It spins at 7200 RPM, has a 256MB buffer, and sits in a helium-sealed case.\u003c\/p\u003e\n\u003cp\u003eSynology rates it for a 2.5 million hour MTTF and 550TB of workload a year. Persistent write cache helps protect data if power cuts out suddenly. Sustained speed tops out near 254 MB\/s.\u003c\/p\u003e\n\u003ch2\u003eWhy Synology builds its own drive\u003c\/h2\u003e\n\u003cp\u003eSynology tests these drives in its own systems. It also tunes the firmware for DiskStation Manager (DSM). DSM can update the drive firmware along with the operating system, which saves a maintenance step. Synology claims up to 23% faster sequential reads than similar drives in its NAS lineup.\u003c\/p\u003e\n\u003cp\u003eAt 254 MB\/s, one full pass over 12TB takes about 13 hours at best. A 12-bay NAS filled with HAT5300-12T drives holds 144TB raw. Synology lists 4.25 W at idle, so that set idles near 51 W.\u003c\/p\u003e\n\u003ch2\u003eHAT5300-12T specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eSynology\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eSeries\u003c\/th\u003e\n\u003ctd\u003eHAT5300 Enterprise\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eModel number\u003c\/th\u003e\n\u003ctd\u003eHAT5300-12T\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eCapacity\u003c\/th\u003e\n\u003ctd\u003e12TB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eInterface\u003c\/th\u003e\n\u003ctd\u003eSATA 6Gb\/s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eSpindle speed\u003c\/th\u003e\n\u003ctd\u003e7200 RPM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eBuffer\u003c\/th\u003e\n\u003ctd\u003e256MB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eSector format\u003c\/th\u003e\n\u003ctd\u003e512e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eDesign\u003c\/th\u003e\n\u003ctd\u003eHelium-sealed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eSustained transfer\u003c\/th\u003e\n\u003ctd\u003eUp to 254 MB\/s (242 MiB\/s)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eMTTF\u003c\/th\u003e\n\u003ctd\u003e2.5 million hours\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eWorkload rating\u003c\/th\u003e\n\u003ctd\u003e550TB per year\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eIdle \/ active power\u003c\/th\u003e\n\u003ctd\u003e4.25 W \/ 7.83 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e720 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eQuestions about the HAT5300-12T\u003c\/h2\u003e\n\u003ch3\u003eDoes it work in a non-Synology NAS?\u003c\/h3\u003e\n\u003cp\u003eIt's a standard 3.5-inch SATA drive, so it fits other bays.
