Bought three of these Samsung BAR plus in 64GB, two for key chain use, one to have handy on my desk. Made sure Amazon was the seller to help avoid any risk of non-genuine Samsung parts. Just arrived and burned each one in briefly using CrystalDiskMark, so I could both be sure each worked and compare speeds between the units. All three tested within about 2% of each other on each benchmark. Importantly, the sequential read speeds exceeded the claimed 200 MB/s in each case, averaging 224 MB/s. Writes were all 34MB/s. All tests were conducted on my laptop, a Lenovo Flex5, on a USB 3.0 port. Clearly the sequential read speeds take advantage of USB3.0 bandwidth.Overall very pleased for the price and the key chain friendly stainless steel casing. Note I did put a cover on the USB end of each, using the covers from Honbay 40pcs Semitransparent Black and Clear Plastic USB Male Anti-Dust Plug Stopper Cap Cover . I wanted just a bit more protection when used on key chains from dents and the elements. These Honbay covers fit snugly yet come off relatively easily. These feel like TPR, which is good for grip and flexibility.Pros+Fairly fast overall for the price, and clearly very fast at sequential reads.+Good looking, tough stainless steel body+Great form factor for handling - only as wide as a USB port so they won't cause any interference with adjacent ports, a bit longer than the really small USB drives designed to stay mounted all the time, but therefore very easy to get in and out, especially with the raised end near the lanyard hole providing a nice grip.+Hangs just fine on my key chain, a Maxpedition Gear Keyper Maxpedition Gear Keyper, Foliage Green using a FREEkey ring, the absolutely most secure rings you can buy in my experience FREEkey Accessory Ring Spares, 10 CountCons-wish for faster write speeds-gets warm but not so hot as to be a concern so farNo data yet on reliability, will updated if I find any issues.CrystalDiskMark results, below...-----------------------------------------------------------------------CrystalDiskMark 6.0.0 x64 (C) 2007-2017 hiyohiyoCrystal Dew World : https://crystalmark.info/-----------------------------------------------------------------------* MB/s = 1,000,000 bytes/s [SATA/600 = 600,000,000 bytes/s]* KB = 1000 bytes, KiB = 1024 bytesSequential Read (Q= 32,T= 1) : 224.198 MB/sSequential Write (Q= 32,T= 1) : 34.365 MB/sRandom Read 4KiB (Q= 8,T= 8) : 13.355 MB/s [ 3260.5 IOPS]Random Write 4KiB (Q= 8,T= 8) : 13.147 MB/s [ 3209.7 IOPS]Random Read 4KiB (Q= 32,T= 1) : 13.285 MB/s [ 3243.4 IOPS]Random Write 4KiB (Q= 32,T= 1) : 13.377 MB/s [ 3265.9 IOPS]Random Read 4KiB (Q= 1,T= 1) : 12.632 MB/s [ 3084.0 IOPS]Random Write 4KiB (Q= 1,T= 1) : 12.593 MB/s [ 3074.5 IOPS]Test : 1024 MiB [E: 0.0% (0.0/59.8 GiB)] (x5) [Interval=5 sec]Date : 2018/07/03 4:03:29OS : Windows 10 Professional [10.0 Build 17134] (x64)

128Gb version, read speed checkout at 400mb/s, but write speed only at around 60mb/s, was expecting >100mb/s. My mobo, Asus ROG CROSSHAIR X670E HERO, has USB 3.2 Gen2 USB Type-A ports. Tested on 3 ports, 2 direct and one via a Uni 4 port extender. I ordered 4 of these are they remain consistent.Nice body design and ok for the price I guess. Got it during the discount of around $12.99. Will use for OS boot, memtest and other recovery purposes.For large transfers I would look at external nvme with usb-C or Kingston 1tb for 1gbp/s read and write speed. Recommended otherwise.
