SM2259 ei ole huononnus.
Currently, most SSDs using Silicon Motion controllers feature either the SM2258 SATA controller or the SM2260 NVMe controller. The SM2258XT is a DRAMless variant of the SM2258. Silicon Motion's new SM2259 SATA controller recently debuted in the Intel SSD 545s, but hasn't been spotted in any other consumer products yet and there are still new SM2258 products being announced. Silicon Motion hasn't shared much information on the SM2259 and it doesn't even appear on their website yet, but thanks to the presentations at FMS we now know that one of the key improvements over the SM2258 is Silicon Motion's second-generation LDPC encoder. Like the SM2260 NVMe controller, the SM2259 uses a 2kb codeword size instead of the 1kb codeword size used by the SM2256 and SM2258 SATA controllers. As a result of the larger codeword size and other changes to the LDPC system, the SM2259 can offer much higher error correction throughput and tolerate a higher error rate than its predecessors. The improved performance comes at the cost of requiring significantly more die area on the controller and higher power draw, but our test results from the Intel SSD 545s indicate these tradeoffs were worthwhile.
Pari kuukautta sitten tuli piristettyä vajaa 10 v vanhaa konetta KingDian S280 120 SSD:llä. Säästöä tuli noin kymppi sen hetken halvimpaan Suomesta saatavaan saman kokoiseen asemaan. Kovaan käyttöön en olisi laittanut mutta eläkeläisen pankkiasiat ja sähköpostit hoitunee tällä yhtä hyvin kuin kalliimmalla. Varmaan ihan hyvät tulokset reilun 16 euron asemaksi.
