Backup your Mac with a portable or desktop hard drive.My general question is: can a computer that has some of its storage on an external drive with a fast connection (such as Thunderbolt) perform as well as a computer with the same amount of storage inside the computer?Take a look at our dependable external hard drives and SSD’s for backup, storage, and gaming, from desktop to portable use.

LaCie 2TB Mobile Drive External Hard Drive USB-C - Previous Gallery Image Discover the world of portable hard drives for Mac.If I bought an external Thunderbolt SSD for about £220 per terabyte, would I be likely to see any difference? David5 Internal SSD (SDSSDH3-1T00-G25) at the best online prices at eBay. Apple can supply the unit with up to 2TB of solid state drive (SSD) storage, but charges an eye-watering £720 per terabyte. I am considering upgrading to the latest 2018 version, but I need at least 1TB of storage. To be specific, I have a 2014 Mac Mini, which is very slow. Sleek contemporary design, universal. Quick USB-C, USB 3.0, and Windows/Mac compatibility.
Best External Hard Drive 2015 Mac With AIf speed is critical – which I doubt – then a 2TB internal drive will be faster than a 128GB or 250GB internal drive in the same class.An external SSD’s real-world performance will also depend on many other factors, including the type of storage and the interface chips used. However, you should be aware that big SSDs are faster than small SSDs, because the controller can write to more modules at the same time. While you could have a faster external drive, it would be better to spend the money upgrading the internal drive, where possible.The specific question is impossible to answer because there are so many variables. The general question is easy: external drives are slower than comparable internal drives, because the interconnection itself adds an overhead. ![]() In general, fast, expensive storage lives as close to the processor as possible, with the ultimate being cache memory that is actually on the CPU.

The storage hierarchyExternal drives are the answer for adding more storage on the cheap to most laptops, but also desktops that are difficult to upgrade. A real-life throughput of around 2,750MBps makes it potentially faster than most internal SSDs, and not far short of the 1TB SSD in the 2018 Mac Mini.Note that the serial connection speeds, given in Gbps, represent the maximum bandwidth, not the actual throughput. Thunderbolt started at 10Gbps, with a throughput of 700MBps to 800MBps, and today’s Thunderbolt 3 is specified for up to 40Gbps or 5,000MBps of bandwidth. USB 3.0 and USB 3.1 Gen 1 connections have a theoretical bandwidth of 5Gbps or 640MBps, and typically provide 300MBps to 400MBps of throughput, while USB 3.1 Gen 2 can manage twice that.Thunderbolt connections are even faster. SATA II interfaces can handle up to 3Gbps ( gigabits per second) or 375MBps ( megabytes per second), while SATA III can manage 6Gbps or 750MBps.After that, there are external hard drives that use either USB (Universal Serial Bus) or Thunderbolt connections. There are fast flash memory cards that slot directly into the computer’s main board, and internal SSDs and hard drives that use Serial ATA connections. These storage systems are very cheap, very slow, and a very long way from the CPU.There are lots of options between these two extremes. Dvd burner driver for macThunderbolt 2 was fast enough to cope with multiple SSDs, but turned out to be a bottleneck for NVMe-based SSDs. We needed SATA III and USB 3.1 Gen 2 to cope with those. For example, SATA II and USB 3.0 were fast enough for traditional hard drives but turned out to be a bottleneck for faster SSDs. The specifications always leave some headroom to allow for advances in technology, and sometimes they don’t leave enough. I own a similar WD MyBook, and while it’s comparatively slow, it has no problem playing 1080p full HD videos. You could move most or all of them to a cheap external hard drive.Today, you can buy an 8TB external USB 3.0 hard drive for £143.99, or £18 per terabyte. Data movesSo, the real question is how much data you need to move, and how fast you need to move it.Your operating system and programs should fit on the fast SSD inside the Mac Mini, where they will be instantly available, but what about the rest of your data? If you need 1TB for text files, photos, music, and videos, they don’t need to be stored on a high-priced internal SSD. This doesn’t mean you’re obliged to use external Thunderbolt 3 SSDs, because – as mentioned – the same port supports USB 3 Type C devices as well. Photograph: NurPhoto/NurPhoto via Getty ImagesThe 2018 Mac Mini includes four Thunderbolt 3 ports, which are relatively rare on Windows PCs. If you won’t actually use the 2,750MBps that Thunderbolt 3 can deliver with a fast NVMe SSD, why pay for it? Why Thunderbolt 3?Thunderbolt 3 uses the same plug as USB-C but facilitates significantly faster connections. (I don’t have anything like that many, but if I did, they would fit on an 8TB drive.)Faster options include USB 3.1 Gen 1 and Gen 2 SSDs (with Type C plugs that fit into Thunderbolt ports), SATA III SSDs (which fit into standard drive bays and external enclosures), and Thunderbolt SSDs.But as I said, you don’t need operating system speeds on a data drive. Thunderbolt 3 is the “get out of jail card” for people who want to use the Mini for 4K video processing or gaming and find the built-in graphics don’t meet their needs.Third, Thunderbolt 3 can support multiple SSDs, which can be daisy-chained together. The new Mac Mini’s major weakness is that it doesn’t have a discrete graphics card – just the Intel Integrated Graphics that come with the processor – and there is no slot to add one. Most users will plug their main screen into the HDMI port, but they can plug another screen into one of the Thunderbolt 3 ports.Second, it means you can plug in an external graphics card or eGPU, which could be a PC graphics card in a suitable enclosure. This is good for high-resolution video and games.Basically, Thunderbolt extends the PCIe connection outside the PC.First, this means you can add a second high-resolution screen to a 2018 Mac Mini. If your PC has a PCIe x16 graphics card slot, it has 16 lanes and can handle up to 16GBps. It delivers maximum bandwidth via a system of bi-directional “lanes”, each of which can carry almost 8Gbps, in version 3. Until it does, the Mac Mini is having to fill the gaping hole for an affordable Mac that doesn’t have a built-in screen.Have you got a question?

Unfortunately, since the demise of the much-loved “cheese grater” or Power Mac G5, Apple hasn’t offered one. If you have four or more, Thunderbolt 3 is the way to go.It would, of course, be much more sensible to buy a proper tower with a couple of PCIe slots for graphics cards and room for multiple internal drives.
