A-Data S511 240GB review


The SandForce 2281 controller is faster than ever in this SSD

Revised controller ; Quickest read times ; Competitive price

Uncompetitive writes

Hello, A-Data S511. What's that? You can read and write at over 500 MB/s? Why, that's quicker than a spelling bee champion on MDMA. In fact, in both synthetic and real-world benchmarks, this solid state drive (SSD) is quicker than OCZ's similarly...

ADATA S511 240GB SSD Review (Sandforce 2281)


Solid State Drives are selling well in 2011, with a growing percentage of enthusiast users adopting one as a fast, primary boot drive. A few weeks ago we reviewed the OCZ Vertex 3 240GB drive, and today we will compare it against the ADATA S511 240GB,...

slightly less expensive than the Vertex 3 ; class leading performance ; IOPS results are better than Vertex 3

none we can see, but many will opt for the less expensive 128GB or 60GB version

Kitguru says: A strong challenger for the OCZ Vertex 3, and very closely matched.

ADATA S511 SSD Review


All SSD drives have one thing in common, speed. And lots of it. These little lightweights are the superchargers that will boost whatever OS it is that you are using. That's all sounds very good, but good things do come at a cost, and SSD drives have...

hybrid drive at around $180 if storage is important to you.

ADATA S511 240 GB Solid State Drive Review


The market is full of versatile SSDs on second-generation SandForce controllers. However, they are not the same. Let's see how the flagship ADATA product stands out among many other alternatives.

ADATA S511 240GB Solid State Drive Review


ADATA is now shipping their SandForce SF-2281 based drives. The new S511s are faster than the S501s and bring SATA III performance up to 550MB/s.

ADATA S511 240GB


When we first tested the Vertex 3 the BSOD and disconnect issues were annoying, and although OCZ was able to ease their frequency it was still a major issue for the product and those like it.

Update to previous review


I found out the answer to my own question after being ignored by adata... If you run these in RAID to update firmware take the drives out of raid the easiest way is to take them out and put in another pc to update the firmware with the program found on...


Adata! I originally had no problems with the drives and posted a positive review. However, I have started getting the blue screens that others have mentioned. I emailed adata tech support and have had no response.... They do not seem to back up their...

Working - and FAST


Since it already had the 3.2 firmware, stability isn't an issue. The firmware reported didn't change, though that may be an issue with them not updating the version number with 3.3.2. I can definitely see why some people aren't particularly comfortable...

Installed Win 7 in around 6 minutes. This thing is FAST

The firmware update tool isn't particularly informative on the results. Trying to update it in my old rig, I got a red x, without any further info. Even when it works, it doesn't really report success other than showing a green check mark
