Icy Dock company is the most famous manufacturer of disk cages for HDD and SSD, widely known for its series of metal cases for hard drives ToughArmor, which could drive a car without damaging the drives. Today, when it seems that the world has already completely switched to SSD, and Name M.2 boards are replacing SATA SSDs, there are still reasons for choosing 2.5-inch hard drives. This is a relatively inexpensive volume, which is provided by SATA models with a capacity of 4 TB, and high reliability of hybrid Enterprise HDD, such as the Seagate Exos 10E2400. In particular, SAS SSDs with a thickness of 15 mm are quite common.

A modern NAS is quite capable of protecting itself from most attacks and guaranteeing not only the continuity of the service, but also the inviolability of the stored data. Even with minimal settings and following the manufacturer's recommendations, the NAS can become an impregnable fortress for an attacker, so reliable that you can connect the device directly to the Internet without a Firewall, leave it literally in an unguarded place (which is important for peripheral installations), being absolutely sure that even if it is physically stolen, your data will not be in the hands of competitors and will not be merged into the network.

We have a typical business NAS of the Mainstream class: with two 10-Gigabit network ports, a fault-tolerant power supply unit and an 8-core Intel Xeon D-1541 processor. This is a solution for most large and small organizations, which can be assigned to file sharing on the network, backup and operation of various services.

Now customers have the opportunity to use ZFS in entry-level storage: now you can combine deduplication and SAN connection via FC, configure caching of Cloud storage on a local disk, and synchronize backups between cloud services. Plus, you can mine cryptocurrency directly on the NAS.

What happens if you take two NVME disks: one faster, the other slower, and build a simple RAID from them? Will a faster SSD be able to pull off the speed of a slower one? We will check in working office loads.

Almost today, even budget SSDs for gaming computers can be installed in a working computer or server, and this will not entail any disadvantages compared to Pro-models, but even on the contrary-it will give advantages in speed and reliability. The response time in the SQL pattern for this model is less than 1 ms, which is typical for very expensive storage systems, and the resource and warranty are the same as for top-end branded drives.
