what is the difference between this hard drive 3.0GB and the 2.5 GB i have no idea the difference between both

Gb/s refers to the data transfer rate, 3.0 reads transfer half a gigabit more per second.

I think this indicates the type of SATA interface speed. There's SATA I (1.5GB/s), SATA II (3.0GB/s), and SATA III (6.0GB/s). The higher the SATA interface, the greater the potential bandwidth throughput it can support.

I am not qualified to answer your question. I was directed by my IT person to purchase the item to repair surveillance DVR. Sorry.

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.

The drive works well. USB 3.0 is faster only if the computer being used is too. The drive is slightly smaller than WD, Toshiba, etc. But it is not significantly smaller or faster than a like WD. I think WD comes in 2TB for about the same price.

It is a 2.5 inch internal hard drive. It is a laptop hard drive, all laptop's take a 2.5 inch harddrive, however not all are a SATA. Most are anymore, if you are going to put it in a desktop you want need an adapter tray. For the price this is a nice drive.

Because ~5% is partitioned off by the manufacturer for the purposes of read/write - as you do not defrag am SSD, this is required to allow the data to be cleaned up within the system This is still a 512 disc, which will actually mean ~500 for use, less ~5% for SSD specific cleanup tasking - unlike "normal" HDDs the 480 noted is the amount you will actually have to access

If you are trying to use this as an internal HDD, you might want to double check on the size there. That's a 3.5" HDD commonly used in desktops; unless you were planning on using this drive in an external HDD rig I would suggest you look into the 2.5" HDDs.*Suggestion: go with <Western Digital Bare Drives 2.5 Inch, Low Profile, 5400 RPM, SATA II, 8MB Cache 500GB Mobile Hard Drive, Blue WD5000LPVT> it's only $3 more ($43.99) than that desktop HDD for double the capacity.

Looks like the size question got answered already, after using it for a few months it seems the C drive is really just supposed to be 100% for your operating system. The system will boot/restart in a matter of seconds. the 1TB 5400RPM Hard Drive has plenty of capacity to store everything else.

I does come with a 2.5 inch hard drive. I personally backed the hard drive (80 GB) and installed a 500 GB instead. I copied the backup to th new hard drive. It came with Vista, but I installed windows 7 professional.

Thanks Pete. I was considering this as I figured this was digital but I am guessing its not? Wanted to avoid the mechanics of a 3.5. I have an ssd drive in a pc I built and it screams. So this hard drive spins then I take it and is not digital as I first assumed. I see now that assumption was wrong and there is no advantage other than size. Thanks!

the difference between usb 2.0 and usb 3.0 is the data transfer speed. 3.0 is can be 10x faster than 2.0, the other difference is 3.0 has 9 pins, 2.0 has 4pins a usb 3.0 drive can be plugged into a computer that has 2.0 but the drive will operate at 2.0 speed

Yes and no, I have two of them (2TB and 4TB), the 2TB is 7200 but the 4TB is 5900. It appears all of them are 7200 except for the 4TB. The models of the actual (internal) drives are ST2000DM001 and ST4000DM000. In case you want to google some more.

( BY THE WAY IM USING THIS COMPUTER RIGHT NOW LOL!!!)

Yes. The 3.5 handles all desktop hard drives. The 2.5 handles all lap top hard drives. The only thing to make sure of on this model is that your hard drive is a SATA or a ATA connection.

This external hard drive contains a SATA-2 5400 rpm hard drive with a 8mb buffer.I would tell you the model number but it gets deleted when I post it.I would tell you how I know for sure but that gets deleted also.So in other words you just need to use your noodle and seek out the info you need; there are ways but this will probably get deleted to so what's the point in all of this?PS I Bought this thing and I have hands on experience with it!

Sorry, I don't understand the question. I don't know much about the drive. The one in my Dell Inspiron failed and this was a good economical replacement.

Looking at the HD720 spec, I immediately notice this difference ~ "Built In 3.5" SATA/SATA2 Hard Disk Drive Bay With Up To 3TB of Storage Space (HDD is not included). It Can Also Be Used as USB 3.0 High Speed External Hard Drive Enclosure" HD700 does not have HDD enclosure.
