solutions at SanDisk.

Lightning Ultra Gen II SSDs

The Lightning Ultra Gen. II SSDs are workload optimized and come with a 12Gb/s interface speed that doubles throughput of 6GB/s SAS SSD versions. There are three models within the Lightning Ultra Gen. II SSD group and each is optimized for a specific purpose.

  • Lightning Ultra Gen. II SSD -- optimized for write-intensive applications such as high performance computing (HPC) and database logging and is available in 200GB, 400GB, and 800GB capacities. The SSD can handle up to 25 full capacity drive writes per day (DWPD). The SSD delivers up to 190K/100K IOPS of random read/write performance and sequential read/write speeds of up to 1000/600 MB/s 3 for write-intensive application workloads.
  • Lightning Ascend Gen. II SSD -- optimized for mixed-use application workloads such as Virtual Desktop Infrastructure (VDI), Exchange and File Servers, On-line Transaction Processing (OLTP) and E-Commerce and is available in 200GB, 400GB, 800GB, and 1.6TB capacities. The SSD can handle up to 10 full capacity drive writes per day and delivers up to 190K/80K IOPS of random read/write performance and sequential read/write speeds of up to 1000/600 MB/s.
  • Lightning Eco Gen. II SSD -- an entry-level SSD and is designed for read-intensive application workloads such as data warehousing, media streaming, and cloud computing and is available in capacities of 1TB and 1.6TB. The SSD can handle up to 3 full capacity drive writes per day and delivers up to 180K/35K IOPS of random read/write performance and sequential read/write speeds of up to 1000/500 MB/s.
