SSD Write Endurance 25nm Vs 34nm

[Computurd]

the 720 is a PCIe device, not a SSD. their enterprise SSDs will be eMLC. the 710 is the Enterprise drive, and it will be eMLC.

The reshaped roadmap seen by X-bit labs postpones introduction of code-named Lyndonville solid-state drives for enterprise markets to Q1 2011 from the last quarter of this year. However, thanks to such delay, the new drives will utilize eMLC NAND made using 25nm process technology, which has considerably higher amount of write cycles than traditional MLC, even though single-level cell (SLC) NAND still boasts even higher number of write cycles.

Even though specifications of 25nm eMLC flash are not presently available, 34nm eMLC NAND from Micron, Intel’s partner in IM Flash achieved 30 thousand write cycles – a 6x increase in endurance when compared to standard MLC NAND. In addition, last year Micron also introduced a 34nm SLC Enterprise (eSLC) NAND device that achieves 300 thousand write cycles – a 3x increase in endurance when compared to standard SLC NAND

they will have the eSLC on the PCIe devices. note the use of "device" instead of drives.

The Intel 700 Series is meant to replace the X25-E lineup, Intel’s enterprise series, which hasn’t been updated since late 2008 so it’s long overdue. However, neither of these is an exact successor. The 710 Series is closer with its 2.5″ form factor and SATA 3Gb/s. The 710 Series is actually pretty close to the 320 Series in terms of specs: sustained write is slightly higher but random performance is a bit lower. The biggest difference between the 320 and 710 series is the NAND type. 320 Series uses regular MLC that you can find inside any mainstream SSDs; 710 Series is Intel’s first enterprise level SSD to use MLC NAND, but not just any kind of MLC—it will use MLC-HET NANDs. MLC-HET offers more write cycles per cell so longetivity is increased, which is crucial for enterprises. The only downside is that MLC-HET will only last for 3 months after all write cycles have been used, whereas normal MLC will last for 12 months. However, this shouldn’t be an issue due to the increased amount of write cycles. For the record, MLC-HET with 20% over-provisioning (OP) appears to offer roughly 65 times greater endurance than normal MLC
