Podrobne o tom, \u010do predstavuje ovl\u00e1da\u010d SM2262EN, sme u\u017e hovorili, ke\u010f sme sa zozn\u00e1mili s ADATA XPG SX8200 Pro.

P\u00f4vodne bol ovl\u00e1da\u010d SM2262EN predstaven\u00fd u\u017e v auguste 2017, s\u00fa\u010dasne s \u201eoby\u010dajn\u00fdm\u201c SM2262, av\u0161ak bol predstaven\u00fd ako jeho \u201epokro\u010dilej\u0161ia\u201c verzia, dod\u00e1vky ktorej mali za\u010da\u0165 nesk\u00f4r. Zrejme sa Silicon Motion chcela zdr\u017eova\u0165 a\u017e do uvedenia 96-vrstvovej TLC 3D NAND na trh, aby potom mohol pon\u00faknu\u0165 ur\u00fdchlen\u00e9 komplexn\u00e9 rie\u0161enia spolu s hustej\u0161ou flash pam\u00e4\u0165ou. Tento pl\u00e1n sa v\u0161ak zr\u00fatil kv\u00f4li zmenen\u00fdm trhov\u00fdm trendom: \u010dipy NAND za\u010dali r\u00fdchlo lacnie\u0165 a v\u00fdrobcovia pam\u00e4te sa rozhodli odlo\u017ei\u0165 zav\u00e1dzanie nov\u00fdch technol\u00f3gi\u00ed.

Ak ver\u00edte form\u00e1lnym \u0161pecifik\u00e1ci\u00e1m, verzia platformy s ovl\u00e1da\u010dom SM2262EN st\u00e1le s\u013eubuje zlep\u0161enie v\u00fdkonu: a\u017e 9 % pri sekven\u010dnom \u010d\u00edtan\u00ed, a\u017e 58 % \u2013 pri sekven\u010dnom z\u00e1pise, a\u017e 14 % \u2013 pri n\u00e1hodnom \u010d\u00edtan\u00ed a a\u017e 40 % \u2013 pri n\u00e1hodnom z\u00e1pise.

\u010co to znamen\u00e1 v praxi, sme u\u017e videli, ke\u010f sme testovali ADATA XPG SX8200 Pro s ovl\u00e1da\u010dom SM2262EN.

Interestingly, the claimed performance of the Transcend MTE220S is somewhat lower than the speeds promised for its similar product based on the SM2262EN controller by ADATA. This is likely due to the fact that, although the MTE220S uses the same hardware-software platform, its design differs from the reference. For its drive, Transcend has designed its own printed circuit board, where it opted to forego the use of a 32-bit DRAM buffer interface in favor of a more economical, 16-bit connection to lower costs. As a result, the maximum speeds for random read and write are reduced, particularly noticeable in the 512 GB version of the drive.<\/p>\n

Nevertheless, the SLC caching in the Transcend MTE220S operates exactly like in other drives with the SM2262EN controller. The cache uses a dynamic scheme, where a portion of the TLC memory from the main array is switched to accelerated single-bit mode. The cache size is configured such that about half of the free flash memory operates in SLC mode. Thus, with high speed, one can write data amounting to approximately one-sixth of the available SSD space on the MTE220S, after which the speed will significantly decrease.<\/p>\n

This can be illustrated with the following graph, which shows how the performance of continuous sequential writing changes on an empty Transcend MTE220S with a capacity of 512 GB.<\/p>\n

In other words, the work with the SLC cache of the Transcend MTE220S is not much different from other drives based on the SM2262EN controller. However, this does not mean that it is similar to the ADATA XPG SX8200 Pro in every aspect. The Transcend offering has a significant advantage of a different kind \u2013 higher permissible overwrite volumes as per warranty conditions. Without loss of warranty, the drive can be completely overwritten with data 800 times, and the 256 GB version \u2013 more than 1000 times. Such claimed endurance indicators allow for the hope that the MTE220S is supplied with top-grade quality flash memory, which means that the actual reliability of the drive will satisfy even those users who still regard TLC 3D NAND with great mistrust.<\/p>\n

Vzh\u013ead a vn\u00fatorn\u00e1 kon\u0161trukcia<\/p>\n

For a detailed introduction, as usual, we chose the 512 GB Transcend MTE220S model. It did not present any surprises in its appearance; it is an ordinary drive in the M.2 2280 form factor, which operates via the PCI Express 3.0 x4 interface and supports the NVM Express version 1.3 protocol. However, the packaging and included accessories of the MTE220S evoke strong associations with cheap mass-market products. Even the budget bufferless SSD MTE110S was sold in a full box, while this new product, positioned as a higher-level solution, was packaged in a blister with nothing else besides the M.2 drive itself. This is very reminiscent of how microSD cards are brought to market and clearly serves the purpose of reducing overhead costs. However, it is unlikely that anyone still chooses an SSD based on its packaging.<\/p>\n

\"Nov\u00fd<\/p>\n

The layout of the MTE220S board cannot be considered typical \u2013 it seems that the engineers at Transcend modified it for some specific needs. At least, the previously reviewed ADATA XPG SX8200 Pro drive, despite using a similar hardware platform, looked completely different. However, the new Transcend maintains the dual-sided arrangement of components, so it may not fit 'low-profile' M.2 slots commonly found in thin laptops.<\/p>\n\n\n\n
