Samsung M3 Portable 4TB

Samsung M3 Portable 4TB


Meet a record-breaking hard disk drive…

While most recent storage breakthroughs have mostly involved SSDs and non-mechanical technologies, hard disk drives still hold most of the world’s data. Also, for the majority of us, they are the only financially viable option for bulk, mass storage beyond the terabyte mark.

The 4TB Samsung M3 Portable otherwise known as the HXM401TCB/G was launched a couple of months ago, and it’s the perfect example of how far spinning, traditional hard disk drives have moved over the past 10 years.

It took 2.5-inch models a mere three years to catch up with their bigger 3.5-inch cousins and while the capacity of the latter only doubled over that period, that of the smaller devices has quadrupled since 2011.


Storage density

Managing to cram 4TB into such a small volume means another thing – the Samsung M3 Portable offers by far the highest storage density of any hard disk drive on the market. The drive measures 82x118.2x19.85mm, which translates into a volume of 192 cubic centimeters and a storage density of just under 21GB per cm3.

Samsung Storage, which was purchased by Seagate a few years ago, managed to offer such a storage capacity by squeezing five 800GB platters into the drive.

While we didn’t manage to pry open the device’s case, the drive used appears to be a Momentus one from Seagate, the ST4000LM016 (AKA Spinpoint M10P), a model that doesn’t even appear on the HDD maker’s website. CrystalDiskInfo states that it has 16MB cache and a rotational speed of 5400RPM.



What it didn’t highlight was the fact it is one of the first, if not the first 2.5-inch SMR hard drive on the market. SMR or Shingled Magnetic Recording is a storage technology that allows more data to be crammed on a platter in a way that’s similar to shingles on a roof (hence the name).

Its biggest flaw though is the fact it is much slower than traditional hard disk drives when having to deal with random writes for small files – one solution would obviously be to compress them into one big one to accelerate the file transfer.

On the outside, the drive is similar to many of its competitors. It sits comfortably in the palm of a hand, has an indicator LED, a flat USB 3.0 connector, but there’s no power button. The Samsung logo adorns the top fascia, which itself sports what the manufacturer calls a durable black design.


Performance

The drive comes with a three-year warranty as well as a number of bundled applications, the main one being Samsung Drive Manager, which comprises AutoBackup – a backup solution, unsurprisingly – SecretZone, a data protection solution, Secure Manager, a secure external HD management solution and Samsung’s External HD management tools.

It was one of the better performers on PCMark 8 in recent memory and easily the best 5400PM portable drive we’ve seen for a long time, its score of 2139 being fractionally higher than that of the 3TB Toshiba Canvio.

This drive is surprisingly affordable, managing to offer one of the cheapest cost per TB of this category. The Samsung M3 Portable is a flagship device that is affordable, and relatively fast despite using SMR, plus it has enough storage capacity to fit a billion songs (or MP3 tracks). We couldn’t fault its design and it comes with an adequate software package. In fact, there’s hardly anything to dislike about this drive. Once you understand the way SMR works, you can’t really criticise the poor performance for random writes.


Verdict

The Samsung M3 Portable is a fantastic product despite its slightly boring appearance. Seagate has keenly priced this SMR-capable drive and its sheer value for money should make it popular among those craving for storage. Seagate’s own Backup Plus 4TB USB 3.0 drive might be its only real competitor. Since they probably share the same drive, it is likely that they will perform similarly. That drive is slightly more expensive but comes with a useful Mobile Backup App and two years’ subscription to OneDrive cloudbased storage with 200GB. That’s worth $4 a month or $96 over the duration of the subscription.

Note that this drive is also available as the P3 Portable with a slightly different form factor. This sample was provided by Samsung and as always (and especially with drives of this capacity), we would strongly urge you to back up your hard disk drive.

CONCLUSION:

This drive is a must-buy if you’re looking for a reliable storage device for files and backups.
