Final words and conclusion

 

Final words and conclusion

ADATA really has a good SSD in their hands with the the SX900 series. We really are a little surprised though that after everything that has happened with the SandForce 2200 series controllers and their firmware issues that ADATA actually pursued this controller as a basis for their most high performing product.

The past year Sandforce 2281 based product have been plagued with firmware issues, the SSD would spontaneously drop themselves from the storage array, or sleep mode related bugs made the SSDs system crash. It was weird to see and witness. Though we always have had a hard time replicating the issues ourselves, a lot of our readers did run into them. As such it is only fair to mention this. Please know that its all fixed in the newest firmwares, I'd honestly have no problem using a 2281 based product myself, I'll even step it up a notch, most of our tests systems are equipped with one -- but the reputation damage is done and all costumers flee to Indilinx and Marvel controller based product, just to be save.

Being SandForce 2281 based the peak read and write performance on this product will be a notch higher when you compare it to Marvel and Indilinx based product. When you focus purely at IOPS performance, well that's where an SSD like this is a winner, hands down.

The big question remains, and its totally up to you, if you still, trust SandForce 2200 series based products. Again, know that the initial bugs have been found, squashed and eliminated. The SandForce controllers are stable and it shouldn't be a reason to "not" get one. But storage is all about reliability, and if that reputation is dented... well it might be until the next generation until people will regain that trust. Data integrity means the world to us, you can't forfeit on that -- period.

ADATA SX900

An SSD is enjoyable, very much so. If you put a drive like this into your SATA 3 compatible laptop or SATA 3 compatible PC, you'll have no idea what is about to hit you. We very much enjoy the grand sustained performance of this SSD series, so you you copy a fast amount of compressed data, then the Series 520 will slay and slaughter in performance.

SATA ControllersSome overall recommendations then. Should you be in the market for a SATA 3 SSD then we have a couple of hints though, we absolutely prefer the performance of the Intel Series 6 or 7 (H67/P67/Z68/X79/H77/Z77) integrated SATA 6G controller over anything else available in the market. If you run an AMD chipset with the added Marvell 6G controller for example, you will see lower performance.

The new Asmedia controllers we spotted lately on motherboards are also offering good performance, albeit still 20%~25% slower then Intel's controllers. Also make sure you run your drive in AHCI mode, it does make such a difference in performance -- really guys, a big difference.

Prices HDD versus SSD
My advice is simple and I'll keep repeating this in each and every SSD conclusion; you probably should stop looking at the Solid State Disk technology as if it were a traditional HDD. We all will be old and grey before the two reach the same prices or top the multiple TB volume storage the HDD offers for less money. Comparing an SSD with an HDD is making a comparison in-between an integrated IGP or a dedicated graphics card, that last one will cost you a heck of a lot more yet you gain incredible overall performance. It is the very same with an SSD, use it as boot drive on Windows and applications and you instantly have removed a huge bottleneck, namely load and access times. It is a difference in-between night and day (in a proper system). For massive storage like movies, MP3 files and bulky data you do not access on a regular basis, sure that's where the HDD remains the winner as a cheaper storage solution.

The magic simply is finding a good combination in-between the two and balance things out. That's where the magic happens. I kid you not, all my test systems and work systems run on SSDs, not once have I considered going back to HDDs. The benefits of a good SSD are simply grand. But that doesn't mean I do not understand the budget and cost dilemma that many of you are facing though. There are still many variables and unknowns regarding life-span.

Concludingguru3d-recommended_150px.jpg
The ADATA Series SX900 SSD 256GB model as tested today is an extremely very fast and high performing product, it's a tiny bit late to a very crowded SandForce 2281 market though. ADATA did it right, the latest optimized firmware, the synchronous memory, the slightly bigger SSD sized thanks to a cut off in NAND provisioning and then the SF2281 simply hauls the proverbial toosh in sheer performance.

Interesting to see is that it is the first SSD that I know of to forfeit on over provisioning  (7% of the flash NAND typically) as we have become accustomed to.

To keep the good spirit, ADATA will cover this product with a three year warranty. Let me wrap it up, I have every confidence in the stability and extreme performance of the SF2281 SX900 based products, and as such I wouldn't hesitate using an SSD like shown today. It is a powerhouse in terms of storage performance and as such comes recommended.
