Drives failed - AVOID!

I bought 2 of these and they have failed after 2-3 months of light work. Lexar will only replace if you send them back in the post and mine had confidential info on so I am not happy to post them. Asked for assistance and they won't budge, waste of money and don't trust them with your data!

huge storage

fast and huge storage

  • from Orillia, ON


After the first use this drive failed. I am not able to format it on ANY computer - Mac or PC. Now we know why they were on sale for so cheap. VERY disappointed.

Best USB Drive I have Ever Seen

I have many USB Memory drives, but the real winner on this one is the way that you can password protect all of the files on your Lexar JumpDrive. I wish the software would run on my other USB Drives. If I cannot find comparable software for the older USB drives I will replace them with Lexar drives.

  • from Saint-sauveur, QC

Great price great service

Got it on sale, got it within 4 days and works great.

  • from CBS , Newfoundland

Awesome product.

LeXara has great products. This drives write speed is fast and the 128g is great for storing documents, music and videos.

  • from Cobble Hill, BC

Does the job, fast indeed!

As mentioned in previous review, I bought it as it was on sale, which was a good deal. Not sure I would have otherwise. Only complaint is no lanyard, so you can't attach it to your keys or anything else, that is quite annoying, easy to lose...

  • from Edmonton, AB

Open ended cap

It is a good bargain with free delivery. Don't like the open ended cap.

  • from Gatineau Quebec

Lexar jumpdrive USB Jumpdrive

Very pleased with my purchase product is easy to use and very fast. Delivery was very quick. I will not hesitate to buy from Best By again.

  • from Kingston, ON

Great for backup of very large files

Great flash drive for backing up high-definition videos without try to find space in the cloud. Yes, it is small--it will be very easy to lose, so I renamed it with my telephone number should that day ever come to pass. Works like any other flash drive so far. Definitely a good buy when on sale.

  • from Surrey, BC

Pleasantly Surprised with this USB Drive Speed

I expected the drive to be fast but it is much faster than I imagined. What really surprised my was the fact that this drive is even more than 40% faster than my WD (Western Digital) My Book Live network drive that is obviously connect with Ethernet connection. The WD My Book Live is only about 2 or 3 years old. Using this USB now for backing up my data now everyday.

  • from Candiac, QC

Already broken after only 1 week

Do NOT buy this product. I left the USB connected to my computer for 1 week to use as an extension and it decided not to work anymore. Tried reformatting it, but no luck. The USB drive is not recognized on my laptop or any other PC I try it own.

  • from Cambridge, ON

Works As Described

I bought two of these to plug into my router's USB ports for network storage on my network. The first thing I did was open DiskPart within Windows and clean the disks of any pre-loaded encryption software. Once done, i formatted both as exFat and made sure they mounted within Windows. No issues. Plugged both into my router and they were recognized. No issues copying data to and from them. I bought these over the other models that slide out (internally) and frequently break. These one have a better "end cap", it still slides, but seems it will hold up better. They work best with USB 3.0 ports. If you only have 2.0 or 1.1 ports on your computer, the speed will limited to the speed of those ports.

  • from Vancouver, BC

Not Speedy Gonzales

Transfer speed is not unlike USB 2.0, expected a lot faster since it is suppose to be USB 3.0

  • from Thunder Bay, ON

Only if on sale.

Very good deal on sale with free delivery. Works well as advertised. Not impressed with open ended cap and no lanyard. Delivery was poor but probably due to pending postal strike.

  • from Brossard, Quebec

The usb storage device you really can say is fast!!!!

Fast reliable and compact design ... Keeps all My files securely stored in convient place and above fast, very happy with my purchase.

  • from Victoria, BC

It's sooooooo good

Much wow. No error.

  • from Repentigny, QC

Not Working

I received it, package was correct. Tried to transfer a couple of gig to see if everything was working well. Unfortunately it stopped working after a few minutes. Send it back to Best Buy and ask for a replacement, I was simply reimburse. First and last time I buy something online from BestBuy, horrible experience

  • from Ottawa, ON

Very bad

I have already formated it twice in two weeks, lost my documents aswell.

  • from North Vancouver, BC

Great Product

Has worked well for me in the 3 weeks that I've owned the product, fast, stable and tons of space. Beats a portable hard drive any day.

  • from Toronto, ON


Happy to have purchased this jump drive, will use it for many things, lots of storage.

  • from Toronto, ON


Super fast and nice and small so it fits in tightly spaced usb ports.

  • from Calgary, AB

I bought this unit for around 30 dollars on sale

This little guy came up for sale for around [price] bucks and i bought one. Bestbuy shipped it reasonably quickly. I do not have USB 3.0 ports, so i can't speak to the 3.0 data transfer rates, but it works well with all of my 2.0 computers, and moves video flawlessly onto my samsung teevee via the usb port of unknown specification. This usb drive has more than 70 percent of the capacity of my previous laptop and cost less than a movie date... amazing.

  • from Grande Prairie

Huge Storage on a thumb drive

Very handy to have such a small flash drive with so much storage. I bought two while they were on sale. I have almost all my music on one so I can take anywhere.

  • from Guelph, ON

Large capacity, fast speed, best buy when it is on sale

Fast shipping, item arrived two days after putting an order on line. Connect to USB 3.0 port and test read and write against a ram disk drive under windows 10. 80MB/s write, too fast to record reading speed for a 1GB file. Overall, unbeatable for the quality and price

  • from Kitchener, ON

Great Value

Great value when on sale. Easy to use - Plug and play!

Unreliable Lexar JumpDrive S55 128GB

I purchased 2 of these thumdrives on sale online.... One worked and the other worked for 2 days and then was no longer accessible... I kept getting a msg saying the files system was corrupt or unreadable, I was not able to FORMAT it on 3 different computers. It was exchanged at the local BB store (no hassles) the new drive also worked for about 4 days and then then same error occured... lost all the files on the drive and again was not able to format or use the drive in anyway... tried on 3 different computers. The second drive that failed was not used on the same computer as the first drive that failed. The other thumdrive is still working, but I'm not sure for how long. I would NOT recommend these drives since they are unreliable

BAD Experience

  • from Sault Sainte Marie, ON

Lex Drive 128GB

  • from Toronto, ON


So far so good!

  • from Ajax, ON

Unreliable - cheap material

I see a lot of good feed back of this item but mine died on first use. Took it Bestbuy for return but they refused to take it back instead gave me exchange of same item. As I have no longer have confidence of this item, I am not happy with this item and Bestbuy return experience as I don't want same [] again. Unhappy customer.

  • from Fredericton, NB

Decent but problematic

It works as a standard flash drive, but unfortunately my Samsung smart TV can't read it, no matter if formatted as exFAT or NTFS, the TV reads smaller flash drives and larger external hard drives fine though.

  • from Newmarket, ON

Storage of all my photos and music

Have backed up all my photos and music with quality storage. Delivery exceptional.
