Died about a year 11/20/2019 4:33:36 AM

Pros: Lots of space decent speeds died while under warranty

Cons: Died in almost exactly 1 year from purchasing

Overall Review: Going to try for an RMA through Toshiba I lost over 2 tb of movies and TV shows but hopefully can at least get my money back depending on how the process goes will decide if I buy another Toshiba drive in the future. Just want to say that my Seagate 500gb has lasted over 8 years which is incredible and way beyond average life expectancy for a hdd especially since it was used daily for 4-5 years and it's still being used on occasion I don't expect that from every portable drive but come on Toshiba this should have lasted at least 3 years of moderate use.

2 Drives - Neither Works 6/22/2019 1:13:28 PM

Pros: Nice size

Cons: -Bought to replace 500GB USB 2.0 Samsung drives, cannot get these Toshiba drives to function properly
-Starts at 100 MB/s+ then drops to less than 1 MB/s after a few gigabytes transferred
-Large files behave better but can still "flood" the drive
-Tried 4 USB 3.0 cables, including y-cable for more power. Y-cable seemed to improve first time, but did not solve the issue and as of writing this review I'm getting 960 kB/s writing on a benchmark test with Y-cable
-Tried front and rear USB 3.0 parts, same issue
-Tried 2 USB 3.0 PCI cards, same issue (supplemental power was connected on both boards)
-Tried in ext4, NTFS, and FAT32, same issue
-Write cache on/off, power management on/off, same issue
-"iostat" command shows 100% utilization on drive, w_await less 1000 when working, but w_await "floods" to 10,000 and up to over 160,000 when drive stops working. Even if commands are cancelled drive will continue flashing as if it is writing for tens of minutes or more
-Format with erasure shows 7-10 MB/s in some areas for GB at a time, but most of drive actually erases close to 60 MB/s, cannot figure out why
-USB 2.0 plugs show same decaying transfer rates and "flooding" behavior
-Old USB 2.0 Samsung drives still work perfectly
-Data transfer rates extremely variable even as they decay
-Both units show similar behavior
-Cannot return units because data is now on drives and erasing the drive takes too long (see issue)
-Blue LED is an eyesore

Overall Review: If they worked, I'd be giving 4 or 5 eggs, but they don't. Huge waste of time.
Will update if I find problem in on my side.
