Samsung MLC SSDs promise 20 times improvement in lifespan

Throw a rock in the tech world and it can’t help but hit a few research firms touting the fact that solid state drives (SSDs) will be replacing traditional HDDs in computers of the future. The SSD has some benefits, but for now the price and capacity of the SSD simply rule it out for enterprise and consumer use for the most part.

Samsung announced that its latest SSDs are now in volume production. The new SSDs will be available in 128GB and 64GB capacities. The capacity isn’t what sets these drives apart, rather it’s the multi-level cell (MLC) technology used in the Samsung SSDs.

According to Samsung the new MLC SSDs are capable of providing read speeds of 90MB/s and write speeds of 70MB/s -- performance on par with SSDs using single-level cell technology. The difference is that SSDs built on the MLC technology offer about a 20 times improvement in the typical 4-5 year lifespan of a PC hard drive. Power consumption is another big feature of the MLC SSDs with requirements for 0.2 watts in standby and 0.5 watts in active mode.

Jim Elliott, VP memory marketing for Samsung Semiconductor said in a statement, “With the 64 GB and 128 GB MLC SSDs, we are satisfying the density requirements of most business users and many PC enthusiasts, who will appreciate not only the performance gains and added reliability, but also the more attractive pricing.”

Samsung says that the MLC SSDs will use a 3 Gbps interface and that the 128GB uses 64 MLC NAND flash memory chips of 16 gigabits each and is enclosed in a brushed metallic casing measuring 100mm x 69.8mm and 9.5mm thick. Samsung declined to comment on the pricing of the SSDs.

Samsung first announced the 128GB MLC SSD in January and it is just now entering mass production.

Perhaps you do not understand SSDs.

Access timings are all across the board. Not slower in some places and faster in others. This means that you will have a constant 90mb/s speed. This isn't really the fastest SSD I've seen. I've seen one on newegg, I've been eying for months that is a 30GB Super Talent MLC for $235 (Was at $300 2 months ago) and it's speeds are 140mb/s max read speed and 40mb/s max write speed.

I've had my Eee 4G Surf for 6 months on a Windows installation, and there is no slow down. It boots up in 15 seconds, it shuts down in 5-10 depending on how many programs I have open. The quality of the read/write speeds have not decreased like many will experience with traditional hard drives as they fill them up and get super fragmented.

To really get an understanding of max read/write speeds and why it's not going to be that all the time: You don't always need the max read/write speed, and a like, if you have other programs running, they're going to use up some of that read/write speed too. So one program may be using up 30mb/s read speed, and thus if you were to use HDtune to figure out what your average read speed is, it may make it say 60mb/s.

Just my two cents.

Access time and read speed are not related. Access time is how long it takes for the drive to find the bit of data and get ready to move it. Read speed is how fast the data comes out of the hard drive once the data has been found. Furthermore, there are really 4x types of read and write speed - random read, sequential read, random write, and sequential write, and those are all different. If you do some actual testing you will see that SSDs are very fast at small, random reads but often much worse that traditional hard drives at most other types of data transfer. Thus, the decision on whether an SSD is a good choice for your PC should be made based on what type of drive use you do. Lots of web surfing and office use? An SSD might not be a bad choice. Video editing? Bad choice. Video capture? Horrible, horrible choice. Basically, if you end up moving large blocks of data, especially writing large blocks of data, stay away from SSDs.
