SanDisk Ultra Luxe 256GB, USB 3.2 Gen 1, Flash Drive, Upto 400MB/s R, Pendrive, Metal, 5Y Warranty (SDCZ74-256G-I35)

Best pendrive at this price for fast speed and metal body for long-term durability. If you are searching for sturdy pendrive it is good option. Due to Metal body it gets hot while using, but it's not an issue, it's normal. It is better than my old 2.0 pendrive, it's super fast. As company claims it touch almost 400 mpbs but some times it also touch 420 mbps on 3.1 usb port. I tested the transfer speed of this pendrive. On 2.0 usb port the write speed is between 25 to 60 mpbs. (Using exfat format with 4096 kilobytes) On 3.0 or 3.1 usb port the write speed is between 250 to 390 mbps or sometimes 415 mbps (Using exfat format with 4096 kilobytes) And Read speed are same on 2.0, 3.0 and 3.1 usb ports upto 350 to 370 mbps. I brought 128gb variant and shows 115gb is usable on both PC and phone. ⚠️ Don't purchase extended warranty plan for this pendrive because onsitego doesn't accept extended warranty for those products which has more than 4 years manufacturer warranty. ⚠️ But one question, very first time I plug this pendrive to my pc it shows 119gb usable but after I format this pendrive with default format (Using exfat format with 4096 kilobytes) it's shows 115gb why? Overall I'm satisfied with this pendrive.

Model : SanDisk Ultra Luxe USB 3.2 Gen 1 Flash Drive. 64GB Speeds upto 150 MB/s READ (SDCZ74-064G-I35) Test System : USB 3.2 Gen 1 (rear port), SATA SSD. First of all the drive did get warm but it never got as hot as some reviewers claim. Even when copying 6.31GB (3095 folders). JFYI : The USB-IF (USB Implementers Forum) rebranded USB 3.0 as USB 3.2 Gen 1. BTW : there is a newer model SDCZ74-064G-G46 with 300 MB/s READ. The USB flash drive had a unusual MBR (USB-HDD+). Windows reported the capacity as 57.2GB. CRYSTALDISKMARK : synthetic benchmark which has no relation to real-life usage. FAT32 : Seq read speeds were roughly the same, more than 160 MB/s, for 256, 512 & 1024 MiB. FAT32 : Seq write speeds were more than 65 MB/s for 256 & 512 MiB and 38 MB/s for 1024 MiB. NTFS : Seq read speeds were roughly the same, more than 155 MB/s, for 256, 512 & 1024 MiB. NTFS : Seq write speeds were more than 65 MB/s for 256 & 512 MiB and 25 MB/s for 1024 MiB. Screenshots for all 6 CrystalDiskMark tests attached. REAL LIFE WRITE SPEEDS : I wanted to know what I could expect on my PC. FAT32 : 434 image files, average file size 5.1 MB took 144 secs (15.6 MB/s) NTFS : 434 image files, average file size 5.1 MB took 71 secs (31.6 MB/s) FAT32 : 95 image files, average file size 5.1 MB took 11 secs (41.0 MB/s) NTFS : 95 image files, average file size 5.1 MB took 9 secs (54.0 MB/s) FAT32 : 960 various files, average file size 4.5 MB took 241 secs (17.7 MB/s) MTFS : 960 various files, average file size 4.5 MB took 187 secs (22.8 MB/s) (these were Windows installer files, one file was 3716 MB) FAT32 : 1 file, size 65 MB took 1.4 secs (46 MB/s) NTFS : 1 file, size 65 MB took 1.1 secs (59 MB/s) FAT32 : 1 file, size 485 MB took 8.8 secs (55 MB/s) NTFS : 1 file, size 485 MB took 8.3 secs (57 MB/s) REAL LIFE READ SPEEDS : difficult to test, actually. FAT32 : 1 file, size 485 MB took 4.4 secs (112 MB/s) NTFS : 1 file, size 485 MB took 4.7 secs (102 MB/s) FAT32 : 95 image files, average file size 5.1 MB took 6.8 secs (72.0 MB/s) NTFS : 95 image files, average file size 5.1 MB took 7.5 secs (65.0 MB/s) So as long as you write files smaller than say 512 MB each AND the total size is less than about 1024 MB, you should get write speeds of more than 40 MB/s. For single (not large) files you should get more than 55 MB/s. NTFS is generally faster than FAT32 for writing. For reading you should easily get more than 100 MB/s. FAT32 is faster for reading. Keep in mind performance may differ on your system depending on your hardware. Screenshots of some tests attached.

Drive is very good, sturdy, fast reading, copy and writing. The one and only draw back is that the pen drive gets very hot like extreme hot, sometimes it feel like it will catch fire or the components inside pendrive starts melting. It's better to copy file to pendrive or copy from pendrive and eject the pendrive soon, I used this pending to watch a movie and connected it to TV, after 2hours i removed the pendrive it was not that hot like it hot when connected to pc/laptop. If u don't like your pendrive to get hot then don't buy this, If ur ok then go for it.
