Samsung cranks up the speeds of its solid-state drives

Solid-state disks (SSDs) are seen as the next plateau for mobile computing. Companies like Alienware and Dell offer the high-performance drives in their notebook computers and end-users can add SSDs to their own notebooks thanks to online retailers like Newegg.

Samsung first starting making waves in the SSD arena with its 32GB drive in March 2006 and followed up with a faster 64GB unit in June of 2007. Today, Samsung is once again stepping up its efforts in the SSD arena.

The company has announced a new generation of 64GB SSDs which use 8Gb, 50nm single-level-cell (SLC) flash memory chips. The drives, which will be available in 1.8" and 2.5" form-factors, also feature a new SATA II interface for faster performance.

The faster chips and SATA II interface gives the new SSDs sequential write speeds of 100MB/sec and sequential reads of 120MB/sec. These numbers completely obliterate the previous Samsung 64GB offering which is rated at 45MB/sec write and 65MB/sec read. Samsung's first-generation 32GB SSD is rated for 30MB/sec writes and 53MB/sec reads.

"The 64GB SATA II SSD is based on Samsung’s cutting-edge NAND technology with dramatically improved performance specs that are taking system performance to a whole new level of efficiency," stated Samsung director of NAND flash marketing Jim Elliott.

Samsung's new SSDs also now compare favorably with Mtron's family of SSDs which are available in 2.5" and 3.5" form-factors. Those drives feature write speeds of 90MB/sec and read speeds of 120MB/sec.

Samsung is currently sampling the new SATA II SSDs and production examples should follow in early 2008.

Can anyone comment on the differences between flash memory used in SSDs and those used in flash drives?

The current prices on NewEgg for SSDs come out to around $30/GB.

Where as other kinds of fast flash memory (like Sandisk Extreme III types) run around $10 to $15 per GB (depending on form-factor: SD, CompactFlash, Thumb drive)

if you want a fast flash drive you go with single-level cell (slc) nand flash technology. most cheap memory cards and usb drives use mlc nand flash and it can be hard to distinguish between slc and mlc variants (apart from the price diff). i can tell you that corsair's blue usb drives use mlc (slow, cheap) but their red variants use slc.

Can anyone comment on the differences between flash memory used in SSDs and those used in other flash drives?
that makes more sense

Price is not a good indicator, for example Sandisk's Extreme III is SLC. Write speed is a better indicator, then read speed. TYpically you won't see any products up near the 40MB/s read mark unless SLC, but the difference in Samsung's product has to be the controller chip's access strategy unless they suddenly made a giant breakthrough in flash chips' performance which seems unlikely.
