Compared to my other 8gb usb drive, it writes/reads large files at a much faster speed of ~25MB/s. My 8gb usb drive writes large files at ~4mb/s
However, it's very slow at write/reading numerous small files, much slower than my smaller usb drive.
It also lags when I try to browse directories and files in it.
But given its very large storage space of 128GB, I guess I'm supposed to use it to store very large files in the first place.
I'm happy with this purchase, but I'll be using it in conjunction with my 8gb usb drive to avoid the slow random access speed.

Update:
I was probably wrong to assume the read/write speed depends on the drive only. My 8gb usb drive is formatted with FAT32 (which may have accounted for the slow speed) and my Lexar with NTFS.
Later, I formatted the Lexar to exFAT and the lag was gone - small files write faster. However, read/write speed for large files has dropped to 15mb/s, which was a fair trade-off.

In short, choose between FAT32, exFAT and NTFS for your needs.
FAT32 seems very responsive for small files but place a 4GB limit on the individual file size and only does 4~5MB/s at most. Lexar came formatted with this if I remembered correctly.
exFAT is a tradeoff between responsiveness for small files and write speed for large files (15mb/s).
NTFS is very slow for numerous small files but the fastest for very large files (25mb/s).

Although the product literature claims the 128 GB version works with Mac OSX, this is not correct as regards the capacity meter nor is it true with regards to speed. This meter does not work properly on the Mac for any of the formatting options that I tried (NTFS, MS-DOS(Fat) and exFAt). It also does not work with any of the standard Mac formats. The Lexar web site has numerous FAQs, but none mentions this issue. Thus, if you have a Mac, and the capacity meter is important, you should not buy this drive.

The speed of this drive is also affected by the formatting. When any of the standard windows formats are used with Macs, the speed drops to half for both read and write relative to the speeds advertised. This may be due to the Mac having to convert data for the format. But since Macs read the windows formats, but none of my PCs read Mac formats, the windows formats are preferred.

The above negative comments do not apply for Windows users. When tested on my PC, the speeds were very close to those advertised. This drive needs a firmware update for use on Macs, and I returned the drive. My hope is they will update this drive in the near future so it actually works with Macs.

Update: 20 May 2012

After reading this review, a representative of Lexar contacted me and confirmed that one cannot use this flash drive on a Mac using Mac formatting if one wishes to use the capacity meter. Indeed, the capacity meter will only work if the original formatting is left unchanged from the MS-DOS(Fat) format. Any attempt to change this format will likely confuse the firmware and disable the capacity meter, even if one reformats the drive back to MS-DOS(fat).

After about a week of owning this product, now have gotten a fatal error. I have sent a mail to Lexar support. Let's see how fast they are to resolve the problem. I've had a MicroSD card fail on me, but not as quickly as this USB flash drive has failed.

Update: I'm upgrade this product from 1-star to 3-stars. They were prompt in a reply. They had me reformat the drive and then gave me updated software to place on the driver. One of the things which attracted me to the device is that it came with backup software. However, after running the backup software, I am not terribly fond of it as the backed up files are in an internal format. I'd prefer something which allows me to browse the contents of the drive to see what has been backed up without having to use specialized software to figure out what has been backed up.

Update 2: Since it has been working flawlessly since June 2012, I'll now update this again to 4-stars...

I never take the time to review products, but I had to take the time to review this one, and I am giving it five stars. I had a laptop which was had some serious issues, and I am not the type who likes to spend a lot of time backing up my files, so I would have lost over 3000 music files, 1000 pictures, and about 1000 word documents if it had not been for purchasing this device. I never back anything up because my experience with backing up computers is that its a slow process, that was just not the case with the lexar echo. I have all of my files, pictures, and music, downloaded and saved to the echo in about 1 hr, and I still have a good amount of space left on the echo. Its extremely portable and works with both pc and mac, and extremely user friendly. There is even an option to encrypt your information for added security. Well worth the price.

All I wanted was a 'reliable' flash drive with more than 32GB to backup my computer, and this drive excelled in every department:

********THE PROS**********
- Fast! (to me at least)
- Already loaded with a backup program (which I used instead of the Win7 backup)
- No cap to lose (the mid-section slides up to protect USB)
- Sleek/Very comfortable shape and size
- On-devise Indicator that tells you how much memory you have left/used up!
- Works for both MACs and PCs
- LED inticator to tell you when data is being read/transfered

*********THE CONS*********
- None yet...

I am already thinking I need the 128GB version in my life! If you have questions, let me know...
