What are the RW speeds of my dv7 optical drive (Blu-ray player & SuperMulti DVD burner)?

I am struggling to understand what capabilities my optical drive actually has; I am clear on CD/DVD/BluRay. The spec indicates "hp BDDVDRW CT40N", but when I search it, nothing pops up. I want to record data, like backups, and would like to know recording speeds so I can purchase the appropriate blank DVD's

It is made by LG and has these speeds:
Key Feature:
Write Speed:
DVD±R     8X
DVD±R DL 4X
DVD-RAM    5X
DVD-RW     6X
DVD±RW    8X
Read Speed
BD-ROM :Max 6X CLV
CD    24X
DVD   8X
As you can see, BD media is read only and you can use any kind of writable DVD media on the market.

T23 - What are the plastic side rails & adapter needed for drives to fit in the Ultrabay?

Does anyone know the part numbers for the plastic side rails and adapter required to be attached to a bare CD or DVD drive in order for it to fit in the Ultrabay and connect? I have a bare Sony DVD RW replacement drive with the correct "notched" bezel. I know most people just strip off the adapter and plastic side rails from an existing IBM/Lenovo Thinkpad CD drive and put them on the new drive. But I was wanting a second set to I could keep both the T23's (a 2647) DVD CDR original drive and the new DVD RW drive.
Life is just one big "Beta Test"

I've never run into part numbers (i.e., FRU) for the Ultrabay rails and I've changed out my fair share of them. What I basically do is buy "dead" or "parts" optical drives off of eBay and then scavenge the rails and IDE connector. I believe that there are at least two very slightly different designs; the thickness of the side rails is what changes. It's never gotten to the point where the re-fitted drive doesn't fit into the Ultrabay but, depending on the drive and rails in question, there may be too much or too little space inside the bay. Also, you should be careful when transferring screws from one drive to another. I've found that on some drives, if the rear screws (the ones which hold the connector on the back of the drive) are slightly too long, then that can prevent the tray from closing.

T530, what are the sata speeds?

Does anyone know if the msata slot in the T530 uses sata2 or sata3 speeds?
Likewise with the main drive bay, and the ultrabay slim sata adapter. Are those sata2 or sata3?
The hardware manual does not specify. I looked.
Solved!

Thanks for the prompt reply.

What are the things required to upgrade internal hard drive For Macbook Pro mid 2012 13 inch?

Hi,
I want to upgrade my internal drive but I don't know how to do that. I have already purchased a WD 1TB internal hard drive. However, I contacted apple support and they said if I try to upgrade the hdd myself, then the warranty of the macbook would be void. I am from India . I currently have a Macbook Pro mid 2012,13 inch.
Also, do i need to download a setup of Yosemite before changing the hdd?
Please guide me
Thanks and Regards
Abhineet Arora

You know what the impact will be on the warranty terms. If you want to install it yourself, look at this video:

It is not very difficult. You will need a #00 Phillips and a #6 Torx drivers.
Ciao.

What are the performance implications moving apps using cloud drive to Azure File Services?

I run a number of cloud services with 5 or more nodes in using cloud drives. Cloud drive is scheduled to be deprecated in 2015. So I am thinking of replacing the cloud drive with Azure Files service.
For each cloud service I am using one storage account to create all the the VHD/cloud drives. Some people at the time when cloud drive first appeared, told me that to get better performance, I should create only one VHD/Cloud Drive
under only one storage account. For example, if I have five instances under a worker role then I should create 5 storage accounts and create one VHD/Cloud Drive under each storage account to be used by each node. I didn't follow that route because I was satisfied
with the performance of the apps under cloud services having all VHD/Cloud Drives under one storage account.
My question is, if I replace cloud drive with Azure file services, will my apps perform well having all shares under one storage account or create one storage account for each share?
Thanks,
@nazik_huq

Thanks Obama for replying.
Here is the comment from @jaiharidas of MSFT if anyone's interested:
@Naziq, It is better to have multiple shares under single storage account and there is no perf implications. However, please ensure that your ingress/egress and request/sec is within
the limits of a single storage account (seemsdn.microsoft.com/.../dn249410.aspx)
and use multiple storage accounts if you need to scale beyond the limits.

