They are engineered for greater performance and endurance in a cost-effective design, and to support a broader set of workloads.\u003cbr\u003e\u003cbr\u003eEntry SSDs and Performance SSDs have similar read and write IOPS performance, but the key difference between them is their endurance (or lifetime) (that is, how long they can perform write operations because SSDs have a finite number of program\/erase (P\/E) cycles). Entry SSDs have a better cost\/IOPS ratio but lower endurance compared to Performance SSDs. SSD write endurance is typically measured by the number of program\/erase (P\/E) cycles that the drive incurs over its lifetime, listed as the total bytes of written data (TBW) in the device specification.\u003cbr\u003e\u003cbr\u003eThe TBW value assigned to a solid-state device is the total bytes of written data (based on the number of P\/E cycles) that a drive can be guaranteed to complete (% of remaining P\/E cycles = % of remaining TBW). Reaching this limit does not cause the drive to immediately fail. It simply denotes the maximum number of writes that can be guaranteed. A solid-state device will not fail upon reaching the specified TBW. At some point based on manufacturing variance margin, after surpassing the TBW value, the drive will reach the end-of-life point, at which the drive will go into a read-only mode.\u003cbr\u003e\u003cbr\u003eBecause of such behavior by Entry solid-state drives, careful planning must be done to use them only in read-intensive or mixed up to 70% read\/30% write environments to ensure that the TBW of the drive will not be exceeded before the required life expectancy.\u003cbr\u003e\u003cbr\u003eFor example, the 480 GB PM883 Entry drive has an endurance of 683 TB of total bytes written (TBW). This means that for full operation over five years, write workload must be limited to no more than 374 GB of writes per day, which is equivalent to 0.8 full drive writes per day (DWPD). For the device to last three years, the drive write workload must be limited to no more than 624 GB of writes per day, which is equivalent to 1.3 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\u003eCertification\u003c\/td\u003e\n\u003ctd\u003eUL, TUV, FCC, CE, C-Tick, BSMI, KCC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTBW rating\u003c\/td\u003e\n\u003ctd\u003e341\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMean time between failures (MTBF)\u003c\/td\u003e\n\u003ctd\u003e2000000 h\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUncorrectable Bit Error Rate (UBER)\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;
