Information about Intel's next-gen SSDs has leaked out. Myce has published a collection of slides detailing several drives due to be released in the second quarter of next year. The big daddy is Fultondale, otherwise known as the DC 3700 Series. According to the slides, this puppy will sport up to 2TB of high-endurance MLC NAND. The server-focused drive will be available as a PCIe add-in card and in a standard 2.5" form factor.
Interestingly, the slide suggests that both implementations have finned heatsinks. The P3700 Series is said to draw up to 25W of power, and it should be pretty quick. The spec sheet quotes performance ratings of 2800MB/s for sequential reads and 1700MB/s for sequential writes. Expect the drive to push 450k IOps with random reads and 150k with random writes.
Pleasantdale appears to be closely related Fultondale. Also known as the DC P3500 Series, this drive will be available in the same form factors as the P3700, and its performance ratings look similar. The only big differences are the random write rate, which is listed as just 40k IOps, and the endurance, which is limited to 374TB of total writes. The DC P3500 Series will use standard MLC NAND rather than the high-endurance stuff employed by its big brother. That model is rated for 10 full drive writes per day for five years—a staggering 36 petabytes for the 2TB version.
The final drive on the leaked schedule is Temple Star, a.k.a. the Pro 2500 Series. This is a client-oriented model, though the Pro moniker suggests it's aimed at businesses and system builders rather than individual consumers. The slides say the Pro 2500 Series will be come in M.2 and 2.5" flavors with capacities up to 360GB for the former and 480GB for the latter. The 540MB/s max sequential transfer rate suggests the Pro 2500 Series can't tap into the extra bandwidth available in the M.2 interface. Perhaps it's based on a current-gen controller.
All of these upcoming drives are reportedly equipped with 20-nm NAND. One might expect Intel to use flash built with finer fabrication techniques, but keep in mind that these models are aimed at corporate customers. Intel typically rolls out new flash memory in its consumer-oriented drives first. Unfortunately, there are no details on what's coming on that front.
