ADATA S511 240GB SSD Review (Sandforce 2281)

As our sample was just out of the production factory, we don't have any retail packaging. ADATA did tell us that the retail package will contain backup and restoration software and a 3.5 drive bay mount.

Using a very high powered flash (above) it is easier to see the anodised aluminum style finish to the drive chassis. It is opened by removing four small screws on the rear. Please be aware if you do this, you invalidate the warranty. We don’t really care, but if you buy one, you should.

The unit we are reviewing today is the 240GB model, although ADATA are releasing 120GB and 60GB versions as well. ADATA have placed a NAND partition of 16 ICs onto the PCB. Technically, new 25nm NAND FLASH memory has a reduced overall lifespan from 10,000 upwards to around 5,000 program/erase cycles. Industry insiders have hinted that consumer grade 25nm NAND flash memory will have a slightly lower lifespan, between 3,000 and 4,000 program/erase cycles.

While this sounds concerning, if you work out that under normal conditions only between 20-35 full SSD write cycles will be used each year, there is plenty of life in the product. Drive wearing protection also helps to ensure longer lasting flash memory. Thankfully, there is also full TRIM support.

As many already know Sandforce controllers use real time compression. The controllers store a ‘representation’ of your data, not the actual data itself which is achieved by creating a partition of the available NAND flash memory. It can handle around 63 MB/s from one of the eight available channels.

  1. Excellent, these guys seem to be on the ball.

  2. A 60gb version is coming? Count me in for a couple of those puppies

  3. This controller is the future of ssd in the next year or two. Amazing speeds…

  4. Price is good. How much will the 60gb version be?

  5. Based on pricing of 240gb. I would say 60gb will be around 110 to 120 pounds

  6. The 60GB appeals to me, ill probably get 4 for QUAD Raid 0 performance. Should only be around £500. much better than a single 240GB drive. Any chance of a test Zardon of this setup?

  7. ADATA seem to be bringing more cool stuff out lately. I dont often see them on stores I use however, which is concerning.

  8. What are the warranty terms on their SSDs? in UK, and also how do we return them if they fail. to their HQ or to the dealer we bought from? I got burned on Patriot before. moer info would help

  9. Im still not convinced to just jump in with ADATA, but they are on my radar now, they weren’t a few months ago. This drive looks really good, I also like their tweaks on this drive, it looks like they put a lot of effort into the tuning

  10. Very good drive, aggressive pricing too.

  11. The 240gb is very nice, but its a hell of a lot of money for a drive. 120gb is more sensible, but I can see them selling a ton of 60gb units.

    erm.. why aren’t OCZ selling anything smaller than 120gb? whats up with that?

  12. very nice indeed, shame it cant be bought anywhere yet. 60GB might be a good boot option

  13. They certainly have the pricing right, never heard of the company however !
