SSD Q300 предлагает возможность обновить выгодно систему, в которой ранее использовался жёсткий диск. В данной модели используется 19-нм флеш-память NAND и SSD-контроллер производства Toshiba, поддерживается Zeroing TRIM и Native Command Queuing. В Q300 используются фирменные чипы памяти с 3-битной флеш-технологией NAND. Это значит, что в ячейке памяти сохраняются 3 бита, и плотность хранения существенно возрастает. SSD оснащены также технологией кэширования "Adaptive Size SLC Write" и поддерживают режим Read-only.
Design
The Toshiba Q300 SSD is a standard internal SATA drive. This means it takes the standard 2.5-inch drive design and slaps a SATA port on one of its sides. Like all SSDs released in the last few years, it supports the latest SATA 3 (6Gbps) but will also work with SATA 2 and SATA. The Q300 will fit in any home applications where a standard SATA hard drive, be it a 2.5-inch laptop drive or a 3.5-inch desktop drive, is being used. The Q300 is 7mm thick, but it comes with a 2.5mm spacer in case you need it to perfectly fit into the space of a standard 9.5mm laptop hard drive.
Similar to the case of the Plextor M6V, the Q300 doesn't come with a drive bay adapter bracket for a desktop computer. But this is not the end of the world, as you can safely use an SSD inside a desktop without securing it to the chassis, owing to the fact that SSDs don't have any moving parts. Or you can get a drive bay converter bracket online for a few bucks.
The Q300 includes copy of NTI Echo drive cloning software that you can download from Toshiba's website. Note that you can't download the software right away from the website. Instead, you first have to register with Toshiba and enter your name and a working email address. After that, the download link will be mailed to you, and in the process you will likely opt in to receive unwanted emails in the future. I find this process rather intrusive. Nonetheless, I tried out the software, and it worked as intended. It didn't have as many features or backup functions as some other options, such as Macrium Reflect, which you can use for free without having to surrender any personal information.
Features
The Q300 supports the common features available in most SSDs, including TRIM and garbage collection. (Read more about SSDs here.) On top of that, it also features an adaptive size SLC write cache technology. Essentially, this technology uses a small portion of fast flash memory, called single-level-cell NAND -- the type of memory used in high-end enterprise SSDs -- as buffer for faster write operation.
Like other budget SSDs, the Q300 doesn't support encryption. However, encryption, which protects data in case of theft or loss, is only needed in a corporate or business environment and only works with motherboards that also have this feature. Most home computers don't support encryption in the first place.
