If you’re looking for a workstation or desktop HDD — after you've picked up one of the best SSDs for your primary storage, naturally — the Toshiba X300 Pro might be your best option. It offers a combination of high capacity, good performance, a solid warranty, and reasonable pricing, making it a good fit for more serious systems. Everybody loves SSDs, but you can’t beat the TB/$ value of an HDD, and you can only get so far with 8TB WD Blacks or Seagate FireCuda hard drives. We'll likely add it to our list of the best hard drives (for certain capacities), as it's good for content creators, developers, and other professionals that need a faster, larger drive that’s built to last.

We previously reviewed the Toshiba X300 14TB , a drive designed in the same vein but with weaker performance and a very limited 2-year warranty. It might suffice if you want more capacity than a standard consumer HDD can provide, but at that point shucking starts to look good. There are plenty of specialty drives that can fit the bill such as those designed for NAS, surveillance, or enterprise use. But NAS drives, like the Toshiba N300 Pro, are usually optimized for multi-drive environments, while surveillance drives will have firmware “AI” optimized for streams and image-related tasks.

Enterprise drives, like the WD Gold 22TB , often have special features like ArmorCache and a higher workload rate limit. All of these drives will work well in a workstation or desktop, but having the option of better performance across a range of capacities can be useful. The Toshiba X300 Pro and Toshiba N300 Pro provide just that, with a more relaxed workload limit in return for a lower price. Right now, the X300 Pro hits the sweet spot at its highest 20TB capacity, but its extra performance and cache at 10TB and up make it an interesting choice if its price matches or beats the N300 Pro in the 12TB–18TB range.

Toshiba N300 Pro Specifications

The X300 Pro is available from 4TB to 20TB but the point of such a drive is capacity, so we’re looking at the 12TB and 20TB models today. Like the NAS-centric N300 Pro, the X300 Pro has 512MB of DRAM cache from 10TB and up, which is more than much of the competition. This can help with many workloads and provides a larger buffer for small writes. Unlike the N300 Pro, the X300 Pro is not optimized for NAS environments with multiple drives but is instead intended for workstations and high-end desktops. It maintains the 5-year, 300TB/year warranty that should be sufficient for such systems.

The X300 Pro is, in effect, equivalent to the N300 Pro, which potentially makes it the better choice for many users at 20TB. It competes directly with the Seagate IronWolf Pro, which currently costs more, but with a lower data write limit than the WD Red Pro, which also costs more. If you're really going to write over 300TB to one of these drives, the WD Red Pro could warrant the added cost, but for most users that's a non-issue.

As always, it’s important to keep an eye on prices and settle on a desired capacity. If you need more than 10TB you can’t rely on general consumer drives. You can potentially shuck external HDDs , but if you want a more reliable solution, the X300 Pro could be a good choice.

Software and Accessories

Toshiba is more focused on getting the drive to your door than providing a full suite of software — software that's often unnecessary and unwanted for a lot of people. There are a plethora of free and paid applications available to monitor and maintain your storage drives. While toolboxes or Acronis True Image — or their equivalent — are nice to have as downloads, they're more useful for less-professional storage solutions.

The X300 Pro is designed for content creation and workstation use where management will be more rigorous. This does mean that the X300 Pro should undercut the competition a bit on price, though. Looking at current prices, the 20TB model hits the mark at just $17.75 per TB, while the 12TB model costs more than the IronWolf Pro 12TB.

A Closer Look

Toshiba helpfully includes a table on the back of the product box comparing the N300, N300 Pro, X300 , and X300 Pro. The X300 technically fills the same role as the X300 Pro, but it has a much weaker warranty and no guaranteed workload rate limit. We were underwhelmed by that drive's performance, but we were happier with the N300 and N300 Pro.

The X300 Pro matches up well against the latter, which is designed for multi-bay NAS. If you're just looking for a single drive and don't intend to run it in a NAS, the X300 Pro should be a good choice for serious machines that need high storage density.

Toshiba’s color coding has a silver or gray label for workstation HDDs in contrast to a dark beige or tan for NAS. The hard drive is otherwise unexceptional, although we point out that the 12TB does have 512MB of DRAM cache. The IronWolf Pro and Red Pro are stuck with 256MB at that capacity. Those two drives - the IronWolf being the 300TB/year SKU - also have a sustained transfer rate cap of 240 MB/s while the X300 Pro should be able to match the 12TB N300 Pro’s 281 MB/s. These attributes can give Toshiba a leg up with performance at certain capacities which is why we liked the N300 Pro at 12-18TB, but as always it comes down to price.
