So whereas the LinkStation is an effective possibility for extra skilled house or enterprise customers who already know a bit about NAS drives, it’s most likely not the most suitable choice for first-time customers who’re nonetheless studying the ropes.
How to decide on a NAS drive
Listed here are some important options it is best to look out for when deciding on a NAS drive on your Mac.
macOS compatibility and Time Machine assist
One of many nice unsung options of macOS is Time Machine, the software program that sits inside your System Preferences panel and quietly performs an automated backup of the complete contents of your Mac’s arduous disk each hour, on the hour.
When you by chance delete a file you’ll be able to return and take a look at all of the earlier variations of that file that you just backed up up to now. And in case your Mac begins behaving oddly and also you assume you might need been contaminated by malware, you’ll be able to simply reboot your Mac and use Time Machine to revive the complete macOS to an earlier, untarnished state.
However, after all, to be able to use Time Machine you do have to have an exterior arduous drive related to your Mac that may retailer all of your outdated backups. Exhausting drives are fairly low-cost nowadays, however as all of us begin to personal an increasing number of desktop computer systems, laptops and cell gadgets, it begins to grow to be each costly and fairly impractical to purchase a separate backup drive for each single machine in our house or workplace. The reply to this drawback is a NAS drive.
Most NAS drives are ‘Mac-compatible’ – however not all of them are what we would name ‘Mac-friendly’. For example, not all NAS drives will permit you to use Time Machine to make backups over the community, so assist for Time Machine is a key function that it is best to verify on when interested by shopping for a NAS drive to be used with a number of Macs.
Consumer accounts and sharing
One other essential function is the power to create particular person person accounts, so that every individual in your house or workplace can have their very own personal space on the NAS drive for storing their private recordsdata. And, on the similar time, it’s additionally useful to create ‘shares’, that are like public folders that may be shared by everybody – maybe for storing music or images for the entire household.
Most NAS drives will permit you to do that, however typically you want a little bit of community know-how to determine how every drive handles this course of (and a few drives, akin to Apple’s now-discontinued Time Capsule, simply ignore this aspect of issues altogether and concentrate on the essential job of dealing with Time Machine backups).
Cell machine assist
And, after all, you’ll additionally need to verify that your new NAS drive supplies an app on your iPhone or iPad. Most of us now have a tendency to make use of iCloud for backing up images, movies and different recordsdata from our cell gadgets, however it may give you further peace of thoughts to know that you just’ve bought a spare backup in your NAS drive in case something goes fallacious.
NAS drive may even allow you to share your images and movies with different individuals by streaming them to cell gadgets over your community, or probably even present a distant entry possibility that means that you can retrieve recordsdata over the web once you’re away from house (a function that producers usually discuss with as a ‘private cloud’).
File streaming
Many individuals additionally use their NAS drive as a type of central media server for his or her house, maybe streaming music and movies to a video games console that’s related to their TV within the entrance room. Mac customers ought to verify to see if a NAS drive can stream recordsdata to an Apple TV, or act as an ‘iTunes server’, storing your iTunes/Music library on the NAS drive in order that it may possibly stream music to each Mac or iOS machine on the community.
How a lot storage do you want?
That’s one thing you’ll have to resolve for your self, however it’s value mentioning that some NAS drives are extra versatile on this level than others.
Among the cheaper NAS drives are offered with a built-in arduous drive—typically a minimum of 2TB—however the arduous drive is mounted and might’t get replaced as soon as it’s full (though the NAS drive might have a USB port that allows you to join a traditional USB arduous drive to be able to add some further storage). That is the best possibility, favored by most house customers and small companies, because it means you’ll be able to simply unpack the NAS drive and join it to your router to get began.
Choosing the proper variety of drive bays
When deciding on a Community Hooked up Storage (NAS) machine, two of essentially the most vital choices you’ll make are the variety of drive bays and the RAID configuration. These decisions instantly affect your storage capability, knowledge redundancy, and general efficiency.
The variety of bays in a NAS enclosure determines what number of arduous drives (HDDs) or solid-state drives (SSDs) you’ll be able to set up. This selection is dependent upon your present storage wants, plans for future enlargement, and your required RAID setup.
Two-Bay NAS: A two-bay NAS is a standard place to begin for house customers and small companies. It permits for a fundamental RAID 1 configuration, which mirrors knowledge throughout two drives for redundancy. This implies if one drive fails, your knowledge is protected on the opposite.
