Its important to note that this drive is 6Gb/sec not 6GB/sec. GB is Gigabytes, Gb is gigabits, I know it sounds nitpicky, but thats a huge difference

You are correct (and previous answer is not). The drive interface is 6Gb/sec (that's gigabits per second), as it says on the label. This is the standard speed of Sata3. This translates to roughly 600MB/sec - plenty enough to carry the quoted 550 MB/ sec the drive is capable of.

There is no SATA 6.0. SATA 3 is 6.0 Gbps (Gigabits per second) so this is probably where your confusion comes from.So it's the best SATA there is.

Its a Solid State Drive...so it is much better than a regular hard drive or a 16gb USB drive. It doesn't spin, no moving parts, less mechanical error, and files store on it (like the operating system) will read much faster than a regular hard drive. I have a 120 gb solid state drive and my computer boots in 3 seconds. With that being said.....I also have a 2 tb drive as well but I play game and do video editing which this computer is not designed for.

It appears that the other hard drive has comparable specs. However it comes with a different firmware. Otherwise I think it is likely a matter of packaging and marketing.

This drive is NOT fast. If you want fast, buy the 8Gb micro Cruzer. I have both, and bought the 16gb because I love the no-cap-to-lose, and I love the 8Gb speed. But the 16bg is so much slower that Vista reports that Readyboost cannot use it. (The 8 gb said "Vista Readyboost" on the package, and I assumed that naturally the 16 gb would be fine. It's not, and doesn't say it is on the package.) After Vista tested it, it stated that it was too slow to be used by Readyboost, the somehow marked the unit and the option to use Readyboost no longer appears when I plug it in.

Hi J. Chen. The 300/500 MB/s refers to the write speed for the different capacities. The write speed is different for the 128GB, 256GB, and 500GB drives. The 512GB drive has the 500MB/s write speed.

They don't publish what speed it is. They source different hard drive manufacturers. More than likely it is 7200 to meet the specs. From the various reviews from professionals, it meets their published specs. The transfer rates are very good. I liked mine.

I tried a hybrid drive and it gave me similar performance to a SSD, 10 to 25% in initial load, no diference in between game load time and not much difference in start time. Basically not really worth it. The difference is like 36 sec vs 40 or 55 vs 102 sec.

It is rather confusing. On the link I provided, scroll down to the "Technical Details" part of the page. It reads "Minimum 20MB/ sec sequential read/write speeds." Best of luck!

Everything in digital world should be a power of "2" in their root ( "0" and "1"s, only two numbers). 1000 is not! So when you go from Byte to KiloByte, you have to divide the number with "1024" not "1000". Same thing happens when you go from Kilobyte to Megabyte to Gigabyte to Terabyte. When you buy a 2TB HDD you actually buy a 2000000000000byte drive and if you divide it with 1024 four times you get ~1.81TB. That's the real capacity it has! About the PS4; the drive is ~1862Gigabytes according to this calculation so if it shows 1760GB then you're missing ~102GBs of space. If PS4 reserves that amount for the system then there's nothing wrong with the drive...

Sata 6gb, the difference is speed...to benefit from the 6gbs, you have to have a compatible motherboard or else it will work on 3gbs (which would be fast anyways)

I wrote a non-techie review of my 64g and 128g. I compared writing 37.3 gig of data - the San Disk disk took 5:55 minutes for the 64g and 5:50 for the 128g. The other 2 (not cheapies) took between 25 and 36 minites. All were done with the same source data on the same computer using the same USB3 port. They were all USB 3 drives. Not sure what the specs are, SanDisk has them on their website, but I can tell you it is faster than any of the others out there except maybe the Lexar and the price on those is much higher.

I don't know the exact speeds, but it's one of the slower drives I have. I have the 8GB version and I don't recommend it.

It's SATA, and I believe SATA III (6GB/sec). At very least SATA II (3GB/sec).One thing to note is that if you intend to replace the mechanical drive with a solid state (which you should - makes these things ten times faster), you'll need a 7mm height SSD. 9.5mm won't fit.Ben

The drive is 5400rpm. Honestly I don't notice as my OS is installed on the SSD so the OS is very fast. All of my programs are on the 5400rpm drive.

It is not specified in any information included with the drive , nor anything I see on-line at WDC.com. Probably a 5,400 RPM drive but it doesn't really matter. The drive is intended for backing up data not for high performance data access. The slowest link will determine the transfer speed so the USB controller on your computer will be a limiter. It took me over 5 1/2 hours to copy 622 GB to this unit. It held close to a 30 MB/sec rate on a USB 2 port. About the same results for a Firewire 800 connection I have used on other tests on other (faster drives). My suggestion is ... don't worry about the RPMs. If you need backup space this will work well.

From my understanding of sata cables they are all the same. It is the transmission protocol that is different. That being said, this thing is totally passive. It just is a smaller configuration of the same connection. I would be looking at whether your ssd actually reaches 6gbps speeds. Most don't come close- that's a potential 750 Mb/sec. The bottle necks on these things have a lot more to do with the ssd's controller than the actual cable itself.
