ADATA XPG SX900 (128GB) Review: Maximizing SandForce Capacity
by Kristian Vättö on June 8, 2012 1:25 AM ESTAnandTech Storage Bench 2011—Light Workload
Our new light workload actually has more write operations than read operations. The split is as follows: 372,630 reads and 459,709 writes. The relatively close read/write ratio does better mimic a typical light workload (although even lighter workloads would be far more read centric). The I/O breakdown is similar to the heavy workload at small IOs, however you'll notice that there are far fewer large IO transfers:
| AnandTech Storage Bench 2011—Light Workload IO Breakdown | ||||
| IO Size | % of Total | |||
| 4KB | 27% | |||
| 16KB | 8% | |||
| 32KB | 6% | |||
| 64KB | 5% | |||
The difference in performance between the SX900 and S511 might seem bigger in our Light Suite, but in terms of percentages it's about the same (the SX900 is 7% faster in our Heavy Suite and 8.7% faster in our Light Suite). Overall performance for the SX900 continues to be similar to other 120/128GB SF-2281 based drives, with firmware and NAND differences causing minor differences in raw performance. In practice, most home users would be hard pressed to notice the difference between the fastest and slowest of these SSDs in day-to-day use.

If you're going to put Mushkin up there, you might as well put OWC there too. Their drives seem to perform fairly well and are priced "decent"Kristian Vättö - Friday, June 8, 2012 - link
I only put Mushkin there because many have been asking for that since it appears to be one of the cheapest brands. OWC is not cheap, in fact even Vertex 3 is cheaper except the 480GB model. The table is endless if I start putting every brand there, plus checking the prices is PITA and already takes a decent amount of time.StevoLincolnite - Friday, June 8, 2012 - link
Plus... Only 4.52% of the worlds population resides in the USA, so the prices are pretty much useless for the 95.48% of the Earths population that doesn't reside in the US.StevoLincolnite - Friday, June 8, 2012 - link
To add to that, I don't mean to belittle your efforts, I just don't bother to look at the pricing on this site.jak3676 - Friday, June 8, 2012 - link
% of world population is hardly a useful stat to toss out there - you could make a decent argument with % of SSD's sold by country/region, but lets face it 99.99% of the world population (to include the US) isn't buying SSDs.If he listed prices in Euro or CAD or Yen or anything else he'd just be favoring that market (which is probably smaller than the US market anyway). Even if he could list prices available by country for the top 10 markets, he'd just turn off all of us as people wouldn't want to scroll through 10x the number of charts.

4.52% of the world's population, but 22% of the world's GDP. That's why US prices matter.JarredWalton - Friday, June 8, 2012 - link
And let's not forget that our site's primary readership *is* in the USA. I'm not sure of the breakdown, but I'd guess close to half of all our traffic is US based. Even if it's only 1/3 (Kristian for example is based in Finland), I doubt there's any other currency where our listing SSD prices in that denomination would prove more useful to our readers.Jaybus - Friday, June 8, 2012 - link
Yes, but some two thirds of international trades are in US dollars and it is still the de facto exchange currency.Anyway, what difference does it make? The point is relative prices between drives from different manufacturers. I don't think the ratios would change for different currencies.

You realize this is a US based website right? and that the majority of the readership is based in the US?Go to a website that caters to your country's currency if this is a problem for you.

Useless? Speak for yourself, some of us in the 95.48% know how to do currency conversion.Are you also going to claim the USD prices of oil, gold, silver, CPUs, DRAMs, etc are useless to the rest of the world?
There's plenty of stuff in the world that are priced in US dollars - as in the manufacturer's/producer's main selling price for the item is in US dollars. And the price in other countries is linked to that USD price. When the USD price goes up, their prices go up too.
If the petrodollar loses its hold (its slipping a bit) then it might make sense to use some other currency. That'll be bad for the USA as the US Gov will no longer be able "tax" other countries just by creating more US dollars.
