While announcing the launch of its new line of 4TB enterprise-class SSDs this week, SanDisk also said it plans to up the ante for capacity.

The Lightning Ultra Gen. II SSD offers up to 25 full capacity drive writes per day. It delivers up to 190,000 and 100,000 IOPS of random read/write performance and sequential read/write speeds of up to 1,000 MBps and 600 MBps, respectively. The drive comes in capacities ranging from 200GB to 800GB.

The Lightning Ascend Gen. II SSD has lower endurance and can provide up to 10 full capacity drive writes per day. The drive is aimed at applications with respectable write performance, but is tuned for heavier read workloads such as virtual desktop infrastructure (VDI), Exchange and file server use, and online transaction processing (OLTP).

The Lightning Ascend SSD delivers up to 190,000 random read and 80,000 write IOPS and sequential read/write speeds of up to 1,000 MBps and 600 MBps, respectively. The SSD is available in capacities ranging from 200GB to 1.6TB.

The Lightning Eco Gen. II SSD is considered SanDisk's entry-level enterprise SSD and is designed for read-intensive application workloads such as data warehousing, media streaming, video on demand and cloud computing. It can sustain up to three full capacity drive writes per day. The Eco SSD is available in capacities of 1TB and 1.6TB and delivers up to 180,000 random read and 35,000 write IOPS and sequential read/write speeds of 1,000 MBps and 500 MBps.

According to Gartner, some SSDs will nearly reach price parity with hard disk drives by 2017