What are the advantages of varying write speeds and burn speeds?

What are the advantages of varying write speeds and burn speeds?

The slower the speed, the fewer burn errors (or, in other words, you'll burn fewer "coasters"). I've always tried to burn at a slower speed, i.e. 2x - 4x. I'd rather wait a few minutes more and I've never had any burn errors.

What are the uploads and downloads speeds

what are the upload and download speeds of the time capsule?

what are the upload and download speeds of the time capsule?
If you are asking about Internet download and upload speeds, this is limited by your service plan with your Internet provider.
It might be something like 10 Mbps download and 2 Mpbs upload, for example. That's because on most home plans, the download speeds are typically much faster than the upload speeds....unless you opt for a business type connection at significantly higher cost.
The Time Capsule is capable of much faster speeds than your service provider can ever deliver, so the bottleneck on your network will always be the Internet connection...not the Time Capsule.

What are the speeds like?

Hi guys, im currently on o2 broadband and its slow as and im looking to upgrading to infinity in july when its in my area (guildford) and i want to ask what are the speeds like when playing on xbox live, psn, downloading torrents and downloading from file upload sites such as megaupload ect. most of the usage of our home internet is used as online gaming and downloading from file upload sites. We rarely use torrents.
Thank you!

You would like a Graphic off me???????????? Having said that I've just checked and for some reason Fri & Sat has gone up to 28ms. I've got lots of graph's to show this but it would take up to much space on here. This is my dashboard so you can see.:-

sky twitter account a customer ask why sky go streams are worst then sd and yet bt and eurosports apps stream in hd. Reply from mod, oh thats easy the files for hd are some huge that sky go can't play them and no app can stream hd due to this and so when they say they are they're really sd streams, if there was any way around this we would have done it now.

I have an ipad 2 and when connected to my wifi at home it will not download and play you tube videos quickly. Do I need to upgrade my connenction speed? What is the optimal speed?

I have an ipad2. When connected to my wifi at home it will not download you tube videos for easy viewing. Do I need to upgrade my connection speed? Would 3 Mbps be enought or do I need to go to 6 Mbps. I mainly use my ipad to view emails, browse the internet and watch you tube videos.
thanks - Michelle

Welcome to Apple Support Communities.
There are a number of factors in the 'speed' equation. Any or all of them can affect the 'observed' speed of your connection.
1. Are you in a neighborhood full of WiFi routers (and thus, lots of WiFi interference)? I can 'see' at least 22 other WiFi routers from my living room!
2. What is the maximum connect speed and band and bandwidth available from your wireless router. Is it 802.11n or the older 802.11a/b/g? 300Mbits or 150Mbits? 2.4Ghz or 5Ghz or both? Does your router measure (QoS) Quality of Service and can it change 'channels' automatically?
3. What is the observed strength of your wireless connection? Are you getting at least 80% signal when connected? Are there other people in your family also using significant bandwidth at the same time (Netflix, streaming video, streaming audio, game systems)
4. What is the "advertised" speed of your current ISP connection?
5. What is the measured throughput of your current setup. Go to speedtest.net or use the free speedtest.net app available in the App Store. Try several times, from different locations in your home, and at different times of day and night.
I have AT&T DSL advertised at 3Mbit/sec down and 512Kbit/sec up. My Speedtest.net measured throughput is about 2.4 Mbit/sec downstream and upstream is about 0.4Mbit/sec. I'm using a Motorola Netopia 2210-2 DSL modem. I have no problem viewing YouTube videos and other mobile video content on the iPad 2. I'm connected wirelessly to a D-Link DIR-655 Gigabit router rated at 150Mbps at 2.4Ghz (only) with 802.11 b/g/n enabled. The interior of my home is within a range of 30-50 feet from the router and no more than 1 wall. It is a single level concrete slab foundation of about 1500 sq. ft. with cathedral ceilings. I have successfully streamed ESPN3.com on my MacBook at the same time my son was streaming another ESPN3.com game on his MacBook Pro. I've streamed YouTube videos while my son was watching a NetFlix movie on his Wii game system. He's also successfully used Skype for extended 'teleconferences.' None of my devices are connected to HDMI on a large screen TV. 95% of the time, I can do iChat video without any signal breakup to my son (who is at a college with a Gigabit (1000Mbit) wired connection!). 5% of the time the connection drops. We haven't tried FaceTime (designed for mobile connections to be much less bandwidth-intensive, from what I understand) simply because we both have iChat on our computers.
So for me, a 3Mbit DSL connection is absolutely adequate, given all the other parameters mentioned. As the car manufacturers say, "Your mileage may vary."

