Connected via the USB interface, the drive appears to Windows as an external drive, much as any other external USB drive. Bundled software for the "Expansion" series is limited to product registration software, and is pre-loaded on the drive, which comes factory formatted as a single NTFS partition with a Windows reported capacity of 1.89TB. According to Seagate's warranty checker, the internal drive was sold as a system component, and warranty service is obtainable from the system OEM. The complete drive carries a nominal 1 year warranty. My drive (purchased in August, 2013) is stated to be under warranty until October 2014.
The outer casing is two-piece, ABS plastic, held together entirely by snaps. It's fairly easy to open the casing using a flat-blade screwdriver, utility knife or spudger. Once the plastic casing is removed, the drive is attached to an aluminum carrier and attached USB-SATA interface circuit board by four screws on the side. The casing design is such that it can be opened non-destructively, and re-assembled, though in the process it will likely suffer cosmetic damage that will belie the fact that it was opened.
The internal drive is a Barracuda model ST2000DM001, which is a 6GBps SATA drive with 64MB cache and 7200 RPM spin speed. The drive can be re-purposed as an internal drive without having to wipe it first, and the casing functions nominally with a different hard drive installed in it. Installed in a Core i5-2300 desktop with 8GB of RAM, it managed a Windows Experience score of 5.9 (as the sole drive installed in that PC at the time).
BUT the new 3TB drives serial nums W1Fxxxxx using SC4x firmware model number has been changed from 9YN166 to 1E6166 as well and do not have NCQ. NCQ helps speed up buffer flushing so the drive do not have to finish commands and keep moving the heads back to write the MFT before and after each file copy. You can sort of fix this by Disabling write buffer flushing in windows.
The new drives still read fast at upto 200MB speeds. File copies starts at over 150MB/sec. But writes to the drive soon drops down to 40MB/sec or less.. I was really shocked since thats almost the speed of USB2. And file copies between my old 2TB drives never dropped under 100MB and even the older 1.5TB drives move files at 80-90MB/sec.. The transfer starts at 150MB/sec but steadily drops until it hits like 40MB/sec. This could be using the new seagate write technology to pack in more bits/inch where adjacent tracks have to also be rewritten so they have to read those into the buffer first. But I did not know those drives were out yet. I could find no info on the new firmware they are not on any websites.
My main drive is an SSD so I can copy files at max speeds to it. But copying from it gets slowed down after like 10GB or so. I even hooked up my 2TB drive via USB3 and my 1.5TB drive and file copying between them moves along at over 80MB, The old 160GB SATA1 copies at 45MB which is faster than the 3TB drive, which is correct since the 1.5TB drive is a 5 year old model and the 160GB is a decade old model. But even across a USB3 bus I am still getting over 80MB on these old drives and I only get under 40MB on the brand new drive. I do not know exactly what the problem is since I can copy 5GB of files at 150MB/sec.. it is only when I go to move large amounts that it slows down. The 2TB never slowed down like this, it does get slower as the inside tracks gets used but the 3TB is not even half full. Another thing I noticed is that with HDtune, the graph is not smooth, it varies between 150MB-200MB from start to finish, ending at 150MB-100MB at the end. While on all the other drives the graph sticks pretty close to +/-5Mb instead of the 50MB changes here. So not only does it not have NCQ it is also slowed down drastically.. When you are trying to backup 1TB of data, doing it at over 100MB is vastly different than doing it at 40MB. Maybe its the new technology since I seen reviews of the older 3TB drives and they were not doing this. Just make sure you do not get the W1Fxxxxx drives.. Not having NCQ is a major disappointment since it slows down drastically when moving a large number of small files and almost become unusable with windows write flushing enabled.
The W1Fxxxx letters mean...
S - SU - Suzhou China
W - WU - Wuxi China
Z - TK - Korat Thailand Teparuk plant in Thailand
F = 3 platters with either 5 or 6 heads, while E = 2 platters.
D, E, and F appear to designate 2, 4, and 6 heads.
Z1 drives have data densities of 1TB per platter, while the Z2 drives have 500GB platters. The Z is where it is manufactured.
WARNING please note! This 3TB drive gets HOT... The drives are rated upto 60C but they fail quicker the hotter it gets. My 2TB rarely gets to 50C and usually run at 40C. But placing it on a flat desk and moving files it got to 59C before I powered it off since at over 60C it triggers a smart attribute change. That is with a ceiling fan running over the case. I am not exactly sure where the trigger gets pulled for warranty purposes but my 1.5TB drive has hit over 70C often and that failed after less than 3000 or so hours. These are the only 2 drives I seen that get over 50C in decades, the old 500-MB (0.5GB) maxtor drives would get this hot. This is a very bad case! The holes at the bottom are useless to get rid of the heat and I had to place it on the side to make it run cooler around 50C Since the regular external is placed on its end and not flat like the expansion it does not matter which direction the drive is at. Which is still 10C hotter than running the bare drive inside the computer case. The plastic black case does not feel hot so you have to use a program that pulls the smart values to show you airflow temperatures.
These drives can cause SIGNIFICANT DATA LOSS in power loss situations. Because of the way the tracks are written, it is not just the data that is being written that is lost during a power failure but also data in adjacent tracks and entire files. If a small text file that is getting updated during a power failure, data in other files will also get corrupted/lost.
After using these drives for a month I give it a 1 STAR and not recommended for any use including backups. Pay the 5 bucks extra and get the regular drive without staggered tracks.
