Question Hello, I have a 2017 iMac whenever I try to open any app I see spinning wheel for few seconds pretty much every time.Time Machine is a very good inbuilt backup software for MAC that can be used to backup MAC for free. Best Malware Removal and Protection SoftwareHello a 2017 iMac 21.5 8GB Ram and 500gb HDD question. Buffalo TS51210RH NAS Firmware 3.03 CATEGORY: Moreover, it would be best if you take into account using a UPS unit (Uninterruptible Power Supply) to perform this task, because no power disruption should affect the upgrade.

Best Hdd 2017 Portable Hard DriveWeighing the Need for Speed: Hard Drive or SSD?This portable hard drive is great for students and people who use Mac products every day as it is specially formatted for Mac. You can also choose the option to backup at a particular instant.This guide will help you make sense of all these and many more questions that arise while you're shopping for an external hard drive. Option is provided to delete older backups on your own.External SSDs offer at least twice that speed and sometimes much more, with typical results on our benchmark tests in excess of 400MBps. Unlike a conventional disk-based hard drive, which stores data on a spinning platter or platters accessed by a moving magnetic head, an SSD uses a collection of flash cells—similar to the ones that make up a computer's RAM—to save data.Just how much faster is it to access data stored in flash cells? Typical read and write speeds for consumer drives with spinning platters are in the 100MBps to 200MBps range, depending on platter densities and whether they spin at 5,400rpm (more common) or 7,200rpm (less common). Need a backup option or just more space Here are our top picks for external storage options.Hard drives may get you more capacity for your dollar by far, but first you need to consider a major difference in external storage these days: the hard drive versus the SSD.Solid-state drives (SSDs) have fewer moving parts than traditional hard drives, and they offer the speediest access to your data. (Of course, in this scenario, your files are going to have to stay at your desk.)A desktop drive with a single platter mechanism inside will typically use a 3.5-inch drive inside and comes in capacities up to 12TB, though a few 16TB single drives in external chassis have started to emerge. We define these as having one or more spinning-platter drives inside and requiring a dedicated power cable plugged into AC power to work. In that case, your best option is a desktop-class hard drive. Their total storage capacities are limited only by their number of available bays and the capacities of the drives you put in them. Their defining characteristic is the ability to swap drives in and out of their multi-bay chassis easily, so most provide quick access to the drive bays at the front of the device.Most such multi-bay devices are sold without the actual hard drives included, so you can install any drive you want (usually, 3.5-inch drives, but some support laptop-style 2.5-inchers). They're mostly intended for professional use in editing studios, surveillance control rooms, and the like. In the case of these and single-platter-drive products, you're not meant to swap out the drive or drives inside.The largest desktop drives are often much, much bulkier than the first two categories, so big that you'll want to stick them under your desk or in a dedicated server closet. These larger models are more expensive but also much more capacious—think 16TB or more (in that case, populated by two 8TB drive mechanisms). In addition to storing large media collections, these drives can also serve as inexpensive repositories for backups of your computer's hard drive that you schedule, using either software that comes with the drive or a third-party backup utility.The next size up for consumer desktop drives is about the same height but twice as wide, to accommodate more than one platter-based hard drive mechanism in the chassis. Example: A $60 1TB (1,000GB) hard drive would run you about 6 cents per gigabyte, while an $80 2TB (2,000GB) drive would work out to about 4 cents per gigabyte. As a rule, portable drives get their power from the computer to which you connect them, through the interface cable, so there's no need for a wall outlet or a power cord/brick.The best way to gauge relative value among similar portable drives is to calculate the cost per gigabyte, dividing the cost of the drive in dollars by the capacity in gigabytes to see the relative per-gig price. Any portable platter-based hard drive should fit easily in a purse or even a coat pocket. These are called generically "2.5-inch drives," though they are actually a smidge wider than that. Hard drive-based portables make use inside of the same kinds of platter-drive mechanisms used in laptops. (See our separate roundup of the best NAS drives.)At the other end of the physical-size spectrum are portable drives. Messagecom app for mac( Thunderbolt 4 is emerging here in 2021, but drives that use it and PCs that support it are not yet common.) All late-model Apple MacBook Pro and MacBook Air laptops have them, and many high-end Windows 10 laptops do, too. These connection types are ever in flux, but these days, most external hard drives use a flavor of USB, or in rare cases, Thunderbolt.Right now, the fastest mainstream connection type is Thunderbolt 3, which is handy assuming you have a newer laptop or desktop with a Thunderbolt 3 port. Which Interface Should You Look For?How an external drive connects to your PC or Mac is second only to the type of storage mechanism it uses in determining how fast you'll be able to access data. Some require you to sacrifice raw capacity for data redundancy, so you'll want to pay attention to the nuances of each level. Hit the link above for an explanation of the traits and strengths of each RAID level. Depending on which RAID level you choose, you can prioritize capacity, speed, or data redundancy, or some combination thereof.A collection of spinning drives configured with a RAID level designed for faster data access can approximate the speeds of a basic SSD, while you should consider a drive with support for RAID levels 1, 5, or 10 if you're storing really important data that you can't afford to lose. For ordinary external hard drives, Thunderbolt is very much the exception, not the rule. USB-C: What's the Difference?)You'll only see the speed benefits of Thunderbolt 3, however, if you have a drive that's SSD-based, or a multi-drive, platter-based desktop hard drive that is set up in a RAID array. (See our explainer Thunderbolt 3 vs. As a bonus, a desktop drive that supports Thunderbolt 3 might also come with additional DisplayPort and USB connections that allow you to use the drive box as a hub for your keyboard, mouse, monitor, and other peripherals. If the drive includes only a single cable, you may need an adapter, depending on your computer's available USB ports. USB ports are ubiquitous, and many external drives now come with cables with both rectangular USB Type-A connectors and oval-shaped USB Type-C ones to enable adapter-free connections to PCs that have only one type. Almost every recent drive we have reviewed supports USB, and the same goes for laptops and desktops.
