32 & 64GB. Inconsistent but fast enough for most jobs. Incorrect Amazon info (NO LED status light)
3 Stars
32 & 64GB. Inconsistent but fast enough for most jobs. Incorrect Amazon info (NO LED status light)
Update: Purchased a 2nd 64GB drive. Read speeds are ~4% better/faster, but write speeds are 20% worse/slower, compared to first 64GB drive purchased. Is that normal manufacturing variablity? I don't know, but am lowering my rating to 3.5 stars.Strangely or not, the new 64BG drive is formatted as exFat32, instead of old school FAT32 like the one I purchased a couple months ago. The only format options shown by Windows for this new 64GB drive are exFat32 or NTFS, although there are probably special programs that could format it as FAT32.Incorrect info (I reported to Amazon): These drive do NOT have an LED status light. I have 3 of them; no lights or LEDs whatsoever. Confirmed by official mfr website https://www.transcend-info.com/Products/No-610---Original review ~4 starsPurchased both a 32GB and a 64GB stick. Both are FAT32 format, which I have not changed. Actual storage size available is about 9% less than advertised (booo! but not unusual).No huge issues so far. Could definitely be faster (they are nowhere near theoretical max possible 3.0/3.1 speeds), but good enough for my purposes. Does not seem to get hot; just mildly warm after transferring a few files. For the price, I am mostly satisifed.TRANSFERRING LARGE FILES (movies):For the 32GB stick, copying (writing) a 611 MB movie (.mp4 format) from traditonal non-SSD hard drive to the stick took ~17 seconds. Transferring a larger 1.6 GB movie took ~45 seconds.TESTS: (see attached photo)I am no expert. I used free "USB Flash Benchmark" program, with the Transcend sticks in a powered USB 3.0 hub by Vantec ( https://www.amazon.com/gp/product/B07NX1NKXV/ ), and also plugged directly into 3.0 ports on back of a gaming PC (speeds were consistent with hub vs straight port).READ speeds for files 65 kB to 16 MB: 64 GB stick: ~ 120 MB/s 32 GB stick: ~ 140 MB/s (slightly better)WRITE speeds for files 64kB to 16 MB: 64 GB stick: ~ 29 to 65 MB/s 32 GB stick: ~ 29 to 80 MB/s (a wee bit better)Read & write speeds continue to drop with smaller files (below 64 KB size), which is usual for USB sticks.The 32 GB Transcend seems to perform up to 17% better than the 64 GB stick, at least for some larger file writes. Probably normal manufacturing/quality variance?

5.0 out of 5 stars This is one of the fastest 64GB drives I've seen, let alone one of the cheapest
Reviewed in the United Kingdom on March 3, 2021
Reviewing the 64GB version:

Nice quality and durable plastic case with what feels to be a solid retractable connector, has a nice feel to it.

There was lots of discussion about how it would be rubbish for a cheap stick so I didn't have high hopes but decided to CrystalDiskMark it to be sure - got 110MB/s read and 71MB/s write, which is vastly better than I would have expected for this kind of money (just over £5), even much more expensive sticks would struggle to reach this performance.

Doesn't get too hot in use (just a little warm) and no issues to speak of. Does seem to slow to around 25MB/s write after 2GB or so has been transferred but still consider that quite quick.

Highly recommended.
