Samsung 2.5" SATA II Solid State Drive sample  (Source: Samsung)
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.

I think we got past that 10-20 years ago, with today's NAND memories that are good for 1-10M cycles, plus wear leveling algorithms built into all these drives. SSDs should be much more reliable than magnetic HDDs.

Huh? 10-20 years ago? Maybe I've been in a coma, but last time I checked, flash memory was not even available 10 years ago, much less 20. Ok, maybe 1997 or 1998 it became available to the general computing public, but we certainly did not "get past" the lifecycle limitations. Don't know where you came up with this.

voyager 1 and 2 had flash based mem =) i dunno about sputnik
HDD do not like space.

Flash memory came out in the late 1980's, and using flash for a file system was one of the early applications of flash, since file systems had been implemented on top of RAM and EEPROM prior to flash.

Maybe it had been invented in the late 80's, but it certainly was not widely available to consumers until the late 90's, with the popularity of digital cameras.

And even then, the write/rewrite cycles were pretty limited, at least for affordable memory modules.

Nice try, you are just digging yourself deeper trying to defend your original statement.

Have you ever heard of people throwing away flash memory because it ran out of read/write cycles. No, it usually becomes obsolete well before that time.

As the read/write requirements have increased, the technologies that have been developed over last 2 decades have been successful in keeping up.

Jut because the read/write cycles were more limited 10-20 years ago doesn't mean they didn't develop strategies to maximize the cycles required in the day . And whether they were available to the general public also has no bearing on whether they were able to develop said strategies. Give up the fight buddy.

Digging myself deeper? There's a HUGE difference between using your 1999-technology Compact Flash card on a digicam and using it as operating system drive. In a digicam, or even a USB thumb drive in a PC, we're talking about dozens, hundreds, or maybe just low-thousands of read/write cycles. Try using it as an OS drive, with the friggin' page file performing thousands of writes per minute and it's a totally different story.

The post I was responding to stated that this problem was "solved" 10-20 years ago. I'm not saying that the write cycle problem is not a problem with flash memory today -- I'm only arguing that it was not "solved" 10-20 years ago as the poster who I was responding to stated. Stay out of this thread if you're not going to even read what I wrote.