4-Bay NAS: A four-bay NAS is usually really useful for individuals who want extra storage, akin to professionals, content material creators, or small workplaces. With 4 bays, you should use extra superior RAID ranges like RAID 5 or RAID 6, which supply a stability of storage effectivity and safety in opposition to one or two drive failures, respectively. Some four-bay fashions can assist as much as 80TB of storage and should provide enlargement modules so as to add much more bays later.
Bigger NAS Models: For extra demanding necessities, NAS gadgets with six, eight, or extra bays can be found, providing large storage potential—as much as 256TB in some circumstances.
Many NAS gadgets are offered “unpopulated,” that means you should buy the drives individually. This supplies the flexibleness to decide on your personal drives and improve them sooner or later.
Deciding on a RAID Configuration
RAID (Redundant Array of Cheap Disks) is a expertise that mixes a number of drives right into a single logical unit to enhance efficiency or present knowledge redundancy . The RAID stage you select is usually dictated by the variety of drives you may have and your priorities for velocity versus knowledge security.
Listed here are some widespread RAID configurations supported by NAS gadgets:
RAID 0 (Striping): This configuration combines two or extra drives to maximise efficiency and capability . Knowledge is “striped” throughout the drives, resulting in sooner learn and write speeds . Nevertheless, RAID 0 provides no redundancy; if a single drive fails, all knowledge within the array is misplaced . It’s best fitted to duties the place velocity is paramount and knowledge is backed up elsewhere .
RAID 1 (Mirroring): This setup requires a minimum of two drives and creates an actual copy (or mirror) of your knowledge on every drive . It supplies wonderful knowledge safety, as you’ll be able to merely change a failed drive and rebuild the array . The trade-off is that your usable capability is just half of the entire uncooked capability of the drives .
RAID 5: Requiring a minimal of three drives, RAID 5 stripes knowledge throughout the drives together with parity info . This permits the array to resist the failure of a single drive with none knowledge loss . It provides stability of efficiency, storage effectivity (you lose the capability of 1 drive for parity), and redundancy . Reads are sometimes quick, however writes could be slower because of the have to calculate and write parity knowledge .
RAID 6: This stage is just like RAID 5 however requires a minimum of 4 drives and makes use of twin parity . This implies it may possibly tolerate the failure of as much as two drives concurrently, providing even better knowledge safety .
RAID 10 (or 1+0): A hybrid RAID, this configuration combines the mirroring of RAID 1 with the striping of RAID 0 . It requires a minimum of 4 drives and supplies each excessive efficiency and redundancy, however at the price of utilizing solely 50% of the entire drive capability .JBOD (Only a Bunch of Disks): This isn’t a real RAID stage. It merely combines a number of drives right into a single massive quantity with none efficiency or redundancy advantages
Selecting between HDDs and SSDs
Whereas conventional HDDs are essentially the most cost-effective answer for bulk storage in a NAS, SSDs are additionally an possibility .
HDDs: Exhausting drives provide massive capacities at a decrease value, making them superb for storing massive media libraries or backups. It’s essential to make use of drives particularly designed for NAS use, as they’re constructed for steady operation and are extra immune to vibration. Nevertheless, remember that some recording applied sciences, like SMR (Shingled Magnetic Recording), are unsuitable for RAID configurations and might trigger errors.
SSDs: Stable-state drives provide considerably sooner efficiency and are quieter than HDDs. Nevertheless, they’re costlier and sometimes have decrease capacities, maxing out round 4TB for NAS-specific fashions . Some NAS gadgets permit you to use NVMe SSDs as a high-speed cache to spice up the efficiency of an HDD array.
The unpopulated possibility
Nevertheless, many NAS drives are offered ‘unpopulated’—with none inner arduous drives already put in—and easily present two or extra empty drive bays into which you insert your personal selection of arduous drives. This feature is costlier, however it means that you can customise the NAS by shopping for your personal arduous to be able to present as a lot storage as you want. And, if you happen to run out of cupboard space, you’ll be able to simply take out the outdated drives and insert new, bigger drives sooner or later.
This sort of NAS drive typically additionally provides quite a lot of ‘RAID’ choices—this stands for “redundant array of unbiased disks”—which use a number of arduous drives to supply further efficiency and knowledge safety.
How we take a look at NAS drives
To guage Community-Hooked up Storage (NAS) drives, our testing course of combines standardized benchmarking with sensible, real-world use circumstances to make sure a complete evaluation.
Our methodology entails a number of key steps:
Benchmarking: We conduct stringent checks and benchmarks on the NAS drives we assessment. This permits us to construct a library of outcomes for direct comparability throughout completely different fashions .
Actual-World Simulation: We mirror on a regular basis utilization by transferring numerous units of recordsdata and folders to and from the NAS machine .
