Corsair Flash Survivor Stealth 64GB USB 3.0 Flash Drive, Black (CMFSS3B-64GB)

Once single file exceeds aroud 5GB, transfer speed would drop from 150-180m/s to 10-20m/s, which is kind of weird.

Loved the body and i am using it regularly still i will say SanDisk is much faster than this ❤️

Great product, holding up very well so far.

I use it to back up my pharmacy patient files every night. I use 7 of these. One for each night of the week. We write about 60G of data every day, not just an incremental backup and do a verification on the backup. It's been about a year and a half, data integrity is still good. No errors. Not the fastest usb key to write to, but slow and steady makes for reliability.

İnanılmaz iyi bir usb . Tonmeister , Dj , Müzisyen kısaca müzik ile uğraşan herkesin almasını tavsiye ederim işlem süreleri çok hızlı. Ve çok iyi korunaklı bir usb. Parasını sonuna kadar hak ediyor .

The casing is rock solid, and the capacity reports correctly, but this thing is a sluggard. Transfer speeds are nowhere near those demonstrated by other 3.0 devices.

Good: People have claimed that they've run over this thing with a truck without damaging it. I haven't put it to such an extreme test, but I believe them. Screw cap makes it robust and genuinely waterproof, plus reducing the chance of accidentally losing it. I've used faster USB3 drives, but this has reasonably fast read/write speeds. Good price for what you get.Bad: The cylindrical form factor makes it awkward on a keychain; this was not my intended use so not a problem for me. I was going to write that 16GB is rather low capacity at a rather high price by modern standards, but I just pulled up the product description and discovered that they're now offering up to 256GB in the same package (including a 64GB for 50 cents more than the 16GB version; grr.) The 256GB version is a few bucks more than the ruggedized drive I have on my keychain; the added water resistance (mine just has a conventional press-on rubber cap) is probably worth the price difference.Bottom line: This thing looks like it's just about indestructible, and the higher-capacity drives now exist and sell for a decent price. If you need a flash drive that can withstand a lot of abuse, this is it. Five stars.
