I wouldn't call JMicrons chip popular. Infamous is a more appropriate term.

1GB of cache, that's quite a bit.

"And to top that all off, the onboard SSD controller is also built by Samsung – a bold move, considered by some. For comparison, Intel uses a Promise made SSD controller and OCZ makes use of the popular JMicron controller chip."

Your information is out of date, read the anadtech SSD anthology article.

In the article, the cache is described as one Gb, not one GB.

They don't anymore, do they? I know their Summit series has the sammy chip as well and the vertex has the Indilinx chip.

spazoidIn the article, the cache is described as one Gb, not one GB.

"This 256 GB SDD consists of sixteen K9MDGZ8U5M-SCK0 Multi-Layer Cell (MLC) flash chips along with a 1 GB K4X1G323PD-8GC6 DDR cache chip."
notice the capitalized GB

Yes, that is my point. The original article states "1 Gb" and the THG recap interprets this as "1 GB". Which statement is the correct one, I do not know, but if it is indeed a 1 Gbyte (8 Gb) cache, then I must say it is very impressive.

I've only seen the little "b" intentionally used to indicated bit in bandwidth, not storage size. But then I haven't seen everything everywhere forever.

1 GB (gigabyte) is quite likely.

Purchased this drive about 3 weeks ago and have been running it in my Macbook pro. I've put a brief review of it on my site including launch/shutdown timings for both the apps and the laptop.

The cache memory chip is described as 1 gigabit on the samsung website which means that it is indeed 128megabyte... The corsair is therefore identical to the Samsung.
