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.

But at least include Mushkin in the benches, after all that's the cheapest SSD out there. This would give a better picture of $/performance.Kristian Vättö - Friday, June 8, 2012 - link
We don't have any Mushkin drives in our labs. I have asked Mushkin for a review sample but I have yet to receive a reply.CeriseCogburn - Monday, June 11, 2012 - link
I hate to say it but "good !" - that's what keeps their asynchonus prices so low. :-)Belard - Friday, June 8, 2012 - link
Considering the history and being a favorite, I think the Intel X25-M G2 120GB should be included in the benchmarks. So many of us can track the improvements and see if its a good time to upgrade or not.The G2 still does pretty good for its slow-interface, since its not a SF drive.

Bench also works :-)http://www.anandtech.com/bench/Product/605?vs=126

Thanks... Its still easy to forget that function is on the website.Assimilator87 - Friday, June 8, 2012 - link
There's no point in including more than two, MAYBE three SandForce drives. One with synchronous NAND, one with asynchronous, and the Intel cuz it has a different firmware. They're all the same hardware with a different sticker.iceman98343 - Friday, June 8, 2012 - link
when are you going to rereview vertex 4? new fw was released.UltraTech79 - Friday, June 8, 2012 - link
Where are you guys getting these numbers? One place? The suggested retail price? The 256GB M4 is going for $0.70 per GB at amazon.Kristian Vättö - Friday, June 8, 2012 - link
We used DynamiteDeals to hunt for best deals. However, the table is a bit outdated (the prices are from May 22nd). I know it should be more up-to-date, but the problem is that DynamiteDeals does not work for me as it's tied to one's IP address. Since I'm located in Finland, it only finds Finnish stores (well, there is only one it finds...). Jarred made the pricing table but in the end, Anand was the one who posted this article (it's been ready for ages, just needed Anand's final look at it).
