Intel SSD Roadmap Points To 2TB Drives Arriving In 2014 183
MojoKid writes "A leaked Intel roadmap for solid state storage technology suggests the company is pushing ahead with its plans to introduce new high-end drives based on cutting-edge NAND flash. It's significant for Intel to be adopting 20nm NAND in its highest-end data center products, because of the challenges smaller NAND nodes present in terms of data retention and reliability. Intel introduced 20nm NAND lower in the product stack over a year ago, but apparently has waited till now to bring 20nm to the highest end. Reportedly, next year, Intel will debut three new drive families — the SSD Pro 2500 Series (codenamed Temple Star), the DC P3500 Series (Pleasantdale) and the DC P3700 Series (Fultondale). The Temple Star family uses the M.2 and M.25 form factors, which are meant to replace the older mSATA form factor for ultrabooks and tablets. The M.2 standard allows more space on PCBs for actual NAND storage and can interface with PCIe, SATA, and USB 3.0-attached storage in the same design. The new high-end enterprise drives, meanwhile, will hit 2TB (up from 800GB), ship in 2.5" and add-in card form factors, and offer vastly improved performance. The current DC S3700 series offers 500MBps writes and 460MBps reads. The DC P3700 will increase this to 2800MBps read and 1700MBps writes. The primary difference between the DC P3500 and DC P3700 families appears to be that the P3700 family will use Intel's High Endurance Technology (HET) MLC, while the DC P3500 family sticks with traditional MLC."

Pathetic write endurance. (Score:4, Informative)
P3500 = 374TB for 2TB model = 2 days of continuous writing and drive dies = mlc
P3700 = 50 days of continuous writing = slc
while old Samsung 830 routinely did >1PB with 256GB model.
No, you wont write 20GB per day, those are not home use drives, they go into servers and get killed by bcache.

I dislike SSDs because when they fail they do it catastrophically.
Huh? The typical failure mode for an SSD that hits its write limit is actually to simply become read only. Compared to an HDD's likely "all your data is gone", I'd hardly call that catastrophic.
