Over the next few days I will try to gather as much information as I can on the new Marvell SATA 6G controller used in the A-DATA S501. It is still too early to start talking about awards, pricing or even availability.
When it comes to the performance of the A-DATA S501, we can already see that the drive is capable of some very impressive results in the synthetic tests, but the real world results are still a bit on the low side. When we tested the RunCore Pro V at CES this past January we were told the drive was ready to go; just wrap it in a retail package and the two would match up. We later learned that this was not the case.
A-DATA hasn't said just how far they are out on the S501, but we are guessing the final stages will be completed very soon. Given the amount of performance increased with the RunCore Pro V from early to final production, I think the S501 deserves a chance to get finished before we really jump to conclusions on the final real world performance.
So there you have it, early synthetic and real world numbers on a pre-production A-DATA S501 128GB SSD. We are very excited to see results that we achieved today even though the performance will change a bit between now and the retail product. It would be pretty difficult to imagine A-DATA going the wrong direction with final product performance.
I am glad to see the 140MB/s write speed limit erased on a Marvell controlled SATA 6G 128GB drive and really, what all do I need to say other than just giving you the read speed results. At right around 400MB/s sequential read, this is highest performance we have ever seen in this test from a single drive.
