Samsung doubles its SSD capacity

Two months ago, Samsung announced its new SATA II-based 64GB solid-state disk (SSD). The 64GB SSD promised read speeds of 120MB/sec and write speeds of 100MB/sec.

Today, Samsung is doubling the capacity of its latest SATA II SSD offering to 128GB. Instead of relying on single-level cell (SLC) NAND flash memory, the new 128GB offering makes use of multi-level cell (MLC) NAND flash.

Unfortunately, performance dropped with the new 128 SSD -- read speeds are down to 100MB/sec while write speeds hover at 70MB/sec.

“Our SSD can be used by the widest range of corporate notebooks, particularly where additional storage is needed beyond what is typical in most business applications,” said Jim Elliott, director of flash memory marketing for Samsung Semiconductor.

Samsung's new 128GB SSD pales in comparison to BiTMICRO's massive 832GB SSD which was recently announced. Samsung, however, has the advantage when it comes to availability and pricing. Samsung's 128GB SSD will be available in the first half of 2008 with pricing of at least a couple thousand dollars.

BiTMICRO's 832GB SSD, on the other hand, won't be mass produced until the latter half of 2008 and will likes cost tens of thousands of dollars.

Mtron uses SLC so it can last 100k cycles of erase/program each block.

The MLC from Samsung I have seen in the lab only guarantees 500 cycles, but typically last 3000, so no matter how much wear leveling is in there, if you use all the space alot (i.e. in server or as a swap partition), then it won't last that long, for sure.

I think this MLC type drives can only be used for video or light duty app like laptop. For high performance computing like workstation or server, MLC won't cut it at all.
