However, this is not quite as cut and dry as it appears. Indeed, you can even expand a RAID 1 to a RAID 5 on a 2-bay but spreading it over both the NAS and expansion enclosure at once, to provide an excellent way to still increase the storage on your 2-Bay later on and not feel trapped within its dual media design architecture. Additionally, these days a number of brands provide the same level of external enclosure expandability on both the 2-Bay and 4 Bay NAS systems (eg DS920+ / DS720+ and TS-253D / TS-453D), therefore 2-Bay NAS does not have the lower metaphorical glass ceiling that it once had in terms of additional storage down the line. Yes, you could fully populate a four-Bay NAS with 4TB hard drives, but you could always just use a single 12TB hard drive at a lower price per TB in 2021 and regardless of whether you use RAID 0 or RAID1 with two disks, still have a huge capacity in a 2 Bay NAS. How on earth can a NAS device that is 50% less in media bays possibly compete?!? Well, in recent years the largest available capacity in hard drives has massively increased and therefore the total potential terabytes available for each media bay has grown drastically. On the face of it, it seems pretty obvious that a 4-Bay NAS model with its increased storage bays will be the better storage option overall. 2-Bay vs 4-Bay NAS – Storage, Expandability and Capacity So today I’m going to talk to you about the differences between each, which one is the best value, their advantages and hopefully help you decide which one best suits your storage needs. With the majority of NAS brands out there offering most standard solutions and across different hard drive scales, choosing between these different sized NAS is not as straightforward as one might think. One of the first hurdles that many users encounter when choosing their first NAS drive is choosing between a 2-bay NAS and 4-Bay. Network-attached storage NAS has evolved rapidly over the years and now there is a tremendous range of solutions that vary in size and ability to choose from, often resulting in the most expensive servers not always being the most capable. Check your wallet (and PCWorld’s guide to the best SSDs) and make the call.Choosing Between Buying a 2-Bay or 4 Bay NASįor many users who decided to make the switch from subscription-based Cloud services and to their own private NAS server, it can be tricky to understand exactly what they need in terms of storage and power. But a 35 percent premium is hefty for a drive that’s not all that much faster than its rivals. If you want the fastest M.2 NVMe SSD available, that’s the Samsung 970 Pro-no ifs, ands, or buts. And the CrystalDiskMark 4K results with various thread and queue depths clearly indicate that performance is well-balanced for most end-user workloads. It was hardly a blow-out, but the Samsung 970 Pro proved fastest in nearly all the tests we ran. There is a very large margin of variation in this test. ![]() ![]() The 970 Pro was a bit slow in the folder write, but dominated in all the other tests. Our real world copy tests, shown below, are designed simply to back up the conclusions of the synthetic benchmarks, and spot if there are any major drop-offs during heavy end-user scenarios. The 970 Pro didn’t win all the AS SSD tests, but it proved the better drive overall. Unfortunately for the 970 Pro, the 970 Evo’s street price is also lower too now with the 500GB drive at $200 and the 1TB version at $400. If you’re bargain hunting, stop teasing yourself with this review and go read about those. The good news is the 970 Pro’s actual street price is a good clip lower at $250 for 512GB and $500 for 1TB. That’s a difference of around 35 percent. ![]() The Samsung 970 EVO, also announced today, and the WD Black NVMe, cost around $100 less per 500GB of capacity. So if you want the 970 Pro (admit it, you do) you’ll be choosing from the $330 500GB version or the $630 1TB version. With SSDs, fewer chips means fewer paths to shotgun data across, often resulting in slower write and read performance. There’s also no 250GB version, though that’s likely for performance reasons. But the upshot of using faster, less data dense (compared to 3-bit TLC) MLC NAND is that there’s no 2TB version of the drive. The drive uses Samsung’s 64-layer MLC NAND, and the company’s new Phoenix controller to make good use of it. Don’t bother with this drive unless you have those four lanes. “Up to” means it’ll use them if you’ve got them, but can still function with two, albeit at about half the speed. The 970 Pro is a M.2 2280 (22 millimeters wide, 80 mm long), NVMe drive that can utilize up up four PCIe 3.0 lanes. ![]()