Laptop Video Editing: What are the MOST important specs

I've been editing, for a while now, various projects of various lenghts shot on my HV20, on an IMac using Adobe Premiere Pro. Actually, I bought the CS4 Extended Production Suite. It came with OnLocation, which is, I think, a fantastic tool. I really want to be able to record and monitor my future shoots using OnLocation. I've seen how useful monitors and scopes are on set, and the idea of being able to shoot in HD and actually checking the focus on something larger than a few inches is very appealling!
So a laptop is in my future. Now, what are the most important specs?
I could buy 1) a barely used Macbook pro early 08- 17" HD led display ,4g Ram ddr2 ,nvidia 8600M GT 512 VRAM ,800Mhz BUS, 200G 7200HD
and have enough money left to buy an Apple Display 30" refurb
OR 2) a new Macbook pro 17, 4 g Ram ddr3, 512 VRAm, 4g Ram ddr3, double procsessors 9400M+9600M GT 512 VRAM, 1066 BUS, 500G 7200HD
and wait for a second display!
Plus, of course, a portable External Scratch Drive on the Express Card. Now, if that fast drive is handling the footage, could'nt I settle for a 5400HD in the laptop,, they seem much less prone to problems-clicking noise, heat-than the 7200, especially in the new unibody model. Is 800 versus 1066 BUS a terrible trade-off? In terms of secondary displays , I've heard less than lukewarm things about the new Apple 24 LED (glossy is no-no for me).
My intentions are to make documentaries and short fictions as well. I make a living as an actor so I don't need to be performing as a director/editor business wise!
I do want to explore that side of the craft, in a professional and enjoyable way though. I know that, in addition to the laptop, I will get a MacPro in a few years.
Thanks a lot for the inputs!

CPU, RAM, bus speed, system HD, external HD, graphics - basically in that order
You should think in terms of purchasing for maximum future use. In that regard the new 17" MacBookPro is the way to go. The specs are significantly better than the early '08 MacBook and you will be much happier in the long run with performance, software support and longevity.
If you really need a large display, consider a 24" Dell, HP, NEC, etc. in the $200-$300 price range to stay within your total budget. You will be pleasantly surprised how good they are.
You could start out with the 5400rpm system HD - you can replace it anytime with a 7200rpm drive if necessary for hardly any more $ than it would cost in the first place; and replacing it does NOT void your warranty. But you WILL want/need a good external FW800 or eSATA drive (for eSATA you will need an eSATA expressCard/34 however) no matter what.
One other thought, if your primary use will be with an external display, and you don't actually need eSATA capability (FW800 will do you just fine at this point), then the 15" 2.66GHz or 2.8GHz MacBookPro models will be just fine at a significantly lower cost than the 17" model.

What are the best ways to keep my 4 year old iMac going?

I want to put off having to buy a new desktop iMac as long as possible so, while I'm using my 4+ years old iMac, what are the things I should (or should NOT) do to look after it? I know that temperature and humidity must be avoided but here in England (UK) it rarely gets too hot, so what else I should be aware of? Any advice would be much appreciated.

What are the advantages of compressor and it it even necessary

what are the advantages of compressor and it it even necessary?

Necessary for some and not for others – probably a large majority – who can by with the presets avalaible in FCX.
The users who need Compressor are those who want to control the parameters of the encodes to get the best possible trade-off between file size and quality. Or those who want to do things like standards conversions, complex frame speed changes, better re-scaling capabilities, de-interlacing, re-interlacing, output formats beyond which are available in FCX, chapter markers for DVD and Blu-Ray authoring, batch conversions for multiple purposes through droplets, access to clusters for faster rendering.
