It’s interesting how we always find really useful technologies in SSDs focused on the corporate segment. THE Samsung, for example, announced on Thursday (19) the lines PM1733 and PM1735 which, in addition to the large storage capacity, have “anti-death” technology.
The official announcement was made today, but these lines have been in production since last month. They are NVMe and are based on PCI Express 4.0. But what makes them so interesting is the FIP (Fail in Place) technology. With this software, the SSD continues to function even if one of your data storage chips is defective.
In addition to detecting the problematic chip, FIP technology allows the data stored there to be automatically relocated on chips that operate normally, without the application having to be interrupted or lose performance.
There are at least two advantages to this: the SSD does not become unusable due to a defect in a chip; if changing the unit is still desirable, you can wait for the procedure to be done during a maintenance routine.
The two lines are available in two formats: 2.5 inch U.2 and HHHL, that is, in plate format. In both, storage capacities vary widely (and note that Samsung does not round those capacities). Let’s go to them:
- Samsung PM1733 U.2 SSD: 0.96 TB, 1.92 TB, 3.84 TB, 7.68 TB, 15.36 TB and 30.72 TB
- Samsung PM1733 HHHL SSD: 1.92 TB, 3.84 TB, 7.68 TB and 15.36 TB
- Samsung PM1735 U.2 SSD: 0.8 TB, 1.6 TB, 3.2 TB, 6.4 TB and 12.8 TB
- Samsung PM1735 HHHL SSD: 1.6 TB, 3.2 TB, 6.4 TB and 12.8 TB
In both the Samsung PM1733 and PM1735 lines, sequential read and write speeds are 6,400 MB / s (megabytes per second) and 3,800 MB / s on U.2 units, respectively. On HHHL SSDs, the write rate remains at 3,800 MB / s, but the read rate goes to 8,000 MB / s.
Other common features include virtualization software that allows the SSD to be “split” into smaller units for simultaneous access by multiple users, as well as a system based on machine learning to ensure data reliability in very fast read operations.
Basically, what differentiates the Samsung PM1733 line from the PM1735 is the DWPD (Drive Writes Per Day), a parameter that indicates how many write operations the SSD supports per day during its useful life.
The Samsung PM1733 line comes with 1 DWPD, which means that the 0.96 TB version, for example, can have all this capacity rewritten per day. The Samsung PM1735 line, on the other hand, has 3 DWPD (100% of the capacity can be rewritten three times a day). In both, the warranty is five years.
Prices? They were not revealed by Samsung, especially because SSDs for corporate purposes tend to be traded in batches.
