SanDisk Announces TLC Based Ultra II SSD — Over 90,000 Read IOPS For 50Cents/GB!

SanDisk Corporation, a world-leading producer of flash storage solutions, is announcing the Ultra II SSD, their first TLC memory equipped SSD, which is being targeted to the mainstream notebook and PC market.  Notebook-compatible SSDs continue to increase in capacity, at the same time as they continue to go down in cost.  More and more laptops and notebooks are shipping with pre-installed SSDs rather than traditional HDDs, with even these as potential candidates for capacity and/or performance upgrades.

The continued proliferation of tablets and smartphones has driven users to increasingly expect instant-on and immediate response times.  The enhanced multi-tasking capabilities of today’s machines has enabled users to take full advantage of their machines for both work and entertainment.  With all of this increased usage, battery life becomes even more important.

SanDisk’s Ultra II SSD delivers up to 28X better performance than a typical hard disk drive (HDD). including quicker boot-up times, application loading and an overall more responsive user experience.  SanDisk was able to enhance the speed and endurance of the Ultra II SSD by utilizing their proprietary nCache 2.0 technology.

Am I correct that this is the same size as will fit in my MacBook Air as a had at 240 gb?


If your Mackbook air uses a Hard Disk then it will fit. If it uses flash storage then I’m not sure. Did you mean to type ‘HDD’ when you typed ‘had’ ?.

I wonder what write speeds can this pull off, when SLC runs out..
