SanDisk Ultra Flair 128 GB USB 3.0 Pen Drive (Black, Metal)

Max read & write I got is 37.07 & 20.58 MB's respectively, it averages around 30-35 for read and 20 for write; this is USB 2.0.USB 3.0 speeds are 150.6MBs read & 57.06MBs write, 4K random read/write is 9MB/1.5MB respectively - this is connected to a USB 3.0 slot in a PCI expansion card, exFat. Tested with NTFS sans compression, connected to a USB 3.0 slot with an extender cable. I'm mainly using this with a router for a makeshift NAS, router doesn't support exFAT, so its connected to a USB 3 port in NTFS, works great. You can either format it with Large FAT32 using Rufus or cmd line or NTFS/exFat using normal PC formatter. exFat is suggested but the next best choice is NTFS. Looks great as its a blend of glass & metal, seems sturdy at the same time. Heats up during large transfers but nothing out of the ordinary, it also cools down relatively swiftly when it does heat up; so glad I went with this over Ultra Fit. Highly recommended! SanDisk always makes reliable flash drives. ----------------------------------------------------------------------- CrystalDiskMark 6.0.0 x64 (C) 2007-2017 hiyohiyo Crystal Dew World : https://crystalmark.info/ ----------------------------------------------------------------------- * MB/s = 1,000,000 bytes/s [SATA/600 = 600,000,000 bytes/s] * KB = 1000 bytes, KiB = 1024 bytes Sequential Read (Q= 32,T= 1) : 150.597 MB/s Sequential Write (Q= 32,T= 1) : 57.062 MB/s Random Read 4KiB (Q= 8,T= 8) : 9.093 MB/s [ 2220.0 IOPS] Random Write 4KiB (Q= 8,T= 8) : 1.512 MB/s [ 369.1 IOPS] Random Read 4KiB (Q= 32,T= 1) : 9.076 MB/s [ 2215.8 IOPS] Random Write 4KiB (Q= 32,T= 1) : 1.430 MB/s [ 349.1 IOPS] Random Read 4KiB (Q= 1,T= 1) : 9.119 MB/s [ 2226.3 IOPS] Random Write 4KiB (Q= 1,T= 1) : 1.331 MB/s [ 325.0 IOPS] Test : 50 MiB [F: 0.0% (0.0/114.6 GiB)] (x5) [Interval=5 sec] Date : 2018/04/29 9:37:37 OS : Windows 10 Professional [10.0 Build 16299] (x64)

very nice 👍

Self space max. Bad

Ordered it about 2 weeks ago.. have been using it quite intensively and has performed great.. I hesitated while buying it because some users have complained of a heating problem, but on using it, I realised that it's because it's a metal body pendrive, so it heats up more than its plastic counterparts, but it doesn't affect performance... Looks sleek and classy... Only one slight drawback is that the rear part through which one can tie a thread is made of plastic, so may not be durable if you hang it on a keychain or something... No problems with the product.. has a 5 year Sandisk warranty..

128 GB memory card is very useful for large storage during travel and home. Using the device is so easy and value for money. Great style and light weight also.

I like the pen drive's memory (a mammoth 128 GB), sleek aesthetic looks, password protection and high speed of data transfer

Slightly gets heat.....But worth every penny....Love it...

I'm experiencing an issue with formatting or copying files from a USB drive. Whenever I attempt to perform these actions, I receive an error message stating that the disk is write protected. I have already tried removing the read-only access, but it didn't resolve the problem. Additionally, when I connect the USB drive to a TV, it is not detected. However, I can view the contents of the drive when it is connected to a laptop. Considering these circumstances, I believe it would be necessary to replace the corrupted drive.
