Other Thoughts: In my previous review I noted that when Benchmarked, the Sequential Read and Write performance of this ADATA drive significantly exceeded the factory advertised specs.
However, after I began actually using this drive, I found that the transfer speed drops off **dramatically** after about 12 seconds when transferring large files.
I transferred about 20 GB of video files from my OS drive (a Samsung 950 Pro PCIe SSD) to the ADATA. For the first 10-12 seconds the transfer speed maintained a respectable 90-100 MB/s. But after that, it dropped off to very slow 10 MB/s and stayed near that speed for the remainder of the transfer.
So to reiterate what I said earlier, this is a great little storage drive to hold backup data. But it is very slow if you have to frequently transfer large amounts of data.
In fact, the 64 GB version did better. It was able to hold around 50 MB/s transfer speed for a 20 GB data transfer.
I think it's worth the $24.99 I paid on Black Friday, but in accord with its price, it is a lower performance drive.
Pros: I must say that I am impressed with this drive considering its price. I purchased it on Black Friday for $24.99.
Most of the budget priced USB 3.0 flash drives I have benchmarked either don’t meet their advertised specs, or don’t even give specs (the sure sign of a poorer performing drive). And many lower priced USB 3.0 flash drives perform only marginally better than USB 2.0 drives.
The advertised specs for this particular ADATA flash drive are: 90 MB/s Sequential Read speed and 40 MB/s Sequential Write.
Using ATTO Benchmark software I measured 112 MB/s Read and 116 MB/s Write (it is a bit unusual to measure a faster Write speed than Read). These speeds are on par with most of the 7200 RPM USB 3.0 external hard drives I have measured.
So this drive performed far better in both Read and Write than its advertised specs.
Furthermore, this drive was remarkably consistent in its performance. ATTO takes fifteen samples and once this drive hit 110 MB/s plus, the transfer rate stayed above that speed for the remaining seven samples.
I also own the 64 GB version of this drive and it too exceeded its advertised specs.
I have benchmarked drives that met their specs on one sample, but then fell off in performance after that.
Cons: The case has a lesser expensive feel to it, but does not appear to be flimsy (that’s to be expected at this price). The slide mechanism has a solid feel.
Other Thoughts: Although I prefer much faster drives for everyday use (such as the SanDisk Extreme series, or Kingston HyperX) this is a great little storage drive for the price. Highly recommended.READ FULL REVIEW
This review is from: SanDisk Extreme PRO 128GB USB 3.0 Flash Drive Model SDCZ88-128G-G46
Pros: On previous comments, I noted that I have purchased three of these drives and none of the three was able to break 200 MB/s on either Read or Write.
I returned all three.
But when Newegg ran them on sale for $59.99 -- and I had a $20.00 Newegg gift card -- I thought I would give it another try for $39.99.
This latest drive benchmarked (ATTO) at 267 MB/s Sequential Read, and 239 MB/s Sequential Write. That is to say, it met the advertised specs.
Cons: Not a con with this one, but that means the other three drives I returned -- that couldn't break 200 MB/s -- did have some valid problems.
Other Thoughts: I like SanDisk flash drives and own a number of the Extreme models in various capacities. Although there are a few others that benchmark slightly better, they are also significantly more expensive (the Lexar P-10 series, for example).
I think SanDisk represents the best value for the money.
