Flash-based solid state drives (SSDs) have historically been the poor cousins to platter-based HDDs in terms of storage capacity, making them a poorer option for enterprise applications. But SanDisk is looking to change things with its new Optimus MAX SSD, the world's first 2.5-inch Serial Attached SCSI (SAS) SSD packing 4 TB of storage capacity.

Touting the new drive as the first true replacement for legacy mission-critical data center SAS HDDs, SanDisk claims the 4 TB Optimus MAX SSD allows enterprises to maintain their current SAS storage infrastructures, while providing improved, cost-effective performance, and generating less heat and consuming less power than HDDs.

Just exactly how cost effective the new drive is remains to be seen as SanDisk hasn't revealed pricing details, but it is claiming sequential read/write speeds of up to 400/400 MB/s and random read/write speeds of up to 75,000/15,000 Input/Output Operations Per Second (IOPS) for the drive via its SAS 6 Gb/s interface.

Although the thought of slotting a 4 TB SSD into your laptop might sound appealing, SanDisk is targeting the drive at read-intensive applications with typical workloads made up of a read/write ratio of 90/10. This includes data warehousing, media streaming, web servers, video on demand (VOD), and web-based applications.

"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," says John Scaramuzzo, Senior Vice President and General Manager, Enterprise Storage Solutions at SanDisk. "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."

The most important parameter has not been disclosed. It seems that SanDisk hopes "enterprise" customers will be less concerned with that parameter than "regular" customers; but I think otherwise.


Yes it's only for enterprise and no doubt outrageously expensive, but still pretty significant in that HDD seems to have stalled out a bit lately. There are no laptop height 2TB or larger drives yet for instance and no 2.5" 4TB period. But SSD makers continue to shrink size and expand capacity and reduce cost more or less in accordance with Moore's Law. At the current rate it seems SSD is poised to essentially reach cost parity with HDD in maybe 3-5 years. Also our devices of choice already rule out HDD in so many cases as with ultrabooks and tablets.

I even wonder if HDD makers must see the writing on the wall and will spend less R&D on HDD, slowing its development even more relative to SSD.
