Western Digital has a new SSD. You don’t want them on your PC
Western Digital showed a new SSD. At first glance it’s not bad, especially in terms of performance. However, the situation is worse with data durability.
A leading American manufacturer, company Western Digitalhas introduced new ones to its offer SSD addressed to the OEM sector, i.e. ready-made computer sets and laptops. We’re talking about a model PC SN5000Swhich is available in the two most popular formats – M.2 2280 and M.2 2230.
Western Digital PC SN5000S has a performance of up to 6000 MB/s
New media use proprietary controller and bones BiCS6these are 162-layer type memories QLC NAND. These are SSDs devoid of DRAM memory. According to assurances, they are to be up to 6 times more efficient than BiCS4. Their special feature is the high data storage density of 15 Gbit/mm2.
Western Digital PC SN5000S uses the interface PCI Express 4.0 x4and the declared efficiency is up to 6000 MB/s for reading and up to 5600 MB/s for sequential writing. It is therefore noticeably more efficient than the older but popular Wester Digital PC SN740 model with TLC chips.
- Western Digital PC SN5000S 512 GB – up to 6000 MB/s for reading and up to 4200 MB/s for sequential writing; up to 500,000 IOPS for reading and up to 850,000 IOPS for random writing.
- Western Digital PC SN5000S 1TB – up to 6000 MB/s for reading and up to 5400 MB/s for sequential writing; up to 750,000 IOPS for reading and up to 900,000 IOPS for random writing.
- Western Digital PC SN5000S 2TB – up to 6000 MB/s for reading and up to 5600 MB/s for sequential writing; up to 750,000 IOPS for reading and up to 900,000 IOPS for random writing.
Of course, despite the improvement in performance QLC technology still has clear lifespan issues. This can be seen in the warranty conditions that WD offers 5 years warrantybut it is limited very low data recording limit – 150 TBW for 512 GB, 300 TBW for 1 TB and 600 TBW for 2 TB. TLC SSDs offer at least twice that.
