Samsung Ships 15.38TB SSD With Up To 1,200MBps Performance (computerworld.com) 103
Lucas123 writes: Samsung announced it is now shipping the world's highest capacity 2.5-in SSD, the 15.38TB PM1633a. The new SSD uses a 12Gbps SAS interface and is being marketed for use in enterprise-class storage systems where IT managers can fit twice as many of the drives in a standard 19-inch, 2U rack compared to an equivalent 3.5-inch drive. The PM1633a sports random read/write speeds of up to 200,000 and 32,000 IOPS, respectively. It delivers sequential read/write speeds of up to 1,200MBps, the company said. The SSD can sustain one full drive write (15.38TB) per day, every day over its life, which Samsung claims is two to ten times more data than typical SATA SSDs based on planar MLC and TLC NAND flash technologies. The SSD is based on Samsung's 48-layer V-NAND (3D NAND) technology, which also uses 3-bit MLC flash. Also at Hot Hardware

The units in TFS are messed up. So it's 15.38TB... Assuming the stupid new IEC decimal units, not real 2^40 terabytes. But then performance is measured in MBps, or megabytes per second. TFA compares 1,200 with the typical figure of 550 MBps for consumer SSDs, but that's 2^20 byte megabytes measured by benchmarking software. Who knows if Samsung uses the same units, or is trying to screw up with decimal megabytes.

With SSDs, it is possible it is not the decimal units, around half the drives are base 2 sizes from what i have found. I however am not sure how you would arrive at 15.38TB. If I assume is is 16 TIB I get 17.59 TB or 16 TB comes out as 14.55 TiB, so I am not sure where 15.38 TB comes from at all. Perhaps there is some kind of loss to the slack used for reassigning bad bits though.

All SSDs have plenty of spare blocks, so the final size is a decision on how many spare blocks to allocate. Measuring in a power of 1024 makes little more sense than for a hard drive.

I think the reason they're loss common is that this kind of storage density has been pretty uncommon until relatively recently. Drive sizes have grown fast enough that the same 12 or 24 drive front loading shelf met a lot of needs over time.

They say it fits "a 2.5 inch form factor", not "the 2.5 inch form factor". Looking at the picture, it certainly looks like the drive is 'taller' than a normal 11mm or so SSD designed for laptops, taking up a larger volume than normal. Not sure what "the" 2.5 inch form factor allows. While probably not taking up half the volume of a 3.5 inch drive, it may be close enough to not allow more than 2 in the same space, especially given the need for connectivity to the drive for power and data.

Those are rather lopsided performance spec's - random reads more than six times as fast as random writes. There are much smaller SSD's [intel.com] that offer random read/write speeds of 460,000 and 290,000 IOPS, for example.
For some applications the larger, slower SSD's may be fine, but for database applications those random write spec's are pretty lacklustre.
