These drives offer high endurance supporting up to 10 full drive writes per day (10 DWPD) over 5 years meaning they are ideal for write-intensive applications.\u003cbr\u003e\u003cbr\u003eThis product guide provides essential presales information to understand the SS530 12 Gb SAS SSD offerings and their key features, specifications, and compatibility. This guide is intended for technical specialists, sales specialists, sales engineers, IT architects, and other IT professionals who want to learn more about the SSDs and consider their use in IT solutions.\u003cbr\u003e\u003cbr\u003eThe ThinkSystem SS530 Performance SAS 12Gb SSDs use second generation 3D TLC NAND flash memory technology with a 12 Gb SAS interface to provide a high-performance storage solution in either 2.5-inch or 3.5-inch drive form factor.\u003cbr\u003e\u003cbr\u003eThe 12 Gb SAS drives with 10 full drives writes per day (DWPD) are an excellent choice for applications demanding high write performance, such as High Performance Computing (HPC), High Definition Imaging and Video (HDIV), high data rate analytics and databases, large-scale virtualization, and video on demand content delivery.\u003cbr\u003e\u003cbr\u003eThe key difference between Performance SSDs such as the SS530 SSDs described here and Entry and Mainstream SSDs, is their endurance (life expectancy). SSDs have a huge, but finite, number of program\/erase (P\/E) cycles, which determines how long the drives can perform write operations and thus their life expectancy. Performance SSDs have better endurance than the Mainstream and Entry SSDs, but at a higher cost\/IOPS ratio.\u003cbr\u003e\u003cbr\u003eSSD write endurance is typically measured by the number of program\/erase cycles that the drive can incur over its lifetime, which is listed as TBW in the device specification. The TBW value that is assigned to a solid-state device is the total bytes of written data that a drive can be guaranteed to complete. Reaching this limit does not cause the drive to immediately fail; the TBW simply denotes the maximum number of writes that can be guaranteed.\u003cbr\u003e\u003cbr\u003eA solid-state device does not fail upon reaching the specified TBW, but at some point after surpassing the TBW value (and based on manufacturing variance margins), the drive reaches the end-of-life point, at which time the drive goes into read-only mode. Because of such behavior, careful planning must be done to use SSDs in the application environments to ensure that the TBW of the drive is not exceeded before the required life expectancy.\u003cbr\u003e\u003cbr\u003eFor example, the SS530 1.6TB drive has an endurance of 29.41 PB of total bytes written (TBW). This means that for full operation over five years, write workload must be limited to no more than 16.12 TB of writes per day, which is equivalent to 10.1 full drive writes per day (DWPD). For the device to last three years, the drive write workload must be limited to no more than 26.86 TB of writes per day, which is equivalent to 16.8 full drive writes per day.\u003c\/p\u003e\u003c\/div\u003e\u003cdiv id=\"icepim-attributes\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\u003cth colspan=\"2\"\u003eFeatures\u003c\/th\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMean time between failures (MTBF)\u003c\/td\u003e\n\u003ctd\u003e2500000 h\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHot-swap\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWrite latency\u003c\/td\u003e\n\u003ctd\u003e26 µs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRead latency\u003c\/td\u003e\n\u003ctd\u003e96 µs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRandom write (4KB)\u003c\/td\u003e\n\u003ctd\u003e170300 IOPS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRandom read (4KB)\u003c\/td\u003e\n\u003ctd\u003e239500 IOPS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWrite speed\u003c\/td\u003e\n\u003ctd\u003e1050 MB\/s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRead speed\u003c\/td\u003e\n\u003ctd\u003e1070 MB\/s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eData transfer rate\u003c\/td\u003e\n\u003ctd\u003e12 Gbit\/s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComponent for\u003c\/td\u003e\n\u003ctd\u003eServer\/workstation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNVMe\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterface\u003c\/td\u003e\n\u003ctd\u003eSAS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSSD form factor\u003c\/td\u003e\n\u003ctd\u003e2.5\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSSD capacity\u003c\/td\u003e\n\u003ctd\u003e800 GB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\u003cth colspan=\"2\"\u003ePower\u003c\/th\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\u003ctr\u003e\n\u003ctd\u003ePower consumption (average)\u003c\/td\u003e\n\u003ctd\u003e9 W\u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\u003cth colspan=\"2\"\u003eWeight \u0026amp; dimensions\u003c\/th\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e175 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e15 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth\u003c\/td\u003e\n\u003ctd\u003e100 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e70 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\u003cth colspan=\"2\"\u003eOperational conditions\u003c\/th\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating shock\u003c\/td\u003e\n\u003ctd\u003e1500 G\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating vibration\u003c\/td\u003e\n\u003ctd\u003e3.1 G\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating relative humidity (H-H)\u003c\/td\u003e\n\u003ctd\u003e5 - 95%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage temperature (T-T)\u003c\/td\u003e\n\u003ctd\u003e-40 - 85 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating temperature (T-T)\u003c\/td\u003e\n\u003ctd\u003e0 - 75 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\u003cth colspan=\"2\"\u003eLogistics data\u003c\/th\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\u003ctr\u003e\n\u003ctd\u003eHarmonized System (HS) code\u003c\/td\u003e\n\u003ctd\u003e84717070\u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e","brand":"Lenovo","offers":[{"title":"Default Title","offer_id":55308765135230,"sku":"4XB7A10230","price":3799.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0607\/0190\/0965\/files\/b77814048bba7de2b1a1eac5fa1986ce.jpg?v=1756125430","url":"https:\/\/www.backtotheoffice.co.uk\/products\/lenovo-thinksystem-ss530-800-gb-25-sas","provider":"Back to the Office","version":"1.0","type":"link"}
