NAS servers provide a quick, easy and secure means of backing up important data. Compared to a dedicated server, a desktop NAS is considerably more compact, especially two-bay and four-bay models like the QNAP TS-453mini and Synology DS414slim on hand today. The two aren't really direct competitors, so this isn't a straight up Synology vs. QNAP battle, but rather a look at each company's approach to developing compact NAS solutions.
The DiskStation DS1515 is aimed at home users as well as small businesses. Out of the box this NAS can handle five 3.5" hard drives, giving it a maximum capacity of 40TB using the latest 8TB drives, while the addition of two DX513 expansion units boosts capacity to a whopping 120TB.
SSD technology grew stale after saturating the SATA 6Gb/s bus, bringing minor improvements and making up for it with price cuts. With new PCIe and M.2 drives presenting a high performance alternative, it's time for a roundup. We review fourteen of the best consumer-grade SSDs using the SATA, PCI Express or M.2 interfaces and tell you what to buy.
An avalanche of reports started to surface last September when users began to notice that their usually speedy Samsung SSD 840 and SSD 840 EVO drives were no longer performing as they used to. We've looked deep into the problem to understand what's been fixed and what hasn't. Samsung owes its customers an explanation.
Had Samsung's SM951 arrived before we reviewed the Intel SSD 750 Series 1.2TB I think our conclusion might have been a little less favorable for the Intel drive. The SSD 750 may tout NVMe support, but Samsung's SM951 is generally faster while being more affordable.
Crucial SSDs have been among the most reliable and best performing on the market, with last year's MX100 being their greatest hit. Its successor, the MX200 arrived only six months later and along with it Crucial also introduced the even more affordable BX100 series and a new SSD toolbox software. On today's menu is the beefy 1TB MX200 ($470) along with the 500GB BX100 ($190).
Designed for enthusiasts and workstations, the key feature of Intel's SSD 750 Series is its adoption of Non-Volatile Memory Express or NVMe, bringing multiple queues and lower latency with a direct path from the storage to the CPU. The drive is rated to deliver sequential read performance of up to 2.4GB/s with sequential writes hitting 1.2GB/s.
Equipped with 3D TLC NAND, Samsung's 'V-NAND'-based 850 Evo series released last December, stacks layer upon layer of transistors, improving density, endurance and performance, while lowering production costs. Today we have two similarly new drives that focus on different form factors. The 850 Evo mSATA will appeal to compact PC users, while the M.2 will be more sought after by power users.
