Continue to toss this interstellar snails, mainly replacing the mSATA hard disk, replace the memory, CPU grease-coated, hot-swappable boards canceled, in fact, these can also engage in the performance of the machine will not have any effect, but a change They can seek a little psychological comfort only.

Snail Star front panel is fixed with a lock nut, then unscrew the four nuts, front and rear disk tray then fixed at countersunk screws, after removing the hard disk shelf, the board on all exposed.

???

If you spend the hard disk, and do not need to extract the hard drive often, then, can the board and hot-swappable SATA data cable removed, this will save a lot of interior space, turned out to be two large 4P power to four hard drives, I now a power supply line carrying the supply with SATA, a more stable feeling. 3PIN motherboard also has an interface, which can be accessed cooling fan.

???

J1900 is DDR3L, low-voltage 1.35V memory frequency of 1333, so no need to buy a 1600, direct Internet to find Micron DDR3L Article 4G of memory frequency of 1333 put the notebook, the no-name much better than before. Comes mSATA solid state drive more slag, read and write speed is very slow, on the Internet for ads for used Samsung 64G solid state, but if installed NAS system could not really feel any difference.

???

After the change of SSD, reinstall the system, need to be Fast Boot is turned on in the BIOS, if a group of Hui and motherboard supports UEFI, then write directly to the SSD with the write disk tool in PE, if it is U-NAS or OpenMediaVault words with Etcher make U disk installation disk, boot U disk to start the installation, snail interstellar memory is too small, not recommended to install FreeNAS like system.

??

I am currently using a U-NAS, easy installation, also comes Transmission, but the interface does not look good Synology, function suite and did not Synology more, if only to make home storage, U-NAS is competent enough.
