3 out of 5 eggsQuestionable

This review is from: Toshiba MG03ACA MG03ACA100 1 TB 3.5" Internal Hard Drive

Pros: Fast read speeds 122MB/s
Decent price

Cons: Slow write speed 13MB/s Unacceptable
Very loud - sounds like someone dragging their fingernails across a screen

Other Thoughts: Write speeds are unacceptably slow. An old Barracuda 7200.10 80Gb drive (7yrs old) outperformed this Toshiba 1Gb on three of my systems (HTPC, Dell T410 PowerEdge Server, and gaming rig A8N32SLI Deluxe/185opty.
I tested across multiple platforms and operating systems to be fair and deduce what the problem might be. Ensured during testing that PIO was not selected and DMA mode was used. No heat issues, swapped out cables, you get the picture. My guess is a bad write head. Used HD Tune Pro 5.5 and Sandra. Three stars because drive has not failed (yet) and not 5 stars because I still have UDMA drives from the 90s that kick this things rear. Boooooo!

5 out of 5 eggsAmazing value if you know what you're buying

This review is from: Toshiba MG03ACA MG03ACA100 1 TB 3.5" Internal Hard Drive

Pros: I ordered 5 for a RAID5 config with the 3ware 9750-8i.

They came more securely packaged than any drives I've ever bought (I've bought from most major companies).

All 5 worked and have been working for over a week in that RAID5 environment.

I get 600Mb/s read speeds and >500Mb/s write speeds in the RAID5 (note: this only works with a true hardware RAID), which tells you that the individual drive speed is about 1/4 of that, since RAID5 read is theoretically (n-1)(speed of the individual drive.)

Cons: They don't come with a manual, but if you know what you're buying, you probably don't need one.

Other Thoughts: Very cheap for what you are getting. You can't tell unless you are looking at the manufacturer's website, but this drive is not in the same class as drives like the Seagate Barracuda or WD Black. The key specification here is URE rate, which stands for Unrecoverable Read Error rate. The Barracuda and Black and most others in that price range have a URE rate of 1 URE for every 1e14 bits read, which means you can expect 1 URE for every 12ish TBs read from the disk.

For this drive, however, the URE rate is 1 URE for every 1e15 bits read, which means that, when filled with data, this drive can be read 100 times before it will have a URE. This is not true for all Toshiba drives, of course. But in order to get this performance from another company, you have to pay about 40% more.
