In addition to Western Digitals launch of its consumer-oriented SiliconEdge Blue SSDs, the storage company yesterday also announced the solid-state solution for industrial uses.
WD calls it the SiliconDrive N1x, a 2.5-inch SSD that uses single-level cell (SLC) memory. The N1x SSDs feature a native SATA 3Gb/s interface with target read speeds up to 240MB/s and write transfer rates up to 140MB/s.
What's interesting to note is that WD today also launched the consumer-oriented SiliconEdge Blue SSDs, which have read speeds up to 250MB/s and write transfer rates up to 170MB/s. The difference, of course, is that the industrial N1x uses SLC while the SiliconEdge Blue models use MLC, making them not as well suited to data-intensive applications.
That point is observed on WD's estimates for operational lifespan for both drives. WD estimates that the N1x would go through a write cycle of 701.4GB per day, while the consumer SiliconEdge Blue drive would do less than a tenth of that at 70GB per day. Both drives carry the same MTBF of 1,400,000 hours.
As an OEM product, WD did not reveal pricing, but does list models of up to 128GB in capacity.

Not so sure about that, it's really conservative measure! And where did they get the 1.4GB? For credibility??
competition is good for prices in the ssd market, which we needReply
Yes,More competition hopefully it will bring the cost down. What happen to Sata III 6gs SSD.Reply

Wild guess: they took the SLC chips' rewrite numbers and the same MTBF of 1,400,000 hours figure then divided and converted into days...
If memory serves, SLC flash drives are supposed to be about 50% faster at writes and 10 times more durable to rewrites so those figures don't sound farfetched at all.
Too Bad, I can't afford it
Nice, too bad there's one problem. Weren't SLC drives supposed to be faster?Reply
Why is one of the largest HD makers in the world making boring SSDs? these would have been competitive before the OCZ Vertex and Intel X25-M/E drives came out, but now, they are middle of the pack at best.
WD... get off your butt and do something. Impress us.
Far too expensive compared to competition.
Low end performance.
Not worth the time.
Will probably have similar bugs to the X25E at launch.
When are prices expected to drop significally? What are the manufacturing costs for SSDs, anyone?Reply
darn! Our company has a write cycle of 701.42GB per day. We'll be having a board meeting on Monday do discuss if we can deal with the 0.02GB excessReply
