Re: Asynchronous vs. Synchronous NAND Flash SSD Performance
Well, it is about 1:45AM CST, 12/22/2012 and all is well. Yet another "impending" apocalypse that fizzled, how many have I lived through in my lifetime?
Regarding this:
INTEL 330 180GB
NAND: Asynch(?)
Low Price: $89.95
High Price: $149.50
There is no chance the Intel 330 uses asynchronous NAND. The last time Intel used async NAND was in their G2 SSDs, like the X-25 M series, which used ONFI 1.0 Async NAND chips. They were introduced in July, 2009, the 80GB version cost ~$225.
I'm surprised that Async NAND is still manufactured, given the current ONFI standard of 2.0, and 3.0 will be seen in 2013. Perhaps it is used for other purposes. Any SSD manufacture using Async NAND today may be using NOS (New Old Stock) NAND, which I would think would be cheap. OTOH, prices of the older 34nm NAND chips was much higher than the newer 2Xnm chips, so you can find seemingly strange pricing on older SSDs, like the Intel 510, that currently is priced higher than Intel's 520 SSD, of the same capacity. Not many 510's left, and they are a discontinued product.
