Flash Drives 10 Pack 16GB USB Drive Bulk USB 3.0 Thumb Drives 16GB Memory Stick with LED Indicator Keychain Hole (Black 10-Pack)

I've been doing PC repair for over 20 years, and I've been through my fair share of everything from the "cheapies" to the name brand flash drives, and this 10 pack (I bought the 32GB's) is one of the best deals I've come across in quite a while.In backing-up clients' data, I do a lot of writing/rewriting data to USB drives. They do wear out... As of my writing this review, I've had these drives for just over 6 months, and I haven't had a single issue with any of the 10 drives. Couldn't be more pleased, unless they were free. LOL

These will work for what I need it for, moving my uncompressed music over from CD to Flash drive so I can have a 200 songs to play through on one flash drive. to move 14 songs, 671mb took about 90 seconds not that fast. But thats ok, cause all I am doing is moving songs onto these drives to play on my high end Oppo Blu ray Media player. 16gb is all I ant to load my Fav songs or artist onto a flash drive to play them uncompressed, MP3 on a high end Yamaha THX system just does not cut it. So these will work perfect. The cost is at the right price. Moving small files with these drives are ok and fast enough like music or pics. I would not want to be copying or moving 2GB's at a time with these drives, they just not fast enough, so they are great fro my type of use. I give it a 3 star for copying and moving files, but give it 5 stars for playback or reading on the drives for a final 4 star total.

I purchased these on sale for less than $20, which makes them an excellent value at that price. I benchmarked all five drives. The read speed varied from 60 MB/s to 100 MB/s on the five different drives. That is quite a spread since these are supposedly all the same drive. Even at 60 MB/s, they are worth the price. The write speed was a different matter and all the drives ran at about 25 MB/s, with only a variance of 1 - 2 MB. Not the fastest, but acceptable at this price point. It does make me wonder about the long term life of these units. Time will tell.

The drives themselves show no label or marking and look exactly like the USB 2's I returned because they didn't work at all. Supposedly USB 3 with 16G. In over an hour and half I could not load 3G worth of photos. When I finally could partially load one, then it wouldn't open. A tiny cheap 16G Cruiser Edge that I have had for a while loaded the same data, all 5G of it in 15 minutes. Only I.D. on the box was a stick on paper label that said that it was 16G USB 3. I seriously doubt all of that. Label did say made in China but that's no longer grounds for complaint since that's where most of them are made.

The first 4 drives out of the box that I tested were all dead (computer shows input/output errors when trying to use the drives):[678042.730672] usb 1-1: device descriptor read/64, error -71[678045.271545] sd 3:0:0:0: [sdb] tag#0 FAILED Result: hostbyte=DID_TIME_OUT driverbyte=DRIVER_OK cmd_age=34s[678045.271570] blk_update_request: I/O error, dev sdb, sector 12184 op 0x0:(READ) flags 0x84700 phys_seg 15 prio class 0Jan 22 13:40:22 localhost kernel: [679576.166765] INFO: task scsi_eh_3:72589 blocked for more than 483 seconds.Jan 22 13:40:22 localhost kernel: [679576.166774] Not tainted 5.14.0-1-amd64 #1 Debian 5.14.6-2Jan 22 13:40:22 localhost kernel: [679576.166777] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.Jan 22 13:40:22 localhost kernel: [679576.166778] task:scsi_eh_3 state:D stack: 0 pid:72589 ppid: 2 flags:0x00004000Jan 22 13:40:22 localhost kernel: [679576.166783] Call Trace:Jan 22 13:40:22 localhost kernel: [679576.166787] __schedule+0x2f0/0x910Jan 22 13:40:22 localhost kernel: [679576.166793] schedule+0x44/0xa0Jan 22 13:40:22 localhost kernel: [679576.166795] schedule_preempt_disabled+0xa/0x10Jan 22 13:40:22 localhost kernel: [679576.166798] __mutex_lock.constprop.0+0x28a/0x440Jan 22 13:40:22 localhost kernel: [679576.166803] device_reset+0x1d/0x50 [usb_storage]Jan 22 13:40:22 localhost kernel: [679576.166810] scsi_eh_ready_devs+0x6b8/0xd00 [scsi_mod]Jan 22 13:40:22 localhost kernel: [679576.166826] ? __pm_runtime_resume+0x58/0x80Jan 22 13:40:22 localhost kernel: [679576.166830] scsi_error_handler+0x433/0x510 [scsi_mod]Jan 22 13:40:22 localhost kernel: [679576.166841] ? scsi_eh_get_sense+0x250/0x250 [scsi_mod]Jan 22 13:40:22 localhost kernel: [679576.166852] kthread+0x127/0x150Jan 22 13:40:22 localhost kernel: [679576.166857] ? set_kthread_struct+0x40/0x40Jan 22 13:40:22 localhost kernel: [679576.166860] ret_from_fork+0x22/0x30

Every time I buy this item, 9 times out of 10 of them work, with 1 of them being a dead drive. I don't know why they can get away with this problem - somehow they get past their own quality control and get to sell thm here on Amazon.comI've started to complain that their 1 out of 10 drives are faulty to a Amazon chat employee and she says that they can only authorize $7.99 per order refund to me. I will definitely do this at once - please stop selling dud drives.

great usb 3 to work with. have been using it as a bootable drives for my work. have been using usb 2, these drives have cut my work time in half

A while ago, hard drive manufacturers started to define a gigabyte and 1000 megabytes instead of the more correct 1024 megabytes. Western Digital and Seagate, and others were both sued over the discrepancy.I'm sad to say that this flash memory drive has adopted the same approach. Advertised as 64GB, actual capacity is 58.5GB.The price is certainly right, and they're fast enough, just know what you're getting in to.
