SanDisk 32GB Ultra Luxe USB 3.1 Gen 1 Flash Drive - SDCZ74-032G-G46, Black

Rev 2/9/22 The 64GB version of this drive, and of the Sandisk Ultra-FIT, are excellent for creating and running encrypted Linux installations, which I use on "secure" mini-PCs. [1] The suitability of a particular type of drive for this purpose is due to the specifics of its implementation, and the only way to determine whether it's suitable is to try it. Smaller versions might also work well, but larger drives tend to have faster write-speeds. I decided to try an Ultra Luxe to avoid the plastic connector-shroud on the Ultra-FIT, which I've worn out with frequent plugging/unplugging, so that the bottom of the shroud came off, but the drive still worked fine, although caps don't stay put without tape. But there are various ways to avoid excessive plugging and unplugging, such as leaving the drive plugged into a "port protector" (an extender-adapter), although this defeats the purpose of the stubby case, which is to allow the drive to be plugged into a port without sticking out and creating a risk of damaging the drive or port as a result of hitting the drive. If you're using the drive to transfer data between PCs, you can use a KM switch such as a CKLau-64H2ua with a switched USB port to switch the drive between PCs. ` The fit is snug, but I wouldn't call it tight (perhaps there's some variation between units), and the drive I received didn't run particularly warm. How hot a drive runs seems to depend on the particular unit, the PC being used, and other factors. If a particular unit runs very hot, it might be due to an internal component failure. I have a 32GB Ultra-FIT which runs hot, which I used for an installation, and the installation developed problems soon after I started using it, indicating drive failure. SSDs provide a means of monitoring their temperature, and high temperature is considered to be an indication of imminent failure. Sandisk drives have a five-year warranty, but since failure is rare, I'd rather toss a $10 flash drive than to get it replaced. Another concern with a drive that runs hot is excessive power consumption, which is mainly a problem when using such a drive with battery-powered devices. But I suppose that the chips are tested for such things as excessive power consumption at the wafer level, and would never be used for a drive if they exceed the limit. But this can't predict whether a chip will fail after a short while, which is typically when they fail - if they last a short while, they'll last a long time, assuming that they aren't subjected to excessive voltages. When using a drive for storage on a Linux PC, it should be formatted in a Linux format (EXT4) for best write-speed. Encryption reduces write-speed, although this depends on how much processing-power the PC has. Notes [1] "Secure" by my definition - not NSA-spec, but NSA-proof, i.e. no internet connection, internal storage, or wireless circuitry, including in keyboards, monitors, printers, or KM switches, which switch keyboards and monitors between PCs. I use a Gigabyte mini-PC which I got from Amazon for about $180 including 8GB of DRAM as my "secure" PC, and it has all the power I need. It's nice not having to worry about security vs. the Thought Police (a dirty unconstitutional NSA black-op exposed by Snowden, who has apparently been exiled for life).

There's not much to say; it's a fast USB stick with good storage capacity. It also has a sturdy design so it can live happily on my keychain without the key attachment point breaking.

Does not disappoint in speed and reliability, and it's built quite nice. It get's get hot while in use, so don't hold on to it too long when removing it from your USB port. It cooldown in seconds, but I recommend using a keyring for better grip and comfort.

Good quality, Speedy Writes and Reads, it does get overly warm, some would say hot! Common problem with thumb drives.

Compact device that works really fast. Used it to install windows on a bew pc. It does get pretty hot when working for a bit, just be aware of that.

Excellent

Good product and works as a usb. Seems durable. Only complaint is that the hole for a ring is a little small. Mine tends to bind on my key chain.

It Get Pretty War When Loading Music

A good quality flash drive which prevents mp3 file damage. Used in car mp3 player as well as window 11 laptop.

It's a good drive, compact and all, but there is no shroud around the actual drive (its flush with the port) so sometimes it can be hard to pull out. Additionally, since the drive is fully metal outside, when doing data transfers it gets toasty on the outside. Pretty sure this is intentional to keep the actual controller and chips from overheating, but it can be enough to make you flinch if its constantly in use for a few minutes. But performance and price wise its really great.

国産のK社製は速度・熱の両方で足元にも及びません。価値があります。

使っているとき、本体が熱くなりますので少し心配になりますが、それ以外は良好です。

Habe mir von der Serie die 32,64 und 128GB Variante mehrfach (so 10Stück oder so)gekauft. Alle haben nachweislich die angegebe Kapazität (H2TestW als Testprogramm) und jedem sollte klar sein das technisch bei einem 128GB Stick im System nur 114GB angezeigt werden (Unterschied GB und GiB mal googln sollte helfen oder die Produktverpackung lesen) Das die USB-Sticks warm werden ist richtig, aber nicht so extrem wie es die meisten beschreiben, man kann ihn noch anfassen, und das ist auch vollkommen normal für so kompakte USB-Sticks mit hoher Kapazität. Alles in allem kann ich die Sticks nur empfehlen. Nachteil der wenige Kunden betrifft: das Datenrettungstool was es dazu gibt, ist nicht für Linux verfügbar.
