Lexar Echo MX 64 GB Backup Flash Drive LEHMX64GBSBNA

 (33 customer reviews)

I've had this USB drive for 2 weeks so far, and it has performed perfectly. I have about 34,000 files I store on it, which totals about 55 gb at this point in time. I expect to gradually increase the files to perhaps 80 gb over the next year or so, and I will use a second 128 gb drive as insurance in case either one should fail. I've used the 64 gb Lexars before this, and they worked well too. The speed of these drives is good reading (on Windows XP SP3), but writing averages about 4 megabytes per second long-term for ad-hoc writing. I've been criticized in the past for quoting low speeds like this, but I have 30 or more flash drives, a Dell desktop, Samsung laptop (both WinXP), a Macbook Air, and a Mac desktop, and that's really all the speed you get once you get your files backed up the first time and do incremental backups after that, writing only the files that recently changed.

Note: This USB drive does not come with a cap for the USB connector.

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.

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.
