Samsung has introduced its new lineup of datacenter-class SSDs that uses its latest V-NAND flash memory and a SATA interface. The new drives offer up to 7680 GB capacity, consume less power than predecessors including helium-filled hard drives.
The Samsung PM883 SSDs are based on the company’s proprietary controller as well as 64-layer TLC V-NAND memory. The new drives carry 4 TB and 8 TB of raw NAND flash memory to provide 3840 and 7680 GB capacities. Meanwhile, the key feature of the PM883 is not capacity, but very low power consumption when compared to other SSDs: they consume only 2.8 W during read operations and 3.7 W during write operations. To reduce power consumption, the PM883 use several methods: in addition to usage of high-density V-NAND flash memory, they use LPDDR4 DRAM produced using a 10-nm-class process technology. Furthermore, the drives support Power Disable (PWDIS) feature of the SATA 3.3 protocol that enables power management in individual SSDs within a data center. Obviously, to take advantage of the PWDIS, host systems have to support this feature too.
When it comes to performance, the Samsung PM883 can read data sequentially at 550 MB/s and write data at 520 MB/s. As for random performance, the new drives are capable of 98,000 read IOPS as well as 28,000 write IOPS. Meanwhile, the endurance of Samsung’s PM883 SSDs is rated at 5466 TB for the 3840 GB model and 10,932 TB for the 7680 GB SKU.
|Specifications of the Samsung PM883|
|3840 GB||7680 GB|
|Interface||SATA 6 Gbps|
|Controller||Samsung proprietary controller|
|NAND||3D/V-NAND TLC 64-layer|
|Sequential Read||550 MB/s|
|Sequential Write||520 MB/s|
|Random Read (4 KB) IOPS||98,000|
|Random Write (4 KB) IOPS||28,000|
|Endurance||5466 TB||10,932 TB|
|Warranty||3 years (1.3 DWPD)|
|Power Loss Protection||unknown|
Samsung did not disclose MSRPs of the PM883 drives, but since the SSDs are designed primarily for cloud datacenters, their actual pricing will depend on negotiations with particular clients.
Update 3/21: Samsung said that the PM883 SSDs will be covered by a three-year warranty and therefore rated for about 1.3 DWPD (drive writes per day).

Lolimaster - Wednesday, March 21, 2018 - linkNeed 4 of those 8TB to cover my storage need + 1 960Pro for OS/App and 112GB optane for GTAV and swapfile :D
MrSpadge - Wednesday, March 21, 2018 - linkYep, I've also got a bunch of old videos that I practically never watch and which desperately need to go on expensive SSD storage ;)
hypopraxia - Wednesday, March 21, 2018 - linkThat Vampire Elf Porn isn't going to host itself.
Samus - Thursday, March 22, 2018 - linklol
olafgarten - Monday, March 26, 2018 - linkI have still not come across anyone who has a legitimate need for more than 500gb of primary storage.
SleepyFE - Monday, March 26, 2018 - linkSadly gamers. Last game i installed was 50GB and after a few playthroughs the save games were about 20GB. I tend not to delete anything in case i can use the save games in a sequel. Also when a trilogy is complete i might play through the whole thing so i can refresh my in game references, hence all games remain installed.
Luckz - Tuesday, April 3, 2018 - linkWhat game has 20GB saves?
