Toshiba oznamuje maloobchodní disky SSD s technologií TR200 s technologií 3D NAND

Toshiba has announced their first retail SSDs to use 3D NAND. The new TR200 series will use Toshiba’s 64-layer BiCS3 3D TLC NAND, the first generation of their 3D NAND flash technology to be suitable for mainstream mass-market use. The TR200 series is the successor to the OCZ Trion 100 a Trion 150 SSD, z nichž druhý byl přejmenován na TR150 Společnost Toshiba začala asimilaci identity značky OCZ. Řada TR200 nebude nést název OCZ, ale společnost Toshiba zcela neopouští značku OCZ.

Where the previous Trion/TR series SSDs served as Toshiba’s entry-level SATA offering and split the market with their MLC-based Vektor / VT 180 a VX500, the TR200 will be Toshiba’s only retail SATA SSD for this generation. As with most other SSD vendors, Toshiba is no longer using MLC for new mainstream consumer SSDs based on 3D NAND flash. Unusually, Toshiba’s TR200 will feature a DRAM-less controller design, which typically restricts the performance to only be competitive in the entry-level segment of the SATA market. The controller may be a descendant of the Toshiba controller used in the OCZ VX500, updated to support TLC and larger capacities. However, it’s possible that like previous generations of the TR series, the TR200 is using a re-badged Phison controller—Phison’s S11 this time instead of the S10 used in the earlier generations. The ultra-low-end and low-capacity TL100 that was introduced last year is also not getting a direct successor.

Toshiba’s OCZ VX500 high-end SATA SSD isn’t getting a direct successor based on 3D NAND, but it is not being retired yet either. It remains to be seen whether Toshiba will introduce a NVMe SSD using 3D MLC, but their most likely strategy will be a retail version of the OEM-only XG5 NVMe SSD s 3D TLC. XG5 je nástupcem jak pro XG4 na bázi TLC, tak pro XG3 na bázi MLC, jehož maloobchodní protějšek byl OCZ RD400.

The TR200 carries the same three-year warranty and write endurance ratings as its predecessor. Performance specifications have only changed slightly, with the most significant difference being substantially improved random write performance. Pricing has not yet been announced. The TR200 series will start shipping to retailers this fall. It will compete against Western Digital’s SATA SSDs using the same BiCS3 3D TLC NAND, the new WD Blue a SanDisk Ultra 3D. Intel’s SSD 545s je již k dispozici. Očekává se také, že většina dalších prodejců SSD brzy oznámí nové produkty s 64-vrstvou 3D NAND, které budou dodávány koncem tohoto roku.
