Pros: I purchased this drive in January but used it very little until recently. It was then I discovered that although I had purchased the 128 GB model, and the drive I received did say 128 GB on the case, it was actually the 32 GB version. Perhaps mine was made at the end of a run and got installed in the wrong case.

I wish to give Newegg a very positive shout-out here. When I brought the error (not their fault) to their attention they FedEx’ed me the 128 GB version and told me to just keep the 32 GB drive. Outstanding customer service.

On with the review:

I also have an ADATA 128 GB flash drive and since the Silicon Power was in the same price range, I thought I would run benchmarks to see if either was better than the other. Both of these drives fall into the “value” category rather than the high performance category (good for the money, but not anywhere near the performance of, say, the SanDisk 128 GB Extreme model – which is about double the price).

The outcome was very interesting, and unexpected.

Using ATTO benchmarking software, the SP recorded 157 MB/s Sequential Read and 99 MB/s Sequential Write.

The ADATA recorded 111 MB/s Sequential Read and 116 MB/s Sequential Write (unusual for the Write speed to be higher than the Read speed).

Since I was mostly interested in the Write speed, it appeared the ADATA was slightly the better choice.

However, when I actually began transferring files, the SP beat the ADATA every time, and by quite substantial margins.

So, using DiskBench software (a free download), I measured the actual transfer time and transfer rate (in MB/s) it took to transfer various files sizes (both drives empty and formatted to NTSF).

As it turned out, irrespective of the ATTO Sequential benchmarks, the Silicon Power 128 GB tested far better on file transfers of 4, 8 and 12 GBs. The average transfer rate for the SP was 67.1 MB/s vs. 35.27 for the ADATA – the SP was an amazing 47.4% faster. In one case, this resulted in a 1 ½ minute faster transfer time for the SP.

So, performance wise, the Silicon Power 128 GB flash drive appears to be a much better value.

(If you are interested in an even better “value” drive, the HP 128 GB model 702 – made by PNY -- was able to maintain an average transfer rate of 104.8 MB/s and is only about $10.00 more. That is 36% faster than the SP.)

The Silicon Power 128 GB flash drive is highly recommended in its price range.

Cons: Minor: The case is not as substantial/solid feeling as the ADATA but is not flimsy, either.

Other Thoughts: Both the Silicon Power and ADATA drives come with lifetime warranties.

Pros: On sale for $44 CAD with shipping and tax included.
Just received item and tested it with a 3.0 USB port.
read: 129 Mb/s
write: 72 Mb/s

Black casing, red LED indicator for read/write operations.

Retractable USB tip.

Cons: None

Other Thoughts: Definitely a recommended product from me.

If I needed another 128 GB flash drive I would not hesitate to buy another one if this were on sale again.

Pros: Cheap Price for capacity and speed

Cons: Unreliable drive. Keeps ejecting on it's own no matter what computer I use it with. Horrible Product.

Other Thoughts: Returning it and getting a well respected name brand instead. You get what you pay for works here...!

Pros: Fast and an excellent price. 3.0 transfer speeds are good (70-90Mbps) from my SSD drive to this thumbdrive.

Cons: I purchased 4 of them and not one issue with any of them.
The only thing i dislike if i had to pick is that sliding mechanism isn't smooth, rough pushing up and down, but not something that is a problem really, its just the only thing i can pick.

Other Thoughts: It would be nice to have a strap or something with it, i think any USB drive that's sold should have one.

Pros: -For the price and size, you cant beat it.
-Fast read and write speeds.
-Very firm when inserting into a USB for a retractable drive.
-Sleek design, smaller than expected.

Cons:
-Died after 5 weeks.
-During long transfers the drive does get hot to the touch.

Other Thoughts: The drive died after 5 weeks. I used the drive 1 to 2 times a week and it had over 100GB of data. I was able to successfully recover the data but none of the data was too critical. I will replace this drive with the same one and give it another shot. The price, speed, and the size (physical and internal) really sold me. Very impressed aside from the quick failure.

Pros: Inexpensive, capless, good warranty

Cons: During BitLocker encoding, ran too hot to touch. Gave a whole new meaning to the term "burn-in". After encoding, I copied 45 GB of large video clips on the drive - average write speed was 9.81 MB/s. Had to use my laptop cooler to keep the temperature manageable.

Other Thoughts: It isn't really a USB 3 drive.

Pros: - Cheap
- Lots of memory

Cons: - Plain looking

Other Thoughts: - Going to buy another one

Pros: Works fine.

Cons: Its plastic and without a way to put on a key chain.

Pros: -cheap, big, fast.
-solid construction.

Cons: -no lanyard or chain.

Other Thoughts: -35 mbs write 35 mbs read on 2.0 port
-120 write 90 read on 3.0

Pros: - good price
- fast read speed (+100mb/sec)

Cons: - slow write speed (~20mb/sec)
- no strap included

Other Thoughts: drive comes preformatted to fat32 with some files that you can register for a warranty with.
