#Best nas for mac 2020 update
Once you’ve tuned your NAS to give consistently good results in the first two tests, you can try an incremental update in Time Machine, with the confidence that it should be able to run fairly briskly. Target: excellent results are higher than 90 MB/s anything above 70 is good, but below 50 MB/s suggests a misconfiguration, and less than 30 MB/s is seriously bad. After a pause, the read results will be displayed. To perform the read test, leave those settings the same, click on the Read Folder… button, and select the folder containing the test files that Stibium just wrote. When all the files have been written, the results will be shown in the lower view, and the write speed in the box above. Setting Stibium up is simple: set the middle popup menu to write 0x41 to the test files, ensure the number of repeats is set to 1, the No Cache checkbox is ticked, then click on the Write Series… button and select that folder on the share. This makes it easier to clean up afterwards. This test works with files from 2 MB to 2 GB in size, so more typical of those likely to be transferred when backing up.īefore running this test, I create a folder on the share with a distinctive name such as 0stibiumTest in which to write the test files. Although originally developed to benchmark high-speed SSDs, it works even better on networked storage. Stibium is designed to perform read and write tests on a wide range of storage media. Below 50 MB/s suggests a sub-optimal SMB implementation, and below 30 MB/s suggests a serious misconfiguration which needs to be corrected before testing any further. Target: over 1 Gb ethernet, the transfer speeds should be 70-100 MB/s. Repeat by copying the file in the other direction, from the NAS to your Mac. Work out the time taken in seconds, and calculate (file size in MB)/(seconds to transfer) to give the result in MB/s.

Watch for the moment that copying is complete, and the Finder’s progress window disappears. As the seconds approach 55, drag the test file over a window on your shared folder on your NAS, releasing the file as the seconds reach 00.

Then click the Write Single… button at the top left, and choose where you want the file to be saved. If you wish, you can create a file of an exact size using Stibium: set the file size on the top line to 5 or 10 GB, and the contents to 0x41.
#Best nas for mac 2020 archive
Don’t use a bundle like an app unless it has been archive or compressed into a single file. To do that, create or borrow a single file of that size. This test measures the time that it takes to copy one file of 5-10 GB to the NAS, and copy it back again. Previous versions of macOS may not achieve good performance, particularly when using SMB. Your Mac should be running Monterey, preferably version 12.1.

#Best nas for mac 2020 series
This article proposes a series of simple tests which should help you gain clearer insights into any problem and eliminate causes one at a time. Because there are so many systems and standards involved in backing up to network storage, it’s valuable to test simple functions before trying to tackle the whole series. Many of you report problems backing up to NAS systems, particularly with backups taking forever or throwing errors.
