Samsung MZ7L33T8HBLT-00A07 3.84TB SATA 6G 2.5in Read Intensive SSD PM893

The Samsung MZ7L33T8HBLT-00A07 is the 3.84TB model of the PM893 data center SATA SSD. It connects over 6Gb/s SATA, uses Samsung TLC V-NAND, and comes in a 2.5-inch, 7mm case that fits standard server drive bays. Samsung builds the flash, controller, DRAM and firmware in-house for this series and lists power loss protection and end-to-end data protection as standard.

At 3.84TB, the PM893 is the capacity many buyers pick when they want to move a SATA server from spinning disks to flash without changing controllers or backplanes. It is rated at 1 drive write per day, so it belongs in the read-intensive class. Good fits include file and print servers, virtual desktop images, backup landing zones that are read back often, web content stores and departmental databases with modest write rates. Samsung rates the PM893 series at up to 550 MB/s sequential read, 520 MB/s sequential write, 98,000 random read IOPS and 30,000 random write IOPS. Those numbers are close to the SATA interface limit, so a larger drive does not make individual transfers faster, but it does reduce the number of drives and bays you need.

SATA SSDs work on onboard SATA ports, SATA backplanes and most SAS RAID controllers. On HPE, Dell and Lenovo servers you will need the correct hot-plug carrier, and vendor tools may report a generic Samsung drive as third-party. Plan RAID sets with matching capacities, since mixing 3.84TB drives with smaller ones wastes the extra space.

Before you order, confirm:

• Your bays and controller accept 2.5-inch SATA drives
• You have carriers that match the chassis
• Daily writes stay within about 1 DWPD (roughly 3.84TB per day)
• All drives in the array are the same capacity
