Transcend Develops SuperMLC NAND Technology
Bohs Hansen / 5 years ago
Here I sat thinking that I knew all the terms for the different NAND technologies and then Transcend comes along with a new one that they have called SuperMLC. SuperMLC was developed as a more cost effective solution to SLC NAND with a performance that comes very close. In fact, the write performance is up to four times better than traditional MLC-based products.
Okay, I have to be honest right away and say that this technically isn’t a new form of NAND, we’re still dealing with Multi-Level Cell NAND chips. The difference comes down to how this NAND is handled by the SSD controller and its firmware. By using high-quality NAND chips and reprogramming the firmware, Transcend essentially created a cell-based RAID setup where the same data is stored in both bits in the same cell instead of having different data stored in the two. This naturally decreases the available capacity per NAND chip by half, but it also allows the drives to deliver a much better performance. In fact, the new SuperMLC has up to four times the sequential write performance when compared with traditional MLC NAND. It also brings better lifetime expectancy with up to 30,000 P/E cycles.
Transcend will release new drives based on this technology in early 2016 and they are all aimed at the enterprise sector where both initial costs and total costs of ownership really matters. That doesn’t mean that you can’t purchase these drives and use them in your personal setup, if that is something you are considering. Among the upcoming products with this brand new SuperMLC technology are a 2.5-inch SSD (SSD510K), an mSATA SSD (MSA510), a half-slim SSD (HSD510), and two M.2 SSD models. (MTS460 & MTS860).
What do you think of this way to utilize the NAND chips? Would this be an option you would be interested in, or do you prefer the normal MLC NAND for capacity or SLC NAND-based products for their reliability and performance? Let us know in the comments.
