Dell 345-BBXY 3.84TB SAS 12G 2.5in Read Intensive SSD 512e Hot-Plug

The Dell 345-BBXY is a Dell-branded 3.84TB read-intensive solid state drive with a 12Gbps SAS interface, 512e sector format and a 2.5-inch hot-plug form factor for PowerEdge servers. Reseller listings describe it as TLC flash and sell it as a kit with the Dell DXD9H 2.5-inch tray and mounting screws. The Dell part number on the drive label is 7FTC1, which is the number to match when replacing a failed unit.

Read-intensive SAS SSDs like this one suit PowerEdge hosts that need fast random reads with moderate writes: virtualization datastores, file and web servers, VDI, reporting databases and boot or application volumes in RAID sets. Dell does not publish a DWPD figure or performance numbers for this SKU in the sources checked, and the underlying drive manufacturer is not stated. If those numbers matter for sizing, ask for the DPN and firmware on the offered unit. For heavy write workloads, choose a Dell mixed-use SAS SKU instead.

SAS drives need a SAS-capable controller, such as a Dell PERC RAID controller or a SAS HBA, and a SAS/SATA backplane. Unlike SATA, SAS drives will not run on a motherboard SATA port. The 512e format presents 512-byte logical sectors on 4K physical sectors, which current operating systems and PERC controllers handle normally. When adding the drive to an existing RAID volume, keep interface, capacity and endurance class consistent across members.

• Confirm your PowerEdge model uses the 2.5-inch tray style supplied with the kit (DXD9H). Older generations use a different tray.
• Check that your PERC or HBA supports 12Gbps SAS SSDs.
• Match DPN 7FTC1 for like-for-like replacements in an existing array.
