User questions & answers

Question:	Is the 2tb (st2000dm008) internal hard drive cmr or smr
Answer:	The 2TB, 4TB, and 8TB drives are all SMR, which means they are slow for random writes and not suitable as boot drives. (Google "Why SMR drives are sub-optimal for write-intensive workloads".)
Question:	Is this really 7200rpm? the model number suggests otherwise
Answer:	I got the ST4000DM004 which claims 7200 rpm on amazon and my computer is reporting it has a media rotation rate of 5425 rpm
Question:	Is a sata cable included in the package
Answer:	Cables not included. You can buy a SATA data cable and likely the appropriate power cable for your computer right here on Amazon. Depending on your power supply, the power cable may already be connected to it in your computer -- some have that and some do not.
Question:	Is this 7200 or 5400rpm
Answer:	Only the 1 TB (#ST1000DM010) and 2 TB (#ST2000DM008) models are 7200, all the larger models are 5400. Both the llisted speed and model number change in the product description as you pick different disk size options. This is consistent with Seagate's website -- From the home page, drill down through (or search for) Internal / Hard Drives / BarraCuda - Learn More, and then click the 3.5 inch models tab (NOT the 3.5 inch PRO models tab). Then click on the data sheet next to any model to get a PDF with a table containing all of the models along with their drive speeds and other specs..

Is This Book for Me?

This book is for developers new to quantum programming as well as those who may have read and heard about this technology and are looking for a quick way to get started. This book will also be helpful to students who are studying quantum computing at university. They’ll find that the topics covered in this book complement their classroom lectures. I don’t expect you to have any background or previous exposure to quantum mechanics or quantum programming. I’ll introduce you to the relevant concepts and help you gain the necessary dexterity. But I do expect that you know how to program using any one of the multitude of high-level languages available today, such as C#, Java, JavaScript, Objective-C, Python, and so on.

Although you don’t need to know assembly language programming, you should at least be familiar with the notion of Boolean gates and logical operations, and the fundamentals of complex numbers, basic trigonometry, and vector and matrix operations, such as multiplying them and finding their inverses.

See Appendix 1, ​Mathematical Review​, to brush up on these subjects. You’ll need to know these topics to apply advanced quantum effects in your programs from Chapter 6, ​Designer Genes—Custom Quantum States​, onward.

User questions & answers

Question:	Can I boot from this drive on a mac? In other words, is it bootable
Answer:	Mounting the drive is easy on a Mac, unless it is NTFS or another format. Booting is not (realistically) possible. It's a backup drive and would be terrible and break fast anyway. Trust me, usb bootable drives are the wrong way to go. Get a thunderbolt 3 drive to boot from, those work significantly better.
Question:	What cable will I need to get to connect this to a usb3 port
Answer:	It comes with cable for either 2 or 3
Question:	is this drive's usb interface support usb
Answer:	USB 3.0/3.1/3.2 is backward compatible with USB 2.0. USB 2.0 supports a lower power output, which may be insufficient for this drive, so if WD says a 3.0 port is required...it likely is.
Question:	How is it different from other WD drives sold for
Answer:	The 99 dollar models transfer on my computer at around 90 MB sec, bought this USB-c model without realizing it was different, only transfers at 35 MB sec on same computer, considerably slower for more money, stay away.

User questions & answers

Question:	What are the differences between the 5 price options
Answer:	The price options are for different products; built to hold larger vs. smaller capacity drives. Understand what you want/need and then order the product that meets your need. I have the smallest capacity drive and it works great for what I wanted.
Question:	Does it work with windows to go
Answer:	I would bet probably so. Windows-to-go is dependent on your hard drive choice, but I have seen it work when "it really shouldn't". Where most people get sidelined is not the drive choice but the bios/setup settings on the pc/laptop/etc device. The variance among them is huge.
Question:	Can this unit be opened once it's used? I don't want to break it to replace the drive inside
Answer:	I open mine from time to time and change out the drives. Someday I will buy more of these boxes and won't have to do that, anymore. It is easy. Requires no tools.
Question:	I only have usb 2.0 on my old computer. will this power up and run okay with usb 2.0? thanks
Answer:	Those ports marked for charging a cell/tablet have the Wattage ability for the powerful magnetic coils in a fast mechanical hard drive; Such as Seagate-brand Baracuda, it's 7,200RPM. driven. If "official" 2.25Watts port, then inject more by spare cell-charger inserted into the side of 'droid On-The-Go OTG pigtail...about five additional Watts from that charger

