FIT USB flash drives

FIt formfactor is a very "low profile" USB flash drive that is actually perfect for use with both servers and desktop as a permanently attached backup storage. Drive almost does not protude from the USB port to chances to damage it are very low.  They still exist for laptop. So for laptop they are not zero, but for servers you can assume almost zero changes of accidental damage.

Ther are half-dozen models on the marter and the main difference is heat issues and write speed.  Lexar JumpDrive S45 128GB USB 3.0 Flash Drive - LJDS45-128ABNL (Black)  woths pretty cool and have decent write speed. There are a lot of complains about overheating of SanDisk FIT drives, but they are not really hot (approx 120F under heavy use). also write speed is slower, but for backup this is not critical. But they are the smallest. Samsung drive are in between

SanDisk provides 5 years warranty for its drives. 

Sandisk has a small orange indicator light

Lexar has a bright blue light.

When it is writing or reading, the light will blink attractively. Here is SanDisk response to the complains:

My name is Allen from SanDisk support. We appreciate your interest in SanDisk products and your review. SanDisk drives comply with industry specific standards and are tested to remain in acceptable temperature ranges under normal operating conditions in host and USB flash drive devices.

SanDisk drives are tested to comply to the safety standards in "Safety of Information Technology Equipment, IEC 60950-1", where the ambient temperature range is between 0°C and 35°C. SanDisk Ultra Fit can run a little warmer than other similar drives due to its high performance and compact form factor, which can limit the immediate dissipation of heat from the circuitry.

As you may be aware, the latest laptops and desktops also generate considerable amount of heat which can contribute to SanDisk Ultra Fit running warm while inserted in these hosts. Nevertheless the drive is tested to remain in acceptable temperature ranges under normal operating conditions so to not affect your host device. Please wait for 15-20 seconds after operation to remove/eject the drive before interacting with it.

However in case the drive is heating up exceptionally, please contact us at 1-866-SanDisk (726-3475) or submit a support request at www.sandisk.com/ask. We will assist you towards the best possible resolution.

Thank you,
SanDisk Support.

Like the size but it is not as fast as other USB 3.0 drives

The size is perfect for leaving in my laptop, no need to worry about bumping and breaking a full sized USB drive left in the port. The speed is better than any USB 2.0 drives I have but it is also not near the speed of the 3.0 drives I have tested.

Overall an OK selection if physical size is your reason for purchasing. Other drives have better speed and even format with a few MB more space.

I really don't like that the LED light is so bright and located ...

Size: 128GB

Verified Purchase

This drive is FAST and a big part of my traveling workstation. There are 2 design flaws, IMO. I really don't like that the LED light is so bright and located on 3 sides. It could stand to be smaller or not as bright because when working on your laptops late at night it can be distracting. I've covered mine with a little hockey tape. LOL The second design flaw is that you can easily loose them because there is no place to attach a little tag or strap to it. Granted, the size is why I bought them...but it would be nice to have a small wrist strap at the end to pull them out of the computer and keep track of easier.

I own 2 of these. I also own a SanDisk Ultra Fit 128GB drive as well. This drive is about 73% FASTER at writing...that's a huge HUGE difference in real world use. I gave the SanDisk to my dad to use in his car because he only needs to "Read' from the drive, while I need both Read/Write.

Moderate heat issue, but works fine otherwise

I bought both this product and the Sandisk UltraFit 128GB from Amazon. This product runs a lot cooler than the Sandisk, so file transfers don't slow down as often. Both products, when they heat up due to use, start throttling file transfers, especially on file writes. The Sandisk heats up after about 2 minutes of continuous use, dropping its sustained write speed to around 500KB per second. The Samsung heats up after about 4 minutes of continuous writes, and drops to about the same write speed.

Definitely worth the couple extra dollars vs the Sandisk

After owning a similar Sandisk drive, this device is a dream. The Samsung drive does NOT have the overheating issues the Sandisk USB 3 drives are known for. Because of this you can actually take advantage of the high speeds offed by USB 3. On the hotter Sandisk drives, even ones offering higher ostensible speeds, the overheating causes the drives to throttle the speed down, so I would rarely get better speeds than a USB 2 drive. With this drive I always get wonderful read speeds (about 130 MB/s) and very reasonable write speeds (30 - 60 MB/s). The build quality of this device is great and very much in line with what one would expect from Samsung. I only wish it came in black.

Logitech Users Beware

Size: 128 GB
|
Verified Purchase
Works as advertised, but there's one issue that significantly affects my use of this drive. It interferes badly with the Logitech wireless mouse I use on all my computers. This is well documented and out there on the web for anyone who Googles it, so shame on me for not researching it first. Not really a big deal in this case as it was a very cheap drive. I'll find some use for it. You just need to be aware of the interference with Logitech products if you use them and are considering this drive.

P.S. - This interference shouldn't be an issue if you have USB ports that are separated a bit, like one on each side of a laptop. I have all Apple machines, so the USB ports are all in one area. A Dell laptop or desktop should not have this problem as long as the drive and the wireless mouse dongle are separated.

[Nov 05, 2016] Affordable compact (FIT or bar form factor) 128 GB Flash drives

"FIT" form factor is the best as almost does not protrude from the USB port. There is a small (orange in case of SanDisk) indicator light and I kind of like it. When it is writing or reading, the light will blink. They are supposed to be plugged in and seldom pulled out, or pulled out fairly rarely. Perfect for local backup of OS.
Bar form factor protrude one inch or so. Which in many case is acceptable but still carry some risks.
