LONDON – SanDisk Corp. has announced the X100 solid-state drive (SSD) for design in to desktop, notebook and thin laptop computers. The unit is available in capacities up to 512-Gbyte and comes with a 6-Gbyte per second SATA interface and it comes in a 2.5-inches form-factor but at only 9.5-mm or 7-mm deep.
The SSD is based on use of multi-level cell NAND flash memory ICs and has a layered caching structure as well the means to support multiple sets of streaming data.
The SanDisk SSD offers up to 500-megabyte per second sequential read/write speeds, and enables a user to copy a 4-Gbyte high-definition movie in less than 10 seconds. In addition to the standard 2.5 inch form factor, the X100 SSD also comes in mSATA and customized thin form factors to address the emerging ultra-thin laptop market.
The SanDisk X100 SSD achieves long-term reliability of 2 million hours MTBF through use of continuous background error checking and advanced NAND recovery mechanisms. The power consumption at 3.3V is 150-mW in active mode and 75-mW on standby.
"With the introduction of the X100 SSD, SanDisk now offers OEMs a complete selection of SSD storage choices," said Kevin Conley, senior vice president and general manager of client storage solutions at SanDisk (Milpitas, Calif.), in a statement. "From the smallest BGA form factors of the iSSD to the economical lower power U100, all the way up to the high performance and high capacity points of our new X100, SanDisk offers a solution to meet the needs of notebook, desktop and ultra-thin laptop manufacturers."
The drive is available now for sampling to PC manufacturers and production-volume shipments.
It's hard to determine how this is going to be different from the current crop of SSDs. 'Multiple sets of streaming data' might be a clue. Are they using the same controllers that everyone else is? Are they coming in at a lower price point?

I am not sure why they stick to this 2.5inch formfactor for SSDs, when they can make it really much smaller. Because of the form factor, ultra thin laptops like macbook air, directly uses a smaller PCB with a few flash chips sticked on it. And this reduces the upgrade options for the notebook.
By maintaining the 2.5 inch form factor, they make it easier for PC manufacturers to offer an option of either HDD or SSD in what is otherwise the same PC. Then the customer can decide the economic tradeoff between cost and speed based on individual needs.
