Samsung rolls out its highest capacity 1.8" flash SSD

Back in March, Samsung announced its 64GB flash Solid State Disk (SSD). The 1.8" unit promised read speeds of 65MB/sec and write speeds of 45MB/sec.

Samsung today revealed that it has started mass production of its new drive. The 64GB SSD uses 64 eight gigabit single-level cell (SLC) flash memory chips which are built on a 51 nanometer manufacturing process.

"We see sharply increasing interest in SSDs among OEMs worldwide amid a growing push to launch premium SSD-based notebooks, particularly in the ultra-mobile category," said Jim Elliott, director, flash marketing, Samsung Semiconductor, Inc.

Samsung's 64GB SSD will likely appear at online retailers and inside ultra-portable notebooks (and UMPCs) within the coming weeks and months.

SSDs have the advantage of low power consumption, low weight, durability, silent operation and high performance. These advantages are expected to allow SSDs to account for 29 percent of ultra-portable notebooks and 25 percent of mainstream notebooks according to iSuppli.

The benefits afforded by SSDs are offset by one major deficit: pricing. 1.8" SSD are currently around five times more expensive than their 1.8" HDD counterparts. By the year 2010, that differential is expected to only drop to three times as expensive.

For those that simply can’t wait for the 1.8” 64GB SSDs to arrive, the older and slower 32GB version (53MB/sec reads, 30MB/sec writes) is available online for the princely sum of $529.

Something seems ironic to me about expressing concerns about the reliability of a solid-state drive and saying they are going to stick with their electro-mechanical drives.


Actually, the ironic part is that he's running RAID 0 and talking about reliability.

The other interesting point is that he's comparing RAID 0 with an SSD. He obviously has no clue what the differences between RAID 0 and an SSD are.

RAID 0 does nothing but allow for increased sustained sequential reads and writes of large files. At the same time, access speeds worsen. Small file transfers can also be slower than with a single drive.

SSDs generally have lower or similar read/write speeds compared to mechanical hard drives while having much lower access times. It doesn't take nearly as long to reach the information off the drive. For accessing files like those your OS uses, it's much faster.

Throughput is rarely a bottleneck except when reading or writing large numbers of smaller files or single large files.

Other than updates and pagefiles, most OSes and programs do not do much writing after initial installation and reads do not appreciably affect SSDs. Writes are what can "wear" out an SSD.

Also, SSDs have leveling implemented to spread out the writes over as much of the drive as possible to lengthen the life of the drive. As long as you aren't writing and erasing the same sectors constantly, the drive will have a long life. While I'm not a fan of MTBF ratings, most SSDs have an MTBF rating much higher than mechanical hard drives from what I've read.

I'd love to get my hands on a 64 gig SSD for an OS drive. At this time, there is no way I'm going to be forking out the money they cost, though. For me, the price is way too high for the advantages it has. Then again, I would pay a price premium for a good SSD over something like a WD Raptor since I see the SSD with more positives than the Raptor.
