WD Blue 1TB Laptop 7mm Hard Drive: 2.5 Inch, SATA 6Gb/s, 5400 RPM, 8MB Cache (WD10SPCX),Black, grey

Basically this is a normal and low speed disk, compare with recent SMR HDD, hybrid HDD and SSD. And the performance has no surprise, less than 110MB/s read and write speed. And in real copy file test it usually low down to 40-70MB/s. But this seems this is only choice if you need a 2.5" 7MM PMR disk. So the only reason to choose this HDD is PMR. SMR disk need rewrite the whole block if you need write something beside already exist data block. So after SMR disk become full of data, it will be very lag when access it. So it is not fitted running an system on it, especially windows. And SMR usually has more higher fault rate than PMR one, if you use it as a working disk to do frequencies small file read and write. So this disk is very suitable for laptop without SSD, and it used as needed a stable and reliable disk to work. And also this disk is more quite than my old Seagate SMR disk, which usually let the magnetic heads stay on the landing area and make noise when start to access the disk (It has a large internal cache and the magnetic heads usually don't need to access disk in real).

I bought the WD Blue 1 TB drive to make an external hard drive. In testing described below, it performs great. To summarize, I highly recommend the drive. For those that want more detail, the WD Blue (and Black) drives are recommended by WD for mobile use. The Blue would have a 2 year warranty. The Black are 5 years. Specifically, this Blue drive is inside a Transcend StoreJet 25S3 2.5" drive enclosure. The enclosure is USB 3.0 rated. I connected the drive to a USB port on the test rig. Then used HD Tune Pro 5.60 software to test. Test rig Operating System: Windows 7 Home Premium 64-bit SP1 CPU: Intel Core i5 4590 @ 3.30GHz RAM: 8.00GB Single-Channel DDR3 @ 799MHz (9-9-9-24) Motherboard: Gigabyte Technology Co., Ltd. Z97X-UD5H Graphics: 2047MB NVIDIA GeForce GTX 750 Ti (EVGA) SSD for OS, HDD for data Transfer rate test run File Size: 500 MB Data pattern: Random Sequential read 112315 KB/s Sequential write 76924 KB/s Random read 131 IOPS Random write 347 IOPS Random read (queue depth = 32) 130 IOPS Random write (queue depth = 32) 328 IOPS With same file size and data pattern set to zero, random read was 133 IOPS and random write was 327 IOPS. The Wikipedia IOPS entry states for a 7200 rpm drive, ~75-100 IOPS is average. For this 5400 rpm drive to have 130 IOPS as it's slowest run is amazing. That's a speedy drive for the price point for backing data up to. In closing, I highly recommend this drive.

Super fast delivery. Works great so far. I would give a five stars if the the hard drive is well-packaged, but it was delivered in a regular first-class mail envelope with little shock-proofing material. The envelope was dropped at the front door and I do not know what the impact will be.

De excelente calidad este disco

As others have said, this is currently the only 1T HDD that will fit in computers requiring a 7mm thick HDD. In my case it fit in a Dell XPS l1702. When I traded it out with my second HDD, I noticed I still had 1-2mm clearance between the thickness of the old drive and the new one, thus leading me to believe maybe a 9mm would have worked. Still happy with this one though. On a side note for those wanting to clone HDD's. Use one of the free programs (I used Macrium Reflect). I found a Youtube video and it made it look easy. The only hiccup I ran into was after I cloned it, I had to go into Disc Management and expand the new larger HDD to fill all unallocated space. I tried to change the Disc Letters from here but it will block you if you have any system files on that disc. In my setup, I was cloning my second HDD to a larger (internal) storage drive and the pagefile was located on it. I had to move it to C drive, switch letters of the new and old storage drives, then move the pagefile back to the new HDD. I installed it and it worked great with all programs linking to the new HDD seamlessly.

This hard drive is great and runs as expected. I bought it to replace the 500GB on my Lenovo Ideapad U430 Touch. It runs every bit as well as that drive with double the capacity. When I started my search for a new hard drive I didn't realize there were "slim" 2.5" drives. This one is by far the most reasonably priced with a brand that can generally be trusted. I'm happy with it!

This says its new and it is not. It was manufactued in 2014, had almost 5k hrs run time, 3k power cycles, and came in a plain white padded envelope. Also had corrosion on the metal case and in the pins.

Bought for my security cameras system. Easily installed with no issues and came packaged protectively. Will be buying again when needed. Highly recommend.

Although the advertised speed is the same, I've noticed a decrease in loading times for open world games such as The Witcher, Arkham Knight etc. Extremely easy to install asome long as you have a PC/Laptop and USB stick of at least 2gb (I got a 16gb SanDisk USB 3.0 to hand. Total time to install was 15 minutes. Save games game be downloaded from the PSN Cloud or a USB stick. Only draw back is reinstalling games but even that doesn't take that long if you have a decent broadband connection. Worth every penny.

It arrived in perfect shape, installed properly, and worked as promised.

lo que mas me gusta de los productos WD es que son confiables y duraderos. Este producto lo escogi para ampliar la memoria de mi laptop pues venia solo con 500GB. No hay mucho que decir a un año de su compra / instalacion funciona sin problemas.

Muy Buen producto que ha satisfecho mis aspectativas, tal cual como lo veia en la descripcion que vi para la compra

Nach einer Woche kann man noch kein Resüme über die Qualität der Platte ziehen, aber folgendes fällt auf: - Die Sektoren haben 4096 Byte (statt 512), d. h. dass die meisten (alle?) Imageprogramme (Acronis, CloneZilla, dd ...) NICHT von einer alten auf diese Platte klonen können. Wer also klonen will/muss - Finger weg. Oder es findet sich eine Software, die es kann ... - Booten kann von dieser Sektorgröße nur ein Rechner mit UEFI, ältere Rechner mit BIOS können das NICHT! - Laufgeräusche sind ähnlich meiner alten 320 GB Hitachi - Mechanische Geräusche (Kopfjustierung) sind subjektiv etwas lauter, aber nicht problematisch Sonst tut sie, was sie soll und verrichtet unauffällig ihren Dienst. Vor allem ist sie groß ;-)
