Exterior 2.5-inch arduous drives have been caught at 5TB of capability for a lot of years, however WD/SanDisk has simply launched a peck of latest 6TB drives, together with the impressively ruggedized and weatherized SanDisk Skilled G-Drive ArmorATD that’s the topic of this assessment.
SanDisk Skilled G-Drive ArmorATD: Options
The ArmorATD is a bulkier-than-usual, exterior 5Gbps 2.5-inch USB arduous drive obtainable with as much as 6TB of capability. On this case, bulk is an effective factor because it gives room for shock absorption and crush resistance (as much as 1,000 kilos/454 kilograms). Although we don’t have the means to check the ArmorATD with 1,000 kilos of stress, the development of the drive leads us to belive the declare. The drive additionally carries an IP54 rain/mud ranking.
A part of the 5.1 by 3.45 by 1.15-inch (13.30 by 8.76 by 2.92 centimenters), 13-ounce (0.37-kilogram) heft of the G-Drive ArmorATD is a silicone jacket that covers the sides, corners, and ends. This features a captive silicone plug masking the USB-C port. WD/SanDisk bundles each USB-C to USB-C and USB-C to USB-A cables so you need to use it on any pc.

SanDisk Skilled G-Drive ArmorATD: Value
That the ArmorATD wasn’t pricier is shocking, given the additional materials required for ruggedizing/weatherizing. It’s solely marginally costlier than the WD My Passport Extremely for Mac and ships in 1TB, 2TB, 4TB, 5TB, and 6TB flavors.
As typical with arduous drives, the worth is healthier per terabyte whenever you go together with the bigger capacities. As of the time of this writing, the 6TB ArmorATD is $230/£226, which is about $38/£38 per terabyte. Nevertheless, the 5TB mannequin is the present candy spot for worth/capability in our estimation–it was $170/£170, which is $34/£34 per terabyte.
SanDisk Skilled G-Drive ArmorATD: Efficiency
Being a 2.5-inch arduous drive, the ArmorATD’s efficiency just isn’t going to look horny in comparison with SSDs. We did use arduous drives for many years and nonetheless managed to get alongside.
The 110 to 140MBps or in order that the ArmorATD reads and writes at is a lot quick sufficient to stream music and audio (a number of streams), file video, and again up utilizing Time Machine or some such within the background. Be aware additionally that the ArmorATD approached 140MBps underneath CrystalDiskmark 8 on the PCWorld check mattress’s USB 3.2×2 port–10MBps sooner than the WD My Passport Extremely for Mac, or the stirringly named “My Passport, Works with USB-C” drive. Issue that into your shopping for calculation.
The Blackmagicdesign Disk Velocity Take a look at numbers for the ArmorATD are barely higher than the My Passport Extremely for Mac, and proper on par for an exterior 2.5-inch arduous drive.
The G-Drive ArmorATD’s efficiency underneath AmorphousDiskMark is about common for an exterior 2.5-inch arduous drive.
Ought to I purchase the G-Drive ArmorATD?
I can’t consider an exterior 2.5-inch arduous drive that outstrips the SanDisk Skilled G-Drive ArmorATD by way of ruggedness, weather-proofing, options, or efficiency. It’s no small fry, nevertheless it’s a journey beast–in the absolute best sense.
See the way it compares to different arduous drives for Mac in our round-up of the most effective.
Macworld: How we check storage gadgets
Macworld runs Blackmagicdesign’s Disk Velocity Take a look at and AmorphousDiskMark 4 with the drive formatted to APFS. However we additionally put drives via sister publication PCWorld’s battery of checks as follows:
IDG storage testing presently makes use of Home windows 11, 64-bit working on an X790 (PCIe 4.0/5.0) motherboard/i5-12400 CPU combo with two Kingston Fury 32GB DDR5 4800MHz modules (64GB of reminiscence complete). Each 20Gbps USB and Thunderbolt 4 are built-in to the again panel and Intel CPU/GPU graphics are used. The 48GB switch checks make the most of an ImDisk RAM disk taking on 58GB of the 64GB of complete reminiscence. The 450GB file is transferred from a 2TB Samsung 990 Professional which additionally runs the OS.
Every check is carried out on a newly NTFS-formatted and TRIM’d drive so the outcomes are optimum. Be aware that in regular use, as a drive fills up, efficiency might lower as a consequence of much less NAND for secondary caching, in addition to different components. That is much less of an element with the present crop of SSDs with their far sooner NAND.
Caveat: The efficiency numbers proven apply solely to the drive we have been shipped and to the capability examined. SSD efficiency can and can range by capability as a consequence of extra or fewer chips to shotgun reads/writes throughout and the quantity of NAND obtainable for secondary caching. Distributors additionally often swap parts. In case you ever discover a big discrepancy between the efficiency you expertise and that which we report, by all means, tell us.
