Samsung refreshes 64GB SSD with faster SATA II interface

Solid-state drives (SSDs) are the new hype in high-speed storage solutions and with each new launch comes improvements over the last. Currently, storage space is what many manufacturers are focusing on due to the demand by consumers.

There are still a few details that certain manufacturers are bringing up to speed. Many of the key players in the SSD game are still implementing a PATA interface on their solid-state products which is holding these devices back from performing at the highest levels. This is the reason for Samsung Electronics' most recent launch announcement.

Samsung announced in a press release that its 1.8-inch and 2.5-inch 64GB SSD with a SATA II interface is now in the mass production stage. The new SATA II version of the drive was announced in Q4 2007 and is said to remove the bottlenecks of the PATA interface used in the previous version of the drive.

According to the director of Samsung Semiconductor's flash marketing department, “While there will always be a market for HDDs, we see growing demand for our new SSDs, especially now that they are available with the SATA II interface.”

Due to the inclusion of the SATA II interface on the new refresh, transfer rates on the new 64GB SATA II SSD will increase 60 percent from SATA I versions of the same drive. Instead of the 65 MB/sec read and 45 MB/sec write speeds of the previous PATA SSD drive, the SATA II flavor will produce a maximum write speed of 120 MB/sec read and 100 MB/sec write speeds.

Additionally, because the drive is based on solid-state memory technology, the 64GB SATA II SSD will be able to withstand 1500Gs of shock within a 1/2 ms span, roughly 3 times the amount of shock a traditional hard disk drive would be able to withstand in 2 ms.

Pricing information on the 1.8-inch 64GB SSD is not officially available since these drives are currently an OEM-only option, however, it seems that PC makers such as Dell and Alienware are providing solid-state drives as a $1,000+ option in certain high-end notebook systems.

Recently, Samsung also announced a 128GB SSD using multi-level cell NAND flash which is scheduled for a mid-2008 launch with costs speculated to be around the $2,000 mark. With prices this high, only the super-enthusiasts will opt for these products.

That said, drives such as BitMICROs 832GB SSD that is scheduled for a H2 2008 launch will be completely out of reach for anyone but the mildly wealthy under current price schedules.

1500Gs of shock

I guess I don't know much about shock force strength, but 1500Gs of shock sounds like it would flatten a car or completely shatter that drive.

Basically, your SSD would last longer than any other component in your laptop. Which is awesome.

I'd like to see someone try and recover their SSD from a vehicle thats been hit by 1500G's of shock....

Someone gets shot in the back... but the SSD drive in the laptop in the backpack got hit... it's saved his life! What a miracle. And it's still working!

You'd be surprised how high of an amplitude of shock you can get by tapping a coin (or an accelerometer) against a hard surface, 1500 G's isn't anything at all in that case because the duration is so short.

What really matters when you're talking about shock testing is the total energy involved (area under the curve), that's why the data sheets always quote the amplitude as well as the duration.

A 1500 G, 0.5 mS, half-Sine shock pulse is a completely different animal than a 500 G, 2 mS pulse.

To compare against a car crashing into, say, a brick wall, you'd need to know the duration of the impact, which should be significantly longer than 0.5 ~ 2 mS.

I don't know that much about physics, and frankly I don't care unless my SSD is involved, or I'm falling and trying to calculate my odds of survival; but I recall reading something about when you jump you land with a downward force 10X your weight or something. So a 200lb person could exude 2,000lbs of downward force or something, which seems like a lot if you're jumping on someone else. Makes you wonder why there aren't more deaths in the NFL.
