SanDisk announces 4TB SSDs, 8TB & 16TB SSDs to follow

I bet these will be expensive!.

SanDisk has announced a new 4TB flash drive, double the capacity of the biggest solid-state drive available today.

 

The 4TB Optimus MAX – which sounds like the big bad brother of an Optimus Prime toy – follows the 2TB Optimus Eco, a technology SanDisk acquired when it bought SMART Storage.

 

The new SSD can take three full drive writes a day for five years. It has a SAS interface and its basic performance numbers are as follows (with previous Eco numbers in brackets for comparison):

 

• 75,000 random read IOPS (Optimus Eco: 100,000)
  
• 15,000 random write IOPS (Optimus Eco: 45,000)
  
• 400MB/sec sequential read and write (Optimus Eco: 500MB/sec)
  

Why is the MAX slower than the Eco? SanDisk says the Eco uses 19nm MLC flash while the MAX is made from 19nm eMLC, a better grade of flash but not one that we usually think of as slower – the MAX random write speed being a third of the Eco's.

This is an interesting rumour if true.

 

SanDisk expects that sometimes in 2017 and onward the per-GB price of mission-critical solid-state drives and hard disk drives will be comparable. At the same time, SSDs will offer higher performance, lower power consumption and other benefits.

 

A market rumour suggests that the current-gen 10K and 15K HDDs represent the last generation of mission-critical hard drives as we know them. Going forward there will be other storage devices for this market segment. (Source)
