We whipped up a general specs images of what to expect from some of our tests. Breaking 100K marks in Vantage is obviously a massive accomplishment, but surpassing the SATA III limits in sequential reads and writes makes my heart skip a beat. When meeting with SanDisk today, I damn near broke out a Harlem Shake.
SanDisk A110 Benefits
- Supports multi-stream for improved user experience in multi-tasking
- Supports TRIM command
- Minimal write amplification
- Tiered Caching - volatile and non- volatile cache (not used today)
- Supports ATA-register and command set
- AHCI Support
- SMART feature supported
- Host independent details of erasing and programming flash memory
- Sophisticated system for error recovery including powerful ECC
- Advanced automated power management
- Dynamic and static wear-leveling to extend SSD life
Initially SanDisk will offer the A110 in two capacity sizes - 128GB and 256GB. The form factor is M.2 2260 and it rides the PCIe 2.0 x2-lane highway. The sequential read performance should be in the neighborhood of 725MB/s (!) and sequential writes are 620MB/s. The claimed IOPS performance is just as impressive with over 110K 4K read with a consumer workload and 73K write IOPS. SanDisk used their advanced nCache on the A110, the flash technology we still feel is the best in the business after a long run testing products like the Ultra Plus and Extreme II.
The claimed performance doesn't meet that of two single 2.5" SATA III SSDs in RAID 0, but it's close enough for a single drive to change the way we define performance SSDs.
The SanDisk A110
The SanDisk A110 256GB sample has three chips on the primary side, two 19nm SanDisk Toggle 2.0 with nCACHE and a new Marvell PCIe to NAND Flash controller.
On the other side, we found two more NAND flash packages with a Hynix DRR3 DRAM buffer.
Enough with the tech talk, let's get down to business and see what the next generation of computers will use for storage.
