If you are an enterprise, SanDisk is getting a bit SAS-y with some pretty large SSDs. How large? 4TB. Not large enough? Why are you the way you are. Also, according to VR-Zone, 6TB and 8TB versions will follow, in 2015 (Update: 5/6/2014 @ 5:56pm EST — VR-Zone might have meant "16TB"… as Tom's IT Pro claims to have heard from SanDisk). These drives will be produced with 19nm NAND, not utilizing the 15nm cells from their partnership with Toshiba. SanDisk claims their choice of 19nm was for reliability. Also, clearly, they are not suffering with density.
Speaking of reliability, the SanDisk warranty is rated in both time as well as the supported number of full drive writes per day. The Optimus MAX SSD is rated at one-to-three drive writes per day, or 4-12TB per day, over the course of its 5-year warranty.
4TB Optimus MAX SSDs are expected to launch "to select OEMs and through the channel" in Q3.
