Review on 💪 TEAMGROUP T-Force Vulcan G 1TB SSD: SLC Cache, 3D NAND, SATA III, R/W Speed up to 550/500 MB/s by Jason Bell

Not so long ago, a terabyte of flash storage on a single drive was prohibitively expensive, and for all but large enterprise implementations where high performance is required, reliable storage was absolute Need. This is no longer the case. The price per gigabyte of an SSD has fallen significantly in recent years. They were pretty affordable, I bought 3 of these and they make up the storage for my hyperconverged computing environment which is my home lab. I have 3 hypervisors running RHV (Red Hat Virtualization) 4.4. Each is configured with one of these 1TB SATA SSDs providing storage capacity configured with a 256GB NVMe drive with read/write cache. The NVMe capable SATA drives are then pooled as a replicated GlusterFS volume. I've experimented with different Gluster configurations. A striped distributed volume (essentially a RAID0 JBOD array) gives me all 3TB of space and is very fast but offers no redundancy. When configured as a striped volume (essentially a 2TB RAID5 array), read/write speeds dropped slightly, but was still usable as virtual machine storage. I chose a replica volume (essentially a 1TB RAID1 array) that offers the best compromise between performance, reliability, and storage capacity. Technically, the Replica volume is also the only officially supported storage configuration in RHV, but there's nothing stopping you from setting up the Gluster volume the way you want it. For those of you who have no experience with RHV/oVirt, I actually created a storage pool similar to vSAN configured for RAID1 on vmware.locally, read/writes are lightning fast. On certain workloads I can get over 2Gbps when writing. With a hyper-converged storage pool, 1GB of Ethernet connectivity is a bit in the way, but it's enough to run virtual machines. I've made my hyper-converged volumes as performant as possible using flash storage, the only bottlenecks are the network and software. and i'm happy with it. I'm seeing similar read/write speeds to our NetApp flash storage. Overall I'm very happy with it and would recommend it to anyone who needs cheap and fast storage.
