What more can you say?
So far so good. Can never go wrong with an ssd drive. :)
By Gabriel Roy
Inexpensive but write speed was slower than expected
I bought this product due to all the positive reviews and relatively low cost for a 960gb ssd. I have owned ssd's from intel, pny, sandisk and samsung and they have all worked well for years. Therefore i figured this adata ssd should be somewhat similar to other ssd's i have owned. Benchmark results are inline with other reviewers have posted.But here comes the disappointment. In real world application, i wanted to back up a folder of document from an ssd to this new adata 960gb ssd. The folder has about 3,000 files with 35mb to 50mb for each file size. This simple copy takes about 20 minutes. But if i do the same with a samsung 840 pro the entire process took only 8 minutes. Obviously 840 pro is more expensive but i didn't expect the difference to be this big. With a samsung 850 evo and sandisk ssd's the same copy takes about 11 minutes. I ended up returning this ssd back to outletpc as the write speed is too far off.

Cool !

Look elsewhere.
Terrible. Sent it back after i found out that it will transfer at approx 450/450 mb/s for the first 260mb then the write speed drops to around 80 mb/s and never comes back until you stop copying and the process repeats. So it's fine if you only ever copy 260 mb at a time. Research sequential writes. I bought the mushkin 1 tb from newegg for $205 and it reads around the same but the sequential writes are about 4-5x faster then this drive.

Perfect upgrade to breathe new life into an old computer..
Fast, fast, fast! Fair upgraded my macbook pro with this, and wow what a difference! I would say a 10x performance increase compared to the feeble hdd.... Good purchase.

Using over 2 months with windows 10 pro as the c drive. No problems yet.

You get what you pay for.
Ok, i'm upping my score.I got a bad read-sector on one adata drive i got last year. Got another one a couple months ago and it's been perfect, w/ 500mb read/write rates every time. Rates on other one were the same, but some benchmarks dipped under 500mb (oh no! sarcasm)i've now had two ocz (one radeon 7) and another toshiba brand. One toshiba has died (it was doa essentially, kept cutting off every 10-20 seconds), the other radeon 7 ocz before toshiba bought them failed to the point the os wouldn't boot. And my adata didn't fail totally, it had a sector or two fail, which happened to be holding system files, but i rma'ed and they gave me the same drive back (i had marked the sectors bad, so after i did that and reformatted, it didn't reproduce, so i judge they fair gave me my feeble drive back (had a distinct scuff label that was there when i sent it in which was still there), which i didn't extremely appreciate. If a sector fails, i want a unique drive, even if it's fair one or two. Quick turn-around and i judge they paid the shipping - i work in it so it's hard to hold track of everything - and i'm getting older and my memories not as excellent as it was ;) i also have a samsung evo 850 1tb. This drive is fair as quick as both of them. Solid 450-500mb read/write rates. Acquire this before it sells out and don't believe the 3d hype, this 2d holds up, minus ~50mb/sec or so - which isn't even consistent, it sometimes benches fair as quick as the evo 850. Don't waste the extra 100 dollars, though i will say, it's the only brand, along w/ kingston, that has never died on me. Great drive over all.

Works incredible and the laptop speed is greatly improved.

They appear to be a good product at a very reasonable price
I have several of these ssds in external drives and in an older macbook pro. So far no problems. They appear to be a excellent product at a very reasonable price.