User questions & answers

Question:	Is this drive smr if so i don't want it
Answer:	No, it’s not. All Ironwolf and Itonwolf pro drives are SMR free, according to Seagate
Question:	Does any one know a case where 3 could fit inside
Answer:	I have 3 of these in a Synology 4 bay NAS DiskStation DS918+ works great!
Question:	I purchased (2) 12-tb: anyone knows why i get 10.91-tb for each? why are we short
Answer:	manufacturer considers 1 Megabyte to be 1000 Kilobytes, 1 Gigabyte to be 1000 Megabytes, 1 Terabyte to be 1000 Gigabytes and so on. This is correct considering that kilo means 1000 and mega means 1000000 (10^6). However, computers calculate on base 2 and to them, 1 MB is actually 1024 kilobytes, 1GB is 1024MB and 1 TB is 1024GB. This difference in the method of computation is responsible for this "missing space." Let's take an example of a 500 GB hard disk. From a manufacturer's point of view, the 500GB will have 500*1000*1000*1000 = 500000000000 bytes. From a computer's point of view, 500GB is actually 500*1024*1024*1024 = 536870912000 bytes. So, a hard drive that promises to have 500 GB storage space will actually display 465.66GB, 536870912000-500000000000 = 36870912000 bytes (34.34GB) less storage space when connected to a computer. This is true of every drive you buy
Question:	Can this be used as a normal hdd storage drive for a desktop pc
Answer:	I have two NAS drives in my computer, and they work great. I bought two easystore external hard drives and removed the hard hard drives from the case. The hard drives are 5400 rpm drives. I only archive things on those drives, and they work great. The 7200 rpm drives are better for gaming but more expensive. The easystores only costed me $150. They also have a 256mb cache.

User questions & answers

Question:	Can I plug this in as an external hdd enclosure with usb 3.0 capabilites and have it function on an xbox one
Answer:	Yes, the only requirement on the Xbox One side is that the connection be USB 3.0 and the drive be a minimum of 500 Gb. Other than that purchase a reliable enclosure kit that also supplies power and uses the SATA connection already on the HDD.
Question:	On the picture it shows the hard drive's insides, do I need a special enclosure besides me computer case for this
Answer:	If your are installing in a Windows PC, that is a new-ish computer (probably any that came with vista and many that came with XP) it will support Serial ATA hard drives, open abbreviated to SATA drives. You should look up the specs on your computer to insure compatibility. This hard drive is a SATA drive so it will install and replace your other computer. I purchased this drive, and also bought an external case. This would allow this internal hard drive to work as an external drive. It plugs into an external power supply and connects to the computer with a USB cable. The external case I purchased here on amazon is a: Sabrent USB 3.0 To 3.5-Inch Sata Aluminum Hard Drive Enclosure Black Case.I was installing Windows 7 on my PC. I stalled the WD 1 TB drive in the PC, installed the Windows 7 software, then installed my older smaller drive in the external case.
Question:	Is this the retail version (boxed) or is it an OEM bulk drive
Answer:	What do you think you get for $86/4TB? It's OEM without a warranty. If you want that spend $20 more for 2 years with the retail version. For my use I don't need a warranty anyway, odds are it will fail decades from now since I use these as storage mostly sitting unpowered on a shelf 95% of the time (with LTO backups just in case I'm unlucky). The 4 in my PC are the same drives in an 8TB raid1, and they have been spinning 24-7 for 3 years now with no HDD replacement needed.
Question:	Which 1 TB hard disk you recomend between the Western Digital Blue WD10EZEX or the Seagate Barracuda ST
Answer:	I have bought and used WD and Seagate hard drives. I have never had an internal WD hard drive fail on me yet, but I have had one of their older Elements external hard drives fail on me. As for Seagate, I purchased an ST2000DM001 (which is the 2tb version) several months ago that has now failed. I lost everything and got a clicking sound, as if it were stuck. Only lasted 5 months. In comparison I have had my 1st WD blue WD10EZEX for more than two years now and I have not had a failure at all. It's extremely reliable, so much so I decided to replace the Seagate one with a another one of the WD10EZEX's. I have 4 hard drives in my computer 1 SSD (For operating system), 2 WD Blues 1tb and an older Seagate one from an older computer (a dell dimension) with about 250gigs of capacity. I'm planning on getting another blue or black 1 tb to replace it later. I definitely would recommend the blues. It's not that expensive, it's reliable and comes with a decent warranty. I would not recommend Seagate. Just can't trust it. No matter what hard drives should last past the warranty, not even a year and it fails? What kind of QC are they having at Seagate?
