fast read and transfer rate for a usb 3.0 flash drive

Some years back before I had USB 3.0 capability I purchased a Patriot 128GB Blitz USB 3.0 128GB Blitz Flash Drive. Don't recall if I checked the read/ write at the time or if I read reviews. Besides it said "Blitz" and it was a fancy racing yellow color. Turns out a short time late when I got a machine with USB 3.0 capability this drive was a complete dud. Slower than most of my USB 2.0 flash drives still now chugging away. Now the Blitz no longer works in any USB 3.0 port and only USB 2.0 ports. Any recommendations for a FAST read/ write cost conscious run of the mill USB 3.0 flash drive? I came across this page. Comments welcome. Thank you.

A USB 3.x flash disk can have fast communication electronics but a slow memory write.
I have never seen a USB 3.0 flash disk that Read is faster than 480 Mb/s or 60 MB/s (USB 2.0). Write speed is much slower than that. So Read / write speed is the same on a USB 2.0 port or USB 3.x port.

The USB 2.0 connectors (male and female) has contacts on only one side
The USB 3.x connectors (male and female) has contacts on both sides (up and down). If you connect a USB 2.0 device it will use only one side. If you connect a USB 3.x device it will use both sides.
USB - Wikipedia

If the Blitz no longer works in any USB 3.0 port and only USB 2.0 ports you may have some bended contacts.

There is a lot of variation among USB 3.0 flash drives. Some are at least 5 times as fast as others.

I haven't done any research in the last few months, but a year or so ago, the Sandisk "Extreme" models were quite fast compared to others I own.

Note: for many uses, you are better off buying a full size 2.5 inch SSD. You can get a Crucial 120 GB SSD for 20 bucks today at Newegg.

Here are some comments I noted in a Word doc:

32 GB SanDisk Extreme from WD Green 3.0 TB, drag and drop 13.8 GB (38,640 files) through rear USB 3.0 port on Antec Solo case; 14.1 minutes; aka 58.7 gigs per hour. Average file size 357k; 845 seconds; about 16.3 mbs; copied same files back to Samsung internal in 7.2 minutes, so apparently reads are almost twice as fast as writes.

Same drive and same tests when attached to a USB 2.0 port yielded speeds about 70% of the above.

Copying 57.5 GB (14,563 songs) of mp3s from Samsung 1 TB to Kingston Data Traveler Micro DTMCK 64 GB 2.0 USB thumb drive for car through USB port on front of Antec Solo II case: Took 267 minutes when using 16384 byte allocation units rather than the default 32768 bytes. This is 12.9 gigs per hour.

Copying from the same 64 GB Kingston USB drive to Samsung 7200 rpm hard drive: 14137 mp3s (55.1 GB) in 58 minutes; about 15.6 mps, close to 4 times as fast as writing to the same USB drive. This is 57 gigs per hour.

Thanks for the input. As noted the BLITZ has been a piece of sh@it since day one and I am just looking to replace it with something else.

Thanks for the input. While I have an open slot for a PCIE m.2 SSD I want portability and I do not want to purchase an external enclosure for the SSD. Yeah, I have had mostly good luck with SANDISK. Should have mentioned that I am looking for a 128GB USB 3.0 flash drive. Hoping I get some more specific happy customer recommendations before slogging threw the Internet. Thanks.

The prices are high. I would buy a 2.5" SSD and attach it to a USB 3.0 case.

You don't need an enclosure. You can get portability with something like this, for $23.

It's just a cable adapter with its own power supply. Allows you to attach any standard SSD or HDD to a USB port on a PC, where it will function just like a flash drive.

Or this if you don't need a power supply, for $7:

I still use flash drives, but am always a bit spooked by their fragility and am not enthused by their speed, so I've probably bought my last one.

I paid $65 for a slowish Sandisk miniature 256 GB flash drive in April 2018. That was a something of a bargain at the time.

Today, name brand 2.5 inch SSDs at Newegg:

Crucial BX500 120: 20 bucks

WD Green 120; 28

Crucial BX500 240; 29

WD Green 240; 40

Crucial MX500 250; 40

Intel 545s 256; 44

You can get 500 GB for 60 bucks or less.

Thanks! Those are pretty good suggestions:

1. Sabrent USB 3.0 TO SATA/IDE 2.5/3.5/5.25-INCH Hard Drive Converter With Power Supply & LED Activity Lights [4TB Support] (USB-DSC9)

Never heard of Sabrent before though that is mostly irrelevant. A cursory look did not show read/ write or bottleneck problems so I'll have to look closer. Still leaning however towards the simplicity of a simple flash drive.

2. USB 3.0 SATA III Hard Drive Adapter Cable for 2.5 inch SSD & HDD Support UASP 20 inch, Black …

Never heard of UASP before either and something about it gives me pause:

USB 3.0 UASP Mode - Performance Benefit or Marketing Gimmick

3. "I paid $65 for a slowish Sandisk miniature 256 GB flash drive in April 2018. That was a something of a bargain at the time"

I'll keep your suggestions in mind though for the time being I am still stuck in "stick it in, pull it out" flash drive mode : )
